Investigation of Existing Flood Protection Measures Upstream of Rasul Barrage
Journal Title: Journal of River Engineering - Year 2015, Vol 3, Issue 1
Abstract
Floods in Pakistan have caused a huge loss of life and property. Use of HEC-RAS computer simulation model can help to improve flood protection measures to minimize flood damages. This study was conducted from downstream of Mangla Dam to the upstream of Rasul Barrage. This particular reach has populated towns and villages on both sides of the bank that can be inundated in case of high flood. The measured data for the reach was location and height of the existing flood protection measures on both banks of the river and the geometric data of the reach. This data set was collected from NESPAK Hydrological Division. The obstruction of the reach was Jhelum Rail cum Road Bridge and its geometric data was entered in the model. The flow data of 1997 flood was used for calibration and the 1992 flood data was used for validation. Simulations of discharge closely matched observed data showing model efficiency. The existing flood protection measures were evaluated for the floods of 1992 and Maximum Design Flood (MDF) discharge for Mangla Dam of 61977cumecs. The model simulations identified four locations within this reach that have insufficient embankment height. These results indicate that the embankment height at these locations must be increased to make these specific areas safe against flood. Also this study serves as a guideline for modelling complete length of River Jhelum for future researchers to investigate the existing flood protection measures.
