Zoning of Tidal Facies a Prerequisite of the Integrated Coastal Zone Management of Bushehr Province (Iran)

The research objective was to identify and map the tidal zones that play a decisive role in integrated coastal zone management. Methodology designed based on the expert interpretation of the spatial boarders of the High Astronomical Tide (HAT), the spring and neap tides on the Sentinel-2A satellite images of 2018 with a spatial resolution of 10 meters to determine the risk of long-term flooding, supratidal and subtidal zones, respectively. In the coastal region of Bushehr province, an area of 81,000 hectares is subject to long-term flooding, 15,000 hectares are subject to monthly flooding, and 53.5 thousand hectares are subject to daily flooding. The results showed that up to 62% of the coasts of Bushehr province are tide-dominated coasts. Implementation of sustainable land use in the coastal region of Bushehr province is not possible without considering this risk. However, these lands are suitable for developing aquaculture, salinity, and mangrove forestry.
