CHUNG
KHUNDAM
Event description
The advance of the Chung Khumdan
glacier - a tributary of the Shyok, had formed an ice
dam. The 1929 outburst flood of Chung Khumdan glacier
was monitored from near the glacier for over 1`500 km downstream. Gunn (1930)
estimated the reservoir to have contained almost 1350 Mio m3. Some
300`000 m3 of ice were also carried by the flood and stranded on
large blocks in the valley below the dam. At the peak of the steeply rising and
falling flood, water discharges in excess of 22`650 m3/s were
indicated, which is the largest discharge ever measured for the entire upper lndus at Attock.

Remarks
The only information available for 1926, 1929, and
1932 Khumdan outbursts is that breaching began
through subglacial tunnels, but then carried away the
entire thickness of ice above (Khan 1994).
