The EU Water-JPI project titled “An integrative information aqueduct to close the gaps between global satellite observation of water cycle and local sustainable management of water resources – iAQUEDUCT” aims primarily at closing the gaps between remote observations of water cycle and local needs of information for sustainable management of water resources. Specifically, the objectives are to combine Copernicus satellite data with high-resolution Unmanned Aerial System (UAS) and in-situ observations to develop scaling functions for soil properties, soil moisture, and evapotranspiration at high spatial resolution meter scales. Regarding the use of UAS techniques, this project has very fruitful links and strong collaborations with the EU COST-Action “HARMONIOUS: Harmonization of UAS techniques for agricultural and natural ecosystems monitoring”, acting in such a way to gather scientists, having various backgrounds and experiences, around the common topic of enhancing the use of different types of environmental observations, harmonizing monitoring practices, and increasing understanding of interactive agro-hydrological processes.
Within the main objectives of this project, some integrated investigations were already started at MFC2 that is a small sub-catchment pertaining to the Alento Hydrological Observatory. The test site is located in the Upper Alento River basin in southern Italy, has a drainage area of approximately 8 hectares, and is representative of agricultural hilly lands subject to the typical Mediterranean climate.
The present contribution shows some preliminary results about an experimental protocol set-up to parametrize hydrological models in cost-effective and efficient ways. The protocol considers collecting soil physical, thermal, and hydraulic properties both in-situ and from UAS sensing. Basic and advanced pedotransfer functions (PTFs) together with spectroscopy are used to enrich the measured attributes with soft information, thus enhancing properly the input model requirements. Soil moisture sensor networks and a complete weather station provide data on the state of the system and boundary conditions. We envisage to apply two Richards-based hydrological models: the STEMMUS and HydroGeoSphere models.
