Aménagement du TerritoireTags : Bassins versants oued Lagreme et Kissir Érosion Vulnérabilité Cartographie Wadi Lagreme and Kissir watersheds Erosion vulnerability Cartography الحوض المائي وادي كيسير و العقرم التعرية هشاشة تنطي Index. décimale : 711 (Aménagement du territoire) Résumé : The watersheds of the wadis of Lagreme and Kissir know degradations and losses of soil over time. The geo-geomorphological and morphometric properties such as lithology, morphology, slope and vegetation of the two basins are an important factor that promotes water erosion and generally a significant specific solid transport. The action of precipitation is a function of their intensity on the soil, they come into play and cause an erosion often accelerated. The sediments resulting from this soil degradation contribute to the siltation of the reservoir dam. The lithological formations outcropping in the study area have an influence on the installation of a network of ravines and gullies and on the behavior of superficial flows. Slope erosion remains a complex and dissimilar phenomenon from one basin to another; it is irregular within the same basin due to local geo-geomorphological and morphometric conditions. This study aims to establish a hierarchy of watersheds of the two wadis Lagreme and Kissir, based on morphometric indicative indices. The present work also aims to draw up thematic maps using a geographic information system (GIS) of the different processes related to water erosion, such as slopes, lithology, precipitation, and vegetation. The integration in the GIS of the various digital maps, allowed to codify the degree of vulnerability of the various parameters having impact on the water erosion in the two watersheds that are the subject of the study. The spatialization of the risk of erosion was established based on the estimate of the severity of the six factors presenting the parameters of the soil erodibility: slope, lithology, precipitation, flow, land use and lineaments. The additive combination of the various maps integrated into the GIS enabled the mapping of different classes of soil sensitization to erosion: low, medium, strong and very strong. The mapping of the degree of erosion risk was established on the principle of superposition of the different thematic maps developed using a geographic information system. Areas marked by strong and strong erosion sensitivity (orange and red color) in both basins require immediate anti-erosion interventions. Note de contenu : Annexes.

using A classic European macro-seismic method Risk-UE and innovative data mining-based methods
(Association Rule Learning, ARL).
The ARL method consists in establishing relationships between building attributes (number of stories
or building age) and the vulnerability classes of the European Macroseismic Scale, EMS 98. This
approach avoids the costly process in the analysis of seismic vulnerability requires site surveys for
collecting the necessary building characteristics, which often discourages the assessment of seismic
risk initiatives in moderate seismic prone regions. We validate our learning (proxy) by comparing
estimated vulnerability classes by our simple method to those actually observed on site by the
classical method Risk-UE.
For a given seismic scenario, the results give the likely damage comparable to those obtained by the
traditional method. These results are presented as histograms or risk maps using geographic
information system (GIS).

The present situation reflects a lack of experience feedback and that the memory of the effects of past disasters is not profitable at best to be able to apprehend positively the events to come.
However, the manifestations of natural hazards in Algeria confirm that many cities are directly exposed to natural hazards, earthquakes, floods, landslides such as the case of the present research applied to the wilaya of Jijel The wilaya of Jijel is characterized by a mountainous relief with strong slopes which dominates
in the North a littoral exposed to the coastal risk . The wilaya has experienced disasters that have marked the landscapes but also the memory of population, such as the 1856 tsunami, the 1928 cyclone, the 1984 floods, the forest fires of 1881 and 1983, and the impact of the advance of the sea on the urbanized coastline.
in front of this threat, what is the level of management of natural risks by the Authorities? Risk management practices in the wilaya of Jijel result in insufficient, but also constraints: the lack of available data, the insufficient of planning and urban planning instruments.
The vulnerability of the territories of the Jijel wilaya to the risks is very high through the strategic stakes such as the harbours impacted by the effects of the advance of the sea and the thermoelectric power station, while the dams are exposed to the seismic risk.
Risk management has improved considerably with the implementation of works to protect against the advance of the sea on the Kotama beach (downtown Jijel), drainage systems to limit the spread of floods in the plains.
Faced with these risks, what is the behavior of the populations? The survey conducted in the field will determine the level of perception of the inhabitants and their level of familiarity with the insurance against the effects of natural disasters (Cat Nat).

During recent decades, the area of El Ma El Abiod was marked by intense drought (erratic rainfall, higher temperatures and high evapotranspiration) also overexploitation of water reserves resulting a very significant downwash groundwater level of the Miocene tablecloth, which are the main source of food in the region; This leads to progressive desertification of the plain.
From the analysis of the current situation on the ground, this work helps to explain the operating mechanisms of the water of Miocene sands from its boundary conditions to its hydrodynamic and physicochemical characteristics, namely presence of pollutants and their sources.
This study is based on the development of an inventory of pollution sources, taking into account several factors, such as lithology land and climatic conditions, the location of discharges from sewage, farming and animal husbandry.
The vulnerability of groundwater in the plain of El Ma EL Abiod depends on the major expansion of the industrial, agricultural and urban context Despite a relative wealth of potential water resources, economic growth accompanied by industrialization, urban concentration accelerated and modernization of agriculture, led to a large increase in demand for water and therefore a high degree of pollution, monitoring degradation of water quality in the plain.
