Sedimentation in ports (enclosed with breakwaters) is one of the problems in these coastal basins. In order to solve this problem and to secure the navigation, dredging operations must be done continuously. However, in designing these ports, expedients can be carried out instead of dredging operation with high annual costs to prevent the influx of sediments into the harbor remarkably. The aim of this study is to investigate the effect of the western and eastern breakwaters development plan in Anzali Port on the basin and to exactly identify the hydrodynamics and sedimentation processes using field measurements, numerical simulation, and analysis of wave penetration into the port basin at the conditions before and after breakwaters development. In this paper, the changes of wave and current patterns due to construction of the new breakwaters are investigated using MIKE 21.3 Coupled Model FM model and it has been tried to use the updated data for modules and to deploy minimum simplifications regarding the region modeling. For this purpose, an area of ten kilometers along the coast and nine kilometers perpendicular to the coastline have been selected as the computational domain and after running a regional numerical model for different scenarios of wind direction and speed, the boundary conditions for local model are extracted from the regional model. The simulated numerical results show that construction of new breakwaters actually trapped some of the sediment particles which have naturally entered to the sea before construction of them. In other words, the extended part of the port acts as a sedimentation trap.

Land allocation strategy in port areas usually leads to defining services and productive activities in a broad scale but it will not end in providing an optimum plan for a set of industries of a certain classification. Obtaining the major objectives of each port in the scope of revenues or competitions depends on optimal selection of proposals suggested by the investors. Otherwise, these valuable lands will be allocated to set of activities which will not lead to elevation of the port competitive power. Assuming that the major strategy of a port is to provide warehousing services, the present research investigates allocation of hinterlands based on the performance criteria, evaluation and prioritization of competing items using the multi-criteria decision-making methods such as Analytical Hierarchy Process (AHP). The results reveal that land allocation for container terminal construction is at the first place (0.64 %), warehouse construction is at the second place (0.25%), and silo construction is at the third place (0.11%). Accordingly, the proposals which can present the most economic advantages for port will be singled out as the best proposal.

The purpose of the present research is to investigate the role of marketing mix, especially serivice factor in ports marketing, to identify the most important factors affecting customers satisfaction (shipping, owners and forwarders) from services in Imam Khomeini Port, to prioritize the factors affecting customers satisfaction in port industry, and to provide suggestions for designing services in compliance with customers' need in two stages. At first, twenty nine indicators were defined as independent variables based on customer satisfaction forms and supervisors comments. Then, these indicators were put into Kano questionnaire. After the above mentioned stages in Kano model and considering the type of each of the factors, the customer satisfaction index is calculated. In the second stage, the role of marketing mix in customer satisfaction from port services in Imam Khomeini Port are investigated. The hypothesis test revealed that 8Ps marketing mix have efficient role in customers satisfaction from port services in Imam Khomeini Port. The results of 8Ps prioritizing show that the services have the first place, the price and other port costs have the second place, and the location and time have the third stages.

Determination of wave characteristics, including height and period, are the primary steps in coastal and offshore engineering studies. In technical literature, various wave forecasting methods have been suggested and developed gradually. Some of them are based on experimental and observational methods; the best example is Beaufort scale. Some other methods are based on dimensional analysis such as SMB and SPM methods, and some are based on mathematical models which apply numerical solution of energy diffusion equation. Up to now, three generations of wave forecasting numerical models have been presented, which the nonlinear interaction of wave parameters are ignored in the first generation models. In the second generation models, these effects are modeled, but some restricting hypotheses are applied which these bugs have been fixed in the third generation models. So, the third generation models have been developed with this purpose. In the present research, the SW module of MIKE 21 has been applied. MIKE 21 is a third generation numerical model which measures the wave due to wind field on the sea surface. The main entries of such models of wave forecasting are wind and wind field parameters. In this regard, several models have been developed; an example is the developed model of European Center for Medium Range Weather Forecasting (ECMWF). Using the QuikSCAT Satellite and ECMWF data, the wave characteristics are hindcasted in the Persian Gulf and compared through buoy measurements.

The purpose of the present research is to investigate the feasibility of investment on second port construction in Nowshahr Port. Using the financial models, the IRR and NPV indices and the payback period are analyzed based on the main criteria of minimum annual performance in various scenarios of the rate of the second terminal performance growth. The research variables are analyzed through Comfar Software. Among the 6 predicted scenarios, the investment was justifiable in three scenarios which give the investor an opportunity to investigate the factors affecting the second terminal project in Nowshahr port. This research is conducted during 2010- 2011 and cost and benefit variables are based on the monetary rate on the same years.

Considering that providing required loading and unloading services is of high importance, especially in competition among ports, defining appropriate criteria and applying an appropriate method for evaluation and selection of companies providing these services would be one of the priorities and necessities for port authorities. In the present article, the multi- criteria decision- making method is applied for evaluation and selection of port contractors. Six questionnaires were applied, three of which were to define the selection criteria, two of them were to determine the weighting of criteria, and one of them was to collect the applicants' data. After data collection and applying AHP method, three criteria were selected which are: »corporate and financial profile of applicants«, »the capacity of investment on facilities, equipment and systems«, and »facilities action plan«. On the other hand, considering that the compatibility ratio of the entire paired comparison matrices is less than 0.1, the reliability is approved.

Today, the banking matters are done in the simplest way through E-commerce. The organizations are obliged to apply electronic banking services and promote their service quality. Hence, there is a need to investigate the barriers to E-pay of income. The purpose of the present research is to identify the barrier to applying the E-pay in receiving the income of Ports and Maritime Administration of Sistan and Baluchistan Province. The population of the research includes 380 of employees and managers of Ports and Maritime Administration of Sistan and Baluchistan Province. The sample size was determined using Morgan table, based on which 200 questionnaire were distributed by simple randomized method. Ultimately, 186 questionnaires were filled and analyzed. A researcher-made questionnaire was used to collect data. To analyze the obtained data, SPSS software and Chi-square and Friedman tests were applied. The results reveal that barriers to using E-pay in PMO income are: technical characteristics of the network, shortage in skilled manpower, characteristics of E-pay system, characteristics of financial rules and regulations, and characteristics of PMO financial system.

One of the most discussed potentials related to renewable and eco-friendly energies is using tidal currents energy. Extraction of energy from tide is practical in places where much energy is focused as big tides and the geographic situation provide an appropriate site for tidal power plant construction. Considering that more than 5000 MW renewable energy power plants are to be constructed in Iran during the Fifth Development Plan, identifying appropriate sites for this purpose and evaluation of renewable energies in these sites is of high importance. In the present research, the feasibility of energy extraction from tidal currents in this region is investigated considering the geometric characteristics of Qeshm channel and the strong tidal currents in this region. The other issue studied in this research is applying operational methods and not merely scientific methods of energy extraction based on the latest results and guidelines of European Marine Energy Centre and tidal currents modeling. Based on the research results, 1850 W renewable energy was estimated extractable from tidal current. The extractability of this size of energy has encouraged many governments around the world to extract and use this energy. The result also reveals that merely using the APD criteria which is the basis of judgments in many studies is a flawed and impractical basis.

Chromium (VI) is one of the heavy metals and water resources pollutants which is in industrial wastewater, including electroplating, tanning, dyeing, textile manufacturing, mining and fertilizer industries. Activated carbon with nano pores is a green technology for separation of poisonous material in environment. Given the hazardous properties of the metal, its removal by an effective and environmentally friendly method, is necessary. The aim of this research is to determine the level of Chromium absorption by activated carbon of almond- shell in concentration of "20", "50" and "100" per part million (ppm) and different insolubility times from "15 to 120" min. Experiments for determining isotherms were assigned discontinuous in different concentrations and different amounts of biological activated carbon (from "0.1 to 0.3" gr) and the Chromium with desired PH. Measurement of Chromium performed by atomic absorption device and based on the standards. Observing the research results and the PH regulated on "6", increase in primary concentration of Chromium resulted in increasing of absorption level and also by elapsing the time, absorption level was raised and the maximum absorption on "69.7%" was happened in time range of "120" min. The results indicate that bio absorber containing sodium alginate containing activated carbon prepared from almond shell is new adsorbent for the removal of chromium ions from aqueous environments.
