Mention one cause of not having proper development of hydroelectricity in Nepal

Flooding leading Erosion

Explanation:

Although, hydropower is considered as a renewable clean energy, dam closure, influence within the downstream river and connected ecosystems have consequent impacts on hydropower production. Nepal's topography offered more RoR types of hydropower and has more risk of landslide, flooding, GLOFs, LDOFs, and flash floods.

Large quantities of sediment acts as barrier for economic exploitation of hydropower resources.

Explanation:

Nepal is blessed with high potential for hydropower. Glaciers in the Himalayas, rapid monsoon rainfall and local topography are the reasons for the hydropower plants.

But the large quantities of sediment are found in Himalayan Rivers that acts as barrier for economic exploitation of hydropower resources. Influence of climatic, tectonic and human activities causes Erosion.

The power plants in this area gets affected by excessive sediment in rivers that decreases the life of plants. The reservoirs get filled up or by erosion of turbine elements.
