Abstract

Inundation has much impact on quantity of water resources as well as regional climate. This study aims at developing in-land water cycle model considering inundation, especially evapotranspiration loss, and estimating river discharge and spatio-temporal changes of inundation area. This study presents basically following three ways of coupling river routing model to land surface model SiBUC . (1)Calculating river routing using kinematic wave equation. (2)Coupling to CaMa-Flood . (3) Interactive coupling between SiBUC and CaMa-Flood. The third way is expected that it enables SiBUC to estimate fluxes on land surface process considering horizontal transfer of surface water storage among sub-grids. These three presented ways are applied to White Nile river basin for mainly estimating water budget and spatio-temporal changes of inundation area in Sudd wetlands area, and compared among the results of them. As a result, a lot of water resource is lost in inundation due to evaporation.<br>
