Daftar Isi:
- Now days, the availability of water is really needed by over populated and industrial areas such as East Java. Dam is a construction built to hold back water rate, so that it becomes a reservoir or lake. Therefore, the construction of dams in East Java is so significant. Brantas River Drainage Basin is one of surface water sources for the East Java area. Probable Maximum Rainfall (CMB) is a maximum rainfall that occurs in a rain station/area. The CMB calculation is very important, especially in the design of dam. Data analysis of daily rainfall was a parameter used to calculate the Probable Maximum Rainfall. The calculation of Probable Maximum Rainfall used Hersfield Method. The calculation result was processed to design an isohyet map. Isohyet map was useful to observe the high of rainfall in areas contained in map. The result obtained from the calculation of Probable Maximum Rainfall at every raining station in Brantas River Drainage Basin was 345.57 mm/day to 844.14 mm/day.
