Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...

Rainfall-Runoff Characteristics of Rangitaiki and Whirinaki Watersheds
The Rangitaiki and Whirinaki watersheds in New Zealand have considerably higher storage and infiltration rates than others in New Zealand. The Rangitaiki watershed is flat compared to...

Tidal Flooding Analysis, San Francisco Bay
Many leveed areas adjacent to San Francisco Bay are potentially subject to tidal flooding. In response to this concern, Congress authorized the U.S. Army Corps of Engineers to conduct...

Flood Control Design for Development on Alluvial Fans
Hydrology, debris production, sediment transport and hydraulic studies were conducted to provide flood control for a development within an alluvial fan floodplain. Innovative techniques...

The Dilemma of Measuring Small Pressure Changes in a Settling Tube
A compact settling tube was developed to determine fall-velocity and particle-size frequency distributions and specific gravities of sand-range sediment samples by means of direct measurements...

Verification of Clark County Hydrologic Modeling
The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the...

Reliability Assessment Method for Flood Forecasts
Peak discharge predictions produced by rainfall-runoff models and used by flood warning and preparedness agencies are subject to uncertainties in the input data, model parameters, and...

Conventional Storm Drainage Which Recharges the Groundwater
Since the demand for water is on the rise, more resourceful means of retaining and controlling the release of stormwater is needed. This retained stormwater may then be used for aesthetic...

Maintenance of Stormwater Management Facilities: Neglects in Practice
The Stormwater Management Facilities (SWMF) have become a required component of urban development projects in many parts of the country. In spite of differences in size, type, and physical...

Runoff Volume Frequency Estimation
An explicit formula is reported to express the volume of runoff resulting from a single rainfall event in terms of the catchment and rainfall characteristics. This formula is obtained...

Rainfall-Runoff Modeling in a Small Urban Watershed
Knights Branch watershed is located in Dallas, Texas, and it covers an area of about 5 mi² (13 km²). Due to...

Rainfall-Reaeration Effects
The effect of rainfall intensity on reaeration has not been adequately reported in the literature. It is clear that rainfall causes surface turbulence and increases reaeration, and a significant...

On Stochastic Decomposition and Its Applications in Probabilistic Dynamics
The frequency domain analysis concerning the response of cascade-nested multiple input/output systems requires computation of the cross-spectral density matrix involving the input, intermediate...

Transportation Cask Life Cycle Cost Uncertainty Analysis
This paper demonstrates an uncertainty analysis methodology using random sampling. This methodology has been applied to a nuclear waste transportation code, and several transportation...

The Dallas Floodway?Past and Present Successes in Flood Protection Benefits
This paper explores the history of the Dallas Floodway, past performance of the project under various flood conditions and, most recently, the present successes in flood protection provided...

Causes and Possible Control Measures of Flood in Bangladesh
Intensity and frequency of occurrence of devastating floods in Bangladesh have increased significantly over the past two decades. Large scale deforestation in the upstream reaches of Ganges,...

Siting the New Boston Harbor Outfall: Near-Field Analysis
In the near-field analysis for Boston's proposed Deer Island outfall to Massachusetts Bay, multiple initial dilution calculations were applied to estimate the frequency distribution...

Characteristics of Flood-Producing Rainstorms in the Midwest
At the Midwestern Climate Center, a comprehensive re-evaluation and updating of heavy rainstorm frequency relations for 9 Midwestern states is in progress. A special effort is being made...

A Method for Estimating Peak Flows from Small Agricultural Watersheds
An attempt was made to develop a method for estimating peak runoff from agricultural watersheds by analyzing precipitation and runoff data, and incorporating the results into a procedure...

Climate Change and Resulting Hydrologic Response: Illinois River Basin
In the last 20 years, the northern half of the Illinois River basin has been experiencing a wetter and cooler climate. This climate change has significantly increased Illinois River flows...
