Abstract

The Noel Puames River is the main river in the Raknamo reservoir used for various purposes, such as irrigation water needs, raw water, fisheries, and others. In the rainy season, the Noel Puames River has enough large discharges, while, in the dry season, the Noel Puames River has almost no base flow. This study aims to determine the effect of climate change on rainfall characteristics in the Raknamo watershed. The methods used include the collection of rainfall data and watershed maps. The rainfall data were used by the Raknamo and Camplong rainfall stations for 25 years of observation resulting in the characteristics of rainfall decrease from time to time, especially the maximum daily rainfall. Annual rainfall tends to increase at Camplong station, but not at Raknamo station, which has the closest location to the Raknamo watershed. There has been a climate change in the Raknamo watershed as indicated by the Z value, which is not equal to zero (Z ≠ 0) although not significant except in March and September.

 

Keywords: effect, climate change, rainfall characteristics, Noel Puames.
