| Abstrak/Abstract |
Rainfall data is vital in analysing hydro-meteorological disasters, e.g., floods,
landslides, or droughts. Currently, the location of climatological stations or rain gauges is
preferred in areas that require climatological data, such as airports and near settlements. On the
other hand, rainfall analysis for disaster mitigation purposes is more for remote areas, which are
often far from the nearest rainfall station. This study aims to obtain accurate rainfall data through
the placement of suited rain gauge locations and utilising community participation. The method
used in this study is a literature review. This preliminary study was held upstream of the Serayu
river basin, an area where it is usually challenging to access rainfall data. The references used
are information about tropical rain, how to utilise a rain gauge network, and how to take
advantage of community participation. The result shows that an Early Warning System should
be developed in line with determining the location of the rain gauge because each location has a
different rainfall threshold in each disaster. The placement of the rain gauge is strongly
influenced by the landscape, the altitude of the place as well as the slope and aspect. For this
study, the location of schools in remote areas is another parameter to determine the placement
of a rain gauge since school children will be involved in the community participation. |
