Inundation models play significant role in flood disaster management. Pampa River is a tropical, monsoon-fed river in Kerala, India. Its basin experiences severe floods owing to excessive human interference. Some of the streams in this river, which effectively did hydraulic-balancing, dried-up due to indiscriminate human intervention. In this paper, utilising HEC-RAS model, flood plain inundation map of Pampa River Basin is evolved. Scenario of rejuvenating two prominent dried streams simulated and effects of rejuvenation in reducing flood havoc analysed. Study revealed that by revitalising dried rivulets, about 20% reduction in flood inundation area can be achieved, improving flood situation considerably. |
