Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...

Frequency of Flood Extremes
A variety of flood-frequency approaches are reviewed and evaluated in this study. The concept of return period is re-examined and its implication on the meaning of extreme events is given...

Rainfall Intensity-Duration Equations
A method for rapidly developing a rainfall intensity-duration equation for durations less than one hour and recurrence intervals between 2 and 100 years for any location in the conterminous...

Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....

A Shopper's Guide to Urban Stormwater Software, Revisited
Results of a survey of urban stormwater software were first discussed by the author in August, 1985. A trend toward widespread adoption of SCS procedures as a new standard in urban hydrology...

Consulting Engineering
A Guide for the Engagement of Engineering Services
ASCE Manual No. 45, Consulting Engineering?A Guide for the Engagement of Engineering Services, outlines the functions of the consulting engineer in serving a client, the types of services...

Basis for Design of Wet Detention Basin BMP's
Two different approaches have typically been used to formulate design criteria for wet detention basin best management practices (BMP's). One approach relies upon solids settling...

Monitoring and Design of Stormwater Control Basins
The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...

Design and Construction of Infiltration Trenches
This paper discusses the use of infiltration trenches as a stormwater management practice. Feasibility, design and construction techniques are presented to improve the performance and...

Positioning for Success
A model, called the SuperPositioning Model, for successful management of engineering design firms is discussed which allows firms to be categorized within a matrix bounded by two primary...

Electric Utility Planning and Forecasting for Customer Generation

Runoff Model for Watersheds of Nonhomogeneous Characteristics
A watershed of any configuration, topography, and spatial distribution of cover, soil and channel characteristics is described as a plannar grid. Time-varying precipitation is applied...

Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...

Are Soil Moisture Accounting Models Needed for the Real Time Forecasting of River Flows?
The difficulties inherent in using conceptual rainfall-runoff models in conjunction with filtering techniques, for the real time forecasting of river flows, are reviewed. The issue of...

Effect of Rainfall Intensity Distribution on Excess Precipitation
The effect of the time distribution of rainfall intensity on the prediction of the depth of excess precipitation is evaluated. A comparison is made of the excess precipitation produced...

Urban Stormwater Drainage Design by Modified ILLUDAS
The Illinois Urban Drainage Area Simulator (ILLUDAS) has been extended for continuous simulation by considering dry periods between storms. The model accepts predetermined hydrographs...

A Possible Definition of the Input Function for a Rainfall-Runoff Model with Lumped Parameters
It may be useful to introduce, instead of a 'mean areal rainfall', another input function, defined as that input which is transformed by the model into a known...

Emerson, Iowa Flood Warning System
A flood warning system was installed in 1985 by the Corps of Engineers at Emerson, Iowa as part of Emerson, Iowa Flood Control Project on Indian Creek. The warning system consists of two...

The Storage Matching Technique of Detention Basin Design
In recent years, use of continuous rainfall - runoff simulation with historic rainfall data has become much more popular for the design of detention basins and reservoirs. While it may...

Flood Operation Studies of the Valdesia Reservoir System in the Dominican Republic
The Valdesia reservoir system, located on the Nizao River in the Dominican Republic, is designed to provide irrigation water to the Nizao project areas and hydroelectric energy to the...
