Analysis of Flood Risk Management in the Context of Mathematical Models

Risk of flood comprises of the chances of an event to occur and its possible impact on surrounding areas. Managing the flood risks include the chances of flooding that affects a particular community by reducing the impacts and exposure of floods. The main objective of this research is to analyze models based on flood risk management. There are various models that have been used in this regard. We studied three deterministic mathematical models named as hydrological model, hydraulic model and hybrid model. In this paper, comparative analysis of these models has been done. The models have also been compared on the basis of measurement factors. Comparisons show that every model is applicable in particular scenario on the basis of water level area. We conclude that the hydrological model is considered best in broad level area whereas hydraulic model is suitable in flood complexity situations. While, the hybrid model is used in both flood routing and flood determining modelling cases.
