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...

Microcomputer Graphics Flood Stationarity Test
Only records that correspond with present river conditions should be used with flood frequency analysis when forecasting. A microcomputer test is discussed which aids in selecting appropriate...

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),...

Transient Fluid-Structure Interaction of a Cylindrical Tank with a Flexible Baseplate
Analytically predicted coupled natural frequencies, response functions, and transient responses are compared with measured values for a partially filled cylindrical tank subject to excitation...

Santa Clara Valley Weather Modification Program
This report describes a significant advancement in the Santa Clara Valley Water District's knowledge and understanding of its weather modification (cloudseeding) program,...

Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...

CN Approach to Water Budgets for Small Watersheds
In some states, issuance of a surface mining permit is dependent upon an assessment of the current hydrologic baseline of the area to be mined and of the probable future impacts of mining...

Simple Hydrologic Modeling
Several simple models for estimating precipitation and evapotranspiration from a limited data base are discussed. Rainfall probabilities may be calculated from mean monthly rainfall. Depth-duration-frequencies...

The SNOTEL Data Acquisition System Design, Operation, and Uses
The Soil Conservation Service (SCS), U. S. Department of Agriculture, coordinates measurement of the winter snowpack in the Rockies, Sierra Nevada, Cascades, and other major mountain ranges...

New Developments in Urban Hydrology in France from 1979 to 1982
The period of 1979-1982 is characterized by an important growth of the number of research studies, and financial investments for practical applications of research results. That growth...

Urban Hydrology Progress Since 1979 in the U.S.
Much of the progress in urban hydrology in the U. S. occurred before 1979. Some of the results of activities initiated or reported before that date are just becoming widely known, however....
