Tamar ADCP
G1
Station G is located next to St Johns lake which is an inlet into the River Tamar
for several streams. The deepest part of the channel is 26m and the channel has a
different shape to the other transects with a deeper channel located on the left
of the channel within the larger channel of water. This transect was taken at 11.25
which was during neap tide. The slowest flow rates are located in the secondary channel
which is within the larger channel. With flow rates of around 0.3ms-
D2
Station D is the location with the shallowest water depth with a maximum water depth
of 5.5m and a location just above the confluence of the Tamar and Lynher Rivers.
The flow rate at the river bed was 0.46ms-
B3
Station B is the most upstream ADCP measurement that we took and was taken at 13.21
during the neap tide. The flow rate was faster at the estuary surface with a flow
rate of 0.55ms-
E5
Station E is located below the confluence of the Tamar and Lynher Rivers, with the
transect taken at neap tide. The estuary bed has a depth of 14m and has a flow rate
of around 0.28ms-
F7
Station F is located just above St Johns lake. The estuary bed is very flat with
a depth of 16m. The transect was taken at 13.41 during neap tide. The flow rate is
slower close to the sea bed with a flow rate of around 0.1 ms-
H8
The water channel at station H is 16m at its deepest point. The flow speed is slower
close to the sea bed with an average flow rate of 0.143ms-
We took 12 ADCP profiles in total across the channel of the Tamar Estuary, however data for some of the profiles got corrupted so we only have data for 6 of the profiles. The ADCP profiles show the flow rate of the water through the channel. The higher velocities are indicated in yellow and red whereas the lower velocities are indicated by purple and blue.
