Formation conditions and morphology of free bends on the North-Eurasian rivers

Abstract

The regularities’ of changes of the free bend morphometric characteristics (parameters) and their connection with river water discharges are under consideration. It is established for medium and large rivers that the coefficient in the regression equation "parameter - mean maximal water discharge" depends on the seasonal runoff irregularities. At the same time the relationship "parameter - mean annual water discharge" is stable for all rivers. For small rivers relationship between parameters and water discharges are exponential, close to quadratic, for medium and large rivers - linear, the value of parameter does not depend on water discharge for largest rivers.
