>> I am not familiar with much of any river sedimentation-rate studies. Why do you call them "weir[d] studies"? << They are studies using weirs (troughs to divert water) for measurements of flow and sediment content. they found only a few thousands of years of deposits at the current rates, which due to Man trashing the environment have probably greater sedimentation rates than the past except of course the Great Catastrophe.<g> Kamron
