Determination of roughness coefficients for streams in Colorado
R.D. Jarrett
1985, Water-Resources Investigations Report 85-4004
Most hydraulic calculations of flow in channels and overbank areas require an evaluation of flow resistance, generally expressed as Manning 's roughness coefficient. The degree of roughness depends on many factors. The report summarizes and relates several methods of estimating roughness and presents additional channel-roughness verification data on higher-gradient streams...

Four water-quality samples were collected from each of nine monitor wells...
Design of a sediment data-collection program in Kansas as affected by time trends
P. R. Jordan
1985, Water-Resources Investigations Report 85-4204
Data collection programs need to be re-examined periodically in order to insure their usefulness, efficiency, and applicability. The possibility of time trends in sediment concentration, in particular, makes the examination with new statistical techniques desirable. After adjusting sediment concentrations for their relation to streamflow rates and by using a seasonal...

Ground-water quality in the Santa Rita, Buellton, and Los Olivos hydrologic subareas of the Santa Ynez River basin, Santa Barbara County, California
S. N. Hamlin
1985, Water-Resources Investigations Report 84-4131
Groundwater quality in the upper Santa Ynez River Valley in Santa Barbara County has degraded due to both natural and anthropogenic causes. The semiarid climate and uneven distribution of rainfall has limited freshwater recharge and caused salt buildup in water supplies. Tertiary rocks supply mineralized water. Agricultural activities (irrigation return...
Transit losses and traveltimes for water-supply releases from Marion Lake during drought conditions, Cottonwood River, east-central Kansas
