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.

18 Appendix A - Monitoring Requirements Objectives The monitoring objectives of Tindall Limestone Aquifer (Mataranka) WAP is documented in the monitoring programs under Monitoring Objectives as shown in the Surface Water and Groundwater monitoring frameworks in Diagram 1.0 and Diagram 1.1 respectively. The monitoring objectives for the snapshot measurements are based on surface water and groundwater monitoring requirements as documented in Table 1.1. Table 1.1 Measurement Surface Water Groundwater Water Level Gauge Board \ Survey Dip Tape Discharge Flow Measurement Flow Measurement at Springs Water Quality Field parameters (EC, temp, pH, turbidity and DO), Major Ions, Nutrients and Metals. Field parameters (EC, temp, pH and DO), Major Ions, Nutrients and Metals. The monitoring requirements for the snap shot measurements at each monitoring site are detailed in the Monitoring Requirements of Tindall Limestone Aquifer (Mataranka) WAP monitoring programs. Field Measurement Standards Water Levels The main factors that have an influence on the accuracy of water level measurements at surface water and groundwater monitoring sites summarised in Table 1.2. Table 1.2 Type Conditions Influences Description Surface Water Hydraulic Wave action Waves created during high flows, wind and or turbulence at gauge plates Instrument Location Point of measurement is a significant distance from gauge plates, especially during high flows. River Bend (outside) Water level higher at the outside of the bend. River Bend (inside) Water level lower at the inside of the bend. Velocity High velocities creates turbulence, etc. Turbulence Eddies \ turbulence created at gauge boards. Create difficulty in reading due to fluctuations in water level. Back Flow Back flow creates difficulties in reading gauge plates Site Sediment Sediment deposition at gauge plates. Gauge plates can be buried under sediment. Debris Debris deposited at gauge plates. Difficult to take readings without maintenance work
