River Habitat Survey Technical Update.
April 2006.
IMPORTANT KEY NOTES FOR RECORDING RHS DATA.
PLEASE KEEP THIS UPDATE WITH YOUR FIELD SURVEY
GUIDANCE MANUAL.
Embankments
When you have an embankment along a river at a spot-check, record EM in
your spot-check bank modifications.
If the bank profile has also been
resectioned, record RS too (EM/RS).
In addition, record any other bank
modifications present, such as reinforced (EM/RS/RI).
Example.
In this photograph, you can see that the left bank is embanked (look at the
level of the car).
This bank has also been resectioned.
So you record both
EM and RS in your spot-check bank modifications.
(N.
B.
You would also
record RI for bank modification in this example – EM/RS/RI.
)
You will find that not all embankments have resectioned banks.
Some will
have natural-looking bank profiles and earth has been dumped on top of the
bank to create an embankment.
In these situations you do not record RS.
You record EM for bank modificatio
