How does the Order of streams in ArcGIS work?
Stream ordering is a method of assigning a numeric order to links in a stream network. This order is a method for identifying and classifying types of streams based on their numbers of tributaries. Some characteristics of streams can be inferred by simply knowing their order.
Which is the correct method for assigning stream order?
The method used for assigning stream order. STRAHLER — The method of stream ordering proposed by Strahler in 1952. Stream order only increases when streams of the same order intersect. Therefore, the intersection of a first-order and second-order link will remain a second-order link, rather than creating a third-order link. This is the default.
When does the Order of a stream increase?
Stream order only increases when streams of the same order intersect. Therefore, the intersection of a first-order and second-order link will remain a second-order link, rather than creating a third-order link. This is the default. SHREVE — The method of stream ordering by magnitude, proposed by Shreve in 1967.
How do I add streamnet layer to ArcMap?

Can you do multiple field frequency calculations in ArcGIS?
However, in ArcGIS 8.3 or when operating under the ArcEditor or ArcView licenses of ArcGIS 9.x, this option does not exist. In these cases, multiple field frequency calculations can be accomplished in the geodatabase by using the underlying database to execute a query that will return this information.

How to assign order to links in stream network?
The Stream Ordertool has two methods of assigning a numeric order to links in a stream network. While the default Strahler method is the most common, the Shreve method offers the benefit of not being as sensitive to the addition and removal of links from further analysis. Stream links
