Snow in a Very Steep Rock Face: Accumulation and Redistribution During and After a Snowfall Event
Terrestrial laser scanning was used to measure snow thickness changes (perpendicular to the surface) in a rock face. The aim was to investigate the accumulation and redistribution of snow in extremely steep terrain (>60). The north-east face of the Chlein Schiahorn in the region of Davos in eastern Switzerland was scanned before and several times after a snowfall event. A summer scan without sn...
متن کاملProcess-oriented Investigation of Snow Accumulation, Snowmelt and Runoff Generation in Forested Sites in Finland
This thesis summarises development and application of a hydrological model for simulating forest canopy processes, snow accumulation and melt, soil and ground water interactions, and streamflow routing. A motivation behind the model development is to outline a methodology for predicting the influence of land use changes on catchment hydrological processes. In addition, the development aims at p...
متن کاملModeling of Processes of Snow Cover Formation and Snowmelt
The chapter contains the general information on snow properties and main processes which occur in snow pack during cold period and during snowmelt. The models of hydrothermal processes and heat and moisture transfer in the dry and melting snow pack are described. The methods of calculation of snowmelt rate based on the energy budget of snow pack have been reviewed. To interpolate the spatial di...

متن کاملOn the evolution of the snow surface during snowfall
[1] The deposition and attachment mechanism of settling snow crystals during snowfall dictates the very initial structure of ice within a natural snowpack. In this letter we apply ballistic deposition as a simple model to study the structural evolution of the growing surface of a snowpack during its formation. The roughness of the snow surface is predicted from the behaviour of the time depende...
