Introduction : One of the fundamental research for planning and development is to get knowledge on natural features of regions and awareness of their potential. Methods : In this regard, geomorphology as a science deals with landforms and features in terms of identity, material type and effective process in their evolution. It plays a fundamental role in development plans. In this thesis, the Hengam Island as an Iranian islands in the Persian Gulf which is truncated cone-shaped island located in the South coast was studied. The present research aims to assess geomorphological phenomena for Hengam Island and its role in the development tourism of this island. The study is based on field experiences and objective observations, library research and data available were analyzed in descriptive – analytic manner using software GIS 10.01. The data used in this study included maps for topography, geological, Land capability, physiography, vegetation, depth and classes, geomorphology and aspect.Conclusion : Study area has great functionality for use The landscape and with the privileges of the island High natural potential in the tourism industry The need for more accurate planning and provision of facilities.Results : The results show that morphological topography in study area both in shape and position as well as in terms of its appearance is very important so that it can have positive effects in establishing infrastructure facilities and developing geo-tourism industry in area.

This study dealt with identification and investigation of the members of Zoantharia order in tidal zones of Hengam Islands in winter 2009. To fulfill this study, five transects in five stations, Arabha, Khenezi, Abas, Ghil, and Eskele around the island were considered. More
This study dealt with identification and investigation of the members of Zoantharia order in tidal zones of Hengam Islands in winter 2009. To fulfill this study, five transects in five stations, Arabha, Khenezi, Abas, Ghil, and Eskele around the island were considered. Sampling was done in the beginning of ebb. Each transect investigated by netted quadrate 1×1m and squares 10×10 cm completely. Samples were identified according to valid references and numbers of colonies of above said stations were compared. According to the findings, 4 species of 2 families of Zoantharia order were identified in tidal zone. From percentage of species frequencies and covering point of view, results of ANOVA of stations showed significant differences (P

In this study removal of Chromium VI from aqueous solution by marine brown algae Padina borgesenni as adsorant is concerned in different batch experiments. The samples were collected by a scuba diver from Hengam Island in Persian Gulf with longitude of 26̊ and 40̋ North and latitude of 52̊ and 30̋ East in 89 Fall and transferred to the laboratory. Parameters such as the initial Chromium concentration of the solution which were 125, 250, 500, 750, 1000 ppm, respectively, and the initial pH 2, 4, 7 in 6 hours were investigated. Determination of Chromium VI was conducted by atomic absorption, VARIAN AA 240, and the statistical analysis were performed by SPSS14. Elimination of Chromium VI depended on two prominent factors, the former was the initial Chromium VI concentration and the latter was the initial pH. The maximum uptake by dried biomass of Padina borgesenni was in pH 2 and 750 ppm. This study demonstrated that the initial pH played important role in Chromium uptake by the sorbent.

In this study marine sponges of intertidal zone of Hengam Island in Persian Gulf were collected at spring low tide in desalination station in northwest of at location 55˚ 52΄ 17˝ E & 40˚ 26΄ 55˝ N (August 2009). For identifying these sponges acid digestion method and microtome section were used. All the identified sponges were from class Demospongia, 3 orders (Dictyoceratida, Hadromerida, Haplosclerida,) and 6 families (Suberitidae, Clionidae, Callyspongiidae, Chalinidae, Niphatidae, Spongiidae), and revealed six genera from Desalination Station: Callyspongia sp.Gelliodes fibrosa, Haliclona sp. Cliona dioryssa, Pseudosuberites mollis and Spongia officinalis. This Research is the first study to identify sponges of this Iranian islands based on microtome sectioning of their skeletal structures.

The Scleractinian corals have largest diversity in the marine ecosystem. The corallites of corals often used to identify the Scleractinian corals. This survey was conducted in spring 2012, aimed to determine species diversity of Scleractinia corals off Hengam Island located in northeast of the Persian Gulf, Iran. The distribution patterns and health statuses were determined using Manta Tow method. Thereafter, the collected coral specimens were identified to the species level. The best living hard coral cover was found at the depths between 3 to 6 meters and Faviidae corals were the dominant hard corals around the island. There are at least 33 of Scleractinian corals belonging to 21 genus and 8 Families. Fishes especially of ornamental specieswere frequent in the waters surrounding this island.
