Meteorological observations have been carried out for different surface covers (grass, debris-free glacier and rock-covered glacier ice in Langtang Valley, Nepal Himalayas. Change in the daily mean lapse rate over debris-covered ice shows a significantly larger fluctuation compared with over debris-free ice. An analysis of the daily mean lapse rate reveals that a low (high) lapse rate appeared under dry (wet) conditions on the debris-covered area even though the opposite result was expected for the ...

The Gora Tabela Stage is defined by the deeply weathered Lower Till extending down to 3200 m a.s.l. The Langtang Stage (3650-3000 14C yr BP) probably corresponds to the greatest advance in the Holocene, followed by a series of smaller advances in the Lirung Stage (2800-550 '4C yr BP), and the ...

Surface flow velocities on the ablation area of the Lirung Glacier were calculated from the results of six surveys since 1989 to 1996. The annual flow speeds were about 6 m a -1 on the upper part of the ablation area near the icefall and the summer speeds were about one and half times faster than that. Around 2 km downstream from the upper part, the annual speeds decreased to about 2 m a -1 and the summer speeds were a little faster than that. Ice thickness was estimated, using the laminar flow theory, ...

Discharge from the Lirung Glacier per se was estimated for 6 months from May to October in 1996. The glacier was covered with thick debris, and the direct measurement of the melt rate at the surface is rather difficult. The discharge was hence estimated by measuring the water flow of a river out of the glacier, in which the water budget of a big lake located between the glacier and the observation site was taken into consideration. The discharge increased abruptly near the end of June, and showed ...

The authors made a topographical map of the ablation area of the Lirung Glacier, the Nepal Himalaya, using the result of the field observation for describing the morphological features of glacier surface. During the pre-monsoon season in 1996, 4538 points were measured for topographical mapping with a theodolite with an electro-optical distancemeter. The completed map was printed on a scale of 1/5500 with the contour interval of 10 m. Marked base points were left on the lateral moraines for future ...
