Aprovechamiento educativo y turístico de formas erosivas tipo pilares de tierra (earth pillars, hoodoos) : ejemplos de la riera de Gaià (Vallès occidental, Barcelona) y del Bernal de Yátor (la Alpujarra, Granada)

Se describen los principales rasgos geomorfológicos de las formas erosivas de tipo pilares de tierra que se desarrollan en la Riera de Gaià (Barcelona) y en el Bernal de Yátor (Granada) Se trata de formas dinámicas, propias de zonas sometidas a una fuerte erosión hídrica, con un elevado interés científico, estético y didáctico

Susceptibilidade erosiva do baixo curso do rio Acaraú-CE

The inadequate land use in the low course of the river Acaraú is speeding up processes of erosion in some degrees. This process is accented in the areas where caatinga was removed for implantation of pastures and agriculture. Concomitantly, the plain of flooding of the river Acaraú an accumulation of sand with the carry of these sediments, resulting in the widening of the fluvial plain and reduction of the shape water, with increase of the evapotranspiration and consequence salinization, proceeding from the local substratum. This paper aimed at the crossing of diverse space information (geomorfology, soil, declivity, geology and land use) in environment SIG, for determination of the susceptible areas to the erosion and an accumulation of sand in the low course of the Acaraú river, north of the State of the Ceará, Brazil. The results allow to evaluate the application of this tool in the planning and management of the environment, from the crossing of the type of use with the used environment and the consequent impact to the ecosystem.
