Samford Peri-Urban Stream Physico-Chemical Data 

Water quality parameters of the surface water from two permanent sampling sites on the Samford Creek, southeast Queensland, Australia, are determined. The parameters include water temperature, flow velocity, turbidity, major cations and anions, plus total inorganic and organic nitrogen and phosphorus. 

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging. 

This data is sampled to investigate the effects of land use change, in particular urbanisation, on the aquatic system in a peri-urban environment. Further, the data will be used to validate a catchment hydrological model of the area using the Soil and Water Assessment Tool (SWAT), which will simulate the effects of different land use scenarios on the catchment water balance and nutrient fluxes. 

Two permanent measurement stations were established on the Samford creek to provide continuous stream quality and flow data. These stations consist of a physico-chemical sensor (Sonde 6600 V2, YSI incorporated, Ohio, USA) to measure water temperature, pH, turbidity, water chemical composition and conductivity, and a velocity Doppler (Argonaut-SL, Sontek/YSI, San Diego, USA) to measure water flow and creek height. The sensors are connected to a CR800 datalogger (Campbell Scientific Inc, USA) and data is continuously averaged over 30 minute intervals. One station is located upstream from the junction of Samford creek and South Pine River and downstream from Samford village, providing water data from not only the village but also the entire Samford valley. The second station is located upstream of the village, and immediately below the conflux of the two SERF sub-catchments.
