Mario Fernandez Jr., C. L. Goetz, J.E. Miller
1984, Water-Resources Investigations Report 83-4182
A one-dimensional, steady-state, water-quality model was developed for a 30.0 mile reach of the Hillsborough River to evaluate water-quality conditions to be expected from future development. The model was calibrated and verified using data collected under critical base-flow conditions in April and December 1978. Dissolved organic nitrogen, nitrate nitrogen, and...

J. M. Gerhart, G.J. Lazorchick
1984, Water-Resources Investigations Report 84-4327
Secondary openings in bedrock are the avenues for virtually all ground-water flow in a 626-sqare-mile area in Lancaster and Berks Counties, Pennsylvania. The number, size, and interconnection of secondary openings are functions of lithology, depth, and topography. Ground water actively circulates to depths of 150 to 300 feet below land...

1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
Preliminary study of the aquifers of the lower Mesilla Valley in Texas and New Mexico by model simulation
J. S. Gates, D. E. White, E. R. Leggat
1984, Water-Resources Investigations Report 84-4317
The aquifers in the lower Mesilla Valley of Texas and New Mexico provide water for irrigation, industrial use, and municipal supply. At present (1984), the shallow aquifer is used principally for irrigation. The medium-depth aquifer (the top of which is about 160 to 260 feet below land surface) and deep...
Cost effectiveness of the U.S. Geological Survey's stream-gaging program in Illinois
D. M. Mades, K. A. Oberg
1984, Water-Resources Investigations Report 84-4123
Data uses and funding sources were identified for 138 continuous-record discharge-gaging stations currently (1983) operated as part of the stream-gaging program in Illinois. Streamflow data from five of those stations are used only for regional hydrology studies. Most streamflow data are used for defining regional hydrology, defining rainfall-runoff relations, flood...

An assessment of nonpoint-source discharges, streamflow, and water quality in Onion River, Wisconsin
S. J. Field, R.A. Lidwin
1984, Water-Resources Investigations Report 84-4066
The Onion River in eastern Wisconsin was studied during the 1979 and 1980 water years to define the relationship between water quality and streamflow. Agricultural nonpoint-source discharges in the lower part of the Onion River are suspected of contributing significantly to degradation of water quality. Two streamflow water-quality monitoring stations were...

L.R. Frost, L.J. Mansue
1984, Water-Resources Investigations Report 84-4037
A hydrograph-shifting method for estimating monthly and annual suspended-sediment loads was applied to suspended-sediment records for 12 streams in Illinois. Transport equations for each station were developed and synthetic sediment-discharge hydrographs were then generated by using these transport equations and records of daily streamflow. Hydrographs were shifted to measured values...
