Rainwater Runoff Estimation using Empirical Formulae Computed in C Programming Software for Puriliya District of West Bengal


Purulia is a drought prone district of India. Monsoonal vagaries along with ustic soils and poor groundwater availability augment the sufferings of the district’s residents from acute water scarcity. The main objectives of study are to identify the needs of rainwater harvesting and the possibilities of group based water distribution policy for the Bandu River basin area. Last ten years rain fall details has been collected from the meteorological department of West Bengal4 and based on the study area soil curve number, runoff coefficient, the runoff has been estimated for the basin through empirical formulae given by SCS Relation Curve number and Aiexander Binnie5,6 method computed by help of C programming software. Facts have been represented through suitable cartographic and statistical techniques, i.e., comparison of rainfall and runoff data. The study concludes rain water harvesting be the viable answer to the threat possessed by drought situation in Puruliya. And using software leads to increase in accuracy and speed of determination of runoff.
