| Description |
This Quality Assurance Project Plan (QAPP) will cover monitoring associated with the AWS component of this grant (WROCR-2123-ChCoNR-00025), which includes nine sites within the Icicle watershed. This QAPP describes the AWS monitoring program designed to quantify the effect of restoration actions on the channel bed elevation of incised streams and the groundwater storage effects that are expected to result from reconnecting an incised stream to its floodplain. Monitoring will include observational data collection of channel bed elevations, groundwater and surface water elevations, water temperature, and stream discharge. The anticipated effects of prospective restoration actions include increases in channel bed elevations and an associated increase in surface water elevations. Consequently, an increase in the magnitude of groundwater elevations as well as the duration of the elevated groundwater table, which are indicative of increased groundwater storage volume, are anticipated. We speculate that this approach could ultimately lower stream temperatures and increase baseflow. However, we do not anticipate that those effects will be large enough to be beyond the margin of measurement errors for the planned restoration and monitoring approach. |
