Project Management: Now On-Line
Only 20 years ago, computerized project management was available only to large firms with mainframe computers. Even four or five years back, well into the personal-computer revolution,...

Hydrogeology Comes to the Surface
Before concluding whether groundwater is safe or contaminated, engineers must understand the science of hydrogeology. If they don't understand hydrogeology, unnecessary and...

Use and Calibration of the Layered Muskingum Method to Route Storm Hydrographs on the Sacramento River

Some Examples of Stochastic Linear Reservoirs

Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....

Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...

Incremental Damage Assessment (IDA) For Lake Darling Dam
An Incremental Damage Assessment (IDA) has been completed for Lake Darling Dam, located on the Souris River, near Minot, North Dakota [1]. The IDA has indicated that a reduction in flood...

Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...

Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...

Model Studies for Potential Modification of Pardee Spillway
East Bay Municipal Utility District, a public water supply agency in the San Francisco Bay Area, is examining the spillway adequacy of its primary water supply reservoir. Flood routing...

Design Considerations for Trucks in Work Zones
In an Eastern state a 3. 8 mi (6. 2 km) work zone had 14 accidents during a project duration of 120 days. Eleven of the 14 accidents occurred at temporary crossovers where traffic was...

Computer Spreadsheet Applications to Small Site Drainage Engineering
The computer spreadsheet provides the drainage engineer with a simple, efficient, and adaptable tool for modeling drainage engineering problems. Engineering applications include runoff...

Scodie Canyon Flash Floods of 1984
This paper describes a unique thunderstorm and flood which occurred in Kern County, California in 1984. It describes the follow-up studies and method of implementation of building restrictions...

FLDWAV: A Generalized Flood Routing Model
A new unsteady flow simulation model, FLDWAV, has been developed by the National Weather Service for application on either micro-, mini-, or mainframe computers. FLDWAV is based on an...

Evaluation of Diffusion Models for Flood Routing
A study has been conducted to define the range of conditions with respect to hydrographs and channels encountered by SCS engineers in flood plain/flood control projects and to test two...

Twenty Years of Experience in Unsteady Flow Modeling of Open Channels at TVA
Two concerns prompted the development of dynamic methods for flow routings: (a) the safety of the nuclear plants being planned along the Tennessee River in the 1960's 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...

Capacity Expansion of Water Distribution Systems—A Case Study
Capacity expansion and necessary capital improvements to meet the water supply demand for years 1990-2020 for the U. S. Route 1 corridor development from South Brunswick to Princeton,...

Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....

Sediment Routing and Stream Bed Evolution Model
A one-dimensional numerical model developed by Borah, Alonso and Prasad is discussed, improved and tested. The model named STREAM routes graded sediments and simulates aggradation, degradation...
