Answer:
Loss of water from the evaporation and the transpiration in weed-covered of reservoirs can be six times higher than those from normal evaporation in open waters.
Step-by-step explanation:
- This means that more water exposed to the air and the problems of soil such as the sedimentation, siltation, waterlogging, and salinization. Along with the rise in humidity and temperature.
- Dam walls block the fish from migrating downstream and affect the dissolved oxygen levels of the water along with the physical properties of a reservoir that are not suited to the aquatic plants and animals that evolved with a given river system. The dams also contain invasive species that affect the environment.
