Topographic effects on solar radiation distribution in mountainous watersheds and their influence on reference evapotranspiration estimates at watershed scale
solar radiation distribution mountainous watersheds
2010/12/22
Distributed energy and water balance models require time-series surfaces of the climatological variables involved in hydrological processes. Among them, solar radiation constitutes a key variable to ...
Reading the bed morphology of a mountain stream:a geomorphometric study on high-resolution topographic data
bed morphology mountain stream geomorphometric study high-resolution topographic data
2010/3/5
High-resolution topographic data expand the potential of quantitative analysis of the earth surface, improving the interpretation of geomorphic processes. In particular, the morphologies of the channe...
Distribution of bog and heath in a Newfoundland blanket bog complex：topographic limits on the hydrological processes governing blanket bog development
derived from digital elevation models bog development multinomial logit
2009/5/26
This research quantified the role of topography and hydrological processes within and, hence, the development of, blanket bogs. Topographic characteristics were derived from digital elevation models (...
On the calculation of the topographic wetness index：evaluation of different methods based on field observations
topographic wetness index field observations
2009/5/13
The topographic wetness index (TWI, ln(a/tanβ)), which combines local upslope contributing area and slope, is commonly used to quantify topographic control on hydrological processes. Methods of comput...
Topographic control of snow distribution in an alpine watershed of western Canada inferred from spatially-filtered MODIS snow products
snow cover fraction Quesnel River Basin snow cover duration
2009/4/28
A spatial filter (SF) is used to reduce cloud coverage in Moderate Resolution Imaging Spectroradiometer (MODIS) 8-day maximum snow cover extent products (MOD10A2) from 2000–2007, which are obtained fr...
