Geohydrology of the Meadowbrook Artificial-Recharge Site at East Meadow, Nassau County, New York
Purpose and scope: The Meadowbrook artificial-recharge project, a cooperative effort between the U.S. Geological Survey and the Nassau County Department of Public Works (NCDPW) since 1975, is intended to demonstrate the feasibility of using reclaimed wastewater to replenish and improve the quality of Long Island's ground water. This report presents the results of geologic, hydrologic, and hydrochemical studies that were done at the Meadowbrook artificial-recharge site to define conditions prevailing before the start of recharge operations.

U.S. Geological Survey Research in Radioactive Waste Disposal--Fiscal Year 1981
Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.

Hydrologic Effects of Annually Diverting 131,000 Acre-Feet of Water from Dillon Reservoir, Central Colorado
From abstract: because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased diversions of water from Dillon Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reservoir each year, were reconstructed by mass balance for the 1931-77 water years. Based on the analysis, the annual maximum end-of-month drawdown below the elevation at full storage would have been 171 feet.

Sediment Transport and Source Areas of Sediment and Runoff, Big Sandy River Basin, Wyoming
Abstract: A study was conducted for the resolution of sediment source areas in the Big Sandy River basin, southwestern Wyoming. Suspended-sediment and bedload data were collected in order to determine total sediment transport at several locations within the basin. The bedload data were compared to the Einstein bedload function and total load data were compared to the Colby method. The bedload comparison showed a higher estimation of transport rates with Helley-Smith sampler measurements than with the Einstein beadload function. The Colby method yielded higher transport rates at high flows and lower transport rates at low flows than the measured total transport rate. The Big Sandy reservoir acts as a control in the basin. The area upstream of the reservoir was interpreted separately from the area downstream for source-area determination. In the arid plains upstream of the reservoir, the amount of sediment transported increased 98 percent with an increase in runoff of only 1 percent.

Hydraulic Considerations in Sampling the Unsaturated Zone with Inclined Gravity Lysimeters
Purpose and scope: This report discusses the design, theory of operation, performance characteristics, and sampling implications if the inclined gravity lysimeter. This variation of a gravity lysimeter can be constructed to maximize capture efficiency and eliminate artificial filtration and is used most successfully in coarse, moist soils where access for installation is from a trench or observation manhole.

Physical and Hydrologic Environments of the Mulberry Coal Reserves in Eastern Kansas
From introduction: The U.S. Geological Survey is currently conducting a two-phase investigation designed to provide hydrologic information about the coal-producing area in Miami, Linn, and Bourbon Counties of eastern Kansas (fig. 1). This report presents information to satisfy the objectives of the first phase of the investigation. These objectives are to: (1) assemble and interpret existing hydrologic data; (2) describe the physical and hydrologic environments based on existing data; and (3) determine additional data needed to evaluate the impacts of coal mining on the hydrology of the study area.

Map Showing Altitude of the Top of the Lakota Formation and Equivalent Rocks, Montana
Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the altitude of the top of the Lakota Formation and equivalent rocks. Other maps show the total thickness (Feltis, 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Lakota Formation and equivalent rocks. These maps are part of a series that describes the geology and potentiometric surface of selected rock units of Jurassic or younger age in the plains area of Montana.

Flow Routing in the Susquehanna River Basin: Part III -- Routing Reservoir Releases in the Tioga and Chemung Rivers System, Pennsylvania and New York
From abstract: Channel-routing models were used to route hypothetical releases from reservoirs in the upper Tioga River basin, Pennsylvania. These releases were routed northward down the Tioga River to Lindley, Erwins, and Corning, New York; combined with flows routed down the Cohocton River from Campbell to Corning, New York; and then routed southeastward down the Chemung River from Corning to Chemung, New York. The models used to route the flows of Cohocton and Chemung Rivers accounted for bank-storage discharge and streamflow depletion by well pumpage. In general, 17 years of concurrent streamflow data were available for model calibration and verification.
