The declining but non-rejuvenating base level. The Lisan Lake, the Dead Sea area, Israel

Auteur :
BOWMAN, D.

Description :
The study area is an entrenched fan delta with a sequence of 14 unpaired fan terraces which die out at intersection points within an alluvial fan system. The results suggest that the intersection points did not function as base levels. The receding base level played only a passive role, allowing entrenchment without transmitting a head-cutting feedback basinwards. The arid environment caused a delay in transmission of information through the system. It is suggested that base level effects in temperate and humid regions are not transferrable to arid zones.
