Developing Peak Rate Factor (PRF) Guidance in Hydrologic Modeling
| 项目名称： | Developing Peak Rate Factor (PRF) Guidance in Hydrologic Modeling |
| 摘要： | The current Texas practice in Peak Rate Factor (PRF) calculation is to adjust PRF after initial Hydrologic modeling, based on the NRCS dimensionless unit hydrograph, has been performed as a rough calibration to expected values. Changes to PRF values have an effect on the peak flow values and the resulting sizes for hydraulic structures. Recommended PRF values for varied watersheds and physiographic regions in Texas was not previously taken into account. The research teams shall complement the work of Project 0-7010 by performing additional tasks including data collection and analysis to establish solid guidance for a range of reasonable PRF values for different hydro-physiographic provinces of Texas based on the distribution of observed PRF values. |
