Iranian coastlines have been rapidly developing over the past three decades and many new or expansion port projects in oil, trade and fishery sectors are currently underway. Using coastal areas for recreational, social and environmental activities is also expected to grow in the near future. It is, therefore, very important for the country to put a coastal management program in place to optimize the use of its coastal resources and prevent or minimize the impact of various projects. As one of the organizations in charge of Iranian coastlines, the Ports and Maritime Organization (PMO) has taken the lead to initiate a number of basic studies which could support and provide information for local shoreline management issues including erosion, sedimentation, wave agitation, navigation, water quality and future plans. In this line, PMO has previously introduced the Integrated Coastal Zone Management (ICZM) project and the Iranian Trade Port Master Plan project.
The success of the above projects and any other future coastal development depends on availability of basic information on environmental parameters such as winds, wave climate, currents, tides, sediments, geomorphology and bathymetry. In this regard PMO took the first step by introducing the Iranian Seas Wave Modeling (ISWM) project to define the wave climate along Iranian coastlines. The present series of monitoring and modeling projects is considered as a further step toward understanding coastal zone processes and providing basic information for future projects and coastal development plans.
This project involves various tasks including extensive field measurement, mathematical modeling, development of an Iranian wave and hydrodynamic model and recognition of issues relating to the country's coasts with the follows objectives:
1- Preparing and providing Morphologic and Hydrodynamic information to use in the ICZM project which is under consideration by the Ports & Maritime Organization's general directorate of ports and coastal engineering.
2- Examining the existing problems in the subject coastal zone and presenting solutions from the coastal engineering viewpoint.
3- Gaining access to a trustworthy data reference in order to use in the research and planning of the coastal and extra coastal structures in the subject zone.
4- Completion of the integrated plan of the optimum network of field specifications measurement in the country's north & south waters.
5- Improve and making the modeling results of the south sea-waves precise.
6- Preparation and development of a reliable Iranian model in order to use the mathematical simulation of the hydrodynamic parameters and the sedimentation in the country's waters.
7- Precise examination of the coastal line alterations in the subject zone for the country's future planning.
Significance of the study
Regarding the issue that the coastal environment's potentials are going to be discovered more and more in different ecological, social and recreational fields, it is predicted that in the future the new activities with a more extensive volume are going to be implemented in these areas. To make the best use of this broad stretch of land, there needs to be an appropriate, compiled plan set in place and the implementation of the right management. The complexities ruling the way of interaction between the land (terrestrial environment) and the sea (marine/aquatic environment) are the result of nature and the special characteristic of each of these two environments. As well as human interference making use of this broad land, makes gaining access to such a compiled plan very difficult. One of the decisive elements in gaining access to this plan is to collect sufficient data on the Hydrodynamic regime and the zone sedimentation and to have an appropriate understanding of the alterations caused by different factors on the Geomorphologic specifications which, unfortunately, most of the time is not accessible because of the lack of sufficient data.
Issues and range of the studies
Second phase of the project which will be implemented in Naiband to Dayer bay reach, is based on the national plan of monitoring and simulation studies of Iran coasts. This phase has been started siace 2008. After equipping the workshop and doing the primary jobs for starting the measurement operation in this area, taking the marine measurement data concluding sediment, flow, wave, etc. has been started since Augest 2008 and still is going on. The modeling relevant to this phase, has been started since January 2009 and after the project owner notification. The following figure shows the study area of the project second phase.

This national project has been defined by the manager and experts of the Ports & Maritime Organization’s general directorate of Ports and Coastal Engineering and in direction of PMO’s general objectives. Also, in order to precisely supervise the project’s best performance a specialized committee with 8 experienced and famous Iranian experts in different fields, cooperate with this department.
