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...
HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...
Theory for Development of the TR-55 Tabular Hydrograph Method
Technical Release No. 55 (TR-55), 'Urban Hydrology for Small Watersheds,' was originally developed by the United States Soil Conservation Service (SCS) in the...
TR-55 Microcomputer Implementation
Microcomputer software is now available which implements the Soil Conservation Service's recently revised 'Urban Hydrology for Small Watersheds',...
Interagency Standards for Automated Local Flood Warning Systems
The need exists for establishing guidelines and standards for aspects of local flood warning systems. The demand for increased flood warning systems is expected to increase due to the...
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...
The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...
Denver Area Real Time System
This paper presents a discussion of the development of the Denver Area Real Time System which will be used to regulate the Denver reservoir system on a real-time basis. Its main components...
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...
Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...
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...
