Résumé :
This study attempts to assess the role of basin morphometric parameters in slope instability using a morphometric diversity (MD) model, as well as the role of drainage parameters and relief parameters in slope failure using drainage diversity (DD) and relief diversity (RD) models, respectively. For this, a total of 14 morphometric data layers were considered. The relationship of each data layer to landslide susceptibility was judged using a frequency ratio (FR) approach. Parameters like drainage density (Dd), drainage frequency (Df), relative relief (Rr), drainage texture (Dt), junction frequency (Jf), infiltration number (In), ruggedness index (Ri), dissection index (Di), elevation (E), slope (S), relief ratio (Rra) and hypsometric integral (Hi) were positively related with landslide potentiality while bifurcation ratio (Rb) and drainage intensity (Din) negatively correlated with S failure. The principal component analysis (PCA)-based weight assigned to each data layer in each model was multiplied with unidirectional reclassified data layers for each model using a weighted linear combination (WLC) approach to prepare landslide susceptibility maps. The receiver operating characteristics curve showed that the landslide prediction accuracy of the DD, RD and MD models were 71.4%, 73.9% and 76.3%, respectively. The FR plots of the aforesaid three models suggested that the chance of landslide increases from very low to very high in susceptible zones.

Résumé :
Ayvalıtohma Stream Basin is the sub-basin of Tohma Stream, which is one of the western branches of the Euphrates River. The geomorphological features of the study area between Darende- Hekimhan (Malatya) Gürün and Kangal (Sivas) were determined within the framework of field studies and geomorphological analyzes on synthetic surfaces. The study area generally consists of plateaus between Uzunyayla Plateau and Malatya Basin and deeply disssected by streams. The narrow and is deeply gorge and canyon valleys opened by Ayvalıtohma Stream connect Uzunyayla, Ayvalı-Kuluncak, Darende-Balaban depressions. These gorges and canyons, which are typically seen around Gürun, Darende, Kuluncak and buried in the karstic foundation, played an important role in the formation of the flood plains along the Ayvalıtohma Stream. The Ayvalı-Kuluncak Depression, which forms the center of the study area, has the characteristics of an intermountain basin developed in the Oligocene. Detrital deposits such as conglomerate, sandstone and mudstone, which were deposited in the Oligocene and had low erosion resistance, revealed the areas that suffered the most erosion in the basin. While these non-resistance rocks cause erosion, the thick limestones in the mountainous and plateau areas have led to the development of relatively macro karst forms, especially between the elevation of 1700-2100 m.

Résumé :
Floods are one of the most recognized natural hazards that create havoc in society. Flooding involves inundation of a huge tract of area under water owing to heavy rainfall. The occurrence of flooding lays a severe impact upon the agricultural sector. The Balason River basin in Darjeeling district of West Bengal is not an exception in this regard. The basin is one of the most flood-prone areas and involves a lot of loss in crop production and destruction of villages. The present study aims to identify the flood susceptible zones of the district through the application of analytical hierarchy process and geospatial techniques, and also makes an attempt to detect how much settlements and croplands fall within the high susceptible flood prone area so that proper precautionary measures can be taken to minimize the maximum damage.
