Abstract

The repository provides Erosion and Sediment Supply Potential (ESSP) profiles for 111 urban watersheds across the United States, along with R code. The ESSP framework integrates soil texture, impervious surface cover, and geomorphons derived from digital elevation models (DEMs) to estimate spatial variability in sediment supply potential along urban stream corridors.

The methodology is described in the manuscript 'Suspended sediment supply and transport regimes in urban watersheds across the United States.

ESSP_Code.R

ESSP_Code.R is an R script developed to estimate erosion and sediment supply potential along urban stream corridors. The ESSP integrates geomorphons, impervious cover, and soil texture.

Required Data

The script requires spatial datasets representing:

  • Geomorphons
  • Impervious surface cover
  • Soil texture
  • Watershed boundary
  • Stream channel

A sample dataset is included in the SourceData folder to demonstrate the required data structure and format needed to run the script successfully.
