The Albian- Cenomanian (Kazhdumi Formation) sediments from northeast of Shiraz, Zagros Basin, represents a carbonate sedimentary succession and contain diverse gastropods and bivalves. Detailed studies on 80 samples of invertebrate macrofauna on two stratigraphic sections led to recognized 2 species and 5 genera of gastropods and 7 species and 13 genera of bivalves assemblages. The abscence of ...

Abstract Wadi Aidib lie at southern part of the Eastern Desert Egypt, between 22° 15’ - 21’ N and Longitudes 36° 20’ 30’ E, covering an area about 30km2. It is covered by basement rocks dissected several wadies, as a main wadi with tributaries.

Reservoirs overflow during flood season because of sedimentation cycles, which severely affects their effectiveness. Siltation is a major problem in dams constructed waterways arid and semi-arid areas. Therefore, the reservoirs wadis lose capacity due to sedimentation. This study determines an optimal design trapping basin on steep slope areas for Wadi Bishah Asir region southwestern Saudi Arab...
