Part of the water that infiltrates from the surface reaches a zone of saturation whence it percolates toward the outlet and thereby is delayed in its course to the sea. This ground water is one form of natural storage which has different degrees of effect on stream flow in different...
An automatic suspended-sediment sampler
James C. Mundorff
1957, Open-File Report 57-80
The automatic suspended-sediment sampler was originally designed to obtain a suspended-sediment sample from a single point in a stream or reservoir during a rise in stage. The sampler was intended to be used during periods when manually-operated standard samplers could not be used. If the sampling site is remote from the field office...

Generally the procedures described involved measurement of Sr emission at either 460.7...
