Getting Started with HRUs

Requirements for Input Layers

All three necessary input layers must be polygon layers and included in the current QGIS project. Additionally a raster DEM layer can be used as input to calculate the slope.

1. Sub-basin layer

   This layer should contain the sub-basins as well as a field for Unique Identifiers and another one for slope.

2. Soil Layer

   This layer should contain all soil types within the study area and can consist of up to 6 soil layers. It must contain at least a field specifying the names of the soil types of one soil layer.

3. Land Use Layer

   This layer should contain all land use areas within the study area, and it must contain a field specifying the names of the land use types.

4. Optional: DEM Layer

   The DEM layer is optional, and if a DEM layer is uploaded, the slope for each HRU will be calculated.
