will contribute to the resolution of questions such as: • What glacial fluctuations occurred in the BHM area throughout the last glaciation? • When did glaciation pre-dating the last glaciation occur? • Was the area ever covered by an ice sheet? • What is the relation Tibetan glaciation – uplift – climate variations? These are questions of special significance also for former periglacial conditions, as reconstructed glaciers and ice sheets had a fundamental effect on regional paleoenvironmental conditions.

144 Theme 4. <strong>Permafrost</strong> hydrology and cold regions water resources and land use Impacts of an Arctic Reservoir’s Regulation on Downstream Thermal Regime in Open-Water Season Baozhong Liu and Daqing Yang (Institute of Northern Engineering, University of Alaska Fairbanks, Fairbanks, AK 99775, USA) Abstract: In this study, based on the long-term (1950-1990/1992) stream temperature and discharge data, we investigated the impacts of the Vilui reservoir’s regulation on the downstream thermal regime in the open-water season. Results show that in the early open-water season (before June 30), the reservoir’s regulation has enhanced the downstream water temperature in a length through the mid Vilui River (maximum 4.7 o C) and down to the river mouth (maximum 2.3 o C). The decrease of discharge due to reservoir’s regulation is mainly responsible for the downstream water temperature increase in June, which was defined as the “indirect impact” of the reservoir. Analysis shows that the “direct (positive or negative) impact” of the reservoir, which usually causes continuous temperature increase or decrease along a distance of the downstream from the dam, could be possible in a distance from the dam, though much likely shorter than the mid Vilui River in the early open-water season. Results reveal that part of water temperature increase (around 1 o C) at the Vilui River mouth in June is caused by natural factors. In the mid open-water season (from July 10 to August 10), the reservoir’s regulation has reduced the downstream water temperature in a length through the mid Vilui River (about -2.7 to -0.6 o C), but not down to the river mouth. The “direct (negative) impact” is primarily responsible for the water temperature decrease in the mid open-water season in the mid Vilui River as the discharge increase is small compared to the pre-dam period. It is important to note that the water temperature in July at the Vilui River mouth is significantly associated with the reservoir’s regulation (discharge variation), although the long-term mean water temperature doesn’t show big change compared to that in the pre-dam period. In the late open water season (after August 20), the impact of the reservoir’s regulation cannot be through the mid Vilui River; thus the water temperature increase at the river mouth shows a local warming (maximum 1.9 o C), which is probably due to the reduction of influx from the non-regulated area. Key words: Vilui River, Reservoir Impacts, Thermal Regime, Long-term Change
