The two maps illustrate the transformation of an area before and after the construction of a hydroelectric power dam, comparing the landscape in 1990 and 2000.
Overall, the area experienced significant geographical and infrastructural changes. Most notably, a large lake was formed due to the dam, which led to the disappearance of forests, villages, and farmlands, while new infrastructure like an electricity tower and a hydroelectric power station was introduced.
In 1990, the area featured a river flowing through a wide valley, surrounded by mountains and forests. There were two villages located near the river, along with agricultural land and forests in the central and southern parts of the area. A road passed through the valley, providing access to different settlements.
By 2000, after the construction of the dam, a large artificial lake had submerged a significant portion of the valley, including the villages, farmland, and forest areas. The only remaining village was located on the far eastern side of the map. Additionally, a hydroelectric power station was built at the southern end of the dam, with electricity towers and transmission lines also visible. The road was modified to adapt to the new water body, and a tourist resort was built near the lake, suggesting new economic activity.
In summary, the construction of the dam drastically reshaped the area, replacing natural and rural land with water and infrastructure.
