Impact of Urbanization on Storm Runoff
The engineering design of hydraulic structures is directly associated with the estimation of design parameters connected with extreme events. Methods of estimating extreme events typically...
Flow Augmentation in the Fenholloway River Basin
Methods to enhance water quality were examined in a north Florida river basin containing industrial wastewater effluent from a paper pulp mill. Streamflow augmentation was determined to...
The Potential of Mediation for Resolving Conflicts Between Irrigation and Urban Water Users
This paper discusses the potential of mediation as a means of managing and resolving conflict productivity. Conflict over allocation and use of water may arise from technical or substantive...
Without Water Transfers, Cities will Thirst
California will have to depend on water transfers from agricultural areas for at least the next ten years to supply water needed for increasing municipal and industrial (urban) uses. California's...
A GIS Water Planning Model for an Urban and Agricultural Area
Water demand in a region is a mosaic of urban (residential indoor and outdoor, commercial and industrial) and agricultural uses. Yet the typical approach is to aggregate urban water demand...
Effect of Agricultural Drainage on Water Quality in the Northeastern U.S. and Canada
Drainage has been used in the northeastern U.S. since colonial times. It has only been since the 1970s subsurface drains have been installed at a significant rate in Quebec. Drainage in...
Effect of Agricultural Drainage on Water Quality in the Southeastern Coastal Plain
This paper is designed to consolidate selected research and results from investigations of the impacts of agricultural drainage on water quality in North Carolina, South Carolina, and...
Effect of Agricultural Drainage on Water Quality in the Humid Portion of the Pacific Northwest
Agricultural drainage first began in Washington around 1830 and in Oregon around 1840. The first efforts to drain soils for agricultural use began by constructing shallow ditches spaced...
Role of Winter Cover Crops in Reducing Nitrogen Leaching in Sandy Soils
The role of rye as a winter cover crop to reduce nitrate leaching was investigated over a three-year period on a loamy sand soil. a cover crop was planted after corn in the early fall...
Soil Treatment of Food Processing Wastewater
Wastewater from food processing contains a large oxygen demand. Most food processing wastewater requires primary treatment to remove some solids and secondary treatment to oxidize oxygen...
Subsurface Drip Irrigation Can Reduce Pollution
Several researchers have indicated that precise subsurface drip (SSD) application of irrigation water can be effectively used to reduce pollution of the aquifer when irrigating with reclaimed...
Water Transfer: Applicants and Objectors Analyses
Two different analyses of the historical on-farm consumptive use and return flows of agricultural water rights in Northern Colorado are discussed. The City of Thornton plans the transfer...
Lead is a Four-Letter Word
New regulations and strict enforcement make it difficult and expensive to remove lead-laden coatings from steel structures. Lead-based primers and paints are not considered hazardous as...
A Solid Waste Solution
Burgeoning growth and diminishing landfill capacity have been propelling Broward County, Fla. toward a solid-waste crisis. The county, located along Florida's southeastern...
Adaptive Control of Unavoidable Hazardous Releases
This paper presents a procedure for the adaptive control of hazardous releases of toxic substances. In particular, the control strategy is aimed at deliberate releases from man-made storage...
Designing Self-Cleaning Wet Wells for Wastewater Pumping
Guidelines for the design of self-cleaning wet wells for variable speed pumps are given. The progress of research on the design of wet wells for constant speed pumps, including submersible...
Predicting Water Quality at Municipal Water Intakes?Part I: Application to the Contra Costa Canal Intake
The factors affecting water quality at a municipal surface water intake in the Sacramento-San Joaquin Delta are discussed. A model is developed that successfully predicts the seawater...
Predicting Water Quality at Municipal Water Intakes Part 2: Application to the Southern Sacramento-San Joaquin Delta
Work in progress on developing methodologies for predicting water quality at Municipal intakes in the Sacramento-San Joaquin Delta is discussed. Principal sources of salinity are identified...
Sediment Disposal and Transport in Central SF Bay
The relocation of dredged material from navigation channels in the Francisco Bay is crucial to the movement of deep-draft shipping and shallow-draft recreational vessels. The margins of...
Urban Storm Water Instrumentation: a Field Observation
The Dallas-Fort Worth, Texas metroplex has 7 cities with populations of at least 100,000 that are required to meet national Pollutant Discharge Elimination System (NPDES) permitting requirements...
