Wetland processes are strongly influenced by hydrologic factors such as precipitation, surface runoff, and flooding dynamics. Anthropogenic disturbances to flooding regimes can thus substantially alter wetland habitat and biogeochemistry. The Kafue Flats, a large floodplain (-6,500 Km^) along the...

Lusaka sits on a limestone rock formation which makes recharge as well as pollution of groundwater very easy due to the presence of channels created by solution weathering. Informal/unplanned settlements where waste disposal facilities are non-existent are potential groundwater contamination...
