Description

Early dry season snapshot measurements were taken on the Roper River to establish water quality and quantity conditions at commencement of baseflow conditions. The snapshot measurements are used to: 1. Refine and calibrate the hydrological model used to assess resource availability and allocations. 2. Better define aquifer recharge/discharge zones along the river, and 3. Provide a dataset of comparable flow and water quality measurements at identical periods in the annual water cycle.

20 Steep slopes upstream should be avoided if possible. Avoid deep pools that can influence the flow Avoid prominent obstructions in a pool or excessive plant growth that can affect the flow pattern. Turbulence \ eddies must be avoided. Negative \ back flow must be avoided at all times. The abbreviations for the various factors as indicated in the above information (highlighted in bold) is shown in the gauging result tables indicating the various influences encountered at each site. Water Quality Instrument \ Sensor calibration. Compliance of water sampling procedure. The measurement location should be as close as practical to the mid-point of the stream. The sensors should be as close to the surface as possible. Turbulence (waves, eddies) at the surface should be avoided; the measurement point should be moved away from these areas as physical-chemical parameters will be affected. Standing water at the edges of streams should be avoided, as these are not representative of the stream. Deep pools with very low flow should be sampled as close as possible to the centre of the main pool.
