Article in Icelandic about bank erosion and evolution at Blöndulón reservoir, N-Iceland

This article deals with wave erosion and evolution of the banks of the man-made reservoir lake, Blöndulón.

The bank evolution has been monitored quite closely since formation of the lake.

Calculations of the wave power are compared to erosion rates. Complicated relationship, different types of banks, episodic events, and relatively short time series 1997 to 2010.

But, as seen in the figure below, it is possible to see some correlation.

“Ölduorka” – Wave power (kWh/m), and “Rof” – Erosion (m).
