Groundwater abstractions

01. Water abstractions

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.

Effect/Impact on (including literature citations)

While surface water abstractions directly affect river flows, groundwater abstractions (both from shallow and deep aquifers) indirectly lower the discharge of streams and rivers, thereby decreasing the flow velocity and water depth in these water bodies. Acreman et al. (2000)[1] stated that large groundwater abstractions have a detrimental effect on rivers and wetlands. Additionally, status assessments of groundwater bodies in Denmark (Fyn region) and Scotland (East Lothian area), have shown reductions in base flow by 11% and 52%, respectively, due to groundwater abstractions (Henriksen et al., 2007[2]; Ward and Fitzsimons, 2008[3]).

Groundwater abstractions for irrigation can pose significant risks to groundwater conditions, and hence baseflow (Taylor et al., 2012). For example, in two sandy lowland catchments in the Netherlands, groundwater abstractions have caused a base flow reduction of 5-28% (Hendriks et al., in review[4]), even though the density of groundwater abstraction points for spray irrigation in these catchments is relatively low compared to some sandy catchments in the province of Noord-Brabant that show stream discharge reductions of 22% to 56% due to intensive spray irrigation (> 6 irrigation points per km 2 ) (De Louw, 2000[5]). Importantly, since spray irrigation occurs mainly during the summer growing season, it mostly affects groundwater levels and stream discharge during naturally low flow periods when water availability in streams is crucial for aquatic life.
