Micro-Illudas for Urban Drainage Design
The Illinois Urban Drainage Area Simulator (ILLUDAS) was developed at the Illinois State Water Survey in 1969 and has been available for use on mainframe computers since 1974. An enhanced...

Optimal Flood Warning and Preparedness Plans
This paper includes a framework for selecting the optimal investment in warning and preparedness activity. The primary factors which might influence the magnitude of cost and damage are...

A Linked Stream-Aquifer System Model
A linked stream-aquifer system (LISAS) model is described. This model includes a deterministic sequential flow simulation component which generates hydrographs of surface runoff and deep...

An Analytically Derived Distribution Function for Flood Volume
A general stochastic model is proposed to determine analytically the distribution function for flood volume. A flood event in this study is defined as an unbroken sequence of consecutive...

On the Choice Between Annual Flood Series and Peaks Over Threshold Series in Flood Frequency Analysis
Statistical techniques are often used to estimate extreme flood events for the design of a flood-control structure or for any other flood-related purpose. Two kinds of models are commonly...

A Versatile Methodology for Flood Frequency Analysis
Many observed annual flood series exhibit reverse curvatures when plotted on lognormal probability paper. The occurrence of these curvatures may be attributed to storm and basin factors....

Comparison of Hydrograph Simulation Techniques Used in Structural Design and Watershed Systems Modeling
This paper describes a basin study in which traditional unit hydrograph analysis methods were compared to the E. J. Inman hydrograph technique. Study results indicate that, where suitable...

A Possible Definition of the Input Function for a Rainfall-Runoff Model with Lumped Parameters
It may be useful to introduce, instead of a 'mean areal rainfall', another input function, defined as that input which is transformed by the model into a known...

Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...

A Geomorphologically-Based Runoff Prediction Model: Case Study of Two Gauged Watersheds in Saudi Arabia
Using the Geomorphologic Instantaneous Unit Hydrograph (GIUH) and via the convolution transformation, a linear discharge hydrograph prediction model is obtained. Infiltration in streams...

Overview of a Real-Time Flood Management Model
A flood management model was developed for the operation of the six reservoirs making up the Highland Lakes System on the Colorado River in Texas. The model allows simulation of over 700...

Groundwater Modeling - A Management Tool
A hydrogeologic investigation within the South Mountain Complex of south central Pennsylvania was performed to develop a groundwater management program. Using LandSat imagery, low altitude...

Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...

Detention Basin Design Using Continuous Simulation
A continuous simulation model is proposed for use in the design of detention basins. The model accepts standard National Weather Service hourly rainfall data as input. The hourly rainfall...

Flood Forecasting Using Local Resources
A dynamic wave flood routing computer program has been used to develop a flood forecasting model for a 5000 mi**2 watershed in lower Michigan. The modeled area covers over 200 miles of...

Real-Time Hydrologic Modeling
The Huntington District of the Corps of Engineers is currently using daily computer modeling for guidance in regulating all nine of its major river basins. Both pool elevation and flow...

Modeling Coal Pile Leachate - A Case Study
Ground water transport of coal leachate from an existing unlined coal storage pile was modeled using the USGS 'Computer Model of Two-Dimensional Solute Transport and Dispersion...

An Application of EPA EXTRAN Model to a Flood Management Study in South Florida
In performing the flood management studies, somewhat unique concerns in South Florida are the backwater conditions due to tidal or non-tidal tailwater, flow reversals from project canal...

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...

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...
