River Slope Analysis Using SWOT Node Data

This dataset supports Table 1 of the associated publication and provides slope statistics derived from SWOT node-based water surface elevation (WSE) profiles. The analysis focuses on slope changes across the Chilcotin river between July and September 2024.

Data Contents

Excel (.xlsx) files
SWOT node data used to compute river slope profiles upstream and downstream of the landslide site for three observation dates:

• WSE_nodes_2024-07-12.xlsx

• WSE_nodes_2024-08-13.xlsx

• WSE_nodes_2024-09-08.xlsx

Data sources and products

• SWOT WSE Node Data – Product: SWOT L2_HR_RiverSP_Node, accessed via NASA Earthdata Search

Variables

Each file includes the following columns:

• WSE (Water Surface Elevation) [m]
• ‘p_dist_out’ (distance to outlet) [m]
• Water surface elevation uncertainty (‘wse_u’) provided in the node product [m]
