RISK ASSESSMENT GUIDE
The table below is intended to assist rowers and coaches in their pre-outing risk assessments. Please be aware that conditions can change in the course of an outing. Also, remember that if you start an outing during the flood tide, you may be out when the tide turns to ebb, presenting very different river flow conditions.
How to use this table.
-
Check the flow rate at Kingston Bridge. The numbers shown in the table refer to this data.
-
Check the tide status: Flood/None/Ebb. Read across to see which band the present flow rate sits and check if there are any restriction applying. We have set up Risk Scores from 0 to 5, with increasing restrictions. For convenience coloured yellow, orange and red.
-
In addition to the flow rate, you need to consider wind conditions and visibility as set out in the lower table and, if necessary, adjust the risk score – see the notes below.
Notes:
-
Add the risk score of wind/visibility conditions to the Flow Rate risk score to determine any rowing restrictions. For example, strong wind (2) with 150 m3/s flow rate (2) would give risk score of 4, which would suggest outings restricted to 8s only.
-
Combined risk score of 5 or over = no rowing.
Visibility guide: Eel Pie bridge to the western tip of the island = 180 metres. Eel Pie bridge to the TWRC hard = 100 metres.
