Opening the drainage of an endorheic lacustrine basin by fluvial erosion generally implies a lake capture.
Lake captures are therefore very sensitive to the preexisting topography as well as to climatic and lithological factors.
A climatic change towards more humid conditions can result in a higher water level in the internally drained basin, eventually causing overflow, this .
In a longer time-scale, sediment colmatation of the lacustrine basin can also lead to overflow.
Both can hinder the relative importance of the capture process carried out by erosion.
