The study team, visited the site of the project and geomorphologic evaluation of marine and ground medias were implemented. Doctor Risk from Braid company in Canada met local geologists and marine biologists during the ground visit. He revised the previous reports and evaluated the present marine condition emphasizing specially on beach sediment sources.

The following results were obtained due to the site visit:
The main sediments source in the study shores, is the beach cliffs erosion which is usually formed of red sand stone covering green silt stones with sand. The common sediments in the beaches of the area shown to be of two main types of sediment generating sources in Chabhar bay which are red sand stones and rather green silt stones with a mixture of local carbonate and organic materials.
The beach redish sands have been put in order which has an average size of (0.3-0.5 mm) and made of quartz and consists of variable carbonate values. The carbonate materials source can be marine reefs in south east part of the bay (according to the diving observations), or bivalve aynfrnal animates, or Gastropods apyfonal mollusks, and Foramynyfrans. Some intact remains of shells are found in the high tidal levels which have been remained by storms. Minor minerals in these veins conclude Narsang, Magnetit, Feldspar and probably Orthoclase. The red color of these veins are due to Iron oxide color in addition to pink Feldspar.
Intact crusts from mollusks remains in the beach area. The crusts have been remained of Oysters, Olive tree, limatolids and rock Oysters. These materials have been carried by the sea through the beach. This is because there is no scratches on them.
The greenish silt sand have fine grains. This point is also true for carbonate grains and most of the underlyings. Rainfall seldom happens in these shores and is scattered, but raining usually cause great river discharge and irregular fine sediment entering to the river from high lands. It seems that sediments move from south toward north in both sides of Chabahar bay. In northern beach of the bay, the beach sand is lifted by powerful winds which blow from the sea and spreads into the land in a shape of dunes.
