Design of Penstocks in Severe Earth Slide Locations
This paper deals with the problems of locating a penstock for a small hydroelectric plant at a site in Northern California that experiences considerable land movement during the rainy...

Effect of Frequency on Center Pivot Irrigation
Processes that are affected by the irrigation frequency of center pivot irrigation systems are described. High frequency irrigation will increase evaporation from crop canopies and unshaded...

Overall Resistance Parameter of Flow Arising in the Catchment-Area of a Reservoir in Steep Land
On a small reservoir catchment in mountains, the basin storage S(t) during a flood was expressed in terms of the basin discharge Q(t) and the time-varying storage parameters K(t) and P(t),...

Hydrologic Change Caused by the Eruption of Mount St. Helens
On 18 May 1980, the eruption of Mount St. Helens created a massive landslide which covered 32 square miles and stripped all vegetation from 150 square miles. A study of changes in hydrologic...

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...

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...

A Dynamic Runoff Model for Disturbed Hillslopes
A dynamic runoff model is developed for use in analyzing the hydrologic response of disturbed hillslopes. The model employs an explicit form of the Green-Ampt equation which is coupled...

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...

Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...

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...

Channel Routing Effects on Unit Hydrograph Shape
Channel routing effects on hydrograph shape and the interpretation of downstream unit hydrographs are examined. A new dimensionless routing parameter is presented....

Construction Accident Analysis: The Inductive Learning Approach
This paper presents the use of inductive learning in the analysis of construction accidents. It provides a brief description of ROUGH, an inductive system based on the theory of rough...

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...

Identify the Marina User Market and Make the Customer a Part of the Planning Team: Designing and Managing for the User's Needs
A practical surveying method is described which allows a marketing firm to simultaneously - and quantitatively - analyze demographic market composition (for both upland and in-water uses)...

Stormwater Management: Detention in Illinois
In 1987 the Illinois Department of Transportation contracted the Northeastern Illinois Planning Commission (NIPC) to perform a study to determine the effectiveness of the current accepted...

Utilization of Stormwater Runoff to Recharge Underlying Aquifer
Based on the available data and its proximity to the Capital area, Wadi Al Khawd was selected as the site of the first aquifer recharge project in Oman. The project was designed by Stanley...
