Conjunctive Use of Surface and Groundwater Resources in the Central Valley of California
California Department of Water Resources (DWR) is evaluating the feasibility of incorporating a conjunctive use program into the State Water Project (SWP) to augment its delivery capability...

Harvest of Ephemeral Runoff for Artificial Groundwater Recharge in Arid Basin Water Management
Harvest of springtime flow to a playa in Lemmon Valley, north of Reno, was evaluated as a means of increasing local groundwater supplies through artificial recharge. Surface water and...

Groundwater Depletion and Salinity in Yazd, Iran
The central Iranian plateau contains part or all of five provinces and covers more than a third of the total area of Iran (Figure 3). This area has one of the most unfavorable hydrologic...

Structural Control of Ground-Water Induced Debris Flows
A number of case studies have attributed debris flow initiation to the effect of elevated pore pressure from a bedrock ground-water source. Debris flows on slopes underlain by Precambrian...

Water Quality Study in an Arid Region Lake: Lake Bosten, Northwest China
This paper gives a brief description of Lake Bosten, its importance to Xinjiang Province of the PRC, objectives of an on-going study, and some preliminary results. This on-going study...

Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment
The Task Committee on Transport Processes at the Interface of Water Column and Bottom Sediment was formed on October 1, 1989 under the Technical Committee on Hydrologic Transport and Dispersion...

A Review of the State-of-the-Art in Sediment-Water Column Interaction Measurement Techniques
This paper reviews the state-of-the-art measurement techniques available to water quality modeling practioners to estimate: (a) sediment oxygen demand rates, (b) sediment-water column...

Water Supply and Aeration Demands for Shrimp Farms
A computer model was developed simulating flow and aeration requirements for a range of farm sizes, from 50 to 2000 hectares. Climatic effects and water quality upset conditions were included...

Shop Creek Stormwater Quality Enhancement Project
The advent of NPDES regulations for stormwater discharges creates a need to verify, on a regional basis, the effectiveness of emerging water-quality control technologies such as extended...

CORMIX2: Expert System for Multiport Diffuser Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software systems for the analysis, prediction, and design of aqueous toxic or conventional pollutant discharges into watercourses,...

An Expert Advisor for Selective Withdrawal Operations
A rule-based computational advisor that aids in the selection of selective withdrawal operations for project release temperature maintenance is discussed. This advisor couples a one-dimensional...

Physical Forces Generated by Barge-Tow Traffic Within a Navigable Waterway
Movement of navigation traffic such as barge tows within a restricted inland waterway such as the Illinois, Mississippi, or Ohio Rivers can and will alter the flow field in and around...

Storm Water Management and Wetland Restoration?Ballona Channel Wetlands
A storm water management plan was engineered to provide storm water dention necessary for site develop and at the same time to allow wetland restoration. Objectives of the project were:...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

Measurement of Hydraulic and Environmental Effects of Aeration Devices in Douglas Reservoir
The releases from Douglas Reservoir experience periods of low dissolved oxygen (DO) content during the summer months. Tests were conducted during August 1989 to determine the effects of...

Sacramento's Proactive Stormwater Permit Program
In January 1990, with the encouragement and assistance of the California Regional Water Quality Control Board-Central Valley Region (Regional Board), the City and County of Sacramento,...

A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...

Long-Term Numerical Simulation of Three-Dimensional Hydrodynamics of Chesapeake Bay
A time-varying 3D numerical model of Chesapeake Bay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and...
