Is the megadune sustained and developed by lake water, or the development of megadune cause the formation of the lakes?
Water has special significance to the desert area and the development of water recreation has great limitations.
But, taking the water amusement as auxiliary means has a good effect. ⑥Agriculture sightseeing projects are weakened.
Desert expand camp is mainly about desert exploration and outward bound which combine the soft adventure with low risk and hard exploration with professional level.
Both the public and professional explorers can feel infinite pleasure.

Water damage of asphalt concrete pavements has been one of the major distresses in
highway engineering.
Introduction Water damage of hot mixture asphalt (HMA) is a leading mode of premature distress of asphalt pavements.
Bleeding, cracking, rutting and raveling are typical distress types of asphalt concrete (AC) pavements and the existence of water consequentially accelerates the initiation and development of all those types of distress, which is usually called the water damage of asphalt pavements [1].
As the value of compact degree is lower, the value of porosity becomes higher and as a result, water enters easily in road surface structure.

The temperatures measured on the skating rink surface using thermocouples is impossible due to the larger diameter of the thermocouple bulb compared with the air- water surfaces thickness.
Fig.4 Temperature distribution at τ = 120 min Fig.5 Temperature distribution at τ = 180 min Initialized parameters in the mathematical model were: water temperature on the skating track tw = 10 °C , air temperature at the water free surface tair = 10 °C , temperature of the refrigerating agent inside the pipe tr = -10 °C, convection coefficient in the pipe a = 550 W/m2K, air convection coefficient on water surface a = 15 W/m2K, heat flow rate on the track foundation board q = 10 W/m2.
Thus, for the X and –Y directions we have a steep temperature decrease, and on Y direction a slower decrease due to the water surface convective heat flow.
One advantage of using ThermaCam Researcher Professional 2.8 software is that the temperature can be measured in specific points (SP1, SP2,…., SP5), or along a line which intersects several areas (LI 01) The points and line were placed on the study area so that their positions correspond to points coordinates on the numerical simulation model geometry (Fig.7) .
After the complete solidification of water, temperature differences drop, showing a decreasing cooling load and a stable operation of the refrigeration system.

The mobile phase consisted of methanol, water and acetic acid (60:40:1, v/v/v) and was pumped at a flow rate of 1.0 mL/min.
Water was purified in a Milli-Q system (Millipore, Bedford, MA).
Mixtures of methanol water and acetic acid were examined as the mobile phase and its composition was optimized.
The ratio of methanol, water, acetic acid was was 60:40:1 This ratio obtained a good resolution of Hypocrellin A and B.

In order to avoid sinking the ship, its driver decided to run aground in order to intervene to evacuate water from the engine room and plug the water hole.
Water hole board port CM, view from outside [10] Fig. 9.
The operational and professional intervention of the crew led to avoiding major pollution, given the amount of cargo transported and the impact it would have had in case of a sinking. [5] Fig. 10.
It must be possible to keep oil waters from exploitation on board.
The consequences of water pollution are felt not only at the level of the flowing waters where the discharge of pollutants takes place, but also hundreds of kilometers from the place of leakage, because the waters of rivers, rivers can infest large areas, finally reaching sea level.

Generally, only firefighters and professional rescue teams are allowed to conduct rescue.
But for fire, smoke and other complex conditions, even the professional firefighters cannot make the optimal rescue activity in the first time easily.
(3)Emergency rescue for major toxic and harmful liquid leakage accidents Major toxic and harmful liquid leakage accidents include the accidents with the direct leakage of toxic and harmful liquids and pollution accidents with the firefighting waste water in the gas leakage or fire explosion accidents overflowing into the natural water.
The traditional water sample test may adopt the point test to estimate the pollution situation of the whole area, which has the certain limitation and one-sidedness.
The multispectral image is generated through the multispectral imager of the system, intuitively and comprehensively monitoring the environment quality conditions of surface water and providing the thematic maps of information on water eutrophication, water bloom, water transparency, suspended solid and pollution conditions of outlets to achieve the goal of detecting the water quality pollutants.
