Abstract

Mati river  located in Denpasar City with the length of main river ± 13 km and wide of watershed ± 32,5 Km2 is typical of urban river because from the upstream in Kapal Village area until estuary part in mangrove forest area Teluk Bay Benoa Forest Park its area of ​​flow has experienced very rapid changes to urban areas. Changes into urban streams cause higher pressure on rivers such as reduced border areas, garbage disposal and waste into rivers, limited access to inspection roads on the riverbanks and law enforcement linked to river border has not maximally reduced the pressure. The analysis shows that at some point especially on the bridge construction there is a narrowing of the width of the river. This condition triggers the occurrence of floods and puddles


This research uses qualitative and quantitative method with data collection both secondary and tertiary obtained from several related institutions.


The results indicate that the existing river management has not been well coordinated. Management still emphasizes the authority of each related institution (Public Works Department of  Denpasar City, Public work Department Of Badung Regency and Department  River Region of Bali Penida in their respective region). In terms of budgeting, it is directed more towards financing in terms of periodic maintenance such as landslide errors, and construction of stream alignment at the estuary. While budgeting for new routine maintenance is at the stage of study made by Department River Region Of Bali Penida. The management of Eco hydraulic based management is continuously divided into three stages: short term (0-5 years) in the form of widening Resimuka bridge, Buana Raya bridge, widening West Teuku Umar bridge, spreading  Umadwi weir, widening Nakula road bridge, widening Lavender hotel bridge as well as sedimentation dredging in the umadwi-estuary segment. Medium term in the form of law enforcement, planting bamboo vegetation in the upstream river channel and making the settlement  in Gatot Subroto to the upstream. Long term form of local law concerning the border, construction of river inspection road, settlement arrangement along river and recommendation of making of retarding basin at downstream of  Mati river  around Padangsambian with wide of 15 Ha.
