Welcome to DT AGRO
Spatially Explicit Digital Twin of the Greek Agro-Hydro-System

The project’s overarching idea is to exploit the extensive expertise and information from previous and ongoing research activities of the research team to develop a spatially explicit Digital Twin of the Greek agricultural and hydrological system (DT-Agro) that will act as an effective tool merging at various scales (from farm-parcel to regional and country scales) the main components of the water-soil-food-environment-energy nexus..
Read more about usMain Ambition
The main ambition of DT-Agro is to combine recent developments in the simulation of the various components of the Agro-Hydro-System and the recently available Earth Observation open data sources with novel approaches and scientific advances on digital twins to promote their use as operational tools in Agriculture.
Main Components
- Spatially distributed continuous hydrological modelling. Hydrological balance components will be simulated in interaction to agricultural activities.
- Agrohydrological modelling involving water flows and storages in the soil plant atmosphere continuum
- Crop growth - crop production in interaction with climatic, soil, and farming practices factors
- Vegetation dynamics for naturally vegetated areas and non-agricultural areas
- Carbon stocks and fluxes in agricultural and naturally vegetated / forested areas
- Nutrient balance with emphasis on agricultural land and grazing lands.
- Erosion and soil degradation
Impact
Scientific impact
Data and knowledge generated through DT-Agro will be openly available and utilized by the scientific community (academia, researchers, and students in agriculture, earth and environmental sciences) and enhance their research activities.
Economic impact
Improvement of production with reduced inputs will result in financial viability of agricultural production businesses. Productivity will be increased with reduced environmental footprints with farmers acquiring critical information for informed farm management decisions
Societal impact
Information from DT-Agro will enable governments and local offices to support and benefit the agricultural sector and will support farmers and policymakers in the transition to more sustainable and resilient land, water, and agroforestry systems
Climate action
DT-Agro will provide the means towards EU efforts to tackle climate change and environmental-related challenges (e.g., biodiversity loss, natural habitats alteration, ecosystems restoration, landscape degradation)

SCS-CN parameter determination from observed rainfall runoff data. A critical review. Konstantinos Soulis, Stergia Palli Gravani, and Dionissios Kalivas Agricultural University of Athens, Natural Resources Management and Agricultural Engineering, Athens, Greece (soco@aua.gr) One the most difficult challenges in applied hydrology is predicting runoff in ungauged or poorly gauged watersheds. Thus, simple approaches for runoff estimation are especially useful in hydrologic applications. A simple, well established, and widely used technique for predicting the direct runoff depths of rainfall events is the Soil Conservation Service – Curve Number (SCS-CN) method. Due to its straightforward but well-proven approach, readily available and well documented environmental inputs, and incorporation of numerous variables influencing runoff generation into a single CN parameter, it quickly rose to prominence among engineers and practitioners. Tables can be used to identify the CN parameter values corresponding to prevailing soil, land cover and land management conditions. However, it is always better to estimate the CN value using observed rainfall-runoff (P-Q) data when available. Estimating appropriate CN values for additional soil – land cover conditions and additional regions is also critical for extending and updating the method’s documentation given that the SCS-CN approach is extremely sensitive to variations in the CN values.
