Porirua Stream at Town Centre
Cumulative sediment load, daily maximum flow and daily total rainfall for the 2019/20 monitoring season. Sediment load is predicted using a turbidity vs discrete suspended sediment concentration model that is updated annually, see Morar & Alberto (2018) for more information. The flow event lines represent the flow level at which we would expect n years before another event that size. Hover over or click on chart series to see specific values.Toggle between tabs to see sediment yields/loads of key events and annual totals per calendar year. Use the arrows ( ↓↑ ) next to the table headers to sort the data.
