Large floods are often attributed to the melting of snow during a rain event. This study tested how climate variability, snowpack presence, and basin physiography were related to storm hydrograph shape in three small (<1 km2) basins with old-growth forest in western Oregon. Relationships between hydrograph characteristics and precipitation were tested for approximately 800 storms over a nearly ...

Abstract Cold regions and snowing weather are widely distributed in Global, which caused a series of problems road safety, such as icy surfaces roads, frozen-thaw Circle damage, traffic jams. This research aims to improve the energy-efficient electric heating snow-melting tubes for solving snowy pavement urban roads. Numerical simulation in-situ testing experiments is used while temperature fie...

Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...

There has been a marked decline in the summer extent of Arctic sea ice over the past few decades. Data from autonomous ice mass-balance buoys can enhance our understanding of this decline. These buoys monitor changes in snow deposition and ablation, ice growth, and ice surface and bottom melt. Results from the summer of 2008 showed considerable large-scale spatial variability in the amount of s...

The study concerned the analysis of temporal and spatial variability floods in Republic Armenia (RA). While there are number reports on flood formation rivers RA, literature lacks results using nonparametric test to analyze this disastrous phenomenon. For that purpose, dynamics changes extreme maximum instantaneous runoff, as well air temperature precipitation database was evaluated compared be...
