de St-Venant Channel Routing in Distributed Watershed Modeling

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...

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,...

GIS Proves Invaluable in New York Watershed Study

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...

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...

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...

Case Study: Storm Water Analysis of Manatee Pocket in Martin County, Florida
storm water pollutant loading rates from a 6,000 acre urban watershed were analyzed for source determination of contamination to the receiving water. The receiving water body, Manatee...

Free the Elwha|
The Elwha River flows northward from the middle of Washington's Olympic Peninsula to the Strait of Juan de Fuca. As a coastal river basin, it was once home to all five species of Pacific...

Watershed Effects on the Value of Marshes to Fisheries
Watershed size and rainfall patterns are among the factors that influence the extent to which fishery species use estuarine marshes as nurseries. We examined three Texas bays with different...

A First Look Back at the San Francisco Estuary Project
This paper presents an initial retrospective look at the San Francisco Estuary Project (SFEP) from the standpoint of the senior author, who was involved in the project as a consulting...

Coastal Zone Management for Samaná Bay: Integrating Community Needs
Samana Bay is the third most important breeding destination for migrating, endangered North Atlantic humpback whales, site of some of the largest remaining mangrove habitats in the Caribbean...

Master Planning to Resolve Hawaiian Coastal Problems
Kaneohe Bay, Oahu, Hawaii, is an extensive estuary enclosed by a coral barrier reef. Currently, the Bay is heavily used by numerous groups for a range of different types of activities,...

Partnerships Strengthen Watershed Management
In reaching across political and institutional boundaries to manage nonpoint source (nps) programs, agencies are recognizing the need for strong communication, coordination and planning....

Storm Precipitation in Southwest British Columbia
The storm precipitation in a mountainous watershed in the southwestern British Columbia has been studied. Analysis of the spatial distribution of the storm features showed that the precipitation...

Impacts of Climate Change on Evapotranspiration and Runoff in the Tennessee River Basin
Recent climate change studies using general circulation models demonstrated the potential for a 1 to 3°C warming in North America, as well as increases in precipitation and evaporation...
