SIMULATION OF THE RAINFALL – RUNOFF MODEL IN HEC HMSAND CALIBRATION WITH OBSERVED DISCHARGE DATAHEC HMS was run with 2 meteorological model‣5 minute rainfall intensity data for Tropical Storm Nicole measured atthe Hope discharge station‣5 minute rainfall intensity data from raingauge at Hope dischargestation for the month of June 2011.The SCS loss method and basin lag were used as other input data.Basin lag was determined using SCS formula:TL =L^0.8(SCN+1)^0.7/1900*Y^0.5 where, L= length of the longestflowpath, SCN = (1000/CN -10) , Y = Slope .Model calibrated with observed discharge data from hope dischargestation.
