ABSTRACT
More than 20% of Japanese live in the snowy area, therefore snow removal and snow control on roads have been essential since early times in Japan. In 1980, snow melting system without sprinkling ground water was developed in order to prevent land subsidence and to maintain ground water as a precious resource. Such snow melting systems are popular in the snowy area of Japan in these days because of its convenience, low running costs, and superiority in preservation of the environment. However, many pumping wells and many recharge wells are designed to be required in the limited area in some cases, and it is required to study or predict the influence of recharged cold ground water on temperature and level of the other pumping wells nearby. Simulation by numerical analysis supported by actual cold water recharge test in field, provides appropriate locations of each well with minimum mutual interference.
