Quantitative approach to sediment source identification by using magnetic diagnosis model

A sequential quantitative approach to sediment source ascription is present ed based on mineral magnetic measurements. Rhode River catchment (USA) and Isabel II reservoir catchment (Spain) were taken as the examples for develo ping the magnetic diagnosis model. The multi-parameter cluster analysis was used to classify the sediment source with respect to their magnetic proper ties, multi-variable mixing model to link magnetic measurement of mixtures with their source component proportions, and linear programming to determin e the sediment source components. It has been shown by these two experiment s that the magnetic diagnosis model is successful for the quantitative sedi ment source ascription. The results correspond well with the relative envir onmental change proxy.
