Transport of Injected Produced Water: A Sensitivity Study
This paper deals with the development and application of a model to assess potential environmental effects on Underground Sources of Drinking Water (USDW) due to the presence of an improperly...

Methodologies to Estimate Instream Benefits for Use in Water Allocation
In the 'utility valuation' approach, the recreational experience possible at given flow levels is examined to derive a utility that the resource provides to the...

Generation of Multiple Tier Instream Flow Requirements
Multiple tier scaling of instream flow requirements based on available water supply and reservoir storage state is proposed as a means of generating instream flow regimes. Rules for variable...

Water Quality Criteria for Irrigation
An assessment of irrigation water quality for the concentration of inorganic constituents should consider crop sensitivities, soil properties, such as hydraulic conductivity, reactions...

In Situ Measurement of Preferential Flow
An experiment was performed that quantifies the variability of flow paths in the vadoze zone. Bromide tracer and an organic dye, which has many of the same transport characteristics as...

Economic Impacts of Storm Sewer Design Criteria
This paper discusses the selection of storm sewer design criteria and the resulting economic impacts. Using the Rational Method for calculating design flows, an investigation was made...

Modeling of Nitrate Transport Coupled Dentrification in the Saturated Zone
A numerical model for simulating nitrate transport coupled to microbial activity in the saturated zone is presented. A coupled system of equations describes the transport and microbial...

An Interactive Microcomputer Program for One-Dimensional Solute Transport in Saturated Soil-Water Systems
This paper presents a user-friendly microcomputer program for one-dimensional solute transport in saturated soil-water systems. Eight different types of adsorption isotherms, ranging from...

Response of a Surface Aquifer to Flood Irrigation
The response of an unconfined alluvial aquifer, and associated stream system, to recharge by flood irrigation in the New Fork River valley in western Wyoming was studied. A water budget...

Aquatic Weed Control by Grass Carp in Cool Water
Diploid grass carp have significantly controlled problem aquatic vegetation during a 3-year study in a northern Colorado irrigation canal where water temperatures ranged from 0 to 25?C....

Water Erosion Prediction Project Operational Computer Program
The Water Erosion Prediction Project (WEPP) is a physically-based model to improve on-site erosion prediction techniques. It is designed to replace the Universal Soil Loss Equation (USLE)...

Managing Water Table Management Systems for Water Quality
The purpose of this paper is to briefly summarize the results of water quality studies related to water table management conducted in North Carolina over the past 15 years. Results of...

Proper Use of Effective Flow Boundaries
The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with...

Estimating Impacts of Irrigation on Streamflow
This paper presents a method for estimating the impact of irrigation withdrawals on streamflows and shows the application of that method to the Kankakee River Basin of Illinois and Indiana....

Hydrologic Criteria: NPS Water Quality Assessment
This paper summarizes the authors deliberations and findings regarding selection of hydrologic conditions suitable for the evaluation of the water quality impacts of nonpoint sources (NPSs)...

Computer Control of Water Systems: Practical Considerations
Presented are some applications projects and procedures concerned with modeling and control of water supply and distribution systems. The work has resulted in the development of a suite...

Dynamic Modeling and Control Optimization in An Urban Area?A Case Study
The procedures adopted to achieve improved economic operation of the water supply and distribution system serving the town of Wolverhampton (UK) are described. An outline description is...

The Alabama Rainfall-Runoff Model, ARRM
ARRM consists of a conceptual state-space model which is cast in a stochastic framework. It uses the W.H. Green and C.A. Ampt method for infiltration, exponential decay for interflow and...

What is Necessary to Forecast River Flows Reliably?
The problem of forecasting river flows employing conceptual rainfall-runoff models is reviewed stressing the important connections that exist among data requirements, model structure,...

Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....
