Piling snow depth measurement system

A piling snow depth measurement system, comprising:

• at least two heat quantity measurement apparatuses;
• a piling snow depth measurement apparatus;
• and
• a control apparatus,
• wherein each of the heat quantity measurement apparatuses includes:
• a snow receiving plate configured that falling snow piles up thereon;
• a heater device configured to heat the snow receiving plate until temperature of the snow receiving plate becomes a predetermined target temperature exceeding 0 degrees Celsius;
• and
• a heat flux density measurement apparatus configured to measure heat flux density transmitted from below to the snow receiving plate,
• wherein a first heat quantity measurement apparatus of the heat quantity measurement apparatuses is installed within a first location,
• wherein a second heat quantity measurement apparatus of the heat quantity measurement apparatuses is installed within a second location,
• wherein the piling snow depth measurement apparatus measures a piling snow depth of snow piling up at the first location,
• wherein the control apparatus computes a quantity of heat spent to melt snow falling on the snow receiving plate for each of the heat quantity measurement apparatuses, based on energy consumed by the heater device and a heat flux density measured by the heat flux density measurement apparatus, and
• wherein the control apparatus estimates a piling snow depth at the second location, based on the computed quantity of heat and the piling snow depth measured by the piling snow depth measurement apparatus.
