Simulation of Perilithic Algae as a Biofilm and Its Interaction with the Water Column
A one-dimensional bioflim model has been constructed consisting of a particulate phase of algae and inert material and diffusive transport of nutrients and oxygen. Also included is mass...
Neural Networks Predict Pesticide Leaching
The goal of this work was to determine whether artificial neural networks (ANN) can be used to predict the percentage of applied pesticide that leaches through 50 cm of turfgrass covered...
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...
The Last Two Extreme Floods in Germany?Analyses and Consequences
The last two extreme floods in Germany occurred in December 1993/January 1994 and January 1995 within the River Rhine basin with both floods having different causes. In a comparison study,...
On Conductivity of Soils with Preferential Flow Paths
Laboratory soil column experiments were conducted to study the distribution of preferential flow paths resulting from removal of colloidal size clay particles. These experiments specifically...
A Screening Level Model for Estimation of Vadose Zone Leaching and Saturated Zone Mixing: VLEACHSM
A screening level computer model has been developed for the evaluation of pollutant migration through the vadose zone and subsequent mixing within the saturated zone. The model, called...
Sanitary Sewer System Modeling Model Comparison Racine, Wisconsin
As the use of computers continues to increase within the engineering profession, hydraulic computer models are used to simulate major interceptors and sometimes the entire sewer system....
A GIS Sewer Database for a University Campus
The development of a geographic information system (GIS) based sewer network database for the Purdue University campus in West Lafayette, Indiana, is discussed in this paper. The database,...
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...
Design of the Inlet/Outlet Tower for the Eastside Reservoir Project
The Eastside Reservoir is currently being constructed near Hemet, California, by the Metropolitan Water District of Southern California. When completed in 1999, water will enter and be...
Non-Federal Flood Control Works Inspection Program
This paper presents a general description of the Non-Federal FCW Inspection Program and results obtained from the evaluations already completed. A discussion of the GIS package for data...
Stormwater Management Plan Updated for Climate System Changes
When large watershed stormwater management plans are updated, climate system change factors due to global warming effects should be considered. Climate system changes may cause changes...
Channel Junction Effects in Channel Network Flow Simulation
In this paper, the momentum equations, which are applicable at channel junctions, are suggested based on the conservation of momentum flux. In the equation, the lateral inflow angles are...
Modeling the Ecological Impacts of Flaming Gorge Dam Operations
Hydropower operations at Flaming Gorge Dam on the Green River in Utah, U.S.A., can produce rapid downstream changes in flow and stage during a day. These changes can, in turn, affect ecological...
Inundation Studies in Case of Failure of King Talal Dam
In this paper a brief description of the studies is presented and the computed results are summarized. During running the program, several difficulties were encountered. These problems...
Optimization and Simulation in Design and Operation of Reservoirs
Due to stochastic nature of rivers, their volumetric yields are random variables. Spatial and temporal redistribution of Water makes the reservoir construction a must. Therefore, water...
Optimum Storage Reallocation and Gate Operation in Multipurpose Reservoirs
This research is intended to integrate long term operation rules and real time operation policy for conservation and flood control in a reservoir, the familiar yield model has been modified...
