Executive Summary

Primary Findings - Summer 2019 Field Season

The 2019 summer field season of the CSL Heron, extended from April to October and involved deploying a variety of sensors across the active part of the Squamish prodelta.

Wot we've done so far.....

April -
recovered two of the pressure gauges.....

Deployed three hydrophones - all now with acoustic releases - all now with 192 kHz logging...

Survey updates...

June to do:

First LEG :

resurvey as always..
daily surveys along axis

Extra buoy upstream with 1200 kHz ADCP
download 600 kHz ADCP and add extra battery pack and frame

recover, download and redeploy the 3 x hydrophones.

fish for the one un-recovered pressure gauge.

Deploy 4 more pressure gauges.

Second LEG :

resurvey as usual

deploy the DDS 9001
daily surveys along axis

2020 field program thoughts

As always, the long term, the aim of continuing the Squamish monitoring program is to :

A - extend the monitored period to see long-term morphological evolution (channel initiation, growth, avulsion etc..)
B - develop improved technical methods to more completely understand the full evolution of flow from initiation to deposit

haven't yet thought what we will do for 2020 as depends on 2019 results. ....
