Una revisión de los procesos de sufosión o piping en España

Authors: J. M. García-Ruiz;

Una revisión de los procesos de sufosión o piping en España

Abstract

Se revisan los estudios que hacen referencia al desarrollo de procesos de sufosión o piping en España. La mayor parte de los trabajos se centran en ambientes semiáridos de la Depresión del Ebro y del Sureste de España, donde llegan a formarse redes subsuperficiales de drenaje muy complejas, dando lugar ocasionalmente a grandes colapsos que a su vez favorecen la evolución de cárcavas. En muchos casos el piping se asocia a la presencia de badlands. La sufosión tiene especial relevancia en suelos y materiales poco consolidados sobre afloramientos de rocas blandas (margas y lutitas), con abundantes arcillas expansivas y sodio, lo que reduce la coherencia de los materiales. La existencia de fuertes gradientes hidráulicos (asociados al aterrazamiento de campos de cultivo o a la incisión por parte de cárcavas) es un factor imprescindible. Muchos de los problemas relacionados con la sufosión se originan en antiguos campos de cultivo y, a veces, en campos regados. En áreas de montaña se ha citado la presencia de redes de drenaje subsuperficiales relacionadas con madrigueras y raíces muertas, aunque no conducen al desarrollo de cárcavas.
