Cherry Creek Model Background


The original USACE Cherry Creek HEC- 1 model contained 22 sub-basins. The real-time model represents all 22 basins using the original unit hydrographs. The Cherry Creek model uses Green Ampt to estimate the infiltration in the basin which was used in the original model.

Methods Used
• Thiessen Polygon Rain Gage Weighting
• Green Ampt Infiltration Method
• Muskingum Routing Channel Routing
• Modified Puls Reservoir Routing

Cherry Creek sub-basins were modeled in the Real-time model in the same configuration as the HEC-1 model.
