Resumo

Algeria is classified as a semi-arid to arid zone due to the importance of evapotranspiration compared to precipitation. This study presents a summary of experimental results on an unsaturated soil in the Biskra region classified as an arid zone. The behavior of soils in these regions is somewhat unique and evolving. The soils in the Biskra region are distinguished by their geomorphological position and origin, as well as their water regime. They share particular characteristics such as unstable structure often in honeycomb shape, heterogeneity, large porosities, and good surface aeration. It should be noted that the rise of groundwater has continued to shape the urban landscape of the Biskra Valley. The mode of accumulation of soil deposits seems to be mainly responsible for the formation of an open and metastable structure, which is susceptible to collapse. The objective of understanding the effect of lineaments is to be able to better characterize the structure of the soil in this region

The study's primary goal is to locate regions in Biskra region that are prone to soil collapse by combining Remote Sensing and geographical information system (GIS) methods. To create thematic maps such as geology, geomorphology, lineament and lineament density, drainage, drainage density, and slope maps, the researchers employed FCC Image of Landsat TM 30 m resolution data and topographic maps. Several geomorphic units were identified through this process.
