МОРФОЛОГИЧЕСКОЕ СТРОЕНИЕ РУСЕЛ И ПОЙМ И ИХ ВЛИЯНИЕ НА РУСЛОПОЙМЕННЫЕ ПОТОКИ

The morphology of channel and flood-plain has the large influence on the dynamic of their streams. We brought in a new integral morphometric characteristic - the angle a between geometric axes of flood-plain and channel. We suggested a new method of channel stream average velocity calculation for different relative depths of the channel, based on the empirical graphical dependences and the use of this characteristic. The flood-plain constituent of the stream may also be evaluated by empirical graphical dependences and by the data of relative flood-plain areas and their coefficient of roughness.
