At early 90's, Ports and Maritime Organization has launched various research projects in the field of marine parameters monitoring and modeling in order to satisfy the need of having a comprehensive database as an authorized organization.

Using mathematical simulation for hydrodynamic phenomenon, sedimentation and hydrography along with equipping ports and coastal area with site measurement systems (permanent and temporary) were the main parts of this process, which are explained in details in the following paragraphs.

a) Marine Parameters Database:

1. Wave buoys: a significant number of wave buoys were installed at Caspian Sea, Persian Gulf and Oman Sea in order to measure meteorology (wind velocity and direction, temperature, relative humidity, and air pressure) and oceanography (wave, salinity and water temperature) data. 

2. Water level flocculation: a number of stations were utilized to measure tide variation at northern and southern ports.

b) Iranian Sea Wave Modeling (ISWM):
In this research Iranian sea waves for duration of 12 years were modeled using Mike 21. The wave rose were derived from wind data (simulated by ECMWF).

c) Monitoring and Modeling of Iranian Coasts:
 Sustainable developments in accordance with political, economic and social goals are going to be the final achievements of this plan. 

The main objectives of this project are as follows:

1. Gathering hydrodynamic and morphological data to be used in the integrated coastal zone management plan of the Iran (ICZM), the Iranian commercial ports master plan, tourism along the coasts, discern of codes and standards of marine construction, and coastal land use.

2. Observing the existing problems in studied coastal areas and provision of engineering solutions to solve these problems.

3. Achieving a reliable source of information to be used in studying and designing coastal and offshore structures in the studied regions.

4. Completing the comprehensive plan of the optimized network of marine parameters measured in the northern and southern waters.

d) PMO Dynamics:
 Persian Model for Ocean Dynamics is an Iranian numerical model developed for coastal engineering studies by Iranian experts. The growing need to a coastal engineering software and dealing with difficulties such as lack of technical knowledge transfer, and considering the need to a valid native numerical model, the Ports & Maritime Organization (PMO) decided to invest in development of this model. 

This model is applicable in various fields of coastal engineering. It can simulate in tidal currents, wind-driven currents, Coriolis induced currents, currents in large scale environments (oceans), wave-generated currents. Also, this model can be applied for large and small scale wave generation and wave propagation simulations, coastal morphology, sediment transportation and finally tidal analysis and tidal parameters extraction.

e) Iranian Integrated Coastal Zone Management:
 IRICZM is a dynamic, integrated and evolutionary program which aims to strike a balance between the conflicting interests of different parties in coastal zone on the basis of coastal ecological capabilities and long-term developmental needs.



Integrated Coastal Zone Management



Based on the need for improving maritime safety at territorial waters of Islamic Republic of Iran, the growing trend for rehabilitation, construction and development of marine structures, maritime transport (shipping) expansion, the attempt for optimal utilization of marine resources at Persian Gulf, Oman Sea, Hormuz Straight and Caspian Sea,  the importance and variety of coastal areas' activities and high costs of these activities at national and international levels, mathematical simulation of waves and currents would be of great importance. 

Considering the above mentioned issues, in line with obligations of this general directorate, and the statue of Port and Maritime Organization as a marine reference and in order to help localization and independence of consulting engineers, researchers and experts from foreign software, due to the prescribed limitations, this general directorate started developing PMODynamics with cooperation of a group of experts in the form of Iranian coasts monitoring and modeling studies.

PMODynamics, Persian Model for Ocean Dynamics, is an Iranian 2D numerical model developed for Coastal Engineering and Physical Oceanography studies. The growing need to local marine engineering software, able to deal with difficulties of using commercial software led to developing this national model.

The Model is applicable in different fields of Coastal Engineering and Physical Oceanography. It can perform simulations in tidal currents, wind-driven currents, and Coriolis induced currents. It can also simulate current generation in large scale environments (oceans), wave-currents interaction, large and small scale wave generation, wave propagation simulations, coastal morphology, sediment transportation and finally tidal analysis and tidal parameters extraction.

After developing and releasing the first version, the model has been supported by a team of developers.  During the first and second supporting periods, most of the problems and bugs which were reported by users were solved by the developers. Right after the initial release of the model, a free version was uploaded on the PMODynamics official website (http://pmodynamics.pmo.ir/)

PMODynamics is now available in public and professional versions. The only difference between the two versions is that coupled wave and current simulations can only be performed in the professional one. 

After Registration at the website, the public version is downloadable for all applicants but in order to apply for the professional version, a request should be sent to CPED@pmo.ir.

Required information and news about the software is available on the website. So, users can ask their questions, report software bugs, or send their comments via the website.

Ports and Maritime Organization is responsible for design of coastal structures regulations, so a new national guideline for coastal structures design has developed   In order to control and manage the maritime constructions.

The guideline create synchronization and standardization in the criteria for design, construction, supervision and implementation of coastal structures , as well as the principles, methods and technologies that suit the equipment and national  conditions.  Although using national standards, according to some limitations t in some cases, international standards have been used in guideline.
