Abstract

Kali Putih (The White River) is located in Srumbung district, Magelang regency, Central Java, Indonesia. It is originated from
per slope of Merapi volcano, flowing to the Southwest direction. Kali Putih belongs to one of the most chanels where
frequently flowed by lahar of Merapi volcano. Based on geomorphological and geological traces found at the surrounding of
modern Kali Putih channel, this indicated that the flow of Kali Putih has undergone displacement several times. The position of
ancient river valley in the past has changed into the modern river valley in the present time. The existence of ancient Kali Putih
is exhibited by the presence of large dry valley morphology associated with volcanic blocks, gravels, and sand sized materials
with various shorting, representing the characteristics of lahar and alluvial deposits. In the present time, the
are currently used by local peaple for agricultural and fisheries land. This research was conducted
e the evolution of the ancient Kali Putih valleys, and the current river that acting as a collecting channel of lahars
and pyroclastic avalanches of Merapi volcano. By concerning to geological law of "the present is the key to the past" result of
this research can be used as a reference for studies related to volcanic disaster mitigation of the surrounding area.
