Optimal Allocation of Ecological Management Practices in a Hilly Urban Watershed

Abstract

At the face of urbanization, the assessment of the behavior of precipitated water with terrain of varying slopes and varying soil types with or without vegetative cover has gained utmost importance. The fast growing cities and urban hubs clamor for a complete utilization of precipitation thus preventing the extreme situations of incessant floods or drought. This in turn creates an urge for making a study of the behavior of hydrological parameters such as infiltration and runoff with varying slopes and vegetation. These hydrological parameters may also be dependent upon the soil type. In this study, a series of experiments have been performed on an experimental setup known as Rainfall Apparatus and various 3 hydrographs of infiltration flow-rate versus time and runoff flow-rate versus time are plotted from the obtained data thereby drawing certain specific and generalized conclusions. Regression equations with a coefficient of correlation of more than 97 % have been used to define the relationship between infiltration and other parameters.
