Modeling Stormwater Basin Effects
This paper presents results of an extension to a study included earlier in these proceedings on the downstream accumulation effects of stormwater detention basins. The previously calibrated...
Water Quality and Hydrologic Characteristics of a Wet Detention Pond
A small wet detention pond was instrumented to determine treatment efficiencies. Annual loads showed a reduction from the inflow to the outflow for ammonia as nitrogen (39%), organic nitrogen...

Current Blockage Effects on Model-Scale Offshore Platform
This paper presents analysis results of model tests on a 1:47 scale model of an offshore jacket structure under wave-plus-tow (representing wave-plus-current) conditions. The analysis...
Multiphase Flows and the Modeling of Drifting Snow
Three categories of multiphase flow theories are commonly specialized for modeling drifting snow; the 'two-fluid' model, particle tracking schemes and kinetic...
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...
Evaluation of Geoscientific Information Systems for Three-Dimensional Ground-Water Modeling, Yucca Mountain, Nevada
Fully three-dimensional representations of the geologic system at Yucca Mountain have been developed using a Geoscientific Information System, which is an expansion of a traditional Geographic...
Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...
Source Term Model for Radioactive Waste Repository
A radioactive waste repository source term model is developed to predict radionuclide release rates from solidified waste packages disposed of in underground repository. Leach rates, i.e.,...
The Integrated Performance Assessment in SKI Project-90
The SKI Project-90 is a performance assessment of a hypothetical repository system with KBS-3 features in crystalline rock. A large part of the effort has been to identify and characterize...
An Empirical Data Base for the Investigation of Earthquake-Related Changes in Crustal Hydrology
Both fracture permeability and fluid flow velocity can alter as a result of sudden strain changes associated with earthquake fault rupture. Testing the hydrological signatures of numerous...
Strontium Isotopes in Carbonate Deposits at Crater Flat, Nevada
Strontium isotope studies of carbonates from soils, veins, eolian dust and Paleozoic basement sampled near Crater Flat, southwest of Yucca Mountain, provide evidence for the origins of...
GIS Applications Floodplain Reconnaissance Studies
U.S. Army Engineer District, New Orleans (NOD) employed a Geographic Information System (GIS) to support a flood plain management Reconnaissance Study. The study region encompassed the...
A Geographic Information System to Support State-Wide Hydrologic Modeling with the SCS-TR-20
A geographic information system (GIS) that is structured for hydrologic analyses has been installed in the Maryland State Highway Administration's (MSHA) Division of Bridge...
Runoff Modeling Using the Geomorphological Instantaneous Unit Hydrograph and ARC/INFO Geographic Information System
The degree to which the spatial variability of watershed characteristics (geographical and climatological) is recognized for simulating watershed runoff depends on the hydrologic model...
Application of a Geographic Information System to Hydrologic Modeling Using HEC-1
A geographic information system (GIS) was used to derive areally-weighted hydrologic parameters for input to the HEC-1 hydrologic model for approximately 600 square miles of Pierce County,...
Automated Estimation of Hydrologic Parameters
An expert system was developed that automatically generates drainage area boundaries and times of concentration using digital elevation and stream data. Drainage areas and hydrographs...
Corps of Engineers Water Control Data Systems for the 90's
Corps of Engineers water control data systems encompass all of the instruments, equipment, computers, and software used to collect and use environmental data in real-time water control...
