hydrofab: Fabricating Hydrofabrics

The goal of hydrofab is to provide consistent hydrologic and hydraulic network manipulation tool chains to achieve model application ready datasets from a consistent reference fabric. Some of these are being built at ngen.hydrofab and gfv2.0

Installation

You can install the development version of hydrofab like so:

install.packages("remotes")
remotes::install_github("mikejohnson51/hydrofab")

Soon to be …

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

Introduction

This package is based around the same concepts as nhdplusTools and uses its utilities extensively. It is the creation of merging the previous hyRefactor and hyAggregate packages in an attempt to provide a common software stack of fabricating hydrofabrics.

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. Aggregating to a uniform catchment 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

Check notes:

In addition to typical R package, a Dockerfile is included in this repository. Once built, it can be run with the following command.

docker build -t hydrofab_test .

# Linux/Mac

docker run --rm -it -v $PWD:/src hydrofab_test /bin/bash -c "cp -r /src/* /check/ && cp /src/.Rbuildignore /check/ && cd /check && Rscript -e 'devtools::build(vignettes = FALSE)' && R CMD check --as-cran ../hydrofab_*"

# Windows
docker run --rm -it -v %cd%:/src hydrofab_test /bin/bash -c "cp -r /src/* /check/ && cp /src/.Rbuildignore /check/ && cd /check && Rscript -e 'devtools::build(vignettes = FALSE)' && R CMD check --as-cran ../hydrofab_"
