Object of class "rivernet" e.g. read by the function |
crit.reach |
Logical vector of the same length as the number of reaches. Indicating whether the criterion for reaches is fulfilled. A single value of |
crit.node |
Logical vector of the same length as the number of nodes. Indicating whether the criterion for nodes is fulfilled. A single value of |
thresh.length |
Threshold length above which not fulfillment of the criterion separates reaches as not being adjacent. |

Numerical vector of the same length as the number of reaches in the river network with unique numbering corresponding to regions of adjacent reaches (under the conditions specified by crit.reach
, crit.node
and thresh.length
). The segment labelled 0 corresponds to reaches which do not fulfill the criteria and are further away than thresh.length
from reaches that fulfill the criteria or which are longer than thresh.length
. The other regions are labelled with 1, 2, 3, ...
