“…The axes are communication, training, individual characteristics and the profile of stakeholders in the maneuver; regulatory and risk management aspects; meteorological factors that influence the maneuver; the evaluation of security at the port and the consequence of risk [14][15][16][17][18]. The analysis of the data obtained statistically using descriptive statistics and the chi-squared (X2) test that allowed us to identify the significance of the differences recorded in stakeholders' answers.…”

The present study is a continuation of our first work, which was conducted in Algerian ports, the objective of which was the management of risks related to port maneuver in Algeria. This study aims to achieve a better understanding of stakeholder's perception in the matter of port maneuver regarding the origin of risk and its consequences. This perception may be either objective or subjective. What is important is that this study reflects a reality that can enlighten experts and decision makers, thus allowing them to make specific decisions. Seventy-two stakeholders in maneuver from ten different Algerian ports have responded to our questionnaire on risk perception. The results confirmed that different parameters are at the origin of this perception.

“…During the same period prior to 1977, Hassan Gholi Bay, a large inland lagoon in north of the Gorgan delta in the Gomishan area of Iran, dried out and the coastline shifted several kilometres seaward and narrow parallel sand barriers accreted to the coast. The sand barriers subsequently breached and a new lagoon formed during the period of water level rise after 1977 (Kakroodi et al, 2012). On the whole, the Caspian Sea water level during the last two centuries has shown a long-term decline from about −22 to −28 m bgsl, with a continued decline expected because of increasing northern hemisphere temperatures (Chen et al, 2017).…”

“…Around 130 rivers flow into the Caspian Sea from the southern and western coasts which are mainly sourced from the Elborz and Caucasus Mountains. Sediments along the southern and western shorelines are mainly redistributed by wave-induced currents (Kakroodi et al, 2012;Koshinskii, 1975).…”

“…Regressions in wave-dominated facies are associated with increased density of gravitational streams on the slope, formation of alluvial fans and soil formation and deposition of loess on the coastal plain (Figure 2). During long-term regressions, deltaic progradation occurs and coastal deposits typically include low beach bars without lagoons (Kakroodi et al, 2012(Kakroodi et al, , 2015Kazancı et al, 2004;Kazancı and Gulbabazadeh, 2013;Kroonenberg et al, 2007;Svitoch et al, 2016). Deeper water facies in the middle and southern Caspian Sea show laminated sediments preserved because of rhythmic oxygenation, related to alternating relative highstands and lowstands of water level (Kuprin et al, 2002(Kuprin et al, , 2003Tudryn et al, 2014).…”

Innovative Computerized co-axial tomography (CAT)-scan methods have been applied to two short cores collected in the southern Caspian Sea, offshore from the Langarud–Rudsar region of Iran, to the east of the Sefidrud delta. Magnetic susceptibility (MS) readings, in association with other lithological criteria, are used to correlate the cores and calibrate to real time. The cores provide a sedimentary record from this largely unstudied region covering the last 200+ years (~1784 to 2008 CE). Three principal lithofacies types were recognized. The more distal locality (T2-3, water depth 117 m) consists entirely of poorly fossiliferous silty muds, whereas the more proximal locality (T2-2, water depth 51 m) contains beds with rich ostracod, gastropod and bivalve assemblages. Peak MS readings occur between ~1872 and 1918 CE and are linked to erosion of sediments deposited during the ‘Little Ice Age’ (LIA) highstands of the Caspian Sea. CAT-scan results reveal the presence of the non-marine Mermia ichnofacies type, which is reported for the first time in the Caspian Sea. Horizontal burrows (feeding structures) by Treptichnus ichnofauna coincide with periods of LIA highstand in Caspian Sea level and suggest low-energy conditions on the marine shelf. Vertical burrows (feeding structures) occur at times of relatively stable, but variable Caspian water levels. Interbedded dark coloured, organic-rich muds and lighter silt-rich layers within the last ~100 years show potential cyclicity which may be linked to climatic and/or river discharge events.

“…Recent studies calculated the coastline changes in the deltaic range of Gorgan River. He predicted the future changes of the line based on field evidences and assessing the efficiency of the methods [16][17][18][19]. They studied the coastline changes of the Caspian Sea off the coast of Iran for a period of 26 years (1975 to 2001) using MSS, TM and ETM + Landsat images.…”

Journal of Coastal Zone Management AbstractShorelines are the most important linear phenomena on earth's surface that have a dynamic nature. Thus, favorite coastal management and environmental protection towards sustainable development requires the extraction of the coastline and its changes. For this purpose, coastal zone monitoring in an appropriate time context is of great importance. As one of reliable and rather accurate sources, remote sensing data and satellite imagery in different periods are used for investigation and interpretation of shoreline changes and quantitative measurements. In this study, we tried to apply a new method to determine the shoreline changes using remote sensing and geographic information system. This method possesses simplicity and has acceptable results as well and is able to control and evaluate the results of the research process and its reliability is approved. Since the results of coastline changes are considered as the fundamental basis for analysis and other related applications, the data integrity and no other possible errors are essential. To control the accuracy of the extracted data on cross sections perpendicular to the coastline, statistical tests of sample, median absolute deviation, Z-Score and box plot was used. The results, confirms that the extracted data have no errors.
