Kinematics and Dynamics of Overland Flow
C. Y. Guo combined the kinematic wave approximation with Horton's infiltration formula to analytically solve the propagation of a two-dimensional overland flow on a previous...
Modelling the Effects of Wind on Pavement Runoff
Phase I of this study, the primary focus of this paper, consists of the development of a mathematical model to predict runoff depths from a pavement under uniform wind conditions. The...
Upland Erosion Estimates Based on Rainfall Depth
The probability density functions of rainfall duration and intensity are coupled with a physically-based dynamic formulation of rainfall-runoff-sediment transport for upland areas. When...
Model Complexity Required to Maintain Hydrologic Response
An increasing number of practitioners are using distributed hydrologic models employing kinematic routing. Watersheds are typically represented by a set of overland flow plane and channel...
Sensitivity of CUHP-PC Computer Model
The Colorado Unit Hydrograph Procedure (CUHP) consists of effective rainfall reduction and hydrograph convolution processes. The primary assumption is an one-to-one response between rainfall...
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...
Inexpensive Geo-Coding for Water Utilities
Geo-Coding enables Hackensack Water Company to optimize meter reading and customer service routing; to analyze water consumption data at a micro level, and relate that data to census 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...
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...
