Sentence examples for tertiary water from inspiring English sources
The impact of such misclassifications on the estimation of the primary, secondary, and tertiary water type maps should be further investigated.
Weekly composites were assigned values of presence/absence of primary, secondary, or tertiary water type, and overlaid to generate an annual frequency map.
The water quality data (chl-a, TSS, KdPAR) was assigned to primary, secondary, or tertiary water type where that frequency of the water type was greater than 0.5, signifying the pixel was identified as a primary, secondary, or tertiary water type for at least 50% of the wet season.
Mean annual (ca. from December to April) in-situ values of chl-a, TSS, and KdPAR were mapped against annual frequency maps of primary, secondary, and tertiary water types for each of the 6 years (2007 2012).
