Análise da incerteza do mapeamento batimétrico do canal de navegação do porto do Mucuripe (CE) – Brasil

Abstract

The harbor activity represents an important source o f in come generation and foreign exchange is regarded as the key to regional socio-economic development. So, it is necessary the constant monitoring of the navigation channels, since the good state of repair, directly contributes to safety in boat traffic. For this, are usually carried out dredging in arcas adjacent to port facilities, and the bathymetric survey the most appropriate methodology for monitoring the depths after the dredging. However, there is little discussion regarding the analysis o f the accuracy o f the bathymetry maps. In this context, the recent advancement o f computational techniques applied, can facilitate the achievement o f a detailed study to ascertain potential arcas o f uncertainty in a survey previously conducted. Thus, this study sought to contribute to the improvement of bathymetry techniques based on geostatistics from the generation of a map of uncertainty, seeking review of the accuracy of surveys in harbor zones.The results show the feasibility and advisability of implementing techniques o f indicator kriging by a\lowing the analysis of the uncertainties arising from the ordinary interpolation
