Accurate predictive modelling requires rigorous preparation and harmonisation of spatial and non-spatial input data.
The preparation workflow includes:
1. Spatial Delineation and Hydrological Structuring
-
Catchment and sub-basin delineation
-
River network extraction
-
Identification of hydrological response units
2. Land Use and Soil Parameterisation
-
Harmonisation of land-use classifications
-
Soil property mapping
-
Assignment of crop management parameters
3. NSWRM Parameterisation
-
Translation of structural and management measures into model parameters
-
Definition of infiltration rates, retention capacities, drainage coefficients
-
Representation of conservation tillage, cover crops and vegetative measures
4. Climate Data Integration
-
Historical climate datasets
-
Bias-corrected climate projections
-
Integration into modelling workflows
Additional methodological developments addressed data scarcity challenges, including preprocessing tools and standardised parameterisation guidelines to ensure cross-regional comparability.
Through this structured preparation phase, OPTAIN ensures that optimisation results are derived from calibrated, harmonised and context-specific modelling environments, enabling meaningful comparison across case studies.
