The waves' effects on coastal and marine activities caused to paying attention to the importance of recognizing the wave parameters using field measurements, theoretical analysis, physical and numerical modeling. In this regard, field measurements are preferred to other methods due to their precision; thus, these measured data are used for verification of other data and calibration of numerical models. Nowadays, different types of instruments are developed to measure wave parameters. These instruments record data via different mechanisms like wave buoys, ADCPs, and radars. Considering the wide variety of devices and different mechanisms of measurements, it is necessary to recognize the most appropriate mechanism and instrument regarding its accuracy. One of the appropriate and desirable methods is the crosschecked. The field measurements in the Modeling and Monitoring Studies of Iranian Coasts Project in Chabahar bay - which is located in the northern coast of Oman sea- were recorded for a short period in the same region and at the depth of approximately 25 meters using four different instruments with three measurement mechanisms (discus buoy, spherical buoy, and Acoustic Wave And Current profiler). As Chabahar is located in a specific climate situation where confronts extreme and severe phenomena such as Monsoon, strong winds, swell waves and so on, gathered data are of great importance and comparing them give us useful information on the technical procedure of the system. Despite of our expectation, the wave height has been recorded by under water sensor has been higher than other simultaneous measurements. In this respect, floating Buoys had the best performance.

Dry ports are intermodal inland terminals which have established in several countries. In the most of them there are direct and shuttle rail connections between them and one or more seaports. A wide range of all services which performed in seaports can present in dry ports such as custom clearance, storage, container stripping and stuffing, forwarding, container repair and maintenance and so on. Dry ports also act as important nodes for attracting and distributing of cargo especially containers. Regarding to general structure of dry ports in various countries, they improve and develop intermodal or multimodal transportation. In this paper, after a brief history of dry ports, intermodal transportation and containerization are investigated based on expert's point of view via questionnaires on the most important characteristics of feasibility of establishing dry ports. Finally, this analytic and comparative study is performed by means of yearly information and statistics of Iran.

Many models has been established and developed to evaluate operations in organizations. Some of these models include European Foundation for Quality Management (EFQM), Malcom Baldrige Award, and Balanced Score Card (BSC). This article has suggested a model to evaluate the operations of Imam Khomeini Port and Maritime Organization. This model is based on the Balanced Score Card model. After identifying missions and visions of the organization, this model describes the objectives of Imam Khomeini Port and Maritime Organization as well as four standpoints of BSC (financial, customer, internal process, and learning and knowledge acquisition) as the authority aspects. Then, success criteria, key performance indicators (KPI), and appropriate volume for each objective is determined. Finally, after preparing the model, its results are evaluated. Moreover, due to the developing of information technology (IT) in organizations, the obtained model is applied to Quality Performance Result Software (QPR). Using this software, all the obtained indicators are monitored and controlled automatically from various point of views. Results of evaluating the performance using QPR software caused in recognizing the processes, determining key processes, aligning processes and strategies and using the business intelligent software to monitor the measures, and implement management dashboard system.

For a long time people believed that seas and oceans are more enormous than to be polluted. But nowadays, direct and indirect effects of water pollution on the human life make it necessary to prevent from such pollutions. Pollutant sources like industrial waste water, urban waste, drainage of ballast water and vessel sewage into sea, oil spill due to the incidents of oil tankers and oil platforms, nuclear waste, natural disasters like hurricanes, dust, and volcanoes, and materials resulting from marine organisms have detrimental effects on marine ecosystems. Gradual expansion of such pollutions into coasts and islands cause fatal diseases and genetically deformations in human beings. Oil pollutions often cause negative effects on natural resources. Most of the developing countries need to protect their marine ecosystem to help tourism and fishery industries and thereby help to economic development of the country. Severity of damages result from oil pollutions depends on indexes like incident conditions and environmental conditions. Annually, more than 500 accidents lead to oil spill and therefore more than 2.5 million ton of oil outflows to the open seas. There are different methods to clean up oil pollutions. Using absorbents is one of these methods. There are three types of absorbents include natural, refined natural, and synthesis absorbents. Absorbents can also be categorized as organic, inorganic, and synthesis absorbents. But the best method to clean up the oil pollutions is using the bacteria that absorb the oil. The main focus of this article is on this method. This method is the best and only natural method to clean up the oil pollutions.
