Management of Watersheds as a Planning, Monitoring and Evaluation Zone Unit for the Development of the City: A Case Study of Karangmumus Watershed at Samarinda City, East Kalimantan Province, Indonesia

The changing land use affects the social and economic characteristics and environmental issues in a watershed. To support sub-watershed management, land use scenarios and the level of community involvement must be improved. This research is a study to analyse and evaluate the condition of the Karangmumus watershed covering 365.25 km2 which is mostly located in Samarinda City, the capital of East Kalimantan Province. Research was conducted with various sources of data analysed using descriptive quantitative methods. In assessing the condition of a watershed, it is absolutely necessary to have debit data and other data to support the analysis and evaluation. In reality, currently the quantity and quality of flow data is still far from expected. This is due to the difficulties that cause the flow data collection process can not be done in all places, but only in certain watersheds. In the watershed monitoring carried out, there are still obstacles, one of which is the continuity of observation.
