The Kaidu River plays an important role in the water development and utilization Tarim basin northwestern China. In this study, we used a modified Budyko framework, which considered snowmelt to analyze attribute runoff change upper based on observations during period of 1960–2010. time series was divided into two periods: 1960–1995 1996–2010. contribution rate between these periods elasticity c...

Comparison of Degree-Day and Radiation base Snowmelt Runoff Model (SRM) for Estimating from Snow Melting

Model selection is an extremely important aspect of many hydrologic modeling studies because of the complexity, variability, and uncertainty that surrounds the current understanding of watershed-scale systems. However, development and implementation of a complete precipitation-runoff modeling framework, from model selection to calibration and uncertainty analysis, are rarely confronted. This pa...

Although most of forested watersheds in temperate and boreal regions are snow-covered for a substantial portion of the year, responses of biogeochemical processes under the snow pack to climatic fluctuations are poorly understood. We investigated responses of dissolved organic carbon (DOC) and surface water chemistry in stream and lake discharge waters draining the Arbutus Lake Watershed in the...

Remote sensing provides a means of observing hydrological state variables over large areas. The ones which we will consider in this paper are land surface temperature from thermal infrared data, surface soil moisture from passive microwave data, snow cover using both visible and microwave data, water quality using visible and near-infrared data and estimating landscape surface roughness using l...

Abstract In snow-dominated river basins, floods often occur during early summer, when snowmelt-induced runoff superimposes with rainfall-induced runoff. An earlier onset of seasonal snowmelt as a consequence warming climate is expected to shift contribution and potential flooding an date. Against this background, we assess the impact rising temperatures on snowpacks quantify changes in timing, ...

We are studying the chemical quality of dissolved organic nitrogen (DON) in a high-elevation watershed in the Colorado Front Range. Samples were collected over the 2000 snowmelt runoff season at two sites across an alpine/subalpine ecotone to understand how the transition between the lightly vegetated alpine and forested reaches of the catchment influences the chemical character of DON. Samples...

Abstract Soil Water Index (SWI) represents the conceptual water stored in soil and is calculated using a three-layer tank model with hourly precipitation. In Japan, landslide disasters are likely to occur when SWI an event exceeds maximum value of past 10 years; however, snowmelt-driven have not been considered yet. Using that simultaneously calculates runoff, we implemented snowfall-accumulati...
