Potential flood and debris hazards at Cottonwood Cove, Lake Mead National Recreation Area, Clark County, Nevada
Otto Moosburner
1981, Open-File Report 80-1216
At Cottonwood Cove, Nevada, most of the existing dikes at the recreation sites are effective in diverting and routing floodflows, up to and including the 100-year flood, away from people and facilities. The dikes across Ranger Residence Wash and Access Road Wash at the mouth divert floods up to the...
Measured sections of the Browns Park Formation (Miocene) in Moffat County, Colorado, 1980
Stanley J. Luft, William L. Thoen
1981, Open-File Report 81-171
Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the...
A stochastic streamflow model of the Platte River at Overton, Odessa, and Grand Island, Nebraska
A.V. Vecchia Jr.
1981, Open-File Report 81-1188
A stochastic model is developed to simulate flows for three seasons (September through February, March and April, May through August) at Overton, Odessa, and Grand Island, Nebraska on the Platte River. The model preserves the first and second order moment properties of the historical flow series, including significant autocorrelations within...
