Feasibility of Modeling Phosphorus Dynamics in Stormwater Wetlands
This research, underway at the University of Guelphs School of Engineering, studies the feasibility of modeling phosphorus assimilative capacity by stormwater wetlands in cold climates....
Dynamic Analysis of Multi-Pool Irrigation Canal
This paper discusses the dynamic characteristics of an open multi-pool irrigation canal from robustness point of view. In particular, the presence of right-half plane zeros in an open...
Automatic Control of Flocculation Processes
A control system for flocculation, used in water and wastewater treatment operations is being developed. The approach is based on detailed particle size distribution measurements of influent...
Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...
Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....
Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...
Modeling the Lake Decatur Watershed in Illinois to Evaluate Effects of Best Management Practices on Nitrate Loading
The Illinois State Water Survey recently completed a two-year monitoring and modeling study of the Lake Decatur watershed in Illinois to develop land use management alternatives that would...
Modeling SSO's Resulting from Peak Conditions
Miami-Dade Water and Sewer Department (MDWASD) is undertaking the installation and maintenance of a computerized collection and transmission model and peak flow management study. Through...
At-A-Station Temporal Variations in Flow under Drought and Flood Conditions and Associated Sediment Problems
The way flow variations take place with time under drought and flood conditions, in comparison with normal flow condition, has been investigated along with the related sediment transport...
Eddy Pump Dredging Demonstration at Cresta Reservoir
A demonstration test of a new environmentally ifiendly slurry dredging technology using the EDDY Pump, a patented vortex slurry pump, was perfbrmed in 1994 at Cresta Reservoir in northern...
The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...
Uncertainty Analysis of Reservoir Sedimentation
In estimating reservoir sedimentation, a number of uncertainties arise. These are related to annual streamfiow, sediment load, sediment particle size, trap efficiency, and reservoir operation....
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Studies on the Erosion of a Compacted Soil
In the management of water there are certain applications in which compacted soil is used (i.e., dams, embankments, levees, spiliways, and channels). Engineers rely primarily on field...
Reduction of Sediment Loads in DEC Streams
The U.S. Army Corps of Engineers, Demonstration Erosion Control (DEC) project is actively involved in the stabilization and restoration of many drastically disturbed incising streams in...
Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
Vegetation-Induced Drag: An Experimental Study
Open-channel flow models through vegetative canopies require a quantitative measure of the ability of plants to absorb momentum by form drag, which is commonly characterized in terms of...
Rock Foundations
This manual provides technical criteria and guidance for the design of rock foundations for civil works or other similar large military structures. It provides a minimal standard to be...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
