Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...
Dry Creek Watershed Flood Control Plan: A Case Study
This paper describes the development of the Dry Creek Watershed Flood Control Plan. This study was conducted to quantify the extent of the existing and future (buildout) drainage problems...
Optimization Model for Operation of Recharge Basins
A mathematical model is developed for the optimal operation of recharge basins, which is a non-linear optimization problem. The objective of the model is to determine the operation that...
Water Availability and Water Demand Study for the Citanduy River Basin, West and Central Java, Indonesia
This paper will discuss the water availability and water demands in the Citanduy River Basin located in West and Central Java, Indonesia. A program of development of water and other natural...
Alternative Methods of Drainage Management in San Joaquin Valley, California
The subsurface drainage and drainage-related problems in the San Joaquin Valley cost millions of dollars to the State and local economy every year. A number of actions have been proposed...
Hydropower, Water Quality and Waste Discharge
Development of multiple hydroelectric projects on large river systems can result in potential reductions in dissolved oxygen (DO) concentrations. Municipalities along the Ohio River basin...
The Changing Alliance Between Navigational and Environmental Interests in the ACF Basin
Structural modifications imposed on the Apalachi-cola River for navigation, their environmental impacts and government actions to address these impacts are reviewed. Past structural modifications...
Assessing the Reliability of the Water Supply to a Closed Basin Wetlands
In many reports, it has been predicted that the loss of the Cheyenne Bottoms as a wetlands area would have an adverse effect on a great deal of the North American migratory shore bird...
Ongoing Monitoring Results Pilot Stormwater Disposal Facilities, Pierce County, Washington
The three stormwater disposal facilities evaluated appeared to increase in pollutant removal effectiveness after approximately 4 to 5 months of operation. This may be due to the deposition...
Dry Weather Field Screening as an Indicator for Urban Drainage System Rehabilitation
In November 1990, EPA published final rules governing National Pollution Discharge Elimination System (NPDES) Permit Application Regulations for stormwater discharges. The rules affect...
Efficient Sizing of Storm Water Treatment Ponds
An anticipated result of the NPDES storm water program will be the proliferation of regional storm water ponds that capture and treat urban land surface runoff, thereby improving the quality...
Hillsboro Basin Surface Water Management Model
This study presents the results of the hydrologic and hydraulic analysis of the 103-square mile Hillsboro Basin located in South Florida. The purposes of the project were to develop a...
A Dual Level Methodology for Stormwater Detention Basin Design
A dual level design methodology for designing detention basins has been developed in an effort to standardize detention basin design and expedite the design/review process. The methodology...
Modeling Stormwater Basin Effects
This paper presents results of an extension to a study included earlier in these proceedings on the downstream accumulation effects of stormwater detention basins. The previously calibrated...
Simplified Design of Multi-Stage Outfalls for Urban Detention Basins
This paper presents a simple method for designing multiple stage outlets for detention basins. The method is based on formulas which were derived for the rational and modified rational...
Water Quality and Hydrologic Characteristics of a Wet Detention Pond
A small wet detention pond was instrumented to determine treatment efficiencies. Annual loads showed a reduction from the inflow to the outflow for ammonia as nitrogen (39%), organic nitrogen...
Overview of Permeable Bases
Drainable pavement systems consist of: permeable base, separator lyer, and edgegrain system. This paper focuses on permable bases. A permeable base must provide both permeability and stability....
Performance of Free Draining Base Course at Fort Campbell, Kentucky
In 1990 a free draining base course layer was constructed in the structural section of a pavement to be used as a military vehicle maintenance yard at Port Campbell, Kentucky. The Corps...
The Physiography and Engineering Constraints of the Continental Slope in the Northwestern Gulf of Mexico
The emplacement of structures on the seafloor has always been difficult but until recently, few knew just how difficult possible construction on the Northwestern Gulf of Mexico Continental...
The Thermal Regime Surrounding a Longitudinal Edge Drain
Newton Airfield in Jackman, Maine, was constructed in 1986 to perform as a drained pavement system. The drainage design consisted of a permeable base course with a longitudinal edge drain...
