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...

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...

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,...

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...

Microtunneling Meets Mother Nature
The world's first ocean thermal energy plant is getting a double. Microtunneling the second ocean intake 80 ft under the Pacific Ocean is proving challenging, partly due to...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...

A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....

A Multi-Dimensional Transport Model Utilizing a Characteristic-Galerkin Approach
A multi-dimensional transport model based on the RMA series of finite element models has been developed utilizing a characteristic-Galerkin approach. This paper examines the application...
