Graphical Method for Estimating Occurence and Duration of a Critical Low Flow in the Sacramento River at Freeport, California
Abstract: Sacramento County expected to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or less. Depending on tide condition, flows less than 4,000 cubic feet per second may occur either once or twice during each 24-hour 50-minute tide cycle when the daily mean flow is less than about 12,000 cubic feet per second. Daily mean flows less than 12,000 cubic feet per second occur about 28 percent of the time. Riverflow at the plant outfall is monitored by an acoustic streamflow measuring system. Regulation of effluent released from the plant will normally be based on real-time flow data computed by the acoustic system. A graphical method for determining the occurrence and duration of flows of 4,000 cubic feet per second and less was developed as a backup system to be used if a temporary failure in the acoustic system occurs.

Reconnaissance of Ground-Water Quality, Eastern Snake River Basin, Idaho
From purposes of approach of study: The purposes of this study were to: (1) Define, on a reconnaissance level, current (1979) water-quality conditions in major aquifers (water-yielding rock formations) in the eastern Snake River basin; (2) present available geologic and hydrologic data to assist in understanding the natural and man-caused factors that affect water-quality conditions; and (3) establish a hydrologic base upon which future comparisons can be made to evaluate changes.

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.

Hydrogeology of a Landfill, Pinellas County, Florida
Abstract: The Pinellas County landfill site is on a flat, coastal area characterized by a nearsurface water table. Part of the site is subject to tidal flooding; altitudes within the study area range from 8 to 12 feet above sea level. Three geohydrologic units underlie the landfill site. In descending order, these are: a surficial aquifer about 19 feet thick composed of sand and shell, a confining bed about 35 feet thick composed of marl and clay, and the Floridan aquifer composed of limestone. Landfill operations have not altered surface-water quality. Although leachate movement downward into the Floridan _aquifer is not indicated, vertical movement through the confining bed is about 0.005 foot per year. The rate of lateral movement of ground-water away from the site is about 1.2 feet per year; . however, the rate of movement along the boundary from the oldest section of the landfill through the surficial aquifer is about 20 feet per year. Peaks in concentration of selected chemical parameters and flow-rate analysis of water from trenches indicate the possibility of intermittent release of leachate from the landfill.

Reservoir Development Impacts on Surface-Water Quantity and Quality in the Yampa River Basin, Colorado and Wyoming
From introduction: This report describes the results of an investigation in which three computer models were used to evaluate different levels of the proposed reservoir development. One model simulated streamflow conditions with alternative multireservoir configurations; a second model simulated the dissolved-solids concentrations at various locations in the basin; and a third model used streamflows and dissolved solids concentrations to simulate the water-quality conditions within certain proposed reservoirs. This study was designed to demonstrate the application of computer-modeling techniques in evaluating impacts of proposed reservoirs.
