2-Framework Development of Hydrometeorological Observational Network and Flood Hazard Mitigation Modelling Systems.

Abstract

An appropriate real-time hydrometeorological observational network is designed and established for developing a full-scale hazard mitigation modeling system in respect of floods covering 24 rivers with an objective to develop an enhanced technical capacity to deal with the floods in future using all available technologies and modeling tools. The framework includes set of hydrological and hydrodynamic models, storm surge inundation assessment along with suitable Geographical Information System (GIS) interfacing for facilitating the quantification and spatial description of the impact offloading (in terms of river and surge inundation) with a sufficient lead-time so as to plan for effective relief routing plans/rehabilitation strategies. Performance evaluation of the hazard mitigation modeling systems for the past flood events is presented in this study.
