Nusret Şekerdağ The processes applied in the treatment of wastewater are constantly evolving and changing. In addition, the disposal of treatment sludge formed in treatment plants is of particular importance.
Domestic wastewater from the final collector of the city sewerage network must be treated before being discharged to the receiving environment. For this purpose, mechanical, biological and chemical methods are used in the treatment of wastewater. Applications of these methods are given in this book.
Screens, grit traps, oil traps and pre-settlement pools in mechanical treatment, in biological treatment; Calculations have been made for many different alternatives such as activated sludge aeration ponds, trickling filters, rotating biodiscs, membrane bioreactors, stabilization and mechanically aerated ponds, and many sample problems have been solved at the end of each chapter.
In sludge disposal, many alternative applied problems have been made with the aim of dewatering the sludge.
At the end of the book, an applied project is designed and calculations are given for different units one by one.
In addition, the hydraulic calculations of the treatment plant were made in detail and the hydraulic profile of the treatment plant was drawn.
Finally, hydraulic calculations of the sewage sludge pipes were made and the sludge hydraulic profile was given.

Uğur Ersoy, Güney Özcebe, Erdem Canbay Reinforced concrete is different from other building materials. This material, which is not homogeneous, whose behavior depends on time and load history, and is not linear-elastic, has been tried to be put under the cover of classical theories for many years. However, reinforced concrete has not been put under these covers and has continued to exhibit its unique behavior. Therefore, a contemporary and realistic education, a contemporary regulation must definitely be based on behavior and bearing capacity. Behavior can only be learned through experimental studies.

Considering all these reasons, priority was given to the Structural Mechanics Laboratory when METU was established in the late fifties. In the reinforced concrete education that started in 1959 at METU, behavior and bearing capacity have been indispensable for this education.

Of course, domestic and foreign sources were also used in the creation of this book, which has been printed in numerous editions. However, in each section, what was learned from experimental research conducted at METU Structural Mechanics Laboratory and calculation methods developed based on the experimental results are also presented to the reader.

This book was first published in the seventies under a single name - Uğur Ersoy - then Güney Özcebe joined the authorship, followed by Erdem Canbay. This development emphasizes the importance of teamwork.

Bülent Akbaş, Onur Şeker, Hüseyin Türk In recent years, two new regulations regarding the design of steel structures, connections and structural elements have entered into force in our country: 1) Regulation on Design, Calculation and Construction Principles of Steel Structures - ÇYTHYEY, (2016); 2) Turkey Building Earthquake Code, TBDY : Chapter 9 – Special Rules for the Design of Steel Building Structural Systems Under the Impact of Earthquakes (2019). Among these regulations, ÇYTHYEY proposes a force-based evaluation and two design approaches (Design with Load and Strength Factors and Design with Safety Factors) in the design of steel structural elements and combinations. TBDY: In Chapter 9, there are principles of earthquake resistant steel structure design, in which significant changes were made after the 17 January 1994 Northridge earthquake.
With the entry into force of these regulations, the need for two types of resources regarding steel structure design has increased in our country: a) Examples of how the principles and design criteria in the regulations emerged and how they will be applied; b) Design tables and charts to assist engineers in practice. This handbook has been prepared to meet the second type of resource need. These design tables and charts, similarly prepared by the American Institute of Steel Construction, have been prepared in this handbook as design tables for European profiles that are widely used in our country.
The design tables in this handbook have been prepared for different steel grades in accordance with the Design with Load and Strength Factors (YDKT) approach, and the sections are organized as follows:
cross-sectional features,
Ductility and compactness requirements,
Design of elements under bending and shear effect,
Design of elements under axial compression and tension,
Design of elements in compound bending effect.
It is thought that the tables in the book can be easily used by civil engineers in the design of steel structural elements, in the undergraduate and graduate level Steel Structures courses in the Civil Engineering and Architecture Departments, in project and homework studies.
In this first volume of the handbook, a limited number of tables of I-profiles have been created. In the second volume, which is being prepared, it is planned to prepare design tables for different profiles and cross-sections.

Ferruh Yıldız Many problems in today's cities; It is associated with poverty, inequality, pollution, unemployment, difficulties in accessing work, goods and services, low social cohesion, and poor quality of housing and other areas. On the other hand, city planning also has an impact on the social, economic and physical environments and the way cities operate.
In our country, there are more than 200 laws, statutes and regulations that directly or indirectly concern development activities. Therefore, more than 20 organizations at the national and regional level have authority as the implementer and supervisor of so many legislations. Here is one of the main reasons why an effective planning and implementation cannot be done in our country; It is the problem of institutionalization, coordination and lack of effective supervision caused by the structure of the existing planning system between the planning and implementation levels.
In this work; In parallel with the urbanization policies in our country, the necessary planning, implementation and legal bases have been tried to be given in order to produce the housing and residential environment of sufficient quality that the population needs.

Cüneyt Yavuz Engineering, a word derived from the combination of the Latin words ingenium and ingeniare and meaning "to design something clever", is an economical way to design and build structures, machines, devices, hardware and software systems, materials and related processes that make people's lives easier, improve their quality of life and safety. It is the art, discipline and profession of synthesizing social and environmental knowledge with mathematical and scientific methods and putting them into practice.
Civil engineering design and applications, which also means civilization engineering, are as old as human history. In the past, structures were built for shelter, nutrition, protection from predators and environmental influences. Today, civil engineers have an important role in making low-cost, effective, reliable and functional structures by combining safety, economy and functionality parameters at an optimum level according to different criteria.
This book is both a good textbook and a useful resource by examining the basic calculation methods within the scope of civil engineering and the most up-to-date and innovative construction techniques. The important, up-to-date and key information in the content of the book will be a good start for civil engineer candidates in expressing their work in the near future in more technical ways and gaining a solid self-confidence in the context of engineering.

İbrahim Gürer, Ali Günyaktı Hydrology; examines the cycle, distribution and properties of water on Earth. In this period, when climate change scenarios are interpreted more frequently and more carefully, engineers who will be involved in the planning and preparation of projects necessary for the development of water resources and their use for different purposes, need to better recognize the country's water resource, which is a vital value, and use it very carefully.
Despite being located in the most tense region of the world in terms of regional distribution of water resources, Turkey's current water capacity, which is still touted as a water-rich country, needs to be updated rapidly in terms of quantity and quality. Today's problem, in which the temperature tends to increase as well as the decrease in precipitation, is defined as "Global Climate Change". In particular, it is still debated how much of the average annual precipitation goes into useful flow and how much of it feeds groundwater resources. In addition to the technical accuracy of the designed water structures, the effective evaluation of hydrological data, the correct interpretation of possible climate changes in the future is essential.
It is aimed that engineering students have sufficient and correct knowledge about water. In the book, the main topics of engineering hydrology and the solved problems integrated with the topics are given. In addition, problems that can be given as homework are also added.
“References” and “Index” consist of both historical and current information sources. It has been prepared to provide a starting point for those who want to access more detailed information.
The authors, who were engineers of the period when meeting the agricultural product needs of the society with the country's own water and soil resources was the main strategy, believed that according to the changing environmental and eco-hydrology conditions in recent years, not only humans but also other living creatures of nature should be granted the right to live, they were more sensitive to the environment and ecological balance. young colleagues are happy to see him grow.

Serdar Selamet Fire is a natural disaster that has an impact on buildings as serious as an earthquake. Fire engineering is a branch of research that combines fire science, heat transfer, materials science and civil engineering. The mechanical behavior of structures at high temperatures caused by fire is different from traditional building static calculations and the purpose of fire engineering is to reduce the destructive effects of a possible fire on the structure. There are almost no studies in the literature on fire engineering in Türkiye. Today, the importance of fire engineering and the need for well-equipped fire engineers are increasing, and the theoretical information in this book will be an important resource for civil engineers and architects who want to specialize in fire engineering. The calculation methods in the book require undergraduate level knowledge of heat transfer, fluid mechanics, as well as mechanics and statics.

Durmuş Ali Açıkel, Mustafa Altın, Atila Dorum The construction of the facilities, which have been built to meet the needs of living things from the existence of humanity to the present, will continue until the day when humanity will disappear. At every stage of this construction process, there will be the issue of producing buildings of certain standards and quality.
In order to produce buildings with the standards and quality that are felt today, the necessary technical staff should be trained in the relevant departments of the universities and sufficient technical education should be given to them. In our country, the works used in the provision of this education include subjects from very different and different fields in the whole of academic studies; It eliminates the opportunity for students to find the information they need in a single book. The work in your hand has been prepared on the basis of the lack of compact source books needed in this field.
In this context, the book is in accordance with the curriculum of the building and architectural knowledge courses of the Civil Engineering departments, in addition to the Building Technology I and II course curricula taught in the Construction Programs of Vocational Schools. In addition, the book is a work that can provide technical-formal guidance to the technical staff dealing with construction work in the market during the production of buildings.

Serkan Yıldız, Serkan Kıvrak, Gökhan Arslan The emergence of the idea of building in history, along with mental and social developments, has become indispensable for people in meeting needs such as construction, shelter, drinking water, energy and transportation. Effective methods and forms of management applied according to the conditions of the day are of great importance on the basis of the successful presentation of the structures that have been implemented from the past to the present. With the development of modern techniques and technologies, the success of construction projects, which have turned into a complex process today, depends on effective project management.
We see that the literature on the "Construction Management" department, which was born quite late compared to other disciplines and only budded in the second half of the 20th century, is quite limited and fragmentary in our country. We believe that our book, which comprehensively covers the basic management concepts, principles and practices that contribute to the success of construction projects, and is supported by the latest developments and current examples in the field of construction management, will fill the gap in this field and will be a useful resource for all construction professionals, especially civil engineering students.

Mehmet Yener Özkan Soil mechanics and foundation engineering have traditionally studied the behavior of soils and foundations under static loads. On the other hand, soil dynamics can be affected by earthquakes, wind, heavy traffic, machines that produce harmonic or pulsed movements, construction activities such as pile manufacturing, soil improvement, explosions in mines, etc. It deals with the behavior of soils and foundations under dynamic loads caused by Improvements in soil dynamics intensified especially after the 1964 Niigata Earthquake, and engineers tried to better understand the behavior of soils under such loads in order to create safer design methods.
This book has been prepared with the aim of guiding students, engineers and colleagues who want to learn about the subject of soil dynamics, starting from the basic concepts, the behavior of soils under dynamic loads is tried to be presented in a general framework, and the subjects are introduced to engineers who want to learn more. has been studied.

Ferhat Özcep The relationship between soil, earthquake and constructions (static and dynamic loads) is an interactive relationship. On the one hand, earthquake waves and constructions change the strength properties of soils (for example, decrease in bearing capacity, slope failures, settlements, etc.), on the other hand, soils can cause damage to constructions by changing the amplitude and frequency characteristics of earthquake waves (amplifying). Although “floors” is the youngest and smallest unit of the world, it has a great importance in terms of its relationship with our cities and constructions and its effects on our lives. Urban planning stands out as an important study in expanding urban areas as a result of population growth. In order to improve the general welfare and quality of life of the society, it is necessary to achieve a balance between human settlements and the components/dynamics of the earth, whether at the macro or micro level. “Soil investigations” to be carried out both within the scope of large-scale urban planning applications and in the context of small-scale structural engineering are one of the important stages in establishing this balance. All studies in this direction have to be multidisciplinary in character by optimizing various human needs in harmony with the natural environment. This work has two main target audiences of equal value: the first is geophysical engineers with an interest in geotechnical, and the second is civil (geotechnical) engineers with an interest in geophysics. If engineers working in both fields know the limits of their "authorities and responsibilities", there are endless benefits in broadening the horizons of their "knowledge". In this context, besides the usefulness of this work for our colleagues who are geophysical engineers and civil (geotechnical) engineers, geological engineers working in the field of engineering geology, mining engineers working in rock mechanics and/or gallery-tunnel construction projects, and environmental engineer colleagues who are interested in environmental geotechnics/geophysics. We think that it will also be beneficial for urban planners/architects who are interested in microzonation studies within the scope of urban planning/transformation/renewal projects.
The book was revised due to its second edition, and some new additions were made to some sections. In addition, two topics that were not in the first edition were added. These; “Turkey Building Earthquake Code (2018): Principles for Design Under the Impact of Earthquake” and “Investigations on Contaminated Soils: Environmental Geotechnics and Geophysics”.
