摘要高山流域的水平衡主要由融雪控制，融雪提供渗透，补给含水层，控制峰值径流，并负责下游大部分的年水流。准确估计雪水当量（SWE）是径流和洪水估计所必需的，但由于山区地形中雪积累、消融和再分布在一系列尺度上的变化，获得足够的测量值是具有挑战性的。我们已经开发出一种方法，从安装在雪地摩托车上的探地雷达（GPR）系统成像雪地层和估计SWE在很大的距离。我们将商用GPR系统（500和800 MHz）安装在雪地车的前部，以提供最大的机动性，并确保在原始雪地上进行测量。图像显示了详细的雪层结构，直到地面的雪深至少8米，使雪的积累和再分配过程的说明。我们估计雪的密度（一个）。
ABSTRACTThe water balance in alpine watersheds is dominated by snowmelt, which provides infiltration, recharges aquifers, controls peak runoff, and is responsible for most of the annual water flow downstream. Accurate estimation of snow water equivalent (SWE) is necessary for runoff and flood estimation, but acquiring enough measurements is challenging due to the variability of snow accumulation, ablation, and redistribution at a range of scales in mountainous terrain. We have developed a method for imaging snow stratigraphy and estimating SWE over large distances from a ground-penetrating radar (GPR) system mounted on a snowmobile. We mounted commercial GPR systems (500 and 800 MHz) to the front of the snowmobile to provide maximum mobility and ensure that measurements were taken on pristine snow. Images showed detailed snow stratigraphy down to the ground surface over snow depths up to at least 8 m, enabling the elucidation of snow accumulation and redistribution processes. We estimated snow density (an...
