Modeling the runoff process in urban areas

Abstract

In recent years, concern about the physical environment and its management has grown rapidly. This is reflected in the increasing attention given to the planning process. The growth and expansion of urban agglomerations represent a typical aggregation of some of man's activities having a marked environmental impact, such as air pollution, noise pollution, etc. Perhaps most vital among the different aspects of impact remains the water pollution. Urban hydrology studies portions of the hydrologic cycle, as modified by the presence of urban environments. Urbanization accounts for an increase in the total amount of runoff due to the increase of imperviousness of the drainage basins, thus aggravating the situation in flood‐prone areas. Equally important, the quality of the runoff waters is a concern, and more specifically its pollution effect on the receiving bodies of water, rivers, lakes, and groundwater recharge. The important recent research effort on the various aspects of these problems can be traced in ...
