The selected Kulsi River\u2014a part of Brahmaputra sub-basin\u2014experienced severe floods in 2007 and 2008. In this study, the Rainfall-Runoff-Inundation (RRI) hydrological model was used to simulate the recent historical flood in order to understand and improve the integrated flood risk management plan. The ultimate objective was to evaluate the sensitivity of hydrologic simulation using different Digital Elevation Model (DEM) resources, coupled with DEM smoothing techniques, with a particular focus on the comparison of river discharge and flood inundation extent. As a result, the sensitivity analysis showed that, among the input parameters, the RRI model is highly sensitive to Manning\u2019s roughness coefficient values for flood plains, followed by the source of the DEM, and then soil depth. After optimizing its parameters, the simulated inundation extent showed that the smoothing filter was more influential than its simulated discharge at the outlet. Finally, the calibrated and validated RRI model simulations agreed well with the observed discharge and the Moderate Imaging Spectroradiometer (MODIS)-detected flood extents.<\/jats:p>","DOI":"10.3390\/ijgi7020051","type":"journal-article","created":{"date-parts":[[2018,2,5]],"date-time":"2018-02-05T06:23:04Z","timestamp":1517811784000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Analysis of Hydrological Sensitivity for Flood Risk Assessment"],"prefix":"10.3390","volume":"7","author":[{"given":"Sanjay Kumar","family":"Sharma","sequence":"first","affiliation":[{"name":"National Institute of Hydrology, Centre for Flood Management Studies, Dispur, Assam 781-006, India"}]},{"given":"Young-Joo","family":"Kwak","sequence":"additional","affiliation":[{"name":"International Centre for Water Hazard and Risk Management (ICHARM) under the auspices of UNESCO, Public Works Research Institute (PWRI), 1-6 Minamihara, Tsukuba, Ibaraki 305-8516, Japan"}]},{"given":"Rakesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"National Institute of Hydrology, Centre for Flood Management Studies, Dispur, Assam 781-006, India"}]},{"given":"Bibhash","family":"Sarma","sequence":"additional","affiliation":[{"name":"Civil Engineering Department, Assam Engineering College, Guwahati 781-006, India"}]}],"member":"1968","published-online":{"date-parts":[[2018,2,5]]},"reference":[{"key":"ref_1","unstructured":"Global Water Partnership (2000).
