Critical appraisal of soil conservation service curve number scscn model for enhanced performance

Abstract

One of the biggest challenges faced by water and agricultural newlinemanagers is to secure sufficient food production from the available water newlineresources for growing populations of a particular region This can be achieved newlineby proper water resources planning activities Such planning activities require newlinerunoff estimation as one of the primary inputs Rainfall which is the primary newlinesource gives rise to runoff Natural Resource Conservation Service Curve newlineNumber NRCSCN model formerly named as Soil Conservation Service newlineCurve Number SCSCN model is one of the most popular models in newlinerainfallrunoff modelling It estimates surface runoff or rainfallexcess newlinefrom rainfall using a parameter curve number which is derived from newlinewatershed characteristics and 5day antecedent rainfall newline newline
