About the project

Hormozgan province covering an area of 71,193 sq.km. is located in south of Iran and north of Persian Gulf. The southern province of Hormozgan is located between latitudes 52- 40` and 59- 15` N. and longitudes 25- 26` and 27- 19` E. It is bounded on most parts of its north and northeast by Kerman province, on the northwest and the west by Fars province and Bushehr province, on the southeast, by Sistan va Balouchestan province and on the south, by the azure waters of the Persian Gulf and the Oman Sea. The strategic Strait of Hormuz, one of the today most sensitive and vital waterways and also by far the world’s most critical oil traffic chokepoint, is situated in political realm of this province. Bandar-Abbas, Bandar-Lengeh, Minaab, Roodan, Qeshm, Jask, Haji-Abad, and Abou-Mousa constitute the townships of this province.

نقشه ایران

Daily economical growth and increase in coastal applications has necessitated precise identification of coastal phenomena and performing contemporary studies in coastal zones. But the nature of marine phenomena makes these identifications and studies unreachable without having field measurement data.
Therefore absence of sufficient information and field data may result in an insufficient knowledge of negative effects of these phenomena on coastal structures and a decrease in marine structure's life due to harmful hydrodynamical and geomorphological interactions.
The Ports and Maritime Organization as one of the major authorities in coasts and marine affairs has defined monitoring and modeling studies of Iranian coasts to perform its responsibilities, update the previous projects and in continuation of previous studies like measurement of marine parameters, modeling of Iranian sea waves and Integrated Coastal Zone Management.
Monitoring and Modeling Studies of Hormozgan Province project was defined as to study the coasts of this important province and also to transform achieved data to numerical models in order to investigate coastal behavior and predict the future of these coasts. PMO is performing these studies in cooperation with Fara Darya Arsheh Consultants from Iran and SOGREAH consultants from France, along with Darya Negar Pars Consultants who is in charge of field measurement operations. This project has been started from February 2009 and is set to be finished within two years.
 
Study Outlines
Different studies like extensive field measurement, numerical modeling, wind model and etc has been considered in monitoring and modeling studies of Hormozgan Province, therefore this project is a crucial step forward to study the coastal evolution of the region.
 
Objectives
  • Gathering and reviewing available data and reports related to aims and targets of the project.
  • Continuous measurement and analysis of met-ocean parameters such as water level, wave height, wave period, current speed and direction, wind speed and direction, suspended sediment particles, and bed sediment material in the study area for maximum one year period.
  • Mathematical simulation studies of hydrodynamic phenomena in the study area due to tide, wind and waves.
  • Evaluating the existing coastal engineering problems around hot spots within the study area as mentioned in the scope of services of the contract.
  • Specifying the design wave characteristics for various return periods up to 100 years in the study area particularly, close to coastal structures and hot spots.
  • Classifying the coastal area of the Hormozgan province based on morphological and coastal engineering point of views
  • Preparing a long term monitoring plan for the coastlines of the study area considering the coastal engineering point of view.
  • Evaluating the change of coast line in the study area
  • Upgrading and updating the wave characteristics in the study area.
  • Evaluating the Iranian Seas Wave Modeling (ISWM) in the study area.
  • Creating a data base for the gathered and measured met-ocean data and other related geographical based information.

Data Gathering
In order to have comprehensive recognition of the study area and to perform monitoring studies, gathering immense data for different themes like hydrography, topography, wind, wave, current, geomorphology and etc. is necessary. These data will be used as inputs for modeling phase which is one the most essential parts of the project.
A brief list of data to be gathered will be as follows:
  • Gathering and analysis of wind fields (ECMWF, ERA40 & WRF)
  • Analysis and evaluation of every performed studies in the area (sediment, wave …)
  • Gathering and analysis of ISWM wind and wave data along with ICZM studies and previous monitoring projects
  • Gathering and evaluating hydrographical, topographical and geological maps
  • Gathering and evaluating every data related to ports and marine structures
  • Gathering and evaluating aerial and satellite images necessary for performing the studies
  • Preparing working areas for performing extra surveying
  • Preparing hydrographical maps
Field Measurement
Today, the monitoring and modeling studies in Hormozgan Province is one of the largest field measurement projects in Iran and also in the Persian Gulf and Oman Sea region.
Because of the immense extent of studying area which contains a big part of Oman Sea and an important area of Persian Gulf, the amount of foreseen field measurements is widely spread and contains various parameters like wave, tide, current, meteorology, sediment and temperature, saltines, density, … profiles.
The most important measurements which are going to be performed in the project are:
  • Offshore wave and current measurement in 25 meters depth by 3 stations for one year long
  • Wave and current measurement in surf zone by using 2 short-term different stations along the coast for one year long
  • Wave and current measurement out of surf zone by using 2 short-term different stations along the coast for one year long
  • Current measuring near Gheshm island and important marine structures by using 2 stations
  • Tide measurement by using 7 stations for one year long
  • Measuring meteorological parameters in 3 stations for one year long
  • Sampling 920 sediment samples and photographing from the corresponding region
  • Performing 25 hour measurement in 6 stations in two seasons
  • Surveying coastal profiles near important structures up to suitable depth
  • Sediment trapping near three structures for one week long in a calm and a stormy season

Numerical Modeling
In order to achieve the monitoring and modeling project goals and use them in future plans, recognition of sediment and hydrodynamic phenomena by using numerical models is of considerable importance. Although field measurement in the project area is widely extended and do include various parameters, but the large extent of project area, make field measurements in more points impossible and limited. Whilst performing these activities in such an extent for longer period needs abundant expenses.
Therefore numerical models can be used as a comprehensive tool to simulate the hydrodynamic behavior of the sea and its interactions with the coastal zones in the study area for long period. In the present project, performing numerical models is foreseen in the following items:
  • Extending the Iranian Seas Wave Modeling (ISWM) in the study area for at least 25 years 
  • Local wave dispersion modeling in specific regions determined by client
  • Modeling wave influence in port basins of study area
  • Modeling of mean water level fluctuations (storm surges and wave set-up)
  • Tidal modeling
  • Global current modeling
  • Current modeling in shallow waters along coastline
  • Three dimensional modeling
  • Sediment transport and morphology modeling
  • Coastal flood modeling
  • Investigating and scrutinizing the Iranian mathematical models.
