APPLICATION OF KAGAN-RODDA METHOD FOR RAIN STATION DENSITY IN BARITO BASIN AREA OF SOUTH KALIMANTAN, INDONESIA

This study discusses the application of Kagan-Rodda method for evaluating the density and distribution patterns of rainfall stations in Barito Basin Area (BBA), South Kalimantan Province. The existing conditions revealed that there were 3 rainfall stations which have difficult conditions according to World Meteorological Organization (WMO), i.e. Sei Tabuk Station, Binuang Station and Jaro Station. Based on the Kagan-Rodda net planning, it was revealed that the designed rainfall difference for each definite recurrence time is relatively small. The determination of new rainfall station locations based on Kagan-Rodda method can be applied in Barito.
