Efficiency Assessment of Fuzzy logic membership models for evaluation SCS rainfall-runoff (Acase study: Kameh river watershed)
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 2
Abstract
This paper introduces a fuzzy rule-based model to estimate runoff in semi-arid regions(Kameh river watershed) using the Soil Conservation Service Curve Number model. In this study factors such as: Land used and hydrologic soil group are considered, to determine direct runoff or excess precipitation in the in Kameh river watershed the North East part of Iran. Thematic layers for the above parameters were prepared, in a RS environment by the means of Fuzzy logic (bell-shaped and linear membership function) and Boolean Methods. The evaluation of runoff derived from fuzzy and Boolean methods show that the calculated runoff closer to the measured runoff in the watershed but bell-shaped membership function is the best linear membership function and boolean method for application purposes.
