Probabilities of Hydrologic Extremes and Risk Analysis
Extreme floods of very low probabilities, e.g., 10-6 and 10-7, are estimated using data on annual flood peaks...
Risk-Cost Principles for Dam Safety Analysis
The purpose of this paper is to present the principles and issues of risk-cost analysis as they have evolved in the evaluation of dam safety improvements. The paper also reviews some results...
The Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
Global Climate Change?Implications for Large Water Resource Systems
Prospects of global climatic change resulting from the greenhouse effect are causing increasing concern. Predicted increases in average global temperatures are likely to be accompanied...
Hydrologic Implications of Global Warming on Water Resources in California
The possible effects of climate change on the water resources of the Sacramento-San Joaquin River Basin, as predicted by general circulation models (GCM's) were evaluated...
Issues of Detectability of Climate Change Impacts on the Runoff of a Southeastern River Basin
Can we detect and predict changes in hydrology caused by climate changes? Assuming credible predictions of climate change, can we predict corresponding hydrologic effects? Are uncertainties...
Geostatistics: From Mining to Hydrology
Geostatistics originated in the mining industry to help estimate the amount of metal contained in a block or ore, from a systematic sampling of the block. In this paper, the major geostatistical...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Prediction Using Geostatistics and Mathematical Models
This paper discusses a new interpretation of geostatistical estimation and presents some thoughts on the meaning of probabilities in geostatistics and the role of mathematical models of...
Impact of Risk-Based Analysis on Hydrologic Design Practices
This paper provides a brief review of the current hydrologic design practices of the U.S. Army Corps of Engineers (USACOE) for safety inspection of dams and the current hydrologic design...
Estimation of the Probability of a Precipitation Event Occurring Over a Specified Watershed
A methodology is proposed for making rational flood control decisions when the physical characteristics of the upstream watershed are known and the characteristics of the extreme precipitation...
Cocohatchee River Basin Study
The report presents the modeling of the Cocohatchee River basin, including 2-D routings for wetland regimes, hydrologic/hydraulic analyses of the agricultural and suburban land uses, and...
A Synthetic Simulation Model of Storm Surge History and Inland Drainage in Coastal Zone Areas
In this paper, a synthetic storm surge model is proposed. With the input information of peak surge height, storm duration, and shape coefficients, this model is capable of simulating most...
Low-Land Hydraulics and Hydrodynamics
A hydrodynamic model is presented for simulation of wetland hydrodynamics. The model incorporates all elements of the hydrologic cycle, such as precipitation, runoff, groundwater seepage...
Santa Ana River Project Overview
The Santa Ana River Project, authorized for construction by the Water Resources Development Act of 1986, is designed to provide urban flow protection to the growing communities in Orange,...
Extraction of Terrain Features from Digital Elevation Models
Digital elevation models (DEMs) are being used to determine variable inputs for hydrologic models in the Delaware River basin. Recently developed software for analysis of DEMs has been...
Geographic Information System/Watershed Model Interface
Geographic information systems allow for the interactive analysis of spatial data related to water-resources investigations. A conceptual design for an interface between a geographic information...
Interfacing Geographic Information System Data with Real-Time Hydrologic Forecasting Models
This paper discusses a plan to incorporate remotely sensed spatial data into a real time hydrologic decision support system. Because of the nature of the hydrologic forecasting system,...
The Illinois GIS and Hydrologic Database
Development of the Illinois Geographic Information System (GIS) from 1983 to the present is described including the hardware configuration and ARC/INFO software. The database design at...
Evaluation of TR-55 on Coastal Watersheds
Results of a study of the applicability of TR-55 to coastal watersheds are presented. Historical data were used to evaluate curve number, time of concentration and unit hydrograph peak...
