Rivers and streams from 1st - 11th order, as defined by Stahler (1957), are included. First order streams were delimited with a drainage threshold of ~90 ha. Since this is larger than the basin size of 10 -50 ha normally attributed to 1st order streams in the Central Amazon, stream order may be underestimated by 1.<TABLE><TBODY><TR><TD>Variables</TD><TD>Description</TD></TR><TR><TD>OBJECTID</TD><TD>Object identifier</TD></TR><TR><TD>LENGTHKM</TD><TD>The length (km) of each segment</TD></TR><TR><TD>Shape_Length</TD><TD>Length in degrees - NOT USE</TD></TR><TR><TD>river_order</TD><TD>River order with Strahler (1957) classification system</TD></TR></TBODY></TABLE></DIV></DIV></DIV> Rivers Order Strahler Authors: Eduardo Venticinque1, Bruce Forsberg2, Ronaldo B.
