MAIPARK created the Rapid Flood Model to assist Indonesian general insurance companies in estimating the impact of losses due to floods that are increasingly frequent in the country.
The Rapid Flood Model was developed using a hydrodynamic model based on rainfall and topographic data/Digital Elevation Model (DEM). Rainfall data was obtained from gsmaP rainfall observation satellite estimates corrected with synoptic observation data from BMKG. Meanwhile, topographic data uses the National Digital Elevation Model (DEMNas) from the Geospatial Information Agency (BIG) which is reconditioned using river network data. These two data, after combining with evapotranspiration and infiltration values, will be the input of hydrological and hydrodynamic models to estimate the height and area of the flood basin.
President Director of PT Reasuransi MAIPARK Indonesia Kocu Andre Hutagalung said this model was first applied to the Makassar flood in mid-February 2023. MAIPARK will optimize this Rapid Flood Model through the automation of its calculation process. The target is that within 1 x 24 hours all insurance companies will get the results of the model so that this model can also estimate insurance losses that may occur.
The utilization of this Rapid Flood Model can be optimal because of the database management in MAIPARK which is already at geolocation resolution (placement of risks right at the latitude-longitude point). This is important because the impact of flooding is very sensitive on the spatial quality of the insurance risk database.
