Stormwater Quality Issues for Jefferson Parish
Jefferson Parish has a unique set obstacles to overcome in the operation of the drainage system. Situated in a coastal area and surrounded by water, the area has been developed through...
Large Displacement Analysis for Structural Stability Problems
In this paper, two widely different methods of large displacement analyses are considered. The first is a discrete element analysis which is particularly effective for line structures...
A Simulation to Noise Barrier
The problem related to noise barrier is simulated by a still, single frequency, three dimensional sound source located within two parallel screens with rigid back walls. The solution of...
Effect of Stenotic Geometry on Blood Flow Behavior
The dynamic characteristics of the blood flow is affected by the area reduction of stenosis. To estimate the severity of stenosis, the information about the geometry should also be accounted....
In-Mine Hydroelectric Power Generating Station
Mines in the world are continually descending to greater depths in the search of mineral deposits. Water and energy usage are crucial to expansion. To help deal with this problem, Freeport...
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
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...
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....
Hydraulic Roughness and Sediment Yield in Wheel Ruts on Forest Roads
Clear water flow and sediment yield from simulated wheel ruts in a forest road were measured at five different sites in the Northern Rocky Mountains. These measurements provided information...
