The paper presents a catchment modeling approach for remote glacierized Himalayan catchments. The distributed catchment model TACD, 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 km2). Low laying reference stations are taken for temperature ...

Title of document: INTERREGIONAL DIFFERENCES IN STREAM ECOSYSTEM RESPONSES TO URBANIZATION: CAUSES AND CONSEQUENCES Ryan Michael Utz, Doctor of Philosophy, 2010 Directed by: Dr. Robert H. Hilderbrand Program of Marine, Estuarine and Environmental Science Stream ecosystems are profoundly degraded by watershed urbanization. Hydrologic, geomorphic, chemical and thermal adjustment following urban d...

Advance regeneration in 52 mature mixed-oak stands was analyzed and described. Red maple (Acer rubrum L.) was the most abundant species in the study area. Among oak (Quercus) species, northern red oak (Q. rubra L.) was the most abundant within the Allegheny Plateau physiographic province, whereas chestnut oak (Q. montana L.) was the most abundant within the Ridge and Valley physiographic provin...

The results of investigations on shaping the soil moisture ratio in mountain basin Mątny stream located Gorce region, Poland, are presented. A was defined as a given point to one base watershed. Investigations were carried out, using TDR device, for 379 measuring points an irregular network, 0–25 cm layer. Values fluctuated between 0.75 and 1.85. Based measurements, artificial neural network (A...

Spatially and temporally resolved observations of near-surface air temperatures (Ta, 1.5–2 m above ground) are essential for understanding hydrothermal circulation at the land–atmosphere interface. However, the uneven spatial distribution of meteorological stations may not effectively capture the true nature of the overall climate pattern. Several studies have attempted to retrieve spatially co...

Introduction The vegetation of great areas of Mixed Prairie has been destroyed by plowing. But even larger ones, still intact , have degenerated far from a climax condition. The almost universal cause for such deterioration, aside from drought, is grazing. The objective of this study has been to ascertain the changes in vegetation that have resulted from 60-70 years of different intensities of ...

Land has been the central issue to human society since the dawn of civilization. Primitive society took it as free gift of nature. Land and livelihood has become the intertwined focal issues in the epochal social transformation processes famous in different era of human civilizations which gave birth to the problem of ownership entitlement, the milestone of turning land as source...

Simplifications used in regional climate models decrease the accuracy of the regional climate models. To overcome this deficiency, usually a statistical technique of MOS is used to improve the skill of gridded outputs of the Numerical Weather Prediction (NWP) models. In this paper, an experimental synoptic-climatology based method has been used to calibrate, and decrease amount of errors in GFS...
