The Proper Choice of Coastal Structure for Defense Against the Hydrodynamic Effect of Sea Waves on The Northern Coast of The Nile Delta
Authors
Abstract
Coastal zones worldwide face various challenges because of the hydrodynamic impacts of sea waves, particularly those along vulnerable coastlines like the northern Nile Delta. The research aim is to represent a proper hydrodynamic study for choosing the most suitable protection structure against sea wave action in the surf zone of the Nile Delta. First, it is needed to define the aim of the protection according to the use of the coast. For the cities, it is recommended to use sea walls, while for the tourist sites nourishment is used. The breakwater and groins are to be used for the rest of the coast. In addition, structural resilience and ecological benefits must be balanced. So, the sustainable and resilient coastal defense strategy depends on the cooperation of ecologists, engineers, and policymakers, with potential repercussions for other vulnerable places across the world. This study combines adaptation strategies for dealing with intense climate and sea level rise. In addition, the hydrodynamic study includes different factors like run-up, rip currents, gap between structures, distance from shore, etc. The obtained results and recommendations are presented in the paper.
