Framework development of hydrometeorological observational network and hazard mitigation modelling systems in respect of floods and cyclones

An appropriate real-time hydrometeorological observational network is designed and established for developing a full-scale hazard mitigation modelling system in respect of floods covering 24 river systems and cyclones covering nine coastal districts of Andhra Pradesh, east coast of India with an objective to develop an enhanced technical capacity to deal with the floods and cyclones in future using all available technologies and modelling tools. The framework includes set of hydrological and hydrodynamic models, set of regional specific models of cyclone prediction, wind hazard assessment, storm surge inundation assessment along with suitable Geographical Information System (GIS) interfacing for facilitating the quantification and spatial description of the impact of flooding and cyclone damage (in terms of storm surge inundation and wind damage on structures/infrastructure) with a sufficient lead-time so as to plan for effective relief routing plans/rehabilitation strategies. Performance evaluation of the hazard mitigation modelling systems for the past flood and cyclone events is presented in this study. Copyright Springer Science+Business Media, Inc. 2007
