Some Hydrological Impacts of Climate Change for the Delaware River Basin
To gain insight into possible impacts of climate change on water availability in the Delaware River, two models are linked. The first model is a monthly water balance model that converts...

Predicting Effects of Global Climate Change on Reservoir Water Quality and Fish Habitat
This paper demonstrates the use of general circulation models (GCMs) for assessing global climate change effects on reservoir water quality and illustrates that general conclusions about...

Non-Point Source Contamination of Aquifers
The paper discusses a new method for simulating the movement of contaminants from a diffuse source at the soil surface through a variably-saturated porous medium. The method accounts for...

Modeling Groundwater Flow in San Joaquin Valley
Water supply, reallocation and conjunctive use options, within the San Joaquin and Tulare basins of the Central Valley of California, are being considered by Federal and State Planning...

Groundwater Modeling of the Tustin/Irvine Basin
This paper describes the results of groundwater modeling in the Tustin/Irvine basin situated in the southeastern portion of the Tustin plain, which is the the southern extension of the...

Spatial Averaging of Statistically Anisotropic Point Conductivities
This paper presents a new technique to compute the mean, variogram and cross-variograms of the components of block conductivity tensors given the statistical distribution of point conductivities....

Design of Sampling Networks for Water Table Monitoring
In the application to the monitoring of water tables the presence of temporal and spatial dependence is of crucial importance. Often the network will be used to collect data to estimate...

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)...

Advances in Hydraulic Stream Modeling Using HEC-2
The Corps of Engineers, Ft. Worth, Texas, Flood Plain Management Services Branch has developed hydraulic stream models for creeks and rivers throughout the state of Texas for the purpose...

Montgomery Point Lock and Dam Entrance to the McClellan-Kerr Arkansas River Navigation System
The McClellan-Kerr Arkansas River Navigation System has experienced a steady and positive increase in use. However, in the last 10 years changing conditions along the Mississippi River...

Instream Habitat Considering Hydro-Peaking
Hydroelectric projects with storage have the characteristic of being able to generate electricity with short notice and to stop generating electricity with equally short notice. This peaking...

Application of the GRASS Geographic Information System in a Sensitive Environment of the Arkansas River Navigation System
A Geographic Information System (GIS) was used to assist the selection of environmentally sensitive dredge material disposal sites along the Arkansas River Navigation System. Maintenance...

Identification of Aquifer Parameters in Confined Groundwater Flow
The logarithm of the aquifer properties, log transmissivity (log T) and log storativity (log S), are regarded as realizations of stochastic processes whose estimates are required. The...

Optimization of a Groundwater Well Monitoring Network
An optimization model is presented for the design of a well monitoring network for groundwater quality and quantity parameters. The model utilizes a geostatistical procedure to estimate...

Modeling Volatile Organic Transport with Vapor Sorption
A flexible finite element simulation model is developed to predict the movement of volatile organic compounds in variably saturated subsurface regions. The model incorporates both the...

Groundwater Quality Network Design
This paper presents a methodology that uses optimization for designing a groundwater monitoring network. The methodology incorporates parameter estimation in conjunction with a numerical...

An Economic Evaluation of Property Rights to Groundwater Resources in the State of Texas
The objective of this paper is to evaluate the basis for determination of property rights to groundwater in Texas, and to consider the implications of existing groundwater legislation...

A Newsboy Approach to Real-Time Reservoir Operation Modelling
This investigation focuses on the use of mathematical programming techniques to develop a model for scheduling, in real-time, the releases from a single reservoir via a probabilistic approach...

Applications of Probability Matrix Methods for Texas Reservoirs
Probability matrix methods are a class of procedures which were generally developed from P.A.P. Moran's Theory of Storage. In essence, probability matrix methods are a means...
