watershedBC

Overview

The watershedBC is an [experimental]{.underline} interactive R Shiny app that allows users to explore and summarize watershed attributes in British Columbia. The app utilizes data from the BC Data Catalog to provide valuable on-demand reports about various characteristics of watersheds across the province.

How the app works

Step 1: Watershed Delineation

There are four datasets to chose from to select watersheds, they are:

• Freshwater Atlas Named Watersheds: These watersheds are used directly from the Freshwater Atlas of BC with no additional processing.
• Freshwater Atlas Watersheds by Stream Order: These fundamental watershed units have been 'rolled-up' by stream order such that every stream segment now has a polygon that represents the entire watershed.
• Water Survey of Canada Hydrometric Basins: These are watersheds published by the federal government that represent the watersheds above actual Water Survey of Canada Hydrometric Station locations.
• Custom Watersheds at Point of Interest: This is an unpublished dataset that uses the the BC TRIM DEM and extracts a watershed at every location 1 km along every waterway in the province.

Step 2: Current Modules

There are currently six four datasets to chose from to select watersheds, they are:

1. Streamflow and Freshwater Resources

   • Freshwater Atlas
     Summarize wetlands, lakes and glaciers from the FWA

   • Glacier Change
     Summarize glacier change between 1985 and 2021

   • Discharge Estimate
     Estimate the long term mean daily discharge at for any watershed

2. Forest Disturbance

   • Cutblocks
     Summarize the total area of cutblocks by harvest year

   • Wildfire
     Summarize the total area of wildfires by harvest year

   • Roads
     Summarize the total length of roads by type

   • Simplified ECA
     Provide a Simplified ECA, which is a 40 year recovery period for harvest and wildfire relative to the total basin area. [This is NOT ECA!]{.underline}

3. Stream Profile

   • Stream Profile**
     Plot the stream profile of all of the named streams in your watershed

4. Water Allocations

   • Water Rights
     Total allocated water rights

   • Water Authorizations
     Total allocated water authorizations

5. ClimateBC

   • Mean Annual Precipitation
     Sample points across the watershed from ClimateBC MAP

   • Mean Annual Air Temperature
     Sample points across the watershed from ClimateBC MAT

   • Cumulative Moisture Deficit
     Sample points across the watershed from ClimateBC CMD

6. Satellite Imagery

   • Sentinel - 2023
     Cloud free sentinel-2 mosaic of BC

   • Landsat - 2020
     Cloud free Landsat 8 mosaic of BC

   • Landsat - 1985
     Cloud free Landsat 5 mosaic of BC
