Origin and composition of sediments in a highly stratified karstic estuary: An example of the Zrmanja River estuary (eastern Adriatic)

A simplified end-member mixing model (EMMA) was proposed to explain possible contributors to the sediment composition in the estuary and their relative mixing proportions. The presented model allows prediction of contribution of different material sources, even at contributions of less than 10%, on the basis of basic and easily measurable parameters (Mz, percentages of sand, silt and clay, and percentages of CaCO3 and TOC).
