The Watershed Modeling System
The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University...
Stochastic Simulation of the Colorado River Flows Using SAMS
The main purpose of this presentation is to illustrate the applicability of SAMS to the Colorado River system. For this purpose we have utilized monthly data at 29 sites in the basin....
Rain and Gray Water Reuse Systems: The Hazard of Legionaries Disease
The Legionaries Disease is being more and more diagnosed. This infectious disease occurs when humans come in contact with the aerosol of contaminated water. The body of knowledge is growing...
New Parameters to Model Ground Motions
The paper presents three new parameters to characterize earthquake-induced ground motions. All three parameters evolve from the concept of response spectra, and are termed 3D response...
Order Amid Uncertainty (Available in Geoenvironmental special issue only)
Bayesian statistical methods allow engineers to deduce probabilities from incomplete information. If there is a theoretical or empirical reason why a particular probability distribution...
Robust Techniques for Extension of Streamflow Records
Longer hydrological records are required for the planning of water resource systems. Sensitivity of a system is studied under various scenarios of hydrological inputs to understand its...
A Statistical Approach to Modeling Groundwater Hydrology in a Constructed Wetland on the Atlantic Coastal Plain, Delaware
The design of wetlands based on groundwater as the principal source of hydrology pose uncertainties in areas where erratic seasonal groundwater fluctuations exist. Under these conditions,...
High-Tech Text
ASCE is involved in two high-tech initiatives that will bring information to engineers in new ways. An interactive textbook for fluid mechanics courses incorporates many advanced visual...
Not Your Father's Strain Gauge
A new type of strain gauge incorporates smart memory methods to assess changes in structures. Inexpensive, easy to install and durable, these gauges are passive peak strain sensors, which...

Potential Microbial Impacts on Groundwater Quality
Over the last decade there has been significant progress in the understanding of sub-surface microbiology. The ubiquity of microorganisms within groundwaters forms a major part of these...
Distributed Parameter Hydrologic Modeling and NEXRAD for River Forecasting: Scale Issues Facing the National Weather Service
With the advent of NEXRAD (Next Generation RADar), the National Weather Service has the opportunity to move from current lumped parameter modeling to more of a distributed parameter hydrologic...
Evaluation of Sampling Properties of General Extreme Value (GEV) Distribution-L-Moments Vs Conventional Moments
The sample estimates of conventional moments are shown to be biased and this bias increases for small samples, and especially so when the skewness is high (Wallis et al., 1974). The recently...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
Rational Design and Operation of Packed Bed Adsorption Reactors
Design of packed bed adsorption reactors is based presently upon the parameter empty bed contact time (EBCT), a fallacious concept. The column wave front behavior, instead, should be the...
Production of Nitrous Oxide Gas under Sequencing Batch Reactor System
N2O, like CO2, H2O, and CH6,...
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...
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...
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...
