Economic losses and casualties due to rive … Economic losses and casualties due to riverine flooding increased in past decades and are most likely to further increase due to global change. To plan effective mitigation and adaptation measures and since floods often affect large areas showing spatial correlation, several global flood models (GFMs) were developed. Yet, they are either based on hydrologic or on hydrodynamic model codes. This may lower the accuracy of inundation estimates as large-scale hydrologic models often lack advanced routing schemes, reducing timeliness of simulated discharge, while hydrodynamic models depend on observed discharge or synthesized flood waves, hampering the representation of intra-domain processes.<br>To overcome this, GLOFRIM was developed. Currently, it allows for coupling one global hydrologic model, producing discharge and runoff estimates, with two hydrodynamics which perform the routing of surface water. By employing the Basic Model Interface (BMI) concept, both online and spatially explicit coupling of the models is supported. This way the coupled models remained unaffected, facilitating the separate development, storage, and updating of the models and their schematizations. Additionally, the framework is developed with easy accessibility and extensibility in mind, which allows other models to be added without extensive re-structuring. <br>In this presentation, the main underlying concepts of GLOFRIM as well as its workflow will be outlined, and first results showing the benefit of model coupling will be discussed. Besides, current limitations and need for future improvements will be pointed out. Last, current developments in code development, applications, and integrations with other research fields will be presented and discussed.other research fields will be presented and discussed. +
