Investigation a Coastal Park in Coastal zone of the Karoon River, Iran

The objectives of river improvement tasks are to aid navigation to prevent flooding to reclaim and protect land to provide water supply for irrigation, hydropower development or domestic and industrial use. Shoushtar is a coastal city that includes a big part of the Karoon river and has many water applications; so, the crevasse canal of the Gar-Gar is an artificial and manmade branch of the Karoon (the biggest river in Iran). Study of flows and sediments deby in this area associated to the centrifugal force has significant importance. As a result of effecting centrifugal force in meander of river, there are different sediments deby and currents model to produce eddy or whirlpool structure so the coastal line destruction in this coastal line and width of river would be extended. Studying water currents in different basins such as rivers, straits and bays have been important as a result of valuable matters in scientific features. When a canal of water current is direct without any in turn directivity, water body moves calmly, only a mild damping rate in time and space. Coastal parks are influenced by coastal sedimentation as a result of water currents and so, coastal water erosion should be studied to decrease its rate to some extent is possible. In this paper following an annual research project, we consider benefits of such this park and where it would be better built. Study and development of civil engineering and structure architecture are important using improved water resources to being efficient in life and progressing industry, agriculture and production too.
