The weirs were installed in trenches approximately 7 m long depending on the site characteristics , mm deep, and a minimum of mm wide. The upstream faces of the weirs were lined with PVC sheeting and backfilled with sand to prevent leakage.
The wing-walls were extended with sand bagging, PVC sheeting, and hessian as required by the nature of the specific site. Leakage at all sites was less than 0. At each site special gauging reaches were constructed and over 20 gaugings were undertaken to develop a rating curve calibration of stage height against discharge for each weir.
These rating curves would appear to be very accurate with little scatter about the best fit line. In the coming season the transducers will be sealed in anti-freeze and a rubber membrane to prevent freezing and the resultant change in calibration offset.

With regular maintenance this, however, was not a major problem last season. Climate Stations Two fully automated climate stations were established close to the hydrometric sites on the upper Miers and Adams Streams. These sites monitored air temperature, water temperature, humidity, incoming solar radiation, wind direction and speed, and soil temperature. Software Various pieces of software were written to calibrate the sensors and control the data loggers.
All this software appears to have functioned well under the conditions found in the Miers valley. Ablation Markers Three rows of five ablation poles were installed on each of the Miers and Adams glaciers.
The poles were placed in holes drilled 1. The position of each pole was determined from survey control sites adjacent to and above each glacier. Movement of the poles and the ice around them will be monitored in future seasons. Two of these stations were subsequently "doppler" fixed.
BMM21 is one of the doppler-fixed stations.
Five new stations were established to provide a triangulated control over the Upper Miers Valley. All lines to these 12 stations were observed and measured. One MWD lake level station was located and tied-into the above network. Five new stations were established above and along the south-east side of the Adams Glacier to provide control stations to locate ablation poles on the glacier surface.
All lines were observed and measured. Three similar stations were fixed above and along the south edge of the Miers Glacier.
Three stations were set-up to control each of the weir profiles and all lines to these stations were observed and measured. One station was set-up at the western end of Lake Miers to provide a control for levelling the lake surface. This level station was defined by repeated readings from BMM One station was set-up to establish the height of Keyhole Saddle. Nine stations were established to provide control for measuring the Adams glacier snout and five similar stations were established for measuring the Miers glacier snout.Epub Apr Epub May 9.
A notch is an opening in the side of a measuring tank or reservoir extending above the free surface. One MWD lake level station was located and tied-into the above network.
The locations of the stations on the rocky slopes above each glacier were described in detail and indicated by direction markers beside the glaciers. Stem Cells.
