About this report
Quantifying residence times in estuaries (i.e. how long water is retained within different partsof these water bodies) can improve our understanding of the fate of discharges within estuarine systems. Until now, relatively little work has been undertaken to investigate howlong water takes to flow through estuaries on the Waikato region’s west coast. This report describes the development of a methodology, or proof-of-concept, for mapping residencetimes in the seven largest estuaries along the Waikato west coast, namely Waikato Riverestuary, Whaingaroa (Raglan) Harbour, Aotea Harbour, Kawhia Harbour, Marokopa Riverestuary, Awakino River estuary and Mokau River estuary.
