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...

Water Distribution Infrastructure Analysis
Water distribution systems in many older cities of the United States need rehabilitation. Because the rehabilitation costs of the nation's water systems will involve billions...

Statistical Analysis of Ground Water Quality Data
The Resource Conservation and Recovery Act (RCRA) requires owners and operators of hazardous waste facilities to utilize design features and control measures that prevent the release of...

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...

Field Data-Gathering: Critical First Step for a GIS
Gathering data in the field is one of the first major tasks required for developing a geographic information system (GIS) or automated mapping/facilities management (AM/FM) system. This...

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...

A Visualization Toolkit for Fluid Mechanics
The increasing complexity of both experimental and computational models in fluid mechanics requires innovative techniques for analysis and comprehension. Visual methods have been shown...

A Substructuring Algorithm for Analysis and Optimization of Large Structures on Parallel Machines
An efficient substructuring algorithm is presented for analysis and optimization of frame structures on parallel machines. The underlying concept is to pre-process the input data in such...

A Kinematic Hardening and Softening Model of Concrete
In the present paper, a new loading surface calibrated by several typical uni- and multi-axial test curves is proposed. Following the associated flow rule, a relatively simple constitutive...

Extracting Dynamics from Ocean Wave Time Series Data
Recent developments in chaotic dynamics have indicated that qualitative information of a dynamical system can be extracted from the observation of a single time series as the time series...

Response Triscpectrum for a Yielding Structure
Simulation is used to obtain information about non-Gaussian aspects of the absolute response acceleration of a bilinear hysteretic oscillator with an excitation which is Gaussian white...

Methodology for Developing an Engineering Solution for Web Crippling
This paper describes the methodology used to develop an engineering solution for web crippling of aluminum trapezoidal sections. The development has two steps. The functional form for...
