L.C. Kjelstrom
1988, Water-Resources Investigations Report 87-4063
Croplands in the semiarid central part of the Snake River Plain are dependent on the availability of irrigation water, most of which comes from the Snake River. Allocation of irrigation water from the river requires that gains and losses be determined for American Falls Reservoir, Lake Walcott, and Milner Lake....
Simulation of three lahars in the Mount St Helens area, Washington using a one-dimensional, unsteady-state streamflow model
Antonius Laenen, R. P. Hansen
1988, Water-Resources Investigations Report 88-4004
A one-dimensional, unsteady-state, open-channel model was used to analytically reproduce three lahar events. Factors contributing to the success of the modeling were: (1) the lahars were confined to a channel, (2) channel roughness was defined by field information, and (3) the volume of the flow remained relatively unchanged for the...
