Flood risk information about a region can be acquired through past flood records that occurred in that region*, however, this information when available, could be biased, inaccurate, or totally unavailable. The goal of this project is to create a multi-sourced online flood archive that would represent documentation of historical, large,…

Over the years, satellite observations have been demonstrated as invaluable in flood monitoring, inundation mapping, exposure, and risk assessments in ungauged basins. Some of these ungauged basins located in flood-prone regions also experience recurrent devastating floods. In this work, we evaluated the hydrological characteristics of the 2012 and 2022 floods…

Climate change is increasing the intensity and frequency of precipitation resulting in extreme hydrological events such as flooding. Global megacities situated in proximity to water bodies and floodplains seem to experience recurring devastating floods. Remote sensing and GIS could also provide an understanding of the influence urban expansion patterns have…

Most environmental hazards peculiar to a region are often multivariate, and MCDM analysis allows the evaluation of multiple variables in characterizing a hazard presence in a location. In the study area below, a GIS-based spatial decision model indicates the impact of rapid urbanization on incessant flooding through changes in land…

Floods are a major global disaster resulting in the loss of lives and properties. The devastating impacts are more amplified in ungauged river basins where ground flood monitoring systems are either sparse or absent. Some satellite products such as the Gravity Recovery and Climate Experiment (GRACE) have proven invaluable in…
