Estudo da distribuição dos sedimentos da zona perigosa até zona segura da praia de Xai-Xai, Província de Gaza

Abstract

The granulometry is the basis for accurate description of sediments and their distribution, can be characteristic of sediments deposited in certain environments. Therefore, the present study aimed to study the distribution of sediments from the safe and dangerous zone of Xai-Xai beach in the province of Gaza. A field trip was carried out in which 12 samples were collected in the cross-sectional and longitudinal profile of the study area, which were treated in the soil laboratory of the ESCMC-UEM which consisted of removal of carbonates in a solution of HCl-30% and then the granulometric analysis was carried out in the laboratory of the ISHCT-UP Engineering, in which the appropriate sieves were selected, using the sieving technique. The weights held in each sieve were used to construct charts using Microsoft Office Excel. The results showed that from the dangerous zone the sediments tended to diminish their size, and on average the sediments that characterize the beach are medium sands. Such distribution is influenced by hydrodynamic processes that occur at the place of study, such as: strong wave energy, coastal drift currents as well as beach slope.
