The Lake Paliastomi is located in the extreme western part of Kolkhety Valley bordering the Black Sea coastal area.The paper deals with the analyses of the materials collected through the field and theoretical studies prove, that the natural landscapes of Paliastomi and its neighbouring wetlands were the subject of the strong impact of anthropogenic factors.

The Makran coast of Iran is exposed to the long waves generated in the Indian Ocean. The coast experienced huge waves induced by tsunami and cyclone during the past decades. Using the impact of the past events we present potential inundation areas for the great waves on the Makran coast. Based on the value of long wave height, three flood zones are specified on the inundation map. The first zone associated with no considerable inundation on uplifted rocky shore, the second zone would experience up to a few kilomet...

Surface and core sediment samples from the Iranian continental shelf of the Gulf of Oman have been studied using standard sedimentological techniques. Based on the grain size analysis of surface and core sediments, the silt fraction is the common sediment type in the Makran shelf. It ranges from 40\% up to 76\%. The amount of clay fraction varies from 19\% to 54\%. Sandy sediments appear in some cores up to 20\%. Mean content of organic matter and calcium carbonate in the sediments is around 1.75\% and 15.4\%, res...
