AB: Hyporheic exchange varies spatially as a result of the heterogeneity of aquifer and streambed properties. These flux patterns can be examined at a variety of scales, with the majority of recent studies focusing on reach scale investigations in order to obtain high-resolution measurements in a costly and time efficient manner. Understanding the processes occurring within the hyporheic zone should provide a step toward understanding the linkage between stream-basin dynamics. A field scale investigation of groundwater surface water interactions is currently underway in Nova Scotia, Canada using a variety of techniques including the deployment of temperature and level loggers within the stream, streambed, and monitoring wells at various locations in the watershed. Current efforts involve trying to rectify different estimates of groundwater discharge arrived at through hyporheic zone measurements, hydrograph separation and groundwater modeling at the aquifer-scale.
