🔎 Preliminary watershed delineation for the Inhulets River study

One of the early intermediate products from my broader research on the anthropogenic impacts on the #InhuletsRiver.
This map shows a preliminary delineation of local drainage basins across the study area, derived from high-resolution DEM processing and hydrological modelling.

The goal of this stage is to establish a consistent spatial framework for later analyses — including flow pathways, contaminant transport patterns, and the interaction between surface and groundwater systems.

This is how the effective catchment area of the Inhulets River looks within the study region.

The upstream part — above the Karachunivske Reservoir's dam, the outlet of the Saksahan derivative tunnel, and the confluence of the Stara Saksahan River — was excluded from the calculation.

Within the analyzed area, surface runoff is possible only from the highlighted zone.
The rest of the “catchment basin” is hydrologically inactive: runoff is intercepted by ponds, settling tanks, and other anthropogenic landforms.

🌍 The analysis was based on the Copernicus GLO-30 DEM, integrated with hydrological modeling and terrain processing in open-source GIS.
