Code Descriptions:
Flow_wave_finder.R: Finding flow waves from Surface Water and Ocean Topography (SWOT) water surface elevation measurements by analyzing US Geological Survey gauge height variations.
Flow_wave_length.R: Estimating the spatial length of flow waves from SWOT data.
Spatial_hydrograph_separation.R: Applying a single-parameter digital filter from Chapman and Maxwell (1996) to separate baseflow from total flow for both SWOT and gauge data.
