Transport Model for Aquifer Reclamation Management
A contaminant transport model which is specifically designed for management applications is developed. A key feature is the transient velocity field needed in the solution of the advection-dispersion...
Improved SWMM Applications for Stormwater Management Master Plans: A Case Study of Virginia Beach, Virginia
A case study of a recent master plan for a 16. 5 sq mi watershed in Virginia Beach, Virginia is presented to illustrate stormwater master planning approaches. The analysis showed that...
Shoal Creek Flood Control Plan Austin, Texas
Following the devastating 1981 Memorial Day flood, a comprehensive and innovative flood control plan was developed and implemented for Austin's Shoal Creek Watershed. The...
Multi-purpose Stormwater Detention Facility Completed as First Phase of Englewood, Colorado, Flood Control Project
In 1980 the City of Englewood Urban Renewal Authority proceeded with planning for flood control improvements along Little Dry Creek. The selected plan includes capacity improvements for...
Multiple Parameter Rule Curve for Reservoir Operations
A procedure for deriving operations rules for water supply storage in a multipurpose reservoir, based on physical principles and data analysis, is described. This procedure has several...
Overview--Committee Report on Dam Safety Guidelines
In November 1984 the Surface Water Hydrology Committee appointed a task committee with the assignment to suggest standards for the hydrologic safety design of dams. The committee report...
Modeling Support for Stormwater Management
An innovative 'digitization' procedure has been developed and successfully utilized to accurately and economically prepare and manage the extensive amount of...
Analysis of Drought Indicators
The Pennsylvania Department of Environmental Resources currently monitors five parameters in its regional water supply management program. These are: (1) accumulated precipitation deficit;...
Drought Analysis in the Ohio River Basin
This study formulates the drought series, including drought occurrence time, duration, and deficit volume by the use of daily streamflows and a tracer level of one-half mean value. The...
Mapping of Drought Status in South Florida
The Water Management District (the District) sets regulations to guide water users in conservation of water use in four phases of drought severity. The District's Governing Board is responsible...
The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...
Paleoflood Studies in Colorado
Paleoflood hydrology is the study of botanic, sedimentologic and geomorphic flood evidence remaining in a valley. Paleoflood studies in the Colorado foothills and mountains have been used...
USDA-Water Erosion Prediction Project (WEPP)
The USDA-Water Erosion Prediction Project (WEPP) will develop improved erosion prediction technology based on modern hydrologic and erosion science that will be process-oriented and conceptually...
Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...
Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....
Unified Approach to Reliability-Based Structural Optimization
The purpose of this paper is to present a unified approach to reliability-based structural optimization. The emphasis is placed on recent developments in the field including optimal design...
Geologic Assessment of Seismotectonic Hazards
Design and modification of dams require evaluation of potential seismotectonic hazards based on consideration of the historic earthquake record and deterministic evaluation of geologic...
Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...
Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...
Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...
