Recent advances in large-scale flood modeling and its applications

Résumé: 

Recent studies have given special attention to the development and improvement of river routing schemes (RRS) since they can have multiple applications in hydrological studies. For example, in a data assimilation (DA) framework, RRS can be applied to evaluate how DA of different datasets (soil moisture, snow cover, surface temperature, water elevation, etc.) improves the water budget by comparing observed and simulated streamflows. It can also be used to provide a better understanding of surface water dynamics and to evaluate and improve water and energy budgets simulated by land surface models (LSMs). Progress attained with such developments can ultimately improve flood simulations and forecasts, along with the evaluation of water use impacts on the environment, society and economy at the basin scale. Several river routing approaches have been suggested in the last few decades, differing among them in terms of physical complexity and spatial and temporal resolutions. This seminar outlines a few modeling attempts combining the Hydrological Modeling and Analysis Platform (HyMAP) and LSMs, integrating both ground-based and satellite data. Recent improvements in HyMAP, including its recent implementation in the Land Information System (LIS) and applications, will briefly be presented.
