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....
Development of Islandwide Groundwater Pollution Potential for Taiwan
Using the modified DRASTIC and existing and newly surveyed data, groundwater pollution potentials for all 10 groundwater basins in Taiwan were calculated on 2 km by 2 km grids. This paper...
Influence of Flooding Events on Suspended Matter Quality of the Meuse River (The Netherlands)
Flooding events of the Rhine and Meuse Rivers have struck The Netherlands in 1993 and 1995. In the Meuse River basin, the river forelands have been widely used for housing and agro-industrial...

River Dnister has a length of 1,352 km. Its spring is situated in Carpathian Mountains at the height of more than 900 m. Dnister runs across the territory of Ukraine and Moldova Republic...
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...
GIS Applications in Modern Stormwater Management
A Geographic Information System (GIS) is a technology that aids stormwater management through efficient data manipulation, analyses, and graphic displays. The integration of GIS with stormwater...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...
On Silt Abrasion Erosion of Three Gorges Hydraulic Turbine in the Future
In this paper the basic parameters of Three Gorges hydraulic turbine have been reviewed and the operation characteristics of Three Gorges hydropower Station pointed out. Combined with...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
A Decision Making Approach for Stormwater Management Measures?A Case Example in the City of Waukesha, Wisconsin
An urban nonpoint source pollution predictive model (Source Load and Management Model?SLAMM; Wisconsin Department of Natural Resources, 1990), and a decision matrix developed specifically...
Calibration of a Water Quality Model Using the Influence Coefficient Algorithm
A methodology based on the influence coefficient algorithm was established for the calibration of QUAL2E reaction coefficients. It was applied to the stream sections of the South Han River...
The Mamala Bay Study, Oahu, Hawaii: Introduction
A comprehensive multi-disciplinary study was conducted to evaluate the effects of point and non-point source discharges on the water quality of Mamala Bay, Oahu, Hawaii. The investigation...
Laboratory Evaluation of a Conductivity Probe for Scour Monitoring
Laboratory tests were used to evaluate the ability of conductivity sensors to measure streambed elevation. Tests were completed on a 2.1-m probe with a resolution of about 8 cm that was...
Bank Protection Toe-Downs and Local Pier Scour
The zone-of-influence for pier scour may impact bank protection toe-down depths. Countermeasures were required at a site along the Salt River in Phoenix, Arizona when the alignment of...
Lake/Reservoir Restoration Activities in Taiwan
The paper presents a brief overview of recent lake and reservoir restoration project activities in Taiwan, an island nation in a sub-tropical and relatively wet climate. Because of steep...
Effect of Reservoir Hedging on Crop Yield Under Deficit Irrigation Conditions
In case of irrigation projects, irrigation scheduling at the field has a direct bearing on yield crops. Hence, the various reservoir operating policies considered have to be evaluated...
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...
Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...
Seawater Intrusion Solutions for the Salinas Valley
Seawater intrusion has been occurring in the aquifers of the Salinas Valley ground water basin for more than 40 years. Two capital projects that will help reduce the rate of seawater intrusion...
