Towards a dynamic representation of irrigation in land surface models (B05)

• Subject Area: Plant Cultivation, Plant Nutrition, Agricultural Technology ; Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 450058266

Water use for irrigation has a strong impact on water storages in aquifers, reservoirs, soil and atmosphere as well as on fluxes between the storages, in particular evapotranspiration. The main objective of B05 is to introduce dynamics in irrigated area and irrigated crops into land surface models, in particular differences between dry and wet years. Improved implementation of irrigation water use in the CRC IMS will help to better quantify human impacts on the water cycle and on energy fluxes and thus considerably contribute to the CRC’s key objectives.
