Description: This dataset contains outputs generated using SD-TOPMODEL for all stages of the process of modelling catchment hydrological responses to a range of real and hypothetical agroforestry planting scenarios at Kiddal Quarry Farm, Yorkshire, between July 2024 and July 2025. The dataset includes modelled responses to both synthetic rainfall events at calibration and testing stages and catchment rainfall event data recorded between July - December 2024 at the validation stage.

* Unless otherwise stated, all included files are text files
* Files with the suffix '.output' are model output files and contain the following columns:
	 - Time: timestep number (dimensionless)
	 - Rain: catchment rainfall (synthetic or measured) within timestep (m)
	 - Evaporation: catchment evaporation within timestep (m) (n.b. set to zero, see related publication) 
	 - QB: Modelled baseflow (subsurface flow) (m)
	 - QSOF: Modelled surface overland flow (m)
	 - Q: Modelled total flow (QB + QSOF) (m)
