Flood Elevations for the Soleduck River at Sol Duc Hot Springs, Clallam County, Washington

Description: Abstract: Elevations and inundation areas of a 100-year flood of the Soleduck River, Washington, were determined by the U.S. Geological Survey for the area in the vicinity of the Sol Duc Hot Springs resort, a public facility in the Olympic National Park that under Federal law must be located beyond or protected from damage by a 100-year flood. Results show that most flooding could be eliminated by raising parts of an existing dike. In general, little flood damage is expected, except at the sout… more

Impact of Changes in Land Use on the Ground-Water System in the Sequim-Dungeness Peninsula, Clallam County, Washington

Description: From purpose and scope: In 1978, the U.S. Geological Survey, in cooperation with the State of Washington Department of Ecology and the Board of Clallum County Commissioners, began a study that would (1) make a general assessment of the water resources of the developed area of the county, (2) identify present and potential water-resource problems in these areas, and (3) make in-depth analyses of selected problem areas. The first two items have been completed and documented in a forthcoming repor… more

Mudflow Hazards Along the Toutle and Cowlitz Rivers from a Hypothetical Failure of Spirit Lake Blockage

Description: From introduction: This report identifies mudflow flood hazards associated with a breach of the Spirit Lake debris blockage starting at a lake elevation of 3,475 feet. The report presents the results of an analysis of what would occur downstream if the blockage were to fail (according to a particular scenario) and if the ensuing flood were then to incorporate sediment to form a mudflow. Observations since the May 18 eruption indicate that in the event of a large flood a mudflow is likely to res… more

Numerical Simulation of Ground-Water Flow in Lower Satus Creek Basin, Yakima Indian Reservation, Washington

Description: From abstract: "A multilayer numerical model of steady-state ground-water flow in lower Satus Creek basin was constructed, calibrated using time-avenged data, and used to estimate the long-term effects of proposed irrigation-water management plans on ground-water levels in the area." It contains maps, graphs, and tables.
