Prediction of Coastal Wave Height using Hybrid-Wavelet Methods Artificial Intelligence (Case study: Amirabad Port the Caspian Sea)
In this article, the accuracy of empirical and numerical methods in prediction of wind wave characteristics in AmirAbad and Bushehr Ports have been studied, evaluated and compared. First, the wave characteristics have been calculated using Babolsar and Bushehr synoptic stations and employing empirical methods including SMB, SPM and CEM. Moreover the errors of empirical methods have been determi...
The process of erosion and desertification affects social communities, agricultural lands and natural resources in coastal areas. The rapid coastline changes would cause social and economic issues in the coastal areas. In this study, Miankaleh coasts and the eastern coastlines of Amirabad port have been surveyed due to existing benchmarks since June 2013 until December 2015 in order to analyze ...
This study was conducted to investigate morphometric variation and differentiation in common kilka (Clupeonella cultriventris) caught from Amir Abad and Babolsar fishing ports during winter 2013. Totally, 330 specimens (272 specimens from Amir Abad port and 58 specimens from Babolsar port) were caught by lift net and 30 absolute morphometric traits, 9 meristic traits, length and gonad, body wei...
The search for renewable energy supplies today’s global demand, particularly ocean wave coastal areas, has become undeniably widespread in the last two decades. Caspian Sea represents an immense opportunity using energy, especially considering its long shoreline. In this study, locations with maximum potential were chosen central, eastern, and western zones of Sea’s southern coasts. Accordingly...
In this study, the growth parameters of Common Kilka (Clupeonella cultriventris) in the Caspian Sea were studied in one season and, three stations of Babolsar, Bandar Amirabad and Bandar Anzali. A total number of samples, 300 fish were randomly caught by conical nets in the study areas and analyzed. Overall, the average total length of the three stations 11.65 ± 1.17 cm and 9.64 ± 2.58 g total ...
Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...
changes in abundance and biomass of cyanobacteria have been studied in the southern part of the caspian sea (the stretch between tonekabon and amirabad) in four seasons (spring, summer, autumn, winter) in which samples were taken from five depths of 5, 10, 20, 50 and 100 meters in the stations of tonekabon, noushahr, babolsar and amirabad. samples were fixed in formalin (2-2.5%) before transfer...
The research study the effect of changing light color on the length and weight composition of common sprat (C. caspia) catch in conical lift net with a mesh size of 8 mm (knot to knot). For this purpose, in January 2018 the sprat fish caught by three fishing vessels during 30 times of fishing operations at 50-40 m depth in Amirabad fishing port. The results showed that from total number of 2874...
