In order to determine the source and critical areas of wind Erosion, Sistan Plain, IRIFR-E.A method was applied. According to geomorphological investigations, the studied area consists of the following two main units namely: Pediment with 1 type and 8 geomorphological facies, and playa with 2 types of flatland and desert type that includes 9 geomorphological facies. On the basis of sediment, th...

Summary: Half a century after the work of prehistorian G. Camps on “Iberomaurusian” site Rachgoun, located northwest coast Algeria, nothing has come to confirm, supplement or revisit conclusions this author, which still remain in force. In 2017, interest deposit was revived, with view relaunching prehistoric research Algerian north-west (Oran). contribution, we have approached subject, from geo...

Geomorphology affects the potential of land. The geomorphological condition an area has implications for physical characteristics, including: 1) type; 2) material; and 3) processes formed upon it. Understanding land capability allows evaluation suitability. Classification suitability is carried out by combining results identification with requirements plant growth or existing use. Evaluation ca...

Slope units represent surface slopes by means of polygons delimited drainage and divide lines obtained on a digital topography. Objective slope unit delineation for given elevation model is still an open issue and, often, limitation that may dictate the use more traditional pixel-based approach spatial analysis. Availability maps facilitates many kinds studies allows scholars to focus specific ...

The Ethiopian region records about one billion years of geological history. The first event was the closure of the Mozambique ocean between West and East Gondwana with the development of the Ethiopian basement ranging in age from 880 to 550 Ma. This folded and tilted Proterozoic basement underwent intense erosion, which lasted one hundred million years, and destroyed any relief of the Precambri...

This study analyzes multi-temporal LiDAR data of high accuracy and high resolution by installing a geomorphometric model for extracting landslides. First, two sets of LiDAR data were acquired for before and after a heavy rainfall event. The landslides which took place from 2005 to 2009 were classified automatically by satellite images, and subsequently the landslides were interpreted and edited...
