| Summary: | analysis of monitoring wells at the site were compared with analysis results. Statistical analyses of long-term Flow both Flow Sensor locations accurately. components at the site. Differences in the response of correlated well. The azimuths obtained from both methods developed by Dr. Sanford Ballard at Sandia National dimensions. In the first phase of testing, Flow Sensor Flow Sensor data and piezometric analyses. Flow Sensor gradient analysis. The changes in velocity and direction of groundwater flow as determined from a piezometer gradient groundwater flow induced by the pump were evaluated using Hydrologic Field Site near College Station, Texas. The Flow interactions indicates that a direct and measurable linear Laboratories, were field tested at the Brazos River less permeable than upper portions of the aquifer. During location suggests that lower portions of the aquifer may be m/day at a depth of 18.3 m. Assessment of river-aquifer magnitude and direction of ground water flow in three of approximately 28.9 m/day at a depth of 13.7 m and 16.5 performance was assessed by comparison to piezometric predicted the approximate position of the pumping well at previous, long-term analyses were used in the piezometric pump tests in the second phase of testing, groundwater flow relationship exists between river stage and groundwater flow results and piezometric data from monitoring wells at the results from the Flow Sensors. In the second phase of River and the adjacent flood plain aquifer. Components of Saturated hydraulic conductivity values derived from Sensor data and piezometric data from the first phase of Sensors use a thermal perturbation technique to quantify the site were used to monitor interactions between the Brazos testing resulted in saturated hydraulic conductivity values testing, two aquifer pumping tests lasting 8 and 13 days were Two In Situ Permeable Flow Sensors (ISPFS), recently used to field test the accuracy of the Flow Sensors. vectors measured using piezometric and Flow Sensor data vertical groundwater flow to river stage at each Flow Sensor |
