Abstract:
The objective of this study was to to analyze characteristic of the quantity of water, analyzing characteristic of water quality and analyze characteristic of continuity water in DAS Tabunio. The data was taken in primary and secondary data. Primary data retrieval is performed during the 2-month activities including advance water height speed of the river flow, the water discharge measurement, and While in the transportation of sediment. Secondary data obtained from the relevant agencies such as water and then done a calculation of continuity . The quantity showed a discharge of water minimum is 0,237 m m3/second and a discharge of water maximum is 3,927 m3/second on the upstream . A discharge of water minimum is 0,321 m3/second and a discharge of water maximum is 2,568 m3/second the middle . A discharge of water minimum is 0,907 m3/second and a discharge of water maximum is 3,035 cubic meters per second on the downstream . The quality of water ( a charge sediment ) on the upstream recovery very low is as much as 4,949 tons year. Continuity of water ( flood ) of flood water downstream to the frequency of the flood 1 times in 1 year , to the center of with the frequency of as many as 1 times every year while on the upstream with the frequency of as many as more than 1 times in 1 year. In august that is 0,52 with a score of 1.00 and and empties to qualification for the recovery “being”; in september that is 0,325 with a score of 0.75 and went into in qualifying recovery “low
