![]() ( 2016) investigated flood risk in Malaysia and Côte d'Ivoire, respectively. Wondim ( 2016) investigated the flood risk and hazard in Ethiopia's Lower Awash Subbasin. 2021) examined flood susceptibility zones in Slovakia and Ethiopia using a GIS-based multi-criteria evaluation. 2016 Vojtek and Vojteková 2019 Desalegn and Mulu 2020 Hussain et al. Several flood hazard assessment studies have made use of multi-criteria analysis (MCA) techniques. Kron ( 2002) defines formalized.įlood-inundated areas have been mapped using a combination of geographical information system, remote sensing and multi-criteria decision analysis (MCDA) approaches (Fernández and Lutz 2010 Danumah et al. River flooding is caused by excessive precipitation and/or melting snow, which causes rivers to overflow their banks and cover territory that is normally not covered by water. With the exception of flash flooding, which occurs only in the foothills, most floods build up over hours to days. River/stream overflow, heavy rain, breaches in flood protection systems, and rapid melting of ice in the mountains are among the most prominent. ![]() Flooding can occur in a number of different ways. ( 2010), and can cause irreversible damage. Flood came in second place among natural disasters, trailing only drought (OFDA 2012).įloods are among the most shocking natural disasters, according to Rozalis et al. Between 19, Ethiopia experienced 86 natural disasters, resulting in the loss of 313,486 human lives, the displacement of 57 million people, and an economic loss of US$ 31.7 million. Flooding is one of the most common natural disasters, often with disastrous consequences, affecting 170 million people worldwide each year (Kowalzig 2008 Mezgebedingil and Suryabhagavan 2018). However, it has the potential to cause death, displacement, and environmental damage, all of which could jeopardize economic progress. ![]() As a result, flood prediction, early warning and management practices could be implemented on a regular and sustainable basis.įlooding is a natural part of the hydrological cycle. According to the findings of this study, approximately 43.28 and 13.09% of the area were vulnerable to high and very high flood risk zones, respectively. The collected data were processed using the ArcGIS environment and the analytic hierarchy method to produce a flood danger map. The opinions of public institutions and expert decisions were gathered to determine the weight of the factors in the analytic hierarchy process. The basic flood-producing factors in this study were derived from soil, slope, elevation, drainage-density and land use land cover data. The study was aimed to assess flood danger and map inundation areas in Ethiopia’s Teji watershed, which is prone to flooding. Flooding is becoming more severe and frequent as a result of climate change and an increase in human-induced land-use changes, which puts pressure on river channels and causes changes in river morphology. Floods have destroyed people’s lives as well as social and environmental assets.
