Freshwater Update 55, October 2012
Welcome to Freshwater Update 55. This issue features some of the latest work from our Freshwater and Estuaries teams, Water Quality maps and information and River flow maps for Winter.
Latest news from the centre includes:
Estuary sedimentation is a continual natural process. Land slope, land use, soil type and rainfall all have significant impacts, and form a complex spatial pattern of sediment generation.
Intensive land use increases nutrient runoff to rivers, lakes and estuaries with adverse effects on ecosystems. Determining what combinations of land use and management enable the health and services of these ecosystems to be maintained or restored is a major challenge for councils.
NIWA scientists are presenting work at three national conferences in the next two months, the New Zealand Coastal Society conference 14th – 16th November, the New Zealand Hydrological Society conference 27th – 30th November and the New Zealand Freshwater Sciences Society conference,3rd – 7th December.
The three month flow map (on the right) shows that much of New Zealand experienced normal or above normal river flow conditions.
