Description :
The benefits of 3 simple modifications to the design of a Birkbeck bedload slot-sampling system that has been continuously operating in Nabal Eshtemoa, Israel, since the early 1990s are demonstrated : the deployment of a removable slot cover whivh delays the accumulation of sediment; inclusion of a slot the size of which is adjustable; and a sampler side-wall door that allows stratification and textural changes within the accumulated bedload to be identified.
