| 總結: | The upstream Citarum watershed plays an important role in meeting the water
needs of the Greater Bandung area, but there have been several records of drought
events. Considering the population and water needs that continue to increase, a
study is needed to evaluate water availability, this study aims to determine the per
capita water availability index in each of the upstream Citarum Sub-watersheds in
2020-2099 and is divided into four periods. The data used are rainfall projections,
temperature projections, land use maps of the Upper Citarum watershed and
population data. The population projection method chosen is the logarithmic
method. The runoff discharge was estimated by the Thorthwaite-Mather method.
Furthermore, the mainstay debit calculation is carried out for a period of 20 years.
The mainstay debit is divided by the projected population to get a per capita water
availability index. The results obtained in the first period that the northern part of
the upstream Citarum watershed is included in the absolute scarcity category, while
the southern part is scarcity. In the fourth period, only the Cisangkuy Sub-
watershed did not experience absolute scarcity but there was still a scarcity.
Therefore, it is necessary to develop a sustainable water resources management
strategy. |
