Sihwa Lake's working basin is 30 square kilometers. Rance's is 22.5.
And while Rance could take advantage of an estuary with a dam just 750m wide, Sihwa uses a 12.7km long seawall.
Sihwa's seawall was actually built for flood mitigation before SK realised it could work for power generations, building a 10km seawall solely for power generation sounds insane.
