Os perfis longitudinal e transversal apresentam-se como representações, retratando a diferenças do gradiente do canal e fisiologia das vertentes. Desta forma neste artigo objetiva-se apresentar as técnicas de representação geomorfológicas através dos perfis longitudinal e transversais utilizando a bacia hidrográfica do córrego Pinhalzinho II na região Noroeste do Paraná como base. As representações do relevo ajudam na compreensão dos fenômenos meteorológicos e hidrosedimentológicos que afetam os processos erosivos que reformulam novas feições do contexto da evolução da paisagem. As constatações verificadas demonstram que o perfil longitudinal da bacia, aplicando o índice RDE encontra-se parcialmente em equilíbrio, apresentando somente o trecho final de seu perfil em desajuste fluvial. Os perfis transversais possuem vertentes com convexidade e concavidades com segmentos retilíneos, caracterizando um relevo suave com dimensão interflúvial que atenua a forte incisão do vale apresentando baixa dissecação do relevo. Os estudos de representação geomorfológicos contribuem para a identificação de diversas variáveis ambientais, representadas pelos fenômenos tectônicos, sedimentares, e uso do solo de cada região aplicada.

The Use of Profiles Transverse to Longitudinal Studies in the Basin Geomorphological Pinhalzinho II Stream Northwest of Paraná / Brazil
ABSTRACT
The longitudinal and transverse profiles are presented as representations, depicting the differences of the channel gradient and physiological aspects. This article aims to present the techniques of representation through the geomorphological longitudinal and transverse profiles using the watershed stream Pinhalzinho II in the Northwest of Paraná as a basis. The representations of relief aid in the understanding of meteorological phenomena that affect the hydro-sedimentological and erosional processes revising new features of the context of the evolution of the local landscape. The findings show that the observed longitudinal profile of the basin, applying the index RDE is partially balanced, presenting only the final section of your profile misfit river. The transverse profiles are convex and concave slopes with straight segments, featuring a soft dimension with interfluvial that mitigates the strong incision of the valley dissection presenting low relief. Geomorphological studies of representation contribute to the identification of several environmental variables, represented by tectonic phenomena, sedimentary, and land use in each region applied.
Keywords: morphometric analysis, Geoenvironmental Mapping, longitudinal profile, transverse profile, gradient index RDE.
