Abstract: The area investigated covers Khor AL-Subiyah inlet which is one of the most important and sensitive area in Kuwait because it is connected between Shatt Al-Arab rivers and Kuwait Bay, close to many anthropogenic activities and also close to Bubiyan Island where many activities occur nearby. The tidal inlet within and around Bubiyan Island is dominated by tidal currents and the accumulation of soft mud that is well seen within the intertidal flat. Mudflats with increasing number of burrowers make up most of the beaches in the western part of Bubiyan Island. The middle parts of the tidal inlets are formed of coarse suspended sediments reflecting strong bottom currents. Suspended sediments are commonly observed in the inlets. Benthic communities as well as large quantities of foraminifera are well documented in the main inlet. The benthic communities are affected by the inlets salinity accordingly they vary from one place to another. The objective of the study is to assess the impact of anthropogenic activities on water quality and sediment. During the study water samples were analyzed for phisco-chemical parameters such as: Temperature, Salinity, Hydrogen Exponent (PH) and Dissolved Oxygen (DO) and sediment samples were analyzed for: Grain seize Analysis and Geochemical Analyses such as: Total Petroleum Hydrocarbons (TPH), Trace Metals (TM), Total Organic Carbon (TOC) and Nutrients. We found that the area is moderately to heavily polluted when compared with KEPA permissible standards. The study identified formation of abundant anthropogenic deposits at the western and northeastern parts of the tidal channel of Bubiyan Island. Sediment distribution varied between soft mud to muddy sand along the tidal channels. Tidal currents, trending north to south, affect most of the sediment distribution. The coastal dunes and rocky tidal flats are found at the southern part of the main entrance of Khor Al-Subiyah, while soft sediment form the northern most part of the Khor. The coastal geomorphic features are highly affected by v the tidal current as well as wind action. It is found that the level of pollution is higher at the southern part of khor Al-Subiyah. The study highly recommends the following: (1) Identify and understand the effects of coastal development on the tidal channel (Khor Al-Subiyah) habitats, (2) evaluate the use of tidal channel as early warning system for pollutants and (3) conduct intensive studies for assessing the harmful chemicals in sediments and shellfish.
