There are over 12800 large, medium and large reservoirs in Hunan Province, accounting for 1/7 of the total reservoirs in the country. In order to ensure the safety of reservoir projects, by the end of 1989, 11 large irrigation reservoirs in the province had carried out the observation of necessary test items according to the regulations. Out of 227 medium-sized reservoirs, 104 developed external deformation observation and 58 dam body tests Pressure pipe observation, 37 to carry out the observation of seepage flow.
