Effects of coal mining on the water quality and sedimentation of Lake Tuscaloosa and selected tributaries, North River basin, Alabama
E. F. Cole
1985, Water-Resources Investigations Report 84-4310
Lake Tuscaloosa, a reservoir on North River, is the primary source of water supply for the city of Tuscaloosa, Alabama, and surrounding areas. Between October 1982 and September 1983, 14 sites in the North River basin were sampled to determine if surface coal mining has impacted the quality of water...
Discharge ratings for control gates at Mississippi River Lock and Dam 14, Le Claire, Iowa
A.J. Heinitz
1985, Water-Resources Investigations Report 85-4261
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 14, at Le Claire, Iowa, were developed from current-meter discharge measurements made in the forebays...
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...
Contributions of suspended sediment from highway construction and other land uses to the Olentangy River, Columbus, Ohio
D.R. Helsel
1985, Water-Resources Investigations Report 84-4336
Highway construction within the Olentangy River flood plain in Columbus, Ohio, was projected to be a large source of suspended sediment to the river system. A monitoring program was begun by the U.S. Geological Survey in 1978 to quantify the implacts of construction process. Sediment information was collected daily at...
An evaluation of the crest-stage gage program in Louisiana
R.A. Herbert, D.D. Carlson, G.J. Wiche
1985, Water-Resources Investigations Report 84-4204
The crest-stage gage program in Louisiana was evaluated to determine if the data were adequate for use in developing regional flood-frequency equations and to determine if any crest-stage gages could be discontinued. An abundance of data at many crest-stage stations and a lack of data for urban area and flat-slope...
Benthic invertebrates in selected streams of the Piceance Creek basin, northwestern Colorado, water years 1977-81
K.J. Covay, H.E. Stranathan, R.L. Tobin
1985, Water-Resources Investigations Report 84-4138
Data from the periodic collection of benthic invertebrates at six streamflow stations in the basin during water years 1977-81 are presented and summarized. A total of 162 genera from 8 insect orders and 8 non-insect orders were documented. Numbers of organisms per sample ranged from 0 to 3,700. Counts generally...
Evaluation of the Mission, Santee, and Tijuana hydrologic subareas for reclaimed-water use, San Diego County, California
J. A. Izbicki
1985, Water-Resources Investigations Report 85-4032
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of treated municipal wastewater (reclaimed water). Groundwater quality has been impacted by agricultural water use, changes in natural recharge patterns, seawater intrusion, and groundwater movement from surrounding marine sediments. Groundwater...

Validity of Darcy's law under transient conditions
C.E. Mongan
1985, Professional Paper 1331
Darcy 's Law, which describes fluid flow through porous materials, was developed for steady flow conditions. The validity of applying this law to transient flows has been mathematically verified for most ground-water flow conditions. The verification was accomplished through application of Hankel transforms to linearized Navier-Stokes equations which described flow...
