Processos erosivos têm se mostrado ao longo do tempo como eficazes modificadores da 'paisagem. No entanto, o pouco conhecimento de suas causas tem dificultado bastante o melhor entendimento das intensidades e periodicidade de suas atuações, bem como de seus danos. A meta principal desta abordagem é o reconhecimento e entendimento dos agentes erosivos atuantes no caso, buscando discutir e sugerir formas que permitam uma melhor coexistência do homem com esses inevitáveis processos da natureza. Assim, o trabalho apresenta primeiramente uma análise sobre os vários aspectos que compõem a fisiografia marajoara, incluindo observações de campo e de registros históricos, os quais auxiliaram na identificação dos principais fatores atuantes no processo erosivo e na quantificação da evolução temporal do processo. Palavras-chave: erosão, mudança de paisagem, Marajó.

Conjugated action of erosive agents accelerates changes in the landscape of the city of Chaves, north coast of the Marajó Island. Erosive processes are known as effective modifiers of the landscape along the time. However, the poor knowledge of their causes difficulties the adequate understanding of the intensities and periodicity of their performances, as well as of the resultant damages. The main goal here is to recognize and understand the erosive agents, aiming to discuss and suggest forms to improve better coexistence of human being with those inevitable nature processes. Thus, this paper presents an analysis on the several aspects that compose the Marajo Island physiography, with support of field observations and historical registrations, which aided in the identification of the main factors causing erosive process and in the quantification of its temporary evolution.
Keywords: erosive process, landform changes, Marajó.
