The summary of this research is the preparation of surface drainage network map as interpreted from normal color satellite image at a scale of (1:100.000), recorded in 2001. The study area reflects the existence of different types of drainage systems such as (Dendritic, subparallel and pinnate) resulted from the differences in rock type and degree of slopes.
The gully erosion maps of study area which taken from the surface drainage network were compiled using the Surfer 8 program depending upon (Bergsma, 1982) system. The research region was affected by gully erosion and classified into three zones. Zone of slight erosion at rate of 21.17%, medium erosion zone at rate of 58.39%, and severe zone at rate of 20.44%.

Monotypic shell beds of molluscan skeletal sand are contained in the non-marine, fluvial sequence of Injana Formation of Upper Miocene age-Kand Anticline, as yet undescribed previously. These carbonate beds are characterised only by abundant pelecypod, oyster with scarce and opportunists gastropods and smooth-shelled ostracods. This faunal assemblage is consignable with non-marine low salinity euryhaline fresh, brackish water. The sudden change in their composition and distribution has been influence by salinity variation. The exclusion of normal marine-stenohaline fauna point to their deposition in non-marine setting including interchannel lake initiated on distal floodplain and/or river dominated bay esturay, or fan delta lake-lagoon.
