概要:
抄録:
In Saga City, Japan, there are castle moats and huge waterway system including rice fields. The waterways in rural areas of Saga City have much water, but that in the urban area, especially residential area has less water and very slow flow rate. Generally heat capacity of water is larger than that of ground. Therefore, the moat and waterways, which have less water flow, store thermal energy from solar radiation during daytime and release that to air above water surface at night. An urban waterway, which has low flow rate, has been considered to give no impact to urban climate in the past studies, but the castle moats and the waterways, which have low flow rate, are considered to affect urban climate in this study. This paper describes the measurement results of air temperature distribution of the moat of Saga castle and surrounding area in both summer and winter. Incidentally, lotuses are increasing by a vegetation recovery in the south moat of Saga castle from 2011. Water chestnut also began to grow thickly as the secondary effect. This paper also describes the survey and the experimental result about the water temperature rise inhibiting effect of the moat by these aquatic plants.

An abstract:
In Saga City, Japan, there are castle moats and huge waterway system including rice fields. The waterways in rural areas of Saga City have much water, but that in the urban area, especially residential area has less water and very slow flow rate. Generally heat capacity of water is larger than that of ground. Therefore, the moat and waterways, which have less water flow, store thermal energy from solar radiation during daytime and release that to air above water surface at night. An urban waterway, which has low flow rate, has been considered to give no impact to urban climate in the past studies, but the castle moats and the waterways, which have low flow rate, are considered to affect urban climate in this study.
