Genetic Algorithms for the Design of Groundwater Remediation Systems
The performance of genetic algorithms (GAs) to solve optimal aquifer remediation design problems is investigated. Some difficulties associated with GA models include premature convergence,...
Flow through Vertical Barrier Screens—Numerical Model
A simple one-dimensional numerical model based on the energy equation is developed to predict the normal flow distribution through barrier screens composed of several vertical segments...
White River Fish Screen Project Planning and Design
In 1983, Puget Sound Power and Light Company (Puget Power) submitted a license application to FERC for the overall White River Project. One of the elements of the project application was...
Experimental Uncertainty and Measurement Errors in Hydraulic Engineering
The Task Committee on Experimental Uncertainty and Measurement Errors was formed to provide information and guidance on current practices used for describing and quantifying measurement...
Coastal Engineering Laboratory and Field Measurements: Some Uncertainties in Measurement
In this paper two examples of uncertainties which can occur in field measurements and measurements in coastal engineering models are examined. These examples are chosen to demonstrate...
CSO Planning Model Development and Verification Strategy
A model verification technique is described that uses modeled and monitored overflow occurrences defined in terms of the same long-term frequency statistics that are used to evaluate CSO...
Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...
Plans for Testing and Evaluating the New Autoventing Turbines at TVA's Norris Hydro Project
As part of TVA's Hydro Modernization Program, the two 59-year old Francis turbines at Norris Dam have been upgraded with new units. In conjunction with TVA's...
The Importance of Water Depth for Sparger Performance
As part of TVA Hydro Modernization Program, the two 59-year old Francis turbines at Norris Dam have been upgraded with new units. In conjunction with TVA's Reservoir Releases...
Scour in Erodible Rock II: Erosive Power at Bridge Piers
Scour depths around bridge piers founded on erodible rock can be determined by making use of the Erodibility Index Method. This method defmes an erosion threshold by relating the erosive...
The Balanced Indigenous Population (BIP) and Statistical Process Control (SPC) in Marine Pollution Ecology
This account discusses the regulatory requirement of maintaining a Balanced Indigenous Population (BIP) as it relates to an ocean outfall. A brief history of the development of the BIP...
Looking for Evidence of Climatic Change in Streamflow Time Series
The principle of stationarity of a streamflow time series has been very commonly assumed in the analysis of hydrologic time series. Some common types of non-stationarity in time series,...
Watershed Characteristics and Hydrological Parameters vs. Sediment Yield—Northern Regions of Pakistan
In order to manage, restore, or effectively maintain a watershed it is necessary to know what is really going on inside that watershed, which includes the effects of watershed and hydrological...
Identifying Trends from Streamflow Records—A Case Study
Historical streaniflow records for the Ruby River, in southwestern Montana were analyzed for trends and for changes in the precipitation-runoff relationship. Trends were first identified...
Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...
Uncertainty in Comparative Analysis with Continuous Nonpoint Source Pollution Models
There have been few attempts to quantify the impact of parameter uncertainty in comparative analysis with continuous nonpoint source pollution models. This paper presents the results of...
Hysteresis Effect of Karst Vadose Zone in Spring Kr5, Mt. Kräuterin, Austria
Hysteresis effect is considerable in Spring Kr5, involving a chain of processes of recharge-infiltration-discharge. The lag time of each process to another can be briefly summarized and...
A Stormwater Management Plan
Part 2 of the National Pollutant Discharge Elimination System (NPDES) Stormwater Permit requires both sampling and analysis of stormwater and the control of illicit discharges to stormwater...
Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
