The hydrology laboratory of Prof. Christoph Külls at Lübeck Technische Hochschule Lübeck offers education in hydrologic engineering, applied research and scientific services in the field of hydrology, water management and water quality studies. The focus of our work is on engineering hydrology and groundwater hydrology. We educate in and do research on groundwater flow and solute transport. The regional focus is the hydrology of coastal areas of Northern Germany and water-scarce regions. International projects have a focus on water management in regions with water stress taking into account water quality and environmental hydrology.
