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;...

Capillary Pressure-Saturation Relationships in Fracture
Understanding and quantifying unsaturated flow through fractures in rocky slope is important for design and construction of drainage system in large-scale hydraulic engineering. The data...

Scour at Culvert Outlets: Considerations Present and Future
One of the major considerations in the design and rehabilitation of the national transportation system is the conveyance of tributary drainage through constructed embankments. As drainage...

The purpose of this paper is to present an overview of the efforts by Snohomish County to acquire a drainage district (Drainage District 6) in the lower Snohomish River valley and restore...

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,...

Storm Drainage GIS, Modeling, and Master Planning for the City of Berkeley
The City of Berkeley has completed its Storm Sewer Master Plan. The master plan com bined the findings of field inspection worig computer-based mapping, and geographic information system...

Hollyhills Drain Relief for 1920s Drainage System
The paper will discuss design and construction problems encountered for a $50,000,000 Urban Storm Drain System in the Metropolitan Los Angeles Area. The Drainage System relieves a system...

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...

Artificial Recharge of Ground Water II
The Second International Symposium on Artificial Recharge of Ground Water was held in Orlando, Florida from July 17-22, 1995 and sponsored by the ASCE Special Standards Division, the ASCE...

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...
