Changing Hydrology - The Middle Mississippi River
Observed daily flow and stage at major stream gages on the middle Mississippi River are numerically and graphically analyzed to quantify and illustrate the magnitude and seasonality of...
Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...
An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...
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...
Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...
Response of Structures to Horizontal-Vertical Earthquakes
In the present work, the responses of a class of hysteretically nonlinear structures subjected to the combined horizontal and vertical random ground accelerations are studied. A massless...
A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...
Time Domain Structural Parameters Identification
Identification techniques for linear lumped-parameters models of vibrating structures are critically assessed using data produced by numerical simulations. The structural model is excited...
Flexibly Connected Thin-Walled Steel Frame Response
The static response of flexibly connected plane frames composed of thin-walled steel members is presented. Analysis capabilities include post-local-buckling strength and elastic semi-rigid...
Modeling Dual-Ring Actuated Signals with TRANSYT-7F
Current and potential future methods of using the TRANSYT-7F computer program to model dual-ring actuated traffic signals are discussed. First the problems encountered in using this fixed-time...
Development of Graphics Displays for the Integrated Traffic Data System
This paper describes the development of interactive graphics displays for the Integrated Traffic Data System (ITDS) and provides technical details on the hardware and software considerations...
Freeway Analysis Using A Micro Version of FREQ
FREQ8PE is a freeway corridor simulation model. It is a batch processing mainframe program written in ASCII FORTRAN IV, which performs three basic functions: simulate freeway queueing,...
