State Space Approach To Flood Stage Estimation, Gregory Allen Jones
State Space Approach To Flood Stage Estimation, Gregory Allen Jones
Dissertations and Theses
A flood routing and stage prediction model is developed using the techniques of State Space and Kalman filtering. The governing equation is the physically based hydrologic method of flood routing with the output being an optimal estimate of stage given known inputs of streamflow. These equations are developed in state space and the Kalman filter is employed to estimate the flow and river stage.
The model is applied to the Toutle and Cowlitz Rivers in the State of Washington, where the stage is affected by a shifting bed elevation. With the deterministic inputs at Mayfield Dam on the Cowlitz and …
A Numerical Solution For Three Dimensional Beam Columns In The Elastic Region, Hamid Reza Afghan
A Numerical Solution For Three Dimensional Beam Columns In The Elastic Region, Hamid Reza Afghan
Dissertations and Theses
The three differential equations describing the behavior of the beam columns in three dimensions are derived and presented in finite difference form. A computer model is developed to solve the simultaneous equations in the elastic regions and predict the member behavior.
The computer program is checked by comparing the results obtained from the program with data from other investigators, and classical analytical techniques.
