adjacentreaches.rivernet {rivernet}

Finds Regions of Adjacent Reaches

Description

Finds regions of adjacent reaches that fulfill given criteria.

Usage

## S3 method for class 'rivernet'
adjacentreaches(x,crit.reach,crit.node=TRUE,thresh.length=0,...)

Arguments

x

Object of class "rivernet" e.g. read by the function rivernet.read.

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 TRUE indicates the criterion is fulfilled for all reaches.

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 TRUE indicates the criterion is fulfilled for all nodes.

thresh.length

Threshold length above which not fulfillment of the criterion separates reaches as not being adjacent.

...

.

Value

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, ...
