Description
Scitus Advanced Geoscience Remote Sensing by Hubert Okelly
Water resources engineering is the quantitative study of the hydro-logic cycle the distribution and circulation of water linking the earth’s atmosphere, land and oceans. Surface runo? is measured as the dif-ference between precipitation and abstractions, such as in? ltration (which replenishes groundwater ?ow), surface storage and evapora-tion. Applications include the management of the urban water sup-ply, the design of urban storm-sewer systems, and ? ood forecasting. Hydraulic engineering consists of the application of ?uid mechanics to water ?owing in an isolated environment (pipe, pump) or in an open channel (river, lake, and ocean). Civil engineers are primarily concerned with open channel ? ow, which is governed by the interde-pendent interaction between the water and the channel. The purposes of this book, includes both water use and water excess management. The fundamental water resources engineering process-es are the hydrologic processes and the hydraulic processes. The hy-drologic processes include rainfall, evaporation, in? ltration, rainfall-runo? and routing, all of which can be further subdivided into other processes. Knowledge of the hydrologic and hydraulic processes is extended to the design and analysis aspects. Water resources development has had a long history basically begining when humans changed from being hunters and food gatherers to developing of agriculture and sett lements. This book builds on that knowledge to present state-of-the-an concepts and practices in water resources engineering.
