My walk this week is another urban walk – in fact it is downstream of last weeks walk along the banks of the River Tawe. This time I am at the mouth of the river and looking around part of Swansea Maritime Quarter and SA1 area.
My starting point is the weir at the entrance to the marina. To its left (looking inland) there is one of two busy locks used by a wide range of vessels, but I was more interested in the patterns of water falling over the weir at different points.
In some places the water is very churned up following its descent over a structure of steps while further across the river the water is at first perfectly smooth as it falls over the curved surface of the weir. Further over again, where there appear to be rocks embedded in the curve of the weir, the water patterns begin to ripple and the froth on the lower surface of water appears to start climbing the back up the weir.
