hydrofab: Fabricating Hydrofabrics

R CMD Check Dependencies License: Apache License (>= 2)

The goal of hydrofab is to provide consistent hydrologic and hydraulic network manipulation tool chains to achieve model application ready datasets.

Installation

You can install the development version of hydrofab like so:

install.packages("remotes")
remotes::install_github("NOAA-OWP/hydrofab")

Refactoring and Aggregating

The concept of refactoring as intended here includes:

  1. Splitting large or long catchments to create a more uniform catchment size distribution,
  2. collapsing catchment topology to eliminate small catchments

The concept of aggregating as intended here includes aggregating catchments into groups based on existing network topology and defined criteria. Two primary use cases are offered:

  1. Aggregating to a set of defined outlet locations
  2. Merging catchments to a uniform size with enforced minimum areas and lengths.

This type of functionality is especially relevant to modeling applications that need specific modeling unit characteristics but wish to preserve the network as much as possible for interoperability with other applications
