Seepage and Transport through Anaerobic Lagoon Liners
In this chapter, the seepage and transport characteristics of lagoon liners are addressed using the soils and hydrogeology of southwest Kansas as examples....
Simulation of Regional Ground-Water Flow on a Transboundary Flowline; Trans-Pecos, Texas and Chihuahua, Mexico
A two-dimensional, steady-state, cross-sectional model was used to evaluate boundary conditions, residence times, and potential transboundary movement along a 28 mi (45 km) flowline between...
Characterizing the Hydrogeologic Framework of the Death Valley Region, Southern Nevada and California
Three-dimensional (3-D) hydrogeologic modeling of the complex geology of the Death Valley region requires the application of a number of Geoscientific Information System (GSIS) techniques....
Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Source Term Model for Radioactive Waste Repository
A radioactive waste repository source term model is developed to predict radionuclide release rates from solidified waste packages disposed of in underground repository. Leach rates, i.e.,...
Low Flow Index and Hydrogeological Characteristics
This work is set within a framework of research on drought phenomena, causes and effects, and the methods to fight the harmful effects of droughts in the agricultural, municipal and industrial...
Analysis of Uncertainty in Ground-Water Quality Monitoring Network Design
The paper reviews alternative approaches to ground-water quality monitoring network design. Four general approaches to network design are reviewed: (1) hydrogeologic, (2) simulation, (3)...
Hydrogeologic Factors Affecting Trace Element Mobility
Alluvial deposits often comprise the aquifer beneath irrigated lands in the southwestern U.S. The presence of buried stream channels in, and layering of, shallow alluvial deposits are...
Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...
Low-Level Waste Disposal Design: An Overview
Low-Level radioactive waste disposal is regulated by several agencies. Mixed waste, which is both radioactive and chemically hazardous is regulated by two agencies with potentially different...
Reclamation's Recharge Projects: California-Nevada
Under the High Plains States Groundwater Demonstration Program, the Bureau of Reclamation has recommended construction of 21 projects in 17 western states. The projects contain technical...
Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...
Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...
Groundwater Vulnerability to Contamination: A Literature Review
Methods are needed to allow regulatory agencies and resource managers to predict, from readily available data, the potential for groundwater contamination problems. Regional maps developed...
The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....
Ground-Water Flow Model of Soda-Ash Waste Beds
A recent application by a steel manufacturing plant to obtain a permit for an industrial landfill located on top of abandoned soda-ash waste beds in the City of Syracuse, New York, resulted...
The National Water Well Association's Ground Water Software Centre
The National Water Well Association (NWWA) offers a new service to the members of the ground water industry. NWWA's Ground Water Software Centre markets computer programs...
Hydrogeologic Controls on Leachate Migration
The Brown Station Road Landfill is a municipal solid waste disposal site operated by Prince George's County, Maryland. The work described herein was conducted as part of a...
