Effects of Approach Flow Conditions on Pump Sump Design
An important obstacle to the development of a generalized sump design is the variability of flow conditions in approach areas. The geometry and alignment of the areas immediately upstream...
Simulating Evapotranspiration on Semi-Arid Rangelands
Detailed simulations of the surface energy balance using the Simultaneous Heat and Water (SHAW) model were compared with measurements collected at the Reynolds Creek Experimental Watershed...
The Scour at Bridges Management Program in Rhode Island
The Rhode Island Department of Transportation (RIDOT) has developed and implemented a comprehensive two-phase scour susceptibility program for screening and assessment of scour at bridges....
Hydraulic Studies for a Large Wetland
Coastal wetlands are highly biologically productive and provide spawning and feeding habitats for many aquatic organisms. As has happened to freshwater wetlands, about half of the tidal...
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....
Comparison of Stochastic Programming and Robust Optimization Models for Groundwater Plume Containment
Stochastic optimization models for containing a groundwater contaminant plume through the installation and operation of pumping wells are developed. Two related formulations are presented?stochastic...
The Impact of Numerical Precision on Optimal Groundwater Hydraulic Control
The numerical precision retained in the formulation of groundwater hydraulic control optimization problems can have significant impacts on the accuracy of the solution. Sources of imprecision...
Optimization of Groundwater Remediation with DES
Evolutionary Algorithms (EAs) are non-derivative-based and stochastic op timization methods which simulate the natural evolution process. A type of EA, Derandomized Evolution Strategy...
Mobile Bay Scour Analysis for Mobile and Baldwin Counties, Alabama
Scour analyses were prepared for ten bridges and causeways in and around Mobile Bay on the Gulf Coast of Alabama. Interactions between riverine floods on the Mobile River and tidal storm...
Modeling Groundwater Response to a Perimeter Flood
A large industrial facility in the west of France was impacted by a flood in January 1995. Costs associated with the disruption in one week of production were estimated at $15E6 US. In...
Concept Ecology Integrated Project Engineering and Environment; Relating a Project to the Surroundings
The selected alignment of the 27.3 km long Veterans Expressway in Tampa, Florida was constructed for better access to the downtown area from a relatively rural but fast growing area of...
Investigating the Non-Convexity of the Groundwater Quality Management Response Function
Under certain simplifying assumptions, the groundwater quality management model can be considered a function of a limited number of variables that describe both the transport simulation...
Overview of Drought Response Strategies
An overview of drought response strategies in the United States is presented. The paper focuses on tactical strategies for mitigating the impacts of drought conditions. A general structure...
Water Conservation Definitions From a Hydrologic Viewpoint
The definition of water management principles needed to satisfy societys water use objectives requires the use of terms and definitions that clearly describe the effects of various water...
Rethinking Well Efficiency
Many authors have suggested ways to evaluate water well efficiency. Most of these have either compared some form of measured drawdown with theoretical drawdown or measured the fraction...
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...
Hydrodynamic Simulations in Sediment-Carried Contaminant Modeling for the Buffalo River, New York
Accurate prediction of hydrodynamics is of great importance to modeling contaminant transport and water quality in a river and to estimating potential exposure contamination levels in...
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....
