General description
Groundwater over-abstraction can lead to decline in groundwater levels within aquifers and drying up or causing severe flow reduction in rivers. Surface seepage from aquifers supports groundwater-fed ecosystems such as wetlands and springs. Riparian vegetation affected by declining phreatic levels rapidly shows signs of water stress, leading in extreme cases to widespread riparian plant death.
