The paper presents results of a pilot study of rainfall along the Siang basin that flows through the Arunachal Pradesh Himalayas in the northeastern Indian region. Using hourly station rain gauge data during 2001-2004, an attempt has been made to study spatial distribution of hourly rainfall and the relation between rainfall duration and diurnal variation during the summer monsoon season (June to September) over the Siang basin. The study has shown that most of the rainfall in the Siang basin comes from long duration rainfall events (an event that lasts longer than 6 hours). The long-duration rainfall events tend to have their maximum hourly rainfall around early morning, while short-duration rainfall events have their peak rainfall around late night.
