Boise River Flood Simulations Computer animations showing simulations of future scenarios and flood risks for the Boise River were presented at the Treasure Valley Water Summit (January 2002). This collaborative research undertaken with the USGS, City of Boise and the US Corps of Engineers and was funded by FEMA, Idaho Bureau of Disaster Services, USGS and the City of Boise. Simulation of Sediment and Flow in the Coeur d'Alene River System The CER completed a demonstration for the Idaho Department of Environmental Quality of how computer models could be used to assist scientists and managers to make decisions on the sediment management issues on the Coeur d'Alene River and Lake. Simulation of Flood Induced Removal of Alluvial Fans from Tributaries of the Kootenai River The Construction of Libby Dam in 1972 significantly altered the hydrograph, fish migration patterns, temperatures, nutrient availability and sediment transport below the dam. Many of the tributaries in the canyon portion of the Kootenai River have experienced interstitial flow in the summer time due to the development of large alluvial fans and low water levels. Fish biologists have noticed a declining trend in native salmonids in the Kootenai River over the past few decades. The hypothesis is that since the change of the flow regime due to the construction of Libby Dam an increased aggradation has occurred at alluvial fans which can impact fish passage into tributaries. Twelve Mile Reach of the Salmon River at Challis, Idaho The project's primary objective is holistic reach-wide improvement of Chinook salmon habitat through protection of floodplain, slough, and side-channel processes, improving bank stability, promotion of a dynamic channel equilibrium and return to a natural sinuosity while protecting critical structures. The University of Idaho is gathering and analyzing background information for use in developing restoration design plans and to prepare a hydrodynamic model for simulating discharge, sediment and temperature through the system in order to demonstrate to landowners and other decision makers the expected results of proposed restoration measures. Strategies for Thermal Restoration of a Chinook Salmon Spawning and Rearing Stream Using a Heat Transport Model A heat transport model, a combination of a hydraulic and a heat balance model, implemented in the computer program AQUASIM, is being used on Red River to investigate the effects of different scenarios in stream temperature behavior. Therefore, it is not only necessary to monitor stream temperature and meteorological parameters, but also to survey hydraulic parameters and streambed geometry. The results of the modeling work will be used to develop strategies for thermal stream restoration.
