Chaotic Phenomena of Rainfall and Runoff in Tou Chien Creek

Scientific Basis of Precipitation Enhancement

Wider Ride to the Rainbow
Engineers on the project to widen the entrance to the Rainbow Bridge between New York and Ontario let the aesthetics of the Niagara Falls setting dictate their design decisions. The challenge...

Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...

A Statistical Analysis of Wind Damage to Single-Family Dwellings Due to Hurricane Hugo
The claim files of 575 policy holders of the South Carolina Windstorm and Hail Underwriting Association were analyzed to determine the nature of wind damage to single-family dwellings...

Evaluation of the Return Period of the September 1992 Flood in Genova, Italy
The September 1992 flood in Genova caused great damage and loss of life. The flood peak, at the outlet of a 12.5 km2 basin, was estimated at 200...

Joint Probability Distribution of Rainfall Intensity and Duration
Intensity-duration-frequency (IDF) curves are widely used for peak discharge estimation in designing hydraulic structures. Accurate interpolated and extrapolated intensity values are difficult...

The Economic Cost of Stocking Catchable Rainbow Trout
States annually stock about 20 million pounds of catchable trout in public waters. Complete information on cost is essential to help wildlife agencies make operating and planning decisions....

Peak Runoff Prediction for Small Rural Watersheds
A regression model for peak runoff prediction from small rural watersheds was developed using the rainfall/runoff data collected from 43 watersheds in the front range of the State of Colorado....

Effect of Nonstandard Rainfall Distributions on Stormwater Management Detention Basins
A rural watershed is modeled to determine the effect of varying rainfall patterns on stormwater management detention basins designed for center peaking events. A hydrologic model of the...

Design Aspects of Modeling Reclaimed Water Use
The authors compare design aspects of modeling reclaimed water use with monthly and daily water balance protocols and review state regulations pertaining to use of reclaimed water. The...

Heuristic Knowledge-base Approach to Runoff Estimation in Midwestern States Using a SCS Curve Number Method
The applications of the Knowledge-Based engineering has emerged as a potential technique for incorporating human expertise and some degree of intelligent judgment into decision-supporting...

Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...

Effect of Data Sampling Time Resolution on Probability Distribution of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is useful information in statistical forecasting of rainfall and runoff. The probability density function (pdf) of the elapsed time can be determined...

Combination of an Automated Channel Network Extracting System and a Distributed Watershed Model in Estimation Rainfall-Runoff Processes
Due to the improvement of accuracy and availability of Digital Elevation Models (DEMs), hydrologic researches which utilize DEMs have gradually reached sound results. In this paper, we...

Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...

Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...

Historical Rainfall-Runoff Analysis Using the Antecedent Precipitation Index
A long term simulation of rainfall-runoff can be used when analyzing the potential for economic benefits or flood damages to result from changes in the watershed, for developing discharge-frequency...
