Hunger stone - Wikipedia
en.wikipedia.org

A hunger stone (German: Hungerstein) is a type of hydrological landmark common in Central Europe.

These stones were carved during droughts to mark the water level as a warning to future generations that they will have to endure famine-related hardships if the water sinks to this level again. One famous example in the Elbe river in Děčín, Czech Republic, has “Wenn du mich siehst, dann weine” (“If you see me, then weep”) carved into it as a warning.[1]

    Pumped irrigation from aquifers at a sustainable rate!

    We present the technical design, operational testing, and hydrogeochemical assessment of a stormwater-based MAR pilot site implemented in November 2024 in Hüll (Hallertau region, Bavaria, Germany), an area characterized by intensive agriculture, recurrent local flooding, and strong groundwater demand for irrigation. The MAR system combines a stormwater retention basin for buffering flash-flood dynamics, treatment units, and recharge via an infiltration well targeting a highly heterogeneous Tertiary aquifer.

    Initial results demonstrate robust system performance under variable stormwater conditions. The treatment units effectively reduce suspended solids and pesticide concentrations, enabling controlled recharge while minimizing risks to groundwater quality. Beyond quantitative water resource augmentation, the scheme shows potential qualitative benefits for agricultural groundwater systems.
