RISFramework to Determine Total Maximum Daily Flow Diversions for Fish Protection
Publisher: American Society of Civil Engineers
Abstract: This paper describes a framework to determine the total maximum daily flow diversions (TMDFDs) of freshwater from the San Francisco Bay Delta that can be undertaken without causing the extinction of salmon, striped bass, ...
Decision Support System for Stakeholder Involvement
Publisher: American Society of Civil Engineers
Abstract: Stakeholder involvement is essential to the development of a total maximum daily load (TMDL) and its implementation plan. A tool, beyond a simulation model, is needed to support the decision making process that requires ...
Closure to “Acidification Potential of Snowpack in Sierra Nevada” by Carl W. Chen, Luis E. Gomez, and Lanny J. Lund (July/August, 1991, Vol. 117, No. 4)
Publisher: American Society of Civil Engineers
Modeling the Fate of Copper Discharged to San Francisco Bay
Publisher: American Society of Civil Engineers
Abstract: An existing two-dimensional estuary model was modified to incorporate processes important to the transport and fate of copper in San Francisco Bay. These processes include advection, dispersion, partitioning with suspended ...
Simulating the Effect of Sulfate Addition on Methylmercury Output from a Wetland
Publisher: American Society of Civil Engineers
Abstract: The watershed analysis risk management framework (WARMF) model was applied to Wetland S6 of the Marcell Experimental Forest, using the data from a field experiment, conducted to investigate the effect of sulfate additions ...
Acidification Potential of Snowpack in Sierra Nevada
Publisher: American Society of Civil Engineers
Abstract: Snowpack accumulates water and acid anions from atmospheric deposition. During the snowmelt, the rapid release of acid anions can cause an episodic pH depression in surface water. The potential for the snowmelt to acidify ...
Retrospective Comparison of Watershed Analysis Risk Management Framework and Hydrologic Simulation Program Fortran Applications to Mica Creek Watershed
Publisher: American Society of Civil Engineers
Abstract: As part of an ongoing watershed model comparison program for forested watersheds, Watershed Analysis Risk Management Framework (WARMF V5.18) and Hydrologic Simulation Program Fortran (HSPF V10) were independently applied ...
Effect of Ambient Air Quality on Throughfall Acidity
Publisher: American Society of Civil Engineers
Abstract: Observations at Woods Lake‐watershed in the Adirondacks (New York) indicate that precipitation is further acidified by passage through coniferous canopies; conversely, passage through deciduous canopies has a net alkalizing ...
Investigation of Beach Contamination Using Tracer
Publisher: American Society of Civil Engineers
Abstract: To investigate the potential contamination of a public beach by a nearby duck pond in Marina Del Ray, California, rhodamine B dye is introduced to the pond effluent during an ebb tide. Water samples are collected to measure ...
Decision Support System for Total Maximum Daily Load
Publisher: American Society of Civil Engineers
Abstract: A decision support system (DSS) was developed to calculate total maximum daily loads (TMDLs) of various pollutants for water quality limited sections (WQLS) within a river basin. The DSS includes a watershed simulation ...
