An R Shiny app for remotely identifying stream Ordinary High Water Marks (OHWM) using publicly available terrain data for small sites.
This R Shiny app can be used to remotely identify stream Ordinary High Water Marks (OHWM) using publicly available terrain data for small sites. It has the following features:
- Identify a project site
- Extract the latest available lidar-derived Digital Elevation Model (DEM)
- Draw stream cross sections
- Tools for choosing a bankfull elevation for ungaged streams
- Calculate stream channel dimensions
Geospatial data scientists maintaining OHWM, Floodplain Connectivity, or Tiered Assessment applications should begin with the customer application maintainer guide. It provides Positron/VS Code-oriented procedures for repository setup, synchronization, verification, deployment promotion, and rollback.
Funding for development and maintenance of FluvialGeomorph has been provided by the following US Army Corps of Engineers (USACE) programs:
