Storm Sewer Computer-Aided Design and Uncertainty
A micro-computer based storm drainage model is presented which facilitates urban storm sewer design on fast tracked construction projects. The model is an interactive Basic program using...

Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...

The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...

Rainfall Results of the Florida Area Cumulus Experiment and Their Implications for Drought Problems in the South
Evidence is presented for treatment effects during the Florida Area Cumulus Experiment (FACE). The sizes of the apparent effects are a function of scale, largest for the cell scale and...

Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...

Evaluation of Cloud Seeding: Southern Great Plains
One of the important aspects of planned weather modification in the United States is that many operational, non-experimental cloud seeding projects have occurred since 1950. Further, several...

Principles for Coastal Zone Management in South Africa
The southern tip of the African continent is characterized by a wide variety of coastal environmental conditions, ranging from a steeply tilted topography with sub-tropical summer rainfall...

Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...

Stormwater Routing for Small Sites
Traditional hydrologic analyses and detention design procedures are too time consuming and costly to be warranted for small projects. This paper discusses a direct solution for sizing...

Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...

Real-Time Flood Forecasting on Small Computers
A real-time, rainfall-runoff, flood forecast model, developed by the Corps of Engineers Hydrologic Engineering Center (HEC), was applied to two of tributary basins in the Ohio River System....

Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....

Numerical Models for Two-Dimensional Surface Runoff
Numerical models for surface runoff in watersheds having two-dimensional or horizontally varying topography are presented. Two finite element methodologies, a standard Galerkin and a streamline...

A Hydrologic Model Developed for Microcomputers
An event oriented hydrologic catchment model has been programmed for use on a microcomputer. Because the program is written in PASCAL, it uses features of this language that eliminate...

Applications of Discrete-Element Computational Models to Transient, Multi-Dimensional Problems in Hydrology
The direct computer simulation technique, discrete-element method (DEM) was applied in the development of transient, multi-dimensional mathematical models for simulating hydrologic conditions...

Time and Space Resolution for Continuous, Dynamic Storm and Runoff Model Studies
Continuous modelling correctly reproduces start-up values of storages and loss rates and statistics for properties of hydrographs. Kinematics of storms should be considered. The effects...

SCS User-Defined Storm Hydrograph (SCS-USH)
The Soil Conservation Service User-Defined Storm Hydrograph (SCS-USH) has been developed to provide engineers and regulatory officials with a simple microcomputer tool for defining design...

Batang Ai?Transition Zone
The Batang Ai Dam in Sarawak includes two concrete faced rockfill embankments. The transition zone between the concrete face and the rockfill consisted of natural river gravels but some...

It? Dam?Selection of Type
This paper describes the studies carried out for the type of dam selection for the Ita Hydroelectric Project. Drastic rainfall conditions, large river diversion flows and an abundance...

Development of Flood Peak Regression Equatins for Small Watersheds in Southwest Florida
Hydrologic investigations were performed on the Belle Meade-Royal Palm Hammock area in Collier County, Florida. The study area, encompassing approximately 79 square miles (205 km**2),...
