Avaliação das condições hidrológicas de maré para a restauração do mangal - caso do campo de restauro de mangal C do bairro de Icidua, cidade de Quelimane

Abstract

Successful restoration activities in various regions involve several evaluation strands, these being their hydrological conditions. In the neighborhood of Ícidua there is a management restoration activity under the Coastal Cities Adaptation Project (CCAP). The first restored region was unsuccessful, coupled with failure to successfully study conditions for restoration (hydrology, soil quality). It is not making the same mistake in the field of restoration. For the study, the flood time in the region was monitored during 7 consecutive days, to follow the data obtained in the one year period. From the flood time recording data it was possible to calculate the flood time per day and during the month and compared with a Watson (1928) classification. Results of the survey during the month were flooded 13 times, with floods that last in average 152.1 minutes, a total of 304.2 min / day. According to the classification of Waston this region is of class 4 and it is recommended for the restoration of species like Rhizophoras spp, Brugueira spp, Xylocarpus granatum and Lumnitzera racemosa and, according to the classification of Loon et al, (2016) this region It is of class 2 and 3 and it is recommended for the restoration of species such as Avicennia spp., Rhizophora spp., Brugueira spp, Ceriops spp., Brugueira spp.
