The Impact

 O Geossistema, como método de análise integrado dos sistemas ambientais, surgiu como ferramenta capaz de suprir, em parte, a necessidade humana de compreender e descrever os processos naturais responsáveis pela organização elementar existente em cada paisagem. O estudo em Geossistema, aplicado ao ambiente litorâneo, pode apresentar um nível de análise de maior complexidade, se comparado ao continente, em função da origem dos elementos e processos dinâmicos existentes em suas paisagens peculiares. Este nível de complexidade é percebido ao longo da Planície Costeira do Amapá (PCA), onde a fisiologia da paisagem deriva principalmente de uma dinâmica geológica, geomorfológica e climática de longo e curto período. O presente trabalho teve como objetivo principal a compartimentação da Região Natural do Cabo Norte, em paisagens síntese, através do método geossistêmico proposto por Bertrand (1968). Os resultados alcançados identificaram três Geossistemas (Ambiente de Sedimentação Paleofluvial e Lacustre, Ambiente de Sedimentação Estuarina, Ambiente de Sedimentação Costeiro e Marinho) que posteriormente foram submetidos ao Índice Qualitativo de Sensibilidade Ambiental adaptado de BRASIL (2004). Como produto foram gerados os mapas de compartimentação da paisagem (Geossistemas) e sensibilidade ao impacto de derramamento de óleo na Região Natural do Cabo Norte. Palavras-chave: Geossistema, paisagem, planície, sensibilidade, Cabo Norte. Abstract The geosystem, as a method of integrated environmental systems analysis, emerged as a tool capable of supplying, in part, the human need to understand and describe natural processes responsible for the elementary organisation exists in each landscape. The study on geosystem, applied to the coastal environment, can present a more sophisticated analysis level, compared to the mainland, according to the origin of the elements and dynamic processes in their peculiar landscapes. This level of complexity is realised along the coastal plain of Amapá (PCA), where the landscape mainly derived from the physiology of a geological, geomorphological and climatic dynamics of long and short period. The present work had as main objective the compartmentalisation of the natural region of the North Cape, in landscapes synthesis, through the geosistemic method proposed by Bertrand (1968). The results identified three geosystems (Paleofluvial and Lacustrine Sedimentation environment, Estuarine Sedimentation environment, Coastal Sedimentation and marine environment) which subsequently underwent a qualitative Index of Environmental sensitivity adapted from BRASIL (2004). As product subdivision maps were generated from the landscape (geosystem) and sensitivity to the impact of the oil spill in the region of North Cape. Keywords: geosystem, landscape, plains, sensitivity, North Cape.

Research on marine dynamics, including coastal wave motions, is a concern of countries in the world in general and Vietnam in particular. Coastal wave dynamics has a direct impact on human activities including coastal construction, shipping, irrigation, aquatic resources exploitation, etc. The coastal area of Nhat Le, Quang Binh is one of the areas strongly influenced by the coastal wave regime which increases the risk of coastal erosion, estuarine sedimentation, destroys the economic life, affects marine fishing and directly affects the tourist beach area. This article aims to introduce some research results based on the application of MIKE21-SW model of the Danish Hydraulic Institute (DHI) to simulate coastal wave regime in Nhat Le coastal zone, Quang Binh province. The model results are verified by real-time wave data in long-term from the WaMoS® II Radar System at Quang Binh station. The results show that there are many similarities in wave height and direction between the computational model and the actual observation data from the radar system. This result will be an important basis for research and application for coastal protection, reduction in river mouth sedimentation, clearing and flood drainage in the study area.
