this study addressed the following objectives: 1) analyze
the water quality in lower order canals in representative areas and
compare the results with Vietnamese guidelines for drinking and
domestic use; 2) compare water quality in lower order canals between
inland and coastal regions and water quality attributes from main waterways;
3) identify the factors which explain the spatial variability in
surface water quality in lower order canals; 4) assess the effects of
tidal regime and seasonality on water quality; and 5) spatially visualize
water quality of thesewaterways to identify hot-spot areas of pollution.
