Measurement With [HEC-2] And [HEC-6]
Computer Models For Koohsefid River

Abstract
Koohsefid River is located in the southwest of Mahalat City in the Markazi
Province of Iran. [HEC-2] and [HEC-6] computer models were used for the
investigation of flood events, water surface profiles and erosion sedimentation
with different return periods for Koosefid River respectively. Based on the
results obtained from [HEC-2] a high correlation is shown with data observing
by floodmark. Erosion and sedimentation in the river with [HEC-6] model uses
different formulas for such prediction. To verify the accuracy of these formulas,
measurement of sediment in hydrometry station was also performed. Toffaleti’s
formula using fall velocity introduced by the Interagency Committee on Water
Resources (I.C.W.R) approach shows the highest correlations with measured
values.
