bathtub is an R package that estimates the impacts of downstream flooding on stormwater networks using a simple bathtub model, a 1-dimensional infrastructure network, and a minimal amount of data.
The package bathtub:
- Models impacts using a range of water levels
- Models impacts using GIS data representing flooding extents
- Estimates various metrics of impact from high water levels on pipes and structures
- Provides multiple visualization functions ranging from plots to interactive maps
bathtub was designed to be practical and can:
- Download and process elevation data from NOAA and USGS within R (DEMs & lidar)
- Interpolate missing invert elevations within the stormwater network
- Automatically take care of unit conversions and spatial data projections
- Easily visualize, save, & share results
Install
Install bathtub from GitHub using devtools:
library(devtools) install_github("acgold/bathtub")
How it works
bathtub combines spatial representations of the stormwater network and landscape with a 1-dimensional model of the stormwater network. bathtub uses the sf, stars, and raster packages to provide quick and tidy results.
The model works by:
- Estimating overland flooding extents using a simple bathtub model and digital elevation models (DEMs)
- Using the overland flooding extent as a starting point for a 1-D model of stormwater infrastructure
- Propogating flooding through the stormwater network based on invert elevations
