Abstract Snow production results in high volume of snow that is remaining on the low-elevation ski pistes after snowmelt of natural snow on the off-piste sites. The aim of this study was to identify snow/ice depth, snow density, and snow water equivalent of remaining ski piste snowpack to calculate and to compare snow ablation water volume with potential infiltration on the ski piste area at South-Central Slovak ski center Košútka (Inner Western Carpathians; temperate zone). Snow ablation water volume was calculated from manual snow depth and density measurements, which were performed at the end of five winter seasons 2010–2011 to 2015–2016, except for season 2013–2014. The laser diffraction analyzes were carried out to identify soil grain size and subsequently the hydraulic conductivity of soil to calculate the infiltration. The average rate of water movement through soil was seven times as high as five seasons’ average ablation rate of ski piste snowpack; nevertheless, the ski piste area was potentially able to infiltrate only 47% of snow ablation water volume on average. Limitation for infiltration was frozen soil and ice layers below the ski piste snowpack and low snow-free area at the beginning of the studied ablation period.

滑雪道雪消融与潜在渗透（Veporic Unit，Western Carpathians）

摘要 造雪导致低海拔滑雪道场外天然雪融雪后积雪量大。本研究的目的是确定雪/冰深度、雪密度和剩余滑雪道积雪的雪水当量，以计算和比较斯洛伐克中南部滑雪中心 Košútka 滑雪道区域的积雪消融水量与潜在渗透（内西喀尔巴阡山脉；温带地区）。雪消融水量是根据人工雪深和密度测量计算得出的，这些测量是在 2010-2011 至 2015-2016 年五个冬季结束时进行的，2013-2014 季节除外。进行激光衍射分析以确定土壤粒度，随后通过土壤的导水率来计算入渗。水通过土壤的平均运动速度是滑雪道积雪五个季节平均消融速度的七倍；尽管如此，滑雪道区域平均只能渗透 47% 的融雪水量。渗透的限制是在研究消融期开始时滑雪道积雪和低无雪区下方的冻土和冰层。
