STUDY ON THE QUANTITATIVE MODEL FOR POINT BAR OF MODERN MEANDERING RIVER

By measuring the geometric parameters of 27 typical point bars of modern meandering river from satellite photographs, the sedimentary characteristics of point bar are studied from quantitatively or semi-quantitatively. The quantitative relation between the length, width of point bar and bankfull width of river is established. This result can be applied in the research for oil reservoir of meandering facies.
