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...

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...

Nonpoint Source Runoff and Urban Water Management
Urban nonpoint source pollution can be viewed from physiochemical, source, and impact perspectives. These and its dependence upon runoff pose important problems for pollution control management,...

Nonpoint Source Pollution Control & Land Use
Nonpoint source pollution control requires dealing with city, suburban and rural activities, and controlling pollution either at source, by detention basin quality control or by treatment...

Site Specific Hydrological Model for Permaculture Application
This paper presents results of a study conducted on a small pond and watershed in Waterbury, Connecticut. The Soil Conservation Service method presented in Technical Release #55 (TR 55),...

Evaluation of Global Warming Impact on Soil Moisture and Water Runoff in Texas
In this paper a numerical evaluation of the variability of soil moisture and surface runoff due to global warming is carried out. An analytical model of the soil moisture balance based...

A Two-Dimensional Model for Estimating Leachate Flow in Landfills
A numerical model has been developed to compute the leachate flow from solid waste landfills in an unsteady state condition. The two-dimensional moisture flow equation along with the boundary...

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...

Finite Element Analysis of Hillslope Variations in Surface Runoff
Watershed management decisions are aided through an accurate understanding of hydrologic processes. The finite element method applied to surface runoff with spatially variable hydraulic...

Asymptotic Determination of Curve Numbers from Rainfall?Runoff Data
Background, general instructions, and examples are given for determining Runoff Curve Numbers (CN) from small watershed event rainfall and direct runoff data sets. In order to preserve...

Rangeland Evaluation of WEPP Hydrology
The hydrology component of the Water Erosion Prediction Project (WEPP) utilizes the W.H. Green and G.A. Ampt infiltration equation to simulate the rate and volume of excess rainfall. Excess...

Chaotic Characteristics of Snowmelt Runoff: A Preliminary Study
Chaos, the study of nonlinear dynamic systems, offers a way of observing order in systems previously thought to be random. In this study, we analyze snowmelt runoff from a small watershed...
