The SCS curve number (SCS-CN) method has gained widespread popularity for simulating rainfall excess in various events due to its simplicity and practicality. However, it possesses inherent structural issues that limit performance accurately infiltration over time. objective of this study was develop a modified CN with temporally varying intensity (MCN-TVR) by combining soil moisture accounting...

Water is one of the most valuable natural resources and a vital component socioeconomic development nation. in India throughout world are under lot stress as result limited supply rising demand. availability region can be better estimated using rainfall runoff relationship. Runoff mostly produced rainfall, which significant part hydrologic cycle. In this study, rainfall-runoff relation Bamnidhi...

parameters as interception, infiltration, water storage on surface holes and soil profile, evapotranspiration are factors of loss water in a watershed and avoid from changing of precipitation to runoff. in this study, by use of hec-hms model and comparison of results of different methods of precipitation loss evaluation (initial and constant, green & ampt, scs curve number, deficit & constant a...
