Process-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 کاملEvaluating MODIS snow products for modelling snowmelt runoff: Case study of the Rio Grande headwaters
Snow-covered area (SCA) is a key variable in the Snowmelt-Runoff Model (SRM) and in other models for simulating discharge from snowmelt. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper (ETM + ) or Operational Land Imager (OLI) provide remotely sensed data at an appropriate spatial resolution for mapping SCA in small headwater basins, but the temporal resolution of the data is low and may...
متن کاملDistributed Mapping of Snow and Glaciers for Improved Runoff Modelling
Runoff in glacierized alpine basins results from the seasonal snow cover and from the glacier melt. Due to high resolution satellite sensors, it is possible to map snow cover and glacier areas in the basin of Massa-Blatten, 196 km2, 1447 4191 m a.s.l. Depletion curves of snow covered areas were derived in six elevation zones. In addition, the date was determined when the glacierice became expos...
متن کاملStatistical self-similarity of spatial variations of snow cover and its application for modelling snowmelt runoff generation in basins with a sparse snow measurement network
Abstract An analysis of snow cover measurement data in a number of physiographic regions and landscapes has shown that fields of snow cover characteristics exhibit statistical self-similarity property. This property is useful when, because of a sparse measurement network, the spatial variability of snow cover can be determined only for large enough basins. Small-scale variability of snow cover ...
متن کاملEffects of suburbanization upon snowmelt runoff
The influence of suburbanization upon runoff response to snowmelt and rain-on-snow inputs was examined for a small drainage basin in south-central Ontario. Modification of more than 50% of the basin area over a 14 year period led to a six-fold increase in the spring quickflow response ratio and an increase in the number of snowmelt events that generate appreciable quickflow. Anticipated changes...
