29-Development of Interface for Daily Runoff Assessment from a Watershed.

Abstract

Surface runoff is one of the major components in watershed hydrology. The amount of runoff generated from any watershed depends on the many watershed characteristics such as land use, soil type and its physical properties, topography, etc. These watershed characteristics are often spatial in nature. Besides these, rainfall in the form of time series is another major factor. An interactive interface for runoff assessment has been discussed in this paper, which combine the spatial and temporal data. An interface uses the NRCS CN method, which combine these both factors. The developed interface has incorporated in the DSS for operational water resources planning in a watershed, in which surface runoff is core component. The interface has been tested for small hilly watershed in western India. The estimated daily runoff depth for this watershed shows acceptable agreement with gauged daily runoff for the period of three years (2001 to 2003).
