Question

Draw neatly a stream channel ordering in a fourth order strem

Answer 1

Answer:

The Shreve system also gives the outermost tributaries the number "1". Unlike the Strahler method, at a confluence the two numbers are added together.[7]

Shreve stream order is preferred in hydrodynamics: it sums the number of sources in each catchment above a stream gauge or outflow, and correlates roughly to the discharge volumes and pollution levels. Like the Strahler method, it is dependent on the precision of the sources included, but less dependent on map scale. It can be made relatively scale-independent by using suitable normalization and is then largely independent of an exact knowledge of the upper and lower courses of an area.
