Indices for assessing riverscape fragmentation, including the Dendritic Connectivity Index, the Population Connectivity Index, the River Fragmentation Index, the Probability of Connectivity, and the Integral Index of connectivity. For a review, see Jumani et al. (2020) <doi:10.1088/1748-9326/abcb37> and Baldan et al. (2022) <doi:10.1016/j.envsoft.2022.105470> Functions to calculate temporal indices improvement when fragmentation due to barriers is reduced are also included.

Reads river network shape files and computes network distances.
Also included are a variety of tools designed for fisheries research.

Reads river network shape files and computes network distances.
Also included are a variety of computation and graphical tools designed
for fisheries telemetry research, such as minimum home range, kernel density
estimation, and clustering analysis using empirical k-functions with
a bootstrap envelope.  Tools are also provided for editing the river
networks, meaning there is no reliance on external software.

River Network Distance Computation and Applications

Functions for reading, analysing and plotting river networks.
For this package, river networks consist of sections and nodes with associated attributes,
e.g. to characterise their morphological, chemical and biological state.
The package provides functions to read this data from text files, to analyse the network
structure and network paths and regions consisting of sections and nodes that fulfill
prescribed criteria, and to plot the river network and associated properties.

Sankey plots are a type of diagram that is convenient to
illustrate how flow of information, resources etc. separates and joins,
much like observing how rivers split and merge. For example, they can be
used to compare different clusterings.
