Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...

Comparison Between the Field and Laboratory Measured Properties of a Clay Liner
Hydraulic conductivity (K) and bulk density (BD) of an experimental clay linear were evaluated at a large number of locations using standard methods. They were then compared to laboratory...

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...

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...

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...

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...

Streamflow Prediction and Allocation Model in Texas
The State of Texas' Water Rights Adjudication Act of 1967 provided for the creation of regional watermasters to divide the water of state streams in accordance with the adjudicated...

Numerical Model Study of Groundwater Movement in an Aquifer of Bangladesh
Annual groundwater level variation in the aquifer of the Mymensingh-Tangail area of Bangladesh was simulated by applying an implicit finite-difference model of groundwater flow. The groundwater...

Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...

Optimization of Freshwater Inflow to Estuaries
This paper presents a methodology that can be used for determining the optimal freshwater inflows into bays and estuaries for the purpose of balancing freshwater demands with the harvest...

The Center for Advanced Decision Support for Water and Environmental Systems
In July of 1988, the US Bureau of Reclamation awarded the University of Colorado a 4 year, 4 million dollar Cooperative Agreement for the development of a Center of Excellence in the Application...

Managing the Introduction of New Technologies: An A1 Case Study
The way in which a new process or product is introduced into an organization can be critical to its acceptance and successful implementation. Even if the innovation is a major technical...

Creating a Transportation Microcomputer User's Group in Mid-Michigan: Organizational Issues and Opportunities
This paper describes the Mid-Michigan Transportation Microcomputer User's Group. Purposes of the User's Group include promoting demonstrations and evaluations...

How Microcomputer Transportation Networks Can Shift Institutional Relationships Between Governmental Agencies
This paper describes the current institutional and microcomputer relationships in the Portland, Oregon metropolitan region; identifies how emerging microcomputer linkages have affected...

Local Area Networks, a Hardware and Software Tutorial
The ability to develop, access and manage information has become a strategic component of a competitive and productive office. The capability to connect groups of microcomputers is now...

Electronic Communication and Data Transfer: Productivity Enhancements
Large ventures operating from widely separated sites cannot depend on local area networks for their communication requirements, as can small, single-sited projects. Not all projects have...

PC-Graphic Scheduling in a Multi-User Environment
