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...

Role of Surficial Aquifer in Barrier Island Streamflow Generation
Monitoring results are presented for an experimental watershed located on a South Carolina barrier island. Rainfall, streamflow and well data indicate streamflow occurs due to interaction...

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...

Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...

Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...

Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...

Geographic Estimation of Runoff-Model Parameters
The U. S. Geological Survey is developing techniques to estimate and evaluate unit-hydrograph and loss-rate parameter values for rainfall-runoff models using Geographic Information System...

Trends in Containerships and Their Impact on Terminal Design
A revolution in ocean shipping operations, affecting both landside equipment and cargo handling methods, is underway. In today's container shipping industry, maximum efficiency...

Computer Pricing Practices
Civil engineers have become increasingly involved with the use of computers to help solve engineering problems. Many problems that previously could be solved only approximately, or that...

Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....

Financial Development for Projects
An important element in the total package of Bechtel's engineering and construction services is the financing and commercial assistance offered in support of our client's...

Total Cost Purchase Options Buy vs Lease vs Rental Conversion Cash Flow Analysis
Today's financing alternatives are very complex and sometimes difficult to comprehend. The combined effect of the slow economy and uncertain future workload has accelerated...

Structural Engineering for High Technology Clients
The unique requirements of the high tech industry provide interesting and fascinating challenges to the structural engineer of the 1980's. The following is a list of the most...

Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...

Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...

Assessment of Drought Restriction Needs in New Jersey
Due to insufficient rainfall and related runoff during the spring of 1985, the Passaic and Hackensack River Basins in northern New Jersey and related storage reservoirs therein were able...

Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...
