The aim of this paper is to present these technologies to the professional public.
The medieval Opatovice water channel, a water work which feeds the nearby lakes and ponds, the power plant water feeder system and the Elbe river´s flood-prone area are all located nearby.
The underground water level was steady during concrete casting.

It is used for the construction of sewage networks, water supply networks, and undercrossing works in urban areas.
The lithology of the zone comprised of soft clays and silty sands; the ground water level was determined at -6.00 m to -7.00 m from the ground surface.
The importance of professional studies and designs is emphasized in this directive.
Nowadays, tunnel construction is done with a high degree of automatic procedures and by high-skilled workers and professionals.
The capability to seal the machine protects it from the underground water pressures.

In Chinese traditional culture, there are five elements of nature: gold, wood, water, fire and earth.
“Water Region” is the place where the water tower is located.
On the surface of water “floating” some original trees, surrounded by a number of circular stones, like lotus leaves floating on the surface of the water, echoing “Water” theme.
“Fire Region” is the large-scale professional parking on the base, which has the core structure for the tall chimney.

The change of water level and discharge is reflected in the Table 1.
Data of water level and discharge are intercepted in relative intensive section.
Water level and discharge curve, a counterclockwise lasso, reflects the influence on water level and discharge of various factors in the period, as shown in Fig.1.
In formula above, input variable X of BP neural network is the factor of water level data. x is normalized facter of water level data.
Polynominal Fitting of Stage-discharge Curves Originpro 8 is a professional high-end charting and data analysis software, provides the square nonlinear fitting Wizard NLSF Wizard; this makes it easy to curve fitting.

The high toxicity of various effluents to water has resulted in governments enforcing ever tougher environmental laws limiting the treatment of water and wastewater, and the elimination of such effluents from water has been a major concern of environmental professionals for many years. [2].
The reaction was stopped with the sudden addition of a large amount of distilled water.

According to the test of professional departments, performances of GT materials (GT flexible waterproof material type Ⅱas an example) are shown in table 1 [1].
Preparation of GT rigid coating mixture ratio is the weight ratio ( paint: water = 1: 0.7), preparation of GT flexible coating mixture ratio is the weight ratio ( paint: water: GT slurry = 1: 0.5: 1.5), workers should reduce or increase the weight of water appropriately according to the climate and environment, stirring time shall not be less than 5min.
Powder and GT main liquid should be no water or rain, to prevent failure after water reaction.
, water high, records of storage time 12 Technical information Accident treatment, technical summary, experience summary, etc.
The corresponding inspection methods are: view check, water storage check, shower check, cutting card check, acupuncture check and so on.

Fig. 1 Automatic industrial washing machine (uncovered) According to the information provided by the sponsor, the podávacom devices are malfunctioning for the following reasons: - In the bowels of the drive gets water from the scrubbers, resulting in increased wear and stress on the pneumatic actuator
Fig. 4 The main force and torque load on the main drive Festo DGPL Equally serious is the already mentioned water condensing from water vapor along with chemicals that are found in the cleaning equipment in the industrial washing machine.
The fact that winch is located at the top of the motor cylinder, when the movement often has been the case, that is part of the condensation of water vapor, along with chemical solids get into the bowels of the actuator.
On the basis of the measured data and the views of experienced professionals who can carry out measurements to conclude that the test samples to maintain their properties and the mechanical point of view, there has been no significant change in the structure of the surface, or mechanical properties of the test material.

When carbon dioxide is dissolved into water, carbonic acid is formed.
Electrochemical corrosion may be generated when metal is in water.
However, with the development of oil and gas fields, the water cut is gradually increased.
A downhole wet carbon dioxide environment is composed of carbon dioxide and formation water.
