Parameter Estimation and Auto-calibration of the STREAM-C Model

Download or read book Parameter Estimation and Auto-calibration of the STREAM-C Model written by Sumit Sinha and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The STREAM-C model is based on the same algorithm as implemented by the Steady Riverine Environmental Assessment Model (STREAM), a mathematical model for the dissolved oxygen (DO) distribution in freshwater streams used by Mississippi Department of Environmental Quality (MDEQ). Typically the water quality models are calibrated manually. In some cases where some objective criterion can be identified to quantify a successful calibration, an auto calibration may be preferable to the manual calibration approach. The auto calibration may be particularly applicable to relatively simple analytical models such as the steady-state STREAM-C model. Various techniques of parameter estimation were identified for the model. The model was then subjected to various techniques of parameter estimation identified and/or developed. The parameter estimates obtained by different techniques were tabulated and compared. A final recommendation regarding a preferable parameter estimation technique leading to auto calibration of the STREAM-C model was made.
