Catchment constrictionsCatchment constrictionsClick on elements of the model or select from the tabs below Catchment constrictions are a narrowing in the width and/or depth of the catchment resulting in the formation of a catchment ‘throat’ which acts as a bottle-neck. Often groundwater above a catchment constriction is shallower due to the restriction of groundwater flow through the constriction point. There may also be a widening of the floodplain up-gradient of a catchment constriction due to the restriction of sediment flow through the constriction point. Unconsolidated sedimentary aquifers may provide a range of ecosystems with water required to support their faunal and floral communities, ecological processes and delivery of ecosystem services.
