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...

Marginal Cost Techniques for Reservoir Optimization
Selection of the optimum water supply reservoir from multiple reservoir sites under consideration in a water resource planning study for the Houston Metroplex evaluated hydrology, engineering,...

A Comparison of Two Reservoir Projects and Associated Fisheries Impacts
The evaluation of environmental impacts is a critical component of reservoir project development. Impacts to fisheries are especially significant because of the extensive alteration to...

Study of Direct Potable Reuse of Reclaimed Wastewater: Preliminary Results of a Five Year Study
The City of San Diego, California has received Clean Water Grant funding to build and operate a 0.5 million gallon per day facility to demonstrate a wastewater treatment system, utilizing...

Hueco Bolson Recharge Demonstration Project
The Hueco Bolson Recharge Project in El Paso, Texas, is a unique recharge system, being a full-scale program in operation for 5 years in which municipal sewage is treated to potable quality...

Conjunctive Management of the Edwards Aquifer and Connected Surface Streams in South Central Texas
The Edwards Aquifer is a long, narrow conduit through which water moves underground across parts of South Central Texas. Increased use of water from the Edwards Aquifer has been substantial...

Managing an Interruptible Water Supply
The Lower Colorado River Authority has developed a plan for the management of an interruptible water supply for demands which do not require a firm commitment of specific amounts of water....

Corps of Engineers Drought Contingency Plans in Texas
The Corps of Engineers, Fort Worth District, is currently preparing Drought Contingency Plans (DCP) for the river basins and its projects. These plans will be incorporated into the master...

Benefits from Floodplain Management Activities in Relation to Operating South Holston Dam
Floodplain management activities have primarily been directed toward avoiding floodplain siting where practical; where siting is unavoidable, elevating structures, facilities, or equipment...
