Monitoring the dynamic behavior of shorelines is an essential factor for integrated coastal management (ICM). In this study, satellite-derived shorelines and corresponding eroded and accreted areas of coastal zones have been calculated and assessed for 15 km along the coasts of Ezbet Elborg, Nile Delta, Egypt. A developed approach is designed based on Landsat satellite images combined with GIS to estimate an accurate shoreline changes and study the effect of seawalls on it. Landsat images for the period from 1985 to 2018 are rectified and classified using Supported Vector Machines (SVMs) and then processed using ArcGIS to estimate the effectiveness of the seawall that was constructed in year 2000. Accuracy assessment results show that the SVMs improve images accuracy up to 92.62% and the detected shoreline by the proposed method is highly correlated (0.87) with RTK-GPS measurements. In addition, the shoreline change analysis presents that a dramatic erosion of 2.1 km2 east of Ezbet Elborg seawall has occurred. Also, the total accretion areas are equal to 4.40 km2 and 10.50 km2 in between 1985-and-2000 and 2000-and-2018, respectively, along the southeast side of the study area.

This paper attempts to contribute towards investigating the existing literature base of stakeholder management (SM), provide a compilation, and define any gaps in this area. Besides, explore different groups of critical success factors (CSFs) and grouping these actors. This study is based on reviewing the literature. Therefore, more than a hundred research papers were searched by the key terms specified in a preceding literature review. Succeeding tours of abstract research surveys resulted in forty-two research papers being picked for the compilation. SM constructs were identified, and the following crucial analysis defined the literature base gaps. The most notable outcomes are the absence of research that has studied BIM-based stakeholder management, especially in mega projects. Additionally, further investigations are still required to study the SM influence throughout the different stages of the project life cycle and study the impact of project type and contract type in SM. However, there is still considerable debate about the SM nature and merits approach. This study presents a comprehensive gathering of all earlier identified SM processes through a structured approach. Additionally, a more realistic and practical methodology for the development and implementation of SM will emerge, and twenty-seven CSFs associated with SM in construction projects are identified. The study is expected to have a theoretical contribution to this subject, especially in the context of the Qatari construction industry.

Purpose The construction industry is facing massive challenges due to the huge construction development, and stakeholder management (SM) practices, especially on megaprojects. The purpose of this paper is to investigate critical success factors (CSFs) encountered by key construction stakeholders to enhance SM practices on mega construction projects (MCPs). Design/methodology/approach A questionnaire survey is carried out among the most important construction companies in Qatar. Three steps are used to finalize and evaluate the questionnaire before proceeding with the full survey, validity, pretesting and pilot study. Quantitative data analysis was conducted using the Statistical Package for Social Science software. Findings This paper identifies the key factors contributing to improving SM performance in MCPs; none of these is uncommon, but here they come together in a more integrative way. Research limitations/implications The limitations related to this research are briefly outlined as follows: the research was carried out in the State of Qatar. So, the findings are limited to the Qatari construction industry. The construction industry in Qatar is different from other countries where public projects have the priority to develop the infrastructure of the country prior to the world cup competition. The scope of this research is limited to MCPs. The impact of low awareness and knowledge of SM is not considered. However, the study is still reasonable and fortunately suitable to evaluate SM in MCPs. Practical implications Identifying these factors is expected to assist project participants in MCPs in improving projects’ performance and completing construction within the predefined time and cost. Originality/value This study makes a significant contribution through identifying the CSFs that lead to develop efficient SM in MCPs. Moreover, the research findings are important for project stakeholders, organizations, contractors, engineers and local authorities who implement SM in MCPs. Moreover, it will enhance the application of SM practices in construction megaprojects and allow project key stakeholders to place emphasis on tackling the crucial challenges identified in this research.
