The Corps of Engineers has a need for radar information to enhance rain gauge measurements in determining average rainfall over a particular basin for hydrological forecast models used...
Flushing Characteristics for Harbor Planning
A two-dimensional hydrodynamics model was used to understand the circulation and transport patterns in Keelung Harbor, Taiwan. The calculated hydrodynamics information was used to determine...
Central Valley Groundwater and Surface Water Model: A Conjunctive Use Planning Tool
A three dimensional finite element groundwater simulation model is integrated with a surface water simulation model to evaluate the conjunctive use feasibility for a specific area. The...
Utilization of Weather Radar for Hydrologic Forecasting
New technologies to collect, analyze, store, retrieve and display hydrologic data offer significant improvements to conventional methodologies used for predicting hydrologic events. Computer...
Using Climate Model Output to Assess the Impacts of Climate Change on Water Resources
The use of general circulation models (GCMs) to provide climate data for regional assessments of the impacts of changing climate on water resources stretches the limits of what the models...
Guidelines for Water-Resource Planning under Cliamte Change
This study combines the use of several standard tools of hydrology (synthetic hydrology, flood risk analysis, reservoir simulation) with newer considerations of increased demand for water...
Projecting Climate Change to Small Basins: Potential Impact of Global Warming on Hurricane-Induced Flooding in South Florida
An important difficulty in evaluating potential hydrologic impacts of climate variability is that predictions of climate change require global simulation models that do not resolve phenomena...
Urban Hydrologic Modelling: HEC's Experience
Urban hydrologic modelling began at the Hydrologic Engineering Center (HEC) with the first versions of the HEC-1 Flood Hydrograph Package. The early applications were for large, primarily...
Uncertainty in Urban Hydrologic Modeling
Uncertainty is pervasive in hydrologic modeling. Uncertainty is present in the formulation of the physical situation to be modeled, in the form of the model to be used, in the boundary...
Model Mania in Urban Hydrology: Present Dilemmas
A recent ASCE Task Committee on microcomputer software in urban hydrology has just completed its inventory of 40 software packages available at modest cost to the urban drainage engineer....
Unification in Estimation of Confidence Intervals
One area of future development needs in technology pertaining to surface runoff hydrology is the unification of techniques used by govermental agencies in the estimation of surface runoff...
Hydrologic Modeling for Decision-Makers
All Properties within a community benefit from having an adequate system of storm drainage facilities and controls. Such benefits include: reduction of hazards to property and life resulting...
A PC Method to Compile Land Use Data for Hydrology
A computerized method for compiling and reducing land use data for hydrologic computer model simulation was developed. The technique was developed for use on an IBM compatible PC. The...
The Use of GIS in the Study of Water Resources
GIS is becoming an increasingly important tool to the water resource plannar and manager. However, in order to integrate GIS effectively into this field, current and future hydrologists...
Integration of an ARC/INFO GIS with HEC-1
A hypothetical watershed was constructed to test the efficacy of using an ARC/INFO Geographic Information System to provide input for the U.S. Army Corps of Engineers HEC-1 hydrologic...
Monitoring the Physical Evolution of Tidal Wetland Restoration Projects
Increased knowledge of the ecology, biology, and physical processes of wetland environments in the last several decades has improved the awareness of the critical role these environments...
Problems Associated with Deterministic Modelling of Extreme Beach Erosion Events
Recent developments in numerical modelling of cross-shore sediment transport and beach profile evolution have generally been based on a deterministic approach to the problem. That is to...
Biological Methods for Air Decontamination: Modeling Hydrocarbon Removal
Bench-scale tests indicate biofilter treatment of gasoline and diesel with activated carbon support media is first order, while removal of ethanol on compost is zero order. Treatment of...
Hydraulic Model Studies for Non-Federal Projects at Federal Dams?A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...
Decision Rules for Reservoir Releases
One of the problems faced with computer modeling of a multi-reservoir, hydro-power system is making decisions on how releases will be made. Reservoirs many times have multiple demands...
