Theory for Development of the TR-55 Tabular Hydrograph Method
Technical Release No. 55 (TR-55), 'Urban Hydrology for Small Watersheds,' was originally developed by the United States Soil Conservation Service (SCS) in the...

Flood Forecasting Using Local Resources
A dynamic wave flood routing computer program has been used to develop a flood forecasting model for a 5000 mi**2 watershed in lower Michigan. The modeled area covers over 200 miles of...

A Real-Time Flood Management Model for River-Reservoir Systems
A flood forecasting model has been developed for the Lower Colorado River Authority that can be used in a real-time framework to make decisions on reservoir operations during flooding....

Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

A Filtering Approach to Flood Routing
Hydrologic river routing and hydraulic channel routing are in general use for flood routing. Both approaches use deterministic mathematical models and treat inflow and outflow hydrographs...

A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...

Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...

Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...

Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...

Explosion Hazards to Urban Structures
Manufacture, storage and transportation of chemicals capable of exploding at energy levels comparable to TNT has increased in recent years. Land areas adjoining such facilities and transportation...

Terminal 18 Entry Facility—Port of Seattle
This paper presents a successful approach that was used in the planning, design, permit coordination, and expansion of the entry/exit facilities at Terminals 18 and 20 at the Port of Seattle....

Parameter Optimization of Dynamic Routing Models
The methodology utilizes approximate cross-sectional properties represented by separate power functions for channel and floodplain, and a very efficient optimization algorithm for determining...

Routing Comparisons in Natural and Geometric Channels
A method of establishing composite geometric cross section shapes hydraulically similar to natural cross sections with flood plains is proposed. The method is based on the nondimensionalized...

Emergency Flood Management, Salt Lake City, Utah
This paper discusses Salt Lake City's response to the floods of 1983 and 1984. Peaks during these years were very high with historic records being set in both years. Management...

Performance Evaluation and Optimization of Transit Operation
This paper discusses the use of a Performance Evaluation Model in evaluating the effect of short term policy changes including fares, service frequencies, route coverage, and route alignment....

Cultivating Community Confidence—The Key to Success or Failure
A successful community participation program proved to be the turning point for federal approval of the Buffalo, New York rapid transit project. This paper details that citizen involvement....

The Improved SCS TR-20 Network Watershed Model
SCS Technical Release 20, 'Computer Program for Project Formulation - Hydrology' (TR-20), has been revised. Major revisions include new procedures for hydrograph...

Optimal Muskingum River Routing
The Muskingum method of river routing is well established and frequently used. An attempt is made to improve the method by optimal selection of the model parameters. The common linear...

Unique Installation Methods for Large Interceptor in Poor Soil Conditions
The construction of approximately 1. 5 miles of a major sewer interceptor in downtown Boston encountered some unique construction challenges. The entire route required dewatering during...

An Operational Dynamic Routing Model for Small Computers
The paper reports on a study to develop an efficient dynamic routing procedure that can be used on an IBM PC/XT microcomputer as the routing component in a comprehensive watershed simulation...
