Water Use Recession in San Diego Region
Water use in the San Diego region was studied using historical records collected over a period of a half century. The results indicated that the water use in this region was historically...

A Practical Approach to Watershed Sanitary Surveys
A step-by-step approach for conducting watershed sanitary surveys can be successfully applied to watersheds of all sizes. The approach involves preparing a watershed map, contacting regulatory...

Wastewater Reuse: An Alternative for Potable Water
Adverse economic conditions throughout the world have resulted in a shift of priorities causing water supply and sanitation schemes to relegate down the list of adequately funded projects....

Measurements of Bridge-Scour Depths in Mississippi
This paper briefly summarizes 190 measured pier-scour depths collected dur ing 1942?94 at 22 selected bridges in Mississippi and presents an envelope-curve equation for the data. The envelope-curve...

Field Measurements of Streambed Scour at Bridge Piers in Ohio
Field measurements made from 1989 to 1994 were evaluated to characterize pier scour at 21 bridge sites in Ohio. Pier scour was observed at sites in 45 of 47 real-time scour measurements....

Scour-Hole Dimensions at Selected Bridge Piers in New York
Knowledge of scour-hole dimensions can be used by bridge engineers to deter mine the extent of countermeasures needed to prevent scour at bridge piers. Scour-hole widths at 128 piers,...

Sacramento Valley Conjunctive Use?Future Water Supply for the State Water Project?
In 1992, the California Department of Water Resources began an investigation of the potential to develop additional water supply for the State Water Project through conjunctive use programs...

A New Model of California's SWP/CVP Systems
A water allocation reservoir simulation model is combined with a ground water-surface water simulation model resulting in an integrated model for use in water resource planning studies...

Implementing a Successful Conjunctive Use Program
Over the past decade, water planners have come to the agreement that conjunctive use is a good strategy to help meet present and ftiture water needs. Storing water underground has many...

Design Guidelines for Bioengineered Bank Stabilization
Design of bioengineered slope stabilization measures in riverine environments to minimize rates of stream bank erosion requires accounting for hydrologic, hydraulic, geomorphic, geotechnical,...

River Restoration Considerations Beyond Channel Design
Restoration of river systems in highly disturbed environments poses unique challenges beyond channel design. The Jordan Creek Restoration project in Idaho was conducted in a valley disturbed...

Immobilization of Metals and Solids Transported in Urban Pavement Runoff
Urban areas in North America continue to grow in size and population. With this growth is an increase in automotive traffic, roadway pavement and deleterious anthropogenic constituents....

Protecting Dredged Material Containment Levees along the Houston Ship Channel
This paper describes the background, selection, installation, and performance of the three-dimensional woven geotextile used for erosion protection along 122 meters (400 feet) of levee...

Navigation Lock Improvements
All commercial barge traffic on the Upper Mississippi River and Illinois Waterway must pass through a system of locks designed and built in the 1930s and 40s. Many of the locks on these...

McAlpine Intake Model Study for Innovative Lock Design
The McAlpine Locks and Dam Project is located on the Ohio River near Louisville Kentucky. Construction of an additional 33.53-m-wide (110 ft) by 365.76-m-long (1200 ft) navigation lock...

Lake Number: A Long-Term Lake Water Quality Predictor
A seasonal maximum Lake number was found to be a good predictor for volume averaged water temperatures, maximum water temperatures near lake bottom, seasonal stratification characteristics,...

Results of a GIS/HEC-1 Interface Module
Great strives have been made in recent years to automate the S.C.S. curve number weighting process required for large-scale watershed modeling utilizing Geographic Information System (GIS)...

Modeling of Rattlesnake Creek Watershed Using Swat Model
Watershed scale models are widely used in design and operation of river basin projects and for guiding public decisions. This paper presents modeling details of Rattlesnake Creek watershed...

Changes in Ground Water?Surface Water Interaction in the Santa Ana River Caused by Independent Water Resources Management Activities
For the past 18 years, ground water artificially-stored in the Chino Basin, has been managed as a zero-interest bank account. Recent water resources management studies show that losses...

Upper Mississippi River System Environmental Management Program (EMP)
Introduction The Upper Mississippi River Navigation System (UMRNS) is one of the largest Public Works projects existing within the continental United States of America. The system, which...
