Analysis of applicability of flood vulnerability index in Pre-Saharan region, a pilot study to assess flood in Southern Morocco

Abstract

Abstract. Abstract. Moroccan Pre-Saharan zone is an oasis system, which it is characterised by extreme events, like drought and flood. The flood risks will likely increases in frequency and magnitude due to global and regional climate change. Flood tends to have an important impact on isolated and poor regions such as oasis regions. This paper aims the analysis of applicability of Flood Vulnerability Index (FVI) in pre-Saharan region of Morocco. The FVI, it is a numerical index that reflects the status of a region's flood vulnerability. It was determined for four components social, economic, physical, and environmental. These components can help to assist to propose strategies for improvement of the holistic system. For this study five sub-catchments were selected: Upper Draa Valley (UDV), Middle Draa Valley (MDV), Tata sub-catchment, Guelmim sub-catchment and Tafilalt sub-catchment; and five urban areas, Ouarzazate, Zagora, Tata, Guelmim and Errachidia. A comparative analysis of the results from thus areas allows us to assess the applicability of the FVI. The overall FVI for these areas was determined by the calculating and standardisation of 36 indicators for each sub-catchment scale and 34 for each urban scale.

Towards a flood vulnerability assessment of watershed using integration of decision-making trial and evaluation laboratory, analytical network process, and fuzzy theories

“…According to the surveys in literature, applied factors for vulnerability assessment are consist of physical, economic, and social conditions (e.g., Karmaoui et al 2016;Sadeghi-Pouya et al 2017;Kumar and Bhattacharjya 2020). Thus, in this study, we considered important physical and socioeconomic factors based on the available data in the area of the watershed; that are described as follows: .…”

Study of Integrated Social Vulnerability Index SoVIint of Hilly Region of Uttarakhand, India

“…This study focuses on the deriving a map for the hilly districts of Uttarakhand showing the vulnerability incorporating natural, social and economic indicators. In general terms, the vulnerability is described as a chance of being damaged of a person, a system or any environmental related projects which is disclosed to a risk and sensitive to lose [4], [5].…”

“…Some researcher also defined vulnerability on the basis of the political ecological concept as it is the relationship that people have with their environment [7]. Ballica et al stated that the vulnerability is not only important for the survival of the societies to severe floods, but also for their adjustment to climate change [4], [8], [9]. Before starting the discussion on social vulnerability, we should know the basic definition and meaning of words which are similar in nature, but have different meaning in terms of hazard.…”

Cartography of Flooding Hazard in Semi-Arid Climate: The Case of Tata Valley (South-East of Morocco)

“…The table indicates that floods have been the most frequently encountered natural disasters in the country [15]. The number of affected people and lives lost due to floods exceeds any other natural disasters in the past twenty years [16]. In Morocco, there is a need to conduct studies on the flooding potential in the cities located especially in oasis areas, which are most vulnerables than others situated far from the rivers.…”
