Drought in 5 categories, water source find this way

Hunan Daily All Media Reporter Feng Yongcheng Correspondent Liu Yanlong

At present, the province's drought continues and shows the development trend. Meteorological droughts appeared in 122 counties (cities, districts) in the province, and moderate hydrological droughts in 14 cities and states.

What kinds of drought are there? How to find water sources to do a good job of drought resistance? On September 9, the reporter interviewed relevant experts from the Provincial Department of Water Resources to teach everyone scientific drought.

There are 5 kinds of drought, and our province is the most prone to summer drought or summer and autumn drought

"Droughts have spring droughts, summer droughts, droughts, winter droughts, or droughts." Relevant experts from the Provincial Department of Water Conservancy said that the drought occurred during the Spring Drought Finger from March to May. Droughts that occurred from September to November, and the droughts occurred in the winter drought from 12 to February of the following year. Two or two seasons are continuously drought, they are called droughts, such as spring and summer drought, drought in summer and autumn, drought in autumn and winter, drought in winter and spring, or drought in spring, summer and autumn.

"It is easy to occur in our province. Summer or summer and autumn droughts. The current situation of summer and autumn drought has emerged." Experts said that the spring of Hunan was rainy, and the spring drought occurred less.

The most direct harm of drought is that crops are reduced to reduce production. When severe drought, it can cause people to drink water difficulty and easily cause fires. At the same time, it will also seriously affect ecological security, economic construction, production and life.

How to find drought resistance?

"When drought, we must immediately find water sources to fight drought." Experts said that common methods of finding water sources include the masses to find water based on experience, drilling water and electricity testing method.

Finding water with experience, including looking for water by observing natural phenomena, such as looking for water to find water with lush and humid plants that are looking for leaves; according to animal activity, water temperature, temperature, and ground temperature, find water; and find water according to the traces of water flow, etc. Essence

Drilling is divided into two types: manpower drilling and mechanical drilling. The depth of manpower drilling is relatively shallow and used for shallow wells; mechanical drilling is carried out by a professional hydrological geological team with a rig.

Finding water in the electricity test method is to understand the technical and methods of the ground rock conditions by observing the difference in conductivity of different rocks. This is also the current direction of the development of water technology.

How to ensure the safety of drinking water during drought?

"During the drought, we must pay special attention to drinking water." Experts said that we must establish awareness of water source, and the reserve water source should also be established to clear the water and pollutants around the water, separate the water sources of humans and animals, and ensure that drinking water hygiene is sanitary Safety. When the new water source is enabled, the water quality should be tested to ensure that the sanitary standards of drinking water in rural areas are compliant.

"Drought -drought water should first ensure living water, then ensure production water, first use surface water, then use water, saving water, then water adjustment, first use‘ live water ’, and then use‘ dead water ’.” Experts said.
