### Strahler number

The Strahler number `strahler_n` is a measure of branching complexity defined by {cite:p}`Strahler1952` commonly used in hydrological applications. A Strahler number of 0 indicates a centerline without any tributaries. A Strahler number of 1 indicates a centerline with one or more upstream tributaries of the same order, i.e. each of them having a Strahler number of 0. If a centerline with a Strahler number of 1 meets a downglacier centerline, the latter is assigned a Strahler number of 2. This ordering is important for mass flow routing. Each centerline contains a reference to its descendant, and this reference might be used by models to transfer mass from the tributaries towards the main centerline. Note that in the original concept Strahler numbers start with 1 instead of 0.

Neither the original algorithm nor its implementation in OGGM are perfect, and it is likely that centerlines on individual glaciers would be drawn differently by a human or other algorithms. We note that we do not use any velocity product but rely purely on geometric and topographic considerations.</p>
