Integrated Hydrologic-Hydrodynamic Inundation Modeling in a Groundwater Dependent Tropical Floodplain

The rapid development of free and open-access hydrological models coupling framework tools continues to present more opportunities for coupled model improved assessment floodplain hydrology. In this study, we set up an Upper Zambezi a fully spatially hydrological-hydrodynamic the Barotse Floodplain using GLOFRIM (GLObally applicable computational FRamework Integrated hydrological–hydrodynamic Modelling). hydrodynamic used are WFLOW LISFLOOD-FP, respectively. simulated flows generated by wflow upstream gauge stations before were quite similar closely matched observed flow as indicated evaluation statistics; Chavuma, nse = 0.738; kge pbias 2.561 RSR 0.511; Watopa, 0.684; 0.816; 10.577 0.557; Lukulu, 0.736; 0.795; 10.437 0.509. However, even though was able simulate hydrology very well, results at outlet did not match monthly Senanga station statistics: 0.132; 0.509; 37.740 0.9233. This is mainly because representation both channel hydrodynamics vertical processes necessary correctly capture dynamics. Thus, need approach that saves basis developing distributed hydraulic models’ assessments groundwater dependent tropical floodplains such floodplain, in closing gap between assessments. A has potential be implementing adaptive wetland management strategies water resources allocation, environmental (eflows), flood control, land use climate change impact Doi: 10.28991/HEF-2022-03-02-09 Full Text: PDF
