There is a limited number of reference books in the worldwide literature in the field of water resources engineering since it is too ambitious to confine the various aspects of this field in a single book. Actually, there are many books which cover only the fundamental aspects of some important topics of water resources engineering.

Descriptive fluid mechanics and the subject matter of hydrology are not covered in the book as the reader is assumed to have basic notions in these areas. Chapters include concise information about the planning, design and construction of water resoruces systems as well as economical aspects and currently practiced specifications. A number of solved and exercise problems are presented at the of each chapter in SI units. Some computer programs are also provided for practical applications. It is believed that this book will be useful for undergraduate or graduate civil engineering students as well as for practicing engineers. The author will appreciate comments and criticism from readers.
