Existing Condition INDONESIA NESIA Existing Problem Floods : upstream (Bandung City) and downstream area (Kerawang etc) Drought : Upstrean and Downstream Water quality : Three cascade reservoir, Upstream (Bandung) and downstream (Kerawang etc). Water allocation : constraint/conflict among three cascade reservoir with different purposes priority (Hydropower, irrigation and raw water for industry/housing). Water pricing issue. Lack of data and reliable analitycal method.
