Fenómenos de Sufosión (piping) en la depresión media del Ebro

Abstract: Piping processes are very common in the middle Ebro basin. This paper describes several local examples of subsurface erosion and so morphological aspects, geomorphic situation and genetic circunstances are analyzed.

“…Geologically, the study site is located in the " Lomas de Las Tapias " formation, which is composed of sandstones, claystones, siltstones, and stratified conglomerates, and the " Torrecitas " formation, composed of tuffs and outcrops of travertine deposits ( Contreras et al 1999 ). Suffossion or piping processes occur in La Laja, i.e., natural holes (pipes) are formed and further developed in the soil or other unconsolidated deposits by eluviation or subsurface differential erosion processes ( Guti é rrez Elorza and Rodriguez Vidal 1984 ), resulting in a release of travertine Brought to you by | Cambridge University Library Authenticated Download Date | 1/2/15 4:51 PM material ( Yacante et al 1997 ) and slabs, carbonate rocks with several plant impressions. These processes occurring in La Laja may be induced by the arid climate, heavy precipitations, and sparse vegetation ( Yacante et al 1997 ).…”

“…Así, la erosión sobre las arcillas ricas en sodio se produce en cualquier tipo de evento lluvioso, mientras que sobre las arcillas con bajo contenido en sodio, tan sólo las lluvias considerables producen sedimentos (BENITO et al, 1991). Además, el alto contenido en sodio provoca importantes fenómenos de erosión subsuperficial o "piping" (GUTIÉRREZ et al, 1988;GUTIÉRREZ et al, 1994). Los "pipes" llegan a colapsarse, formando regueros que ocasionan un aumento de la erosión en las zonas interregueros.…”

“…No es dificil observar en ellos la deposición de tepés, paquetes de matorral o incluso pinos de repoblación, desprendidos por el retroceso de la parte superior del talud. Sobre todo al pie de las vertientes (cauces de tercer orden), los canales presentan fondo plano y paredes muy verticales, resultado de los procesos de piping o sufosión (GUTIÉRREZ-ELORZA y RODRÍGUEZ-VIDAL, 1984).…”
