Using the DWOPER Routing Model to Simulate River Flows with Ice.

Abstract

The flow routing model of the National Weather Service entitled DWOPER (Dynamic Wave Operational Forecast Program) is examined with regard to the modifications required to include the effect of river ice on the flow variables of water level and discharge. Difficulties in modeling the ice effects are described. Example model output is presented showing the transient effects introduced by imposition or removal of the ice cover from an otherwise uncovered flow.
