Abstract:

A programmable calculator (20) is connected to a pumping sampler (12) by an interface circuit board (22). The calculator has a sediment sampling program stored therein and includes a timer (60) to periodically wake up the calculator. Sediment collection is controlled by a Selection At List Time (SALT) scheme in which the probability of taking a sample is proportional to its estimated contribution to total sediment discharge, or according to accumulated predicted sediment weight. Stage height is also measured and is recorded according to a set scheme.
