Honduras Flood Mapping
Honduras is currently (2001) rebuilding its housing and infrastructure that was destroyed by Hurricane Mitch. To plan responsibly and minimize damage during future floods, the Honduran government needs reliable maps of the areas and depth of inundation by the 50-year flood, the design flood chosen for this project. A systematic method for defining areas and depths of inundation is needed that can...
Water Resources Inventory Area 1 Watershed Management
In recent years, increased use of ground- and surface-water supplies in watersheds of Washington State has created concern that insufficient in-stream flows remain for fish and other users. In response, the Washington State legislature passed the Watershed Management Act of 1998 (ESHB 2514; see also Ch.90.82 RCW - Watershed Planning), which encourages and provides some funding for local watershed...
Puyallup Flood Alert
The Puyallup River Basin lies mostly within Pierce County, Washington, and contains 972 square miles of land ranging in elevation from zero at its mouth in Puget Sound to 14,408 feet at the top of Mount Rainier. The cities of Tacoma, Puyallup, Sumner, and Orting are some of the population centers located in the basin. To protect lives and property in the basin, Pierce County needs accurate...
Highway Storm-Water Detention
In some areas of the state, the Washington State Department of Transportation (WSDOT) sometimes directs the storm-water runoff from highways into detention basins that store the water until it infiltrates into the ground. Because most of the water eventually percolates to the water table, and because runoff from highways can contain contaminants, using roadside detention basins may degrade ground...
Elwha-Morse Watershed
Have increased demands for Washington State's ground water and surface water left sufficient stream flows for fish and other uses? To find out, the state's Watershed Management Act of 1998 (ESHB 2514) confers on local people the responsibility for conducting local watershed planning. The Elwha-Morse Watershed area was formed out of the western part of Water Resources Inventory Area 18 (WRIA 18) in...
Probability Flows for Streams in Eastern WA
Under Washington regulations, bridges, culverts, and other stream-crossing structures need to be designed with fish passage in mind. For culverts, maximum flows cannot exceed a 10-percent exceedance probability flow (the flow that is equalled or exceeded 10 percent of the time) when fish are migrating upstream. To help the Washington Department of Natural Resources manage its culverts at more than...
