| Popis: | Discrepancies in time-space representation of indata and calibration/validation data cause potential misalignment between scales and potential misinterpretation of results in physically processed based modelling describing soil-plant-atmosphere-continuum (SPAC). This obstructs exploration of hydrological processes, linking natural and anthropogenic water infrastructure in catchments and landscape. To explore possible improvement in spatial representation in indata for hydrological- and SPAC- modelling, this paper presents a high-resolution dataset of hydrological functions in the agricultural landscape of Tidan, Sw Sweden. We firstly addressed the spatial representation of soil physical parameters, describing functions of soil water flows and storage. Secondly we derived tile drainage datasets from historical spatial maps. Lastly, we explored delineation and spatial location of streams, ditches and waterbodies to achieve datasets of improved water connectivity.The new datasets of hydrological landscape features enable better exploration of surface/subsurface flows and storage at catchment scale. The improved descriptors of natural and anthropogenic flow and storage can potentially serve to improve water quantity and -quality modelling under current and future climate- and hydrological changes The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) |
