QuestionDo dams affect this resource?

Unit
Role
ImportanceDams are production resources in irrigation systems. Dams storage the water flow to produce hydropower energy or for water supply (Tang 1991). The presence of dams in the system may cause positive and negative effects on systems. Dams can provide water supply, energy, recreation, and flood control, but, at the same time, dams affect downstream hydrology and block the migration of species (Baxter 1977, Ligon et al. 1995).
DefinitionThis variable assesses if dams (reservoirs) are present in the system under study.
