“…Table 1 summarizes the main characteristics of the investigation area. Several sets of moraines occupy the valley bottom, which have been attributed to the Little Ice Age, Neoglacial and Late glacial (Heuberger et al, 1984;Ono, 1986). Boulders and scree cover the steep slopes and high plateaus, while the occurrence of forest and grassland in the lower altitudes with less steep slopes along the river is limited to 1.5% of the catchment area.…”

Abstract. The paper presents a catchment modeling approach for remote glacierized Himalayan catchments. The distributed catchment model TAC D , which is widely based on the HBV model, was further developed for the application in highly glacierized catchments on a daily timestep and applied to the Nepalese Himalayan headwater Langtang Khola (360 km 2 ). Low laying reference stations are taken for temperature extrapolation applying a second order polynomial function. Probability based statistical methods enable bridging data gaps in daily precipitation time series and the redistribution of cumulated precipitation sums over the previous days. Snow and ice melt was calculated in a distributed way based on the temperature-index method employing calculated daily potential sunshine durations. Different melting conditions of snow and ice and melting of ice under debris layers were considered. The spatial delineation of hydrological response units was achieved by taking topographic and physiographic information from maps and satellite images into account, and enabled to incorporate process knowledge into the model. Simulation results demonstrated that the model is able to simulate daily discharge for a period of 10 years and point glacier mass balances observed in the research area with an adequate reliability. The simple but robust data pre-processing and modeling approach enables the determination of the components of the water balance of a remote, data scarce catchment with a minimum of input data.

“…For the examined sites parent material, biosphere, and the climate, which largely depends on alitude and topography, are nearly the same. Time related differences are confirmed by studies about moraine deposits and the Pleistocene and Holocene history of landscape and climate in our working area (Heuberger, 1984; Shiraiwu and Wuranabe, 1991; Buumler et al, 1996). And in agreement with their results concerning the soil age the intensity of weathering and changes in clay and fine silt evolution increase in the order Ll<L2<L7<L8 representing soils developed from moraine deposits of "Little Ice Age", Late Holocene, Middle Holocene and Early Holocene origin.…”

Chemical and mineralogical properties of a soil chronosequence in the high mountain zone between 3857 m and 4120 m a.s.1. in Central Nepal (Langtang valley) are presented. The soils have been developed in moraine deposits which consist of acid gneisses. They were classified as Entisols, and Spodosols. XRD analyses of the clay and fine silt fraction show increasing changes with distance from the recent Lirung glacier, depending on the time of deposition, resp. soil age. Alteration of illite to interstratified minerals and to hydroxy-Al interlayered minerals or pedogenic chlorite with increasing soil development could be observed. The interstratified minerals could be identified as random and regular illite-interlayered vermiculite mixed-layer minerals. Intensification of the X-ray signals of the fine silt fraction is given compared to the clay. With increasing soil development differences between the clay and fine silt fraction seem to increase. Indications are given of interstratification of the mica-pedogenic chlorite and chloriteinterlayered vermiculite type in the more intensively weathered soils.

“…Die daraus nach der Abkühlung entstandenen speziellen Metamorphite mit Deformations gefügen wurden in ihrer lokalen Ausbildung früher mit Hyalomylonite (Scott & Drever, 1953), heute als Friktionite bezeichnet. Durch den Vergleich dieses in mineralogischer Ausbildung und Genese wohl seltensten Gesteins der Erde mit dem Köfelsit avancierte der Bergsturz von Langthang zum idealen Komplementärbefund für den Bergsturz von Köfels im Tiroler Ötztal (Heuberger et al, 1984).

ZusammenfassungDie gewonnen geologischen, geomorphologischen und geotechnischen Grundlagenerkenntnisse an der im Kristallin weltweit gewaltigsten und einzigartigen Großmassenbewegung des Tsergo Ri im Langthangtal des zentralen Nepal Himalaya entschlüsselten nicht nur den chronologischen Ablauf der Paläo-Ereignisse vor Ort, sondern können auch direkt auf eine Einstufung des rezenten Gefahrenpotentials dieser Gegend und ähnlich geotektonisch-lithologisch positionierter Bereiche des Himalaya und der Erde angewendet werden. Dies konnte vorerst am Beispiel weiterer, kleinerer Bergstürze im Langthangtal selbst, im Kristallin des Annapurna Massivs und mit einem Vergleich zu einer Felslawine in Zentralchina bestätigt werden.
