Leaching Characteristics of Metal Finishing Sludges
The purpose of this research was to study the feasibility of biodegrading phenolics to methane by thermophilic anaerobic treatment. The study was a feasibility level assessment which examined...
Engineering Methodology for Delineating Debris Flow Hazards in Los Angeles County
Utilizing historical and field data, elementary geomorphology and simplified hydraulics of debris flows, a mapping strategy has been developed. The delineation procedure includes defining...
National Perspectives and Policy on Nonpoint Sources of Water Pollution
The paper presents the perspective of the Environmental Protection Agency (EPA) on the title subject. It makes the point that while EPA continues to implement the major point source efforts...
Flood Risk Below Steep Mountain Slopes
Alluvial fans spread at approximately the critical hydraulic slope below apexes at canyon mouths. Periodic torrents that rage out of the canyons are devastating at the apex and have diminishing...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
Small Hydro is Very Rarely Typical
Engineering design of a small hydro project is often considered to be straightforward. Many potential developers assume that the engineering effort can be reduced to 'typical'...
An Evaluation of Sediment Resuspension Parameterizations
The recent attention to managing surface water toxic substances has resulted in a number of modeling approaches, all of which to a great or lesser extent require accurate treatment of...
Performance of a Deterministic Storm Runoff Model
The paper discusses model comparisons based on a Tulsa, Oklahoma, case study. Modeling strategies were explored, four of which were modeled in detail because of the extremes in range of...
Water Infrastructure Maintenance Needs?A Case Study
Adoption of measures to prevent loss of water in many cases is cost-effective. In order to illustrate the magnitude of infrastructure problems of large cities, a test case infrastructure...
Remedial Action Alternatives for Groundwater Contamination
Preliminary remedial action alternatives are formulated for a site contaminated by heavy metals. The results of soils and hydrogeologic investigations are summarized and three corrective...
On the Ship's Waterways Passing Through Bridges
This paper reports on a study of bridge openings that serve as waterways, in view of the analysis of ship collision accidents. For the purpose of this study, cases of ship collision accidents...
Port Infrastructure Program in Mexico
In Mexico the policies, guidelines, goals and methodologies refering to transport, are the responsibility of the 'Secretaria de Comunicaciones y Transportes'...
Reservoir Sedimentation and Desilting in Taiwan
The island of Taiwan is infested with numerous flashy streams with steep slopes and huge sediment loads, thus, the major reservoirs have experienced heavy sediment deposit. The encroachment...
A Proposed Desilting Reservoir System in Taiwan
The paper discusses the design of a desilting system for Nanhwa reservoir, in which the reservoir is divided into two bays; water flows into the forebay for sedimentation and then over...
Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...
Routing Comparisons in Natural and Geometric Channels
A method of establishing composite geometric cross section shapes hydraulically similar to natural cross sections with flood plains is proposed. The method is based on the nondimensionalized...
Estimating Probable Storm Damage on Barrier Islands
This paper demonstrates a methodology for estimating probable property damage losses from hurricanes on barrier islands. Using the case study of Gasparilla Island, Florida, it estimates...
Sedimentation Processes in Hydrosystems, Numerical-Empirical Modeling
This paper presents the results of a newly developed computer simulation model for studying the sedimentation processes in a variety of hydrosystems. The most effective numerical methodology...
Sedimentation in the All-American Canal
During the planning for the All-American Canal, by the U. S. Bureau of Reclamation as part of the Boulder Canyon Project, works were designed at the head of the canal to remove between...
Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...
