Results from this study revealed that nutrient export from actively developing catchments often
was affected more by climatic variation than by degree of land disturbance. However, land
disturbance tended to increase the rate at which nitrogen and phosphorous were exported from
the catchments and often resulted in first flushes for both total dissolved nitrogen (TDN) and
nitrate relative to the flow. Development also impacted the characteristics of organic matter
exported during storm events by lowering the aromatic fraction of organic carbon in the stream
during the periods of highest storm flows. Evidence of this was based on observed relationships
between the specific ultraviolet absorbance measured at 254 nm (SUVA254) and the storm flow
during periods of development for each catchment. Includes 8 references.
