A Gap in the Surface Water Treatment Rule: The Watersheds
Watershed control is required by the Surface Water Treatment Rule of the 1986 Amendments to the Safe Drinking Water Act for systems that do not provide filtration. Where filtration is...
Evaluation and Management of Non-Point Source Pollutants in the Lake Tahoe Watershed
Lake Tahoe, California-Nevada, one of the most oligotrophic lakes in the world, is experiencing decreased water clarity and increased periphyton growth, and water supplies drawing from...
Frequency of the 1993 Flood in the Upper Mississippi River Basin
The frequency of the 1993 flood in the upper Mississippi River Basin is characterized by applying Bulletin 17B and L-moment methods to 111 unregulated watersheds in the basin. The analysis...
A model to describe the fate of agricultural pollutants
The distributed parameter hydrological model CEQUEAU is coupled to nitrogen and pesticide sub-models to study agricultural non-point pollution at the watershed level. This developing tool...
Third Lake Watershed Assessment and Action Plan
Third Lake, located in Lake County, Illinois, is expected to exhibit worsening inlake water quality as development occurs within its watershed. A geographic information system (GIS) application...
Effect of Data Sampling Time Resolution on Probability Distribution of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is useful information in statistical forecasting of rainfall and runoff. The probability density function (pdf) of the elapsed time can be determined...
Riparian Wetlands and Flood Stages
The paper studies concurrent flood stage records from two fourth-order streams in the hills of northwest Mississippi with similar soils, watershed relief and overall land use. The streams...
Combination of an Automated Channel Network Extracting System and a Distributed Watershed Model in Estimation Rainfall-Runoff Processes
Due to the improvement of accuracy and availability of Digital Elevation Models (DEMs), hydrologic researches which utilize DEMs have gradually reached sound results. In this paper, we...
Analysis of the Causes and Triggering Events of Disastrous Torrent Flood
A disastrous torrent flood on the Vlasina River of 26 June 1988 was of unprecedented intensity in Yugoslavia. The catchment area affected by the catastrophe covered more than 1000 km2...
A Watershed Model for Estimating Suspended Sediment Hydrographs
A mathematical model was developed to estimate soil detachment and transport and, consequently, suspended sediment hydrograph for single storms on a watershed basis. In this linear cascade...
Assessing Stormwater Impacts
The evaluation of stormwater effects to watershed ecosystems must adopt an integrated approach due to the inherent complexity of assessing such environments, arising from the vulnerability...
Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....
Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...
Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...
Computer Control of CSOs
Like many older cities, St. Louis has a combined sewer system and is faced with the difficulties of dealing with combined sewer overflows (CSOs). The Metropolitan St. Louis Sewer District...
Resource Implications of Listing Columbia River Basin Salmon Stocks Under the Endangered Species Act
The Columbia River and Snake River dams and reservoirs provide substantial benefits in the Northwest through their operation for hydropower, flood control, irrigation, navigation, and...
Double Rock Park Stream Restoration Project
The Double Rock Park stream restoration is a pilot project for the Baltimore County, Maryland, Stream Restoration Program. The study assessed watershed conditions and the stream channel...
Watershed Management at Three Governmental Levels
Examples of holistic water resources management by the federal, state, and local levels of government illustrate practical application of basic principles of watershed management and public...
A Watershed Approach to Water Quality Criteria
Water quality has been managed historically using water quality criteria implemented through the NPDES permitting process. Many water bodies have water quality better than that defined...
Implementing a Watershed Plan for Lake Stevens
The water quality of Lake Stevens is declining because of watershed nonpoint pollution and cycling of nutrients from lake sediments. Hypolimnetic aeration and an alum treatment are proposed...
