Artificial Recharge in the Northern Part of Chino Ground-Water Basin, Upper Santa Ana Valley, California
Purpose and Scope: The purpose of this study was to evaluate the geohydrologic characteristics that influence sustained artificial recharge and to determine long-term infiltration rates in the northern part of Chino ground-water basin. Results of this study will help management to design and implement a recharge-recapture system in Chino Basin. Nine test holes were drilled, long-term infiltration tests were made, and drillers' logs and water-level data were evaluated to determine the probable effects of recharging the ground-water basin. The study was concentrated in the northern part of Chino Basin, where recharge is proposed.

An Assessment of the Collection and Analysis of Hydrologic Data by Private Contractors for the U.S. Geological Survey
From abstract: During fiscal years 1978 through 1981, the U.S. Geological Survey contracted for the acquisition and analysis of hydrologic data from 104 surface water stations, 26 ground water stations, and 15 precipitation gages as well as for several hundred miscellaneous surface water measurements of flow and water quality. The work was performed in Montana, North Dakota, Wyoming, Utah, New Mexico, and Oklahoma, terminating at the end of the fiscal year 1981. This report is an assessment of this contracting effort from the standpoint of cost and of quality control measures employed to ensure an acceptable product.

Backwater and Discharge at Highway Crossing with Multiple Bridges in Louisiana and Mississippi
Purpose and Scope: The principal objective of this project was to measure the backwater and discharge distribution for multiple bridges. These data have been used to determine if the methods developed by Schneider and others (1976) for single-opening highway crossings could be applied to multiple bridges. In addition, the method developed by Tracey and Carter (1955) and Cragwall (1958) was modified to use the procedure proposed by Schneider and others (1976) to calculate friction losses in the approach reach. This modified procedure was then also tested.

Base Flow of Streams in the Outcrop Area of Southeastern Sand Aquifer: South Carolina, Georgia, Alabama, and Mississippi
From purpose and scope: The purpose of this study are to derive base flow estimates for representative parts of the Cretaceous and Tertiary clastic outcrop area as an aid in estimating recharge to the sand aquifers; to use base flow relations to estimate aquifer hydraulic parameters; and to relate the lithology of the aquifer to the streamflow duration curves.

Chemical and Hydrologic Assessment of the Caloosahatchee River Basin, Lake Okeechobee to Franklin Lock, Florida
From purpose and scope: The U.S. Geological Survey, in cooperation with Lee County, conducted an investigation of the river in 1976-79. This investigation was planned to provide a broader base if information than heretofore available on the freshwater resources of the Caloosahatchee River basin, and in particular to provide information on water-quality conditions with emphasis on nutrients and algal growth. In addition to data collected during 1976-79, some earlier data collected by the U.S. Geological Survey were included to evaluate annual variation and trends.

Debris Flow Hazard Assessment for the Oregon Caves National Monument
From introduction: Of the various hydrologic hazards in our environment, the mass movement of earth material caused by excess moisture can be one of the most destructive. These events often go unnoticed because they occur in unpopulated mountainous terrain during winter seasons. This was not the case in December 1964, when a major debris flow occurred in the Cave Creek drainage of the Oregon Caves National Monument. In March 1982, the National Park Service (NPS) requested a study be made to appraise the possibility of a recurrence of the 1964 debris flow in the interest of safeguarding the public and employees of the National Park Service.

From introduction: The purpose of this report is to test the accuracy and precision of the MIBK extract technique and its suitability for A1 determination in rain, surface waters, ground waters, and effluents obtained from leaching various types of rocks with acidified water. The present study investigates the accuracy, precision, and detection limit of this technique and reports methods for improvement. The purpose of the report also is to test the effect of filtration of water samples and the storage of samples in conventional polythylene (CPE), linear polythylene (LPE), and polypropyene (PP) bottles on accuracy of A1 determination.
