Impact of Point and Nonpoint Discharges on the Water Quality of a Reach of the Red River of the North
Projected increase of discharge of point and nonpoint-source effluents into rivers, make compliance with water quality standards increasingly difficult and necessitate controlling these...

Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...

CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....

The Timberlake Dam Failure: A Hydrometeorological Assessment
Extremely heavy rainfall over the Timberlake basin in southwest Virginia on 23 June 1995 caused an earthen dam to fail and resulted in fatalities. The meteorological conditions are examined...

COASTMAP: An Integrated System for Environmental Monitoring, Modeling and Management
The development of COASTMAP, an integrated system for environmental monitoring, modeling and management for fresh and marine waters, is presented. The system allows the user to collect,...

Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...

Experiences in Cleaning Up the Influence of Oil Spill on the Water Bodies
Experiences in cleaning up the influence of oil spill on water bodies of Komi Republic (European part of Russian North) and Dagestan Republic (North Caucasus) was generalized. In both...

Runoff Forecasting Using a Local Approximation Method
Forecasting of hydrological events, particularly floods, is an important topic of concern for hydrologists. Flood hazards can be prevented or their effects minimized if prior warning of...

Bacterial and Chemical Pollution of Littoral Waters of Lake Ohrid at Pogradec?Town Area
The Pogradec shore waters exceed these bacteriological standards and provide risks to the public health. The levels of the chemical indexes clearly show the influence of organic pollution....

The 1995 Flood in Southeastern Norway?Operational Forecasting, Warning, and Monitoring of a 200-Year Flood
The southeastern part of Norway experienced during the 1995 spring the highest flood recorded since the devastating flood in July 1789. The snow storage was at the end of April 30 to 50...

The Largest Water Reservoirs of Russia in Flood Control
(Asbtract only) The largest water reservoirs of Russia, such as a reservoirs cascade on Volga and Kama Rivers, are used for solution of a number of water problems including flood control....

Flash Floods and Their Control in the Indian Arid Zone
Flash floods are common hydrologic phenomena in the arid north west India. Drainage basins of high relief, a large percentage of surficial bed rock, sparse vegetation, and shallow soils...

Alternative Urban Flood Control
The hydrological impact of urban growth on urban ecology, water resources, and specifically on urban flooding has been profound. Urban growth in Iran, assuming the continuation of past...

Detailed Measurements of Scour at Bridges
The U.S. Geological Survey, in cooperation with the Federal Highway Administration, has recently developed equipment and techniques for collecting detailed bathymetric and hydraulic data...

Scour Around Circular Piers
In certain situations scour classification becomes sensitive. The generalised scour relationships are superior to classification dependent scour relationships. In this study a generalised...

Temporal Development of Local Scour at Bridge Piers
The temporal development of local scour depth at circular cylindrical bridge piers is considered. New data are presented and used to quantify the influence of flow duration on the depth...

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...

Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...
