Water Quality and Hydrological Cycle in an Urbanized Hilly Basin

Abstract

Urbanization of basins leads not only to pollution by sewage but also to change of the characteristics of hydrological cycle and water quality of natural cyclic flow-components such as ground water flow and surface flow in the basins. Many studies were used to attend to the load of pollutant by sewage. But rare study attends to the load of ground water flow and surface flow.
The purpose of this paper is to describe the character of an urbanized river basin in hilly land, so then in this paper authors estimate the amount of discharge of dissolved chemical compounds, and explain the characteristics of hydrological cycle in the watershed.
