Hydrology and Hydraulic Systems
Water resources are developed either to use or to control groundwater and surface water flows. A developmental activity for the use of water comprises studying the availability of and demand for water and contemplating a project that can meet the expected needs from available supplies by means of engineering works and nonstructural measures.
Water con-trol activities are concerned with regulating the rate of water supply in order to improve conditions within an area. The purpose of the facilities provided by a project is to vary the quantity and quality, time of supply, and place of use of the water resources in accordance with need. Developing a project involves the design and arrangement of structural compo- nents, along with nonstructural measures, if any, to serve the intended purpose.
This book aims to provide a basic understanding of all the quantitative elements that are involved in the formulation of a water development project. The process of develop-ment can be explained by the following sequence of questions. The book is devoted to answering these questions.
