Abstract

Various standards and criteria are existed regarding rubble mound breakwaters. Based on engineering material properties used each of them have own classification . Whereas these types of breakwaters are mainly made by rock material, knowing their engineering properties such as durability and deterioration and destruction against predominant condition in marine environments is vital in order to preparation of proper classification system. Iranian rubble mound breakwaters in Persian gulf, Oman sea and Caspian sea, are mainly designed and made based on regulations, standards and criteria of other countries such as, America, Britain, Japan and Netherland.Using of these standards caused limitations such as the mismatch of the selected stone with the given standards and operating costs are increased.This paper introduces national and international criteria in order to select rock used in break waters. In the following with concentration . on national criteria, most important indexes of these criteria presented for each type of stone.
