Abstract

The article presents the use of granulometric analysis for the reconstruction of the morphodynamics of an ephemeral stream channel in an arid climatic area. Five deposit facies were identified: bed load, chute, channel bar, natural levee and channel-fill deposits. The first two types were attributed to the morphodynamic erosion zone, while the other three, to the accumulation zone. The course of morphogenetic events in the phase of the disappearance of the flood wave during the last water flow in the studied creek is presented, describing the character of the transport and deposition of alluvia. The fundamental role of the morphodynamics channel zone of accumulation is stressed in the functioning of ephemeral streams during the retreat and disappearance of water. (D'après l'A.).
