The objective of this study is to characterized the vulnerability to soil erosion in Constantine city (county seat of the Wilaya of the same name) using a spatial multi-criteria method. The followed approach focused on interaction of several factors (climate, topography, lithology and land cover) Acting erosive process by means of Weighted Linear Combination (WLC) that facilitated the quantification of the global effect of these factors in fine and objective manner. The results show that more than 50% of the city's surface is exposed to high vulnerability, which requires the implementation of soil erosion control measures.

The Geographic Information System (GIS), integrated with its functionalities, represents a powerful and well-adapted tool to solve this problem. This study uses the Analytic Hierarchy Process (AHP) to solve the problem of quantifying qualitative features. It enables users to make intuitive judgments about the relative eight of different predetermined criteria or options in Batna, northeastern Algeria and its neighboring municipalities. The superposition of data related to several characteristics, such as geology, hydrology, and land use, allowed us to overcome several difficulties in evaluating the location of sites suitable for establishing landfills. Results show that 88.498km 2 in total meets the specified exclusion factors, of which 34.098% represent areas of very excellent suitability and 33.741% appropriate areas. Finally, low appropriateness applies to 32.161%.

It is defined as frequent natural phenomena that cause significant and often irreversible human and material damages. The increase in the number of catastrophic floods is first and foremost the consequence of climate change as well as land use that is not in line with environmental reality (construction on floodplain areas, inconsistent development of river beds. This paper represents generalities and definitions which allow an explanation of some fundamental concepts related to flood risk and its management.

Most Algerian cities are exposed to flood risks and suffered from its consequences. The purpose of this paper is the spatialization of flood hazard in the city of Chemora (Algeria) by hydraulic modelling in a GIS environment whose objective is prevention, which requires a set of hydrological and hydraulic informations in order to achieve a comprehensive and effective management.

Therefore, measuring peak flows appears to be not only important but even essential. Due to the absence of hydrometric stations at the outlet of the sub-basins that are part of comprehensive prevention strategy, and were established because of the high vulnerability of the city of Batna, this study provides a transformation model of rainfall into flows in the Batna watershed. This work aims to model the transformation of rainfall into flows. To estimate the Q max, two formulas were used, and Turazza’s seems to be the most adequate, because it demonstrates a cumulative sub-basins flow close to the result recorded by the only hydrometric station at the outlet of Batna Watershed. From this modeling, it is possible to estimate the extreme quantiles with the return periods of 10, 20, 50 a...

Covid-19 is spreading around the world, and particularly in Algeria, which announced the identification of the first case on the 26 February 2020. The number of confirmed cases is increasing day by day. Currently, we experience the spread of the word "resilience" in most diverse research areas and policy fields of modern society. Social resilience is the capacity of a social entity to proactively adapt to and recover from disturbances that are perceived within the social entity to fall outside the range of normal; this includes expected and unexpected disturbances. The main objective of this study is to contribute towards connecting the socioeconomic vectors of this pandemic, and to integrate them into the GIS (Geographic Information System), in order to analyze the level of social resilience in Algeria. The analysis adopted the method known as the Hierarchical multi-criteria analysis (AHP), which defines the relative importance of each characteristics. The findings of our research show that the factors of high unemployment and housing occupancy rates, high population density and the share of citizens aged over 60 directly influence the reduction in the level of social resilience to the novel coronavirus.

The aim of this study is to map the floods hazard using a hydraulic modeling method. In fact, using the operating Geographic Information System (GIS), would allow us to perform a more detailed spatial analysis about the extent of the flooding risk, through the approval of the hydraulic modeling programs in different frequencies. Based on the results of this analysis, decision makers can implement a strategy of risk management related to rivers overflowing through the city of Batna.

Comprehending the spatial distribution of extreme rainfalls that cover the entire catchment area, the impluvium, of Batna, requires as a first step a frequency analysis of annual maximum daily rainfall time series with the application of empirical distributions, namely the GEV distribution, the Gumbel distribution and the log-normal distribution. This has allowed us to estimate the quantiles of extreme rainfall with return periods of 5, 10, 20, 50 and 100 years for ten rainfall stations. Subsequently, this has allowed us to map the quantiles matching the centennial return period using three types of interpolations.

A multi-criteria analysis has been performed in a geographic information system (GIS) by integrating several features relating to socio-economic stakes with the aim of better understanding, assessing and spatializing the level of vulnerability in the city. Therefore, we have used a customised index approach where each parameter is a numerical index indicating the importance of the stakes, resulting in a code to be used for the modelling.
