Eastern San Joaquin County Groundwater Resource Planning Alternative Analysis
An Integrated Groundwater and Surface Water Model (IGSM) has been developed and calibrated for eastern San Joaquin County in the Central Valley of California to evaluate future water resources...

The Direction of the Point Source Program
The NPDES permit programs operate under the concept of providing for a cleaner environment by restricting the release of pollutants. Over 500,000 sources are now subject to regulation...

The Effects of Water Surface Profiles on Manning's Roughness Coefficient
The Manning Equation has wide application in engineering practice. Nonetheless, certain aspects of it are still not widely understood. Often, engineers deduce the value of Manning's...

Evaluating Hydraulic Roughness in Tunnels
Much of the data presented in the literature on measured friction losses in tunnels are given in terms of the Darcy-Weisbach f or Manning's...

Contraction Scour at Bridges: Analytic Model for Coarse-Bed Channels
Contraction scour at bridges spanning coarse-bed channels is evaluated based on mass conservation of both water and transported sediment between a reference channel section near the crossing...

The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...

Los Angeles County Department of Public Works Storm Water Quality Assessments, Los Angeles, California
This study included a general assessment of the surface water quality conditions within the Los Angeles County area by examination of the surface water quality data collected by LACDPW...

Water Resources Planning for the Fort Peck Indian Reservation, Montana
Water resources planning in Indian Country has produced varied results. On the Fort Peck Indian Reservation, the Assiniboine and Sioux Tribes are using an integrated approach to managing...

Stochastic Determination of Wave Heights for Flood Control Channels
Physical model data for subcritical and supercritical flow has been collected and analyzed to determine a statistically-based relationship for wave runup heights in a trapezoidal channel....

A Knowledge Based System for the Design of Open Channels
The design of open channel facilities often calls for evaluation of a unique set of physical conditions which do not lend themselves to standard designs and textbook solutions. Consequently,...

Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...

When Toxics Meet Metal
Zero-valent iron is an emerging remediation technology that transforms chlorinated solvents to harmless substances. Engineers and researchers have been studying the process for about five...

19 Tough Acts to Follow
The nominations for this year's Outstanding Civil Engineering Achievement Award included everything from runway extensions to highway extensions, water fun parks to water...

Case Histories of Geophysics Applied to Civil Engineering and Public Policy
These case histories will be of interest to both civil engineers and geophysicists. They document the use of a variety of geophysical methods in support of civil engineering projects....

Roads and Airfields in Cold Regions
This state-of-the-practice report on the design and development of roads and airfields is the eighth monograph in a series prepared by the Technical Council on Cold Regions Engineering...

Guidelines for Field Evaluations of Pothole Repairs
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes the HITEC evaluation plan for Bondade,...

Specifying End Results
Quality of materials and workmanship directly influences the life of pavement, maintenance costs, levels of service and user costs. End result specifications (ERS) make a step towards...

Tracking a Serial Filter
The Humboldt Bay Municipal Water District in northern California conducted pilot testing of extreme/high-rate serial filtration (EHRSF) to see if the process could meet water treatment...
