Damage varies depending on the site

The damage was slightly different between the two mega solar power plants because of the difference in the flow of the floodwater, according to Technical Yield (Fig. 8).

The water that flowed from the collapsed portion along the Tottabetsu River passed through the field and hit the fences of the mega solar power plant, eroding the soil and covering the beets and potatoes being grown (Fig. 9).

Vegetables were being grown in part of the field (bottom) on August 2, 2017 after restoration of the mega solar power plant. The light blue portion seen in the back is covered with blue sheets, and river restoration work was in progress in the area. (source: Nikkei BP)

Driftwood and crops were caught in the point area at the southernmost part of the mega solar site (Fig. 10).

The areas from the south to the southwest were severely damaged by driftwood and beets. Meanwhile, damage by driftwood and floodwater was comparatively minor in the area on the southeastern side. The pictures were taken on September 6. (source: Nikkei BP)
