Roper River


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.

5 the impact of future water use are developed and calibrated appropriately, providing transparency and confidence in water licensing decisions. Monitoring data is critical for accurate assessment of the plan objectives. . The monitoring framework primarily consists of the following two categories. continuous monitoring of stage and discharge for the development of stage discharge relationships. This information is used to perform flow calculations and statistical analysis of catchment characteristics. snapshot monitoring of water levels and discharge at the end of the wet season when the hydrograph recession approaches base flow and the end of the dry season targeting annual minimum flow, normally May and October respectively . This information is used to calibrate the hydrological model and indicate what natural end of dry season flow conditions could be. Observations Measurements were carried out from the 26th to 29th May 2014 as recommended in the 2014/15 WAP monitoring program. Parameters collected include surface water level, stream flow, in-situ water quality parameters and water samples for analysis of additional parameters. Measurements were conducted at nine monitoring points along the upper reaches of the Roper River and tributaries where the river intersects the Tindall Limestone aquifer, with two additional sites further downstream beyond the aquifer extent (Figure 1). Scheduled monitoring requirements are summarised in Appendix A under monitoring objectives and field measurement standards. Field measurement standards are used to quantify the influences of measuring techniques and site conditions on the accuracy of datasets collected. Monitoring Sites Selection of monitoring sites is focussed on locations of major recharge from the aquifer to the Roper River. Currently only two of the snapshot measurement sites, G9030176 and G9030250, correlate with the broader NT hydrographic network collecting continuous river level and corresponding flow data.
