Irrigation water temperature and cold water damage of paddy

In 1996, a cold-water damage occured in the paddy field at downstream of the Unmoon dam. To study the cause and the preventive measures of the cold-water damage a field study was performed during the growing season of 1997. Field measurements such as water temperatures at reservoir, irrigation canal and in the paddy field were made. As a result, there was no cold-water damage due to the right irrigation water management practice in 1997. The cold-water damage is passible to happen, however, and the preventive measures were provided.
