Abstract

Identification of shoreline position and mapping are critical for safe navigation, coastal resource management, coastal environmental protection and sustainable coastal development. Nowadays, application of satellite data is the newest and most economical method for this purpose. In this study, satellite data and object-oriented technique are used to determine position of shoreline and to provide shoreline map. The study area is located at the Bord-khun in the Bushehr province. An image provided by TM sensor of Landsat satellite for the study area in 2012 was used for shoreline mapping in this area. At first, geometric and radiometric corrections were performed on the image. Then the study area was classified by object-oriented method and m

Assessment the effect of ENSO on weather temperature changes using fuzzy analysis (case study: Chabahar)

Maryam Hamedani Azmoodehfar, Seyed Ali Azarmsa
Journal PapersAPCBEE procedia , Volume 5 , 2013 January 1, {Pages 508-513 }

Abstract

The effects of El Nino and La Nina have been considered as the major variables in weather changes in the Middle East. This issue has been shown by regression indexes in a number of papers. The presented study has proven that the El Nino and La Nina should be added to the weather forecast variables because of their major effects. Weather forecasts could be influenced by some variables that have uncertainty, so the deterministic approaches may lead to incorrect predictions. The proposed algorithm can be used when some variables have uncertainty. In this study, a probabilistic approach has been chosen to show the effect of El Nino and La Nina on the monthly maximum temperature. Different ENSO Indices have been proposed for El Nino or La Nina o

Journal PapersJournal of Fluid Mechanics , Volume 724 , 2013 June , {Pages May-35 }

Abstract

A laboratory investigation has been undertaken to quantify water wave attenuation rates as a function of rainfall rate. Vertical artificial rainfall is shown to generate weak near-surface velocity fluctuations that decline systematically away from the free surface and are independent of rainfall rate across the range of rainfall rates investigated (40-[formula omitted, refer to PDF]). In the absence of rain, the observed attenuation of gravity waves is at levels consistent with classical viscous theory, but with a systematic finite-amplitude effect observed above a mean steepness of 0.10. Wave attenuation rates were found to be independent of the mean wave steepness and identical when artificial rainfall rates of 108 and [formula omitted, r

Journal PapersInternational Journal of Maritime Technology , Volume 9 , Issue 17, 2013 October 15, {Pages 77-86 }

Abstract

Comparisons made between the measured data carried out from September to December 2012 using a streamer trap and the results of some semi-empirical formulas including CERC, Walton and Bruno (WB), van der Meer (V), Kamphuis (K), and an Artificial Neural Network (ANN) model. Six dominant variables are considered in the ANN model to estimate long-shore sediment transport rate. Results reveal that among the semi-empirical formulas, Kamphuis formula has provided more reliable results than others and its% 7 errors related to the observed data is partially resulted from the errors in input parameters. In contrast, the ANN model provides more accurate results with% 6 error related to measured data and thus it is recommended to be applied in long-sh

Abstract

Wind is a major factor which induces oceanic currents and many theories including the Ekman theory have considered the wind induces currents. In this paper a numerical process has been used for forecasting of oceanic currents based on this theory. The survey has been done in an artificial five layer oceanic basin with smooth bottom of 120 meters, considering the geographic position of Persian Gulf. Primitive equations were solved on earth’s spherical coordinates system with sigma as vertical coordinate by finite element method. Vertical profile of predicted current vectors showed the complete formation of Ekman Spiral in the basin. This experimental simulation is a new approach for confirmation of Ekman Theory.

Abstract

INTRODUCTION: IT IS WELL ACCEPTED THAT WAVES AT THE SURFACE OF THE DEEP OCEAN CAN BE WELL PREDICTED WITH THIRD-GENERATION WAVE MODELS, BASED ON THE ENERGY OR ACTION BALANCE EQUATION. HOWEVER, THESE KIND OF MODELS CANNOT BE REALISTICALLY APPLIED TO COASTAL REGIONS WITH HORIZONTAL SCALES LESS THAN 20-30 KM AND WATER DEPTH LESS THAN 20-30 M DUE TO THEIR LIMITS RELATED TO BOTH SHALLOW WATER EFFECTS AND NUMERICAL TECHNIQUES. IN FACT, SWAN WAVE MODEL ACCOUNTS FOR REFRACTION, WAVE GENERATION BY WIND, TRIAD WAVE-WAVE INTERACTIONS, DEPTH-INDUCED WAVE BREAKING AND WAVE REFLECTION AGAINST OBSTACLES (SUCH AS COASTLINES OR BREAKWATERS), IN ADDITION TO THE EFFECTS ALREADY INCLUDED IN OTHER MODELS SUCH AS WAM. ALSO, WAVE PROPAGATION IN CARTESIAN SYSTEM IN

Abstract

Sediment transport driven by current, wind and wave plays an important role in influencing the evolution of offshore and onshore bed morphologies by deposition and erosion erosion Subject Category: Natural Processessee more details. Correspondingly, the offshore and onshore industrial devices may be seriously damaged in some extremely cases like typhoons, hurricanes and so on. Therefore, one of the most important issues for coastal engineering is suitable structure layout. Also, the study on sediment transport phenomena under various environmental conditions is an important subject to both coastal engineers and researchers.

Journal PapersAquatic Ecosystem Health & Management , Volume 12 , Issue 4, 2009 November 30, {Pages 358-363 }

Abstract

Coastal managers and ecologists are confronted with tasks to estimate wave heights in the Kiashahr sea area, since hydrodynamic factors can profoundly impact this environment. In this study, wind data and an empirical wind wave predicting model were used to estimate deepwater wave characteristics in the Kiashahr sea area; while a numerical model was used to determine wave characteristics in shallow waters. Wave heights were also determined and compared at different stations before and after construction of 2 jetties at the lagoon mouth to evaluate their efficiency in wave height reduction. Results revealed that wave height is in the range of 0.8 to 1.2 m at Sefid Rud river mouth. Significant wave height reduction in the range of 0.15 to 1.2

Journal Papers , 2008 January , {Pages }

Abstract

Thermal structure was studied in the northern coastal part of the Persian Gulf in Iranian southern province of Bushehr. Temperature measurements revealed that the morning–afternoon temperature variations were in the range of 0.2 – 4?C at deeper layers and 0.2 – 1.7?C near the sea surface. The range of the morning–afternoon temperature variations was also time dependent and reduced from a maximum value of 4?C in August to its minimum value of 0.2?C in November. Monthly average of the seawater temperature decreased about 7.4?C in the temperature decreasing period of August to November; with the maximum thermal gradient of about 3.8?C / month occurred in transition from October to November.

Journal PapersEarth Sciences , Issue 60, 2006 January 1, {Pages 25-32 }

Abstract

Managing coastal zones needs accurate and updated information about coastline position. Coastlines continuously change due to wave, tide, and etc. actions. Therefore, it is necessary to have enough information on coastline position not only in the present time, but also in the past and future in order to organize scientific and engineering activities in a coastal zone. Satellite data are the best and most economic method for collecting such data. In this paper, three images provided by TM sensor of Landsat satellite were used for extracting coastline positions and investigating their changes in a period of 13 years. The images were prepared for further processing like radiometric corrections and geocoding. Then shoreline position correspond

Journal Papers , Volume 31 , Issue 1, 2005 January 1, {Pages 167-180 }

Abstract

Study of tide is one of the most important needs for scientists, engineers, port managers etc. Persian Gulf is one of the most important regions for transporting oil in the entire world. Harmonic analyses is one of the best methods used for analyzing of tide and the least square method is the best one for it. IOS is a tidal package that uses least square method. In this paper, we investigate the accuracy of IOS tidal package. For this reason, we perform numerical experiments with different lengths of records to determine sensitivity of tidal prediction results to these lengths. We also perform numerical examinations with gaps in data. Results of 25 tests performed in this regard show that if data recording is performed under the calm wave c

Abstract

Wind data recorded every 3 hours at Babolsar synoptic station in southern part of the Caspian Sea and also wave information measured by Neka buoy was used to investigate the wave climate in this region. For this purpose, monthly and seasonally wind roses of the region were drawn. The results reveal that most of the time the weather is calm. Besides, the dominant direction of the wind is northerly. Further, with the help of software provided in visual basic environment, the wind duration in different conditions was calculated. The results confirm that duration of winds of higher intensity is shorter.

Journal Papers , Volume 1 , Issue 1, 2004 January 1, {Pages 77-85 }

Abstract

Nowadays, for managing coastal zones and littoral lands, we need accurate and updated information on hydrography of coastal areas. These data can be obtained by local measurements, airborne imagery and satellite data. Using satellite data is not time consuming and expensive like than other methods, thus it is most economical method in the world. Unfortunately, this method is not developed in Iran, although it has many advantages. In this paper, the advantages of Landsat data have been taken to provide hydrographical maps after applying some specific image processing techniques. Landsat TM images were used.

Journal Papers , Volume 1 , Issue 4, 2002 January 1, {Pages 10-Jan }

Abstract

One of the facing problems in Urumia Lake is the construction of a connecting way on it. Because of the importance of the problem, different activities have been performed in this relation. However, due to specific conditions of the lake, proposed or applied solutions were less successful. Construction of a concrete floating bridge as a new alternative for connecting two sides of the lake may be a good solution. Thus, it is very important to review and assess the specifications and characteristics of this special type of bridge as well as to perform a feasibility study about the possibility of using such a bridge as an important high traffic connecting way.

Cause and characteristics of impact pressure exerted by spilling and plunging breakers on a vertical wall

Seyed Ali Azarmsa, Takashi Yasuda, Hidemi Mutsuda
Journal Papers , 1997 January , {Pages 2442-2455 }

Abstract

Detailed measurements of spilling and plunging wave pressures on a vertical wall are carried out to identify and compare their characteristics. Kinematical differences between the spilling and plunging breakers enable us to investigate better the generation mechanism and characteristics of the impact pressure. Further, the reliability of numerically computed breaking wave pressure is investigated through the comparisons with the experimental results. It is made clear that the impact pressure can be well expressed in terms of internal kinematics of breaking waves.
