Testing A Combination Of Hard And Soft Measures To Enhance The Stability Of Rosetta Outlet

“…Different scenarios, including beach nourishment and hard structures have been tested using CMS. After that, a comparison was implemented between the previous results published by [9] and the recent scenarios in this paper to obtain the optimal scenario capable of restoring the stability of Rosetta promontory taking into consideration the construction cost and the environmental effect. To compare between different scenarios, the hot spot area was divided into three subareas; the eastern, middle and western as shown in Figure 7.…”

Testing A Combination Of Hard And Soft Measures To Enhance The Stability Of Rosetta Outlet

“…On the other hand, the hard structures alternatives were selected in the positions at the boundary of the inlet to ensure trapping longshore sediments, and restoring the beach in the study area. These scenarios are considered an extension to the work published by [9].…”

“…This can be implemented through a testing combination of soft measure (sand nourishment), and hard measures (jetties and groins). This paper is considered an extension to the previous work implemented by [7][8][9].…”

Environmentally- Friendly Proposals for Coastal Stability at Rosetta Promontory, Nile Delta

“…Hence, a variable sized rectangular-cell grid system, with a spatial resolution ranging from 20*20 m around the inlet to 70*120 m near the sea boundary was created. Each CMS grid was forced along the front of seawalls, different alternatives of soft and hard measures were investigated by [15][16][17].…”
