But In recent years a series of unfavorable problems turned up: supply and demand of water are inconsistent; resource consumption increases extremely; environmental pollution and ecological destruction are increasingly serious; economic structural is contradicted; economic growth is comparatively extensive and so on.

The region belongs to the typical continental monsoon climate, less and uneven annual rainfall, frequent seasonal drought and lacking water; and there is similar economic and social development level in the region. 
Concerning the Yellow River Floodplain of North of Henan, the influence of natural factors mainly manifests in the aspects of water sources, landforms, climate and rainfalls
Furthermore, rural settlements are distributed along the Yellow River and its tributaries for the sake of getting water conveniently, which take on spatial form of belt type (as shown in Fig.6).

Through professional data, conversion software can put the project of the three-dimensioned entity into real practice directly with the detailed analysis of VRML simulation files.
Its water is draggling along Jiao village, whose supply gives emphasis on how to control flood with a vast capacity of 111.8 million water modules per 3 minutes.
The geographical position is rather important for Zhougongzhai reservoir's water levels, its variation ranges, and operational conditions.

The mixing water that used in this study was tap water.
Water absorption The water absorption value is a representative of concrete durability.
Water absorption test 2.1.3.4.
Then the sample was exposed to running water to demonstrate the water repellence. 2.1.3.5.

Finally, THI-water stream from LLS goes to a small atmospheric distillation column producing THI-water at the top and fresh water (99.99%) as bottoms.
For such pressure of 80 bar, the hydrate formation temperature for this NG field with such composition was estimated by the professional simulator using CSM method as 18.9°C, thus justifying the need for hydrate inhibition, since the seabed temperature was defined as 5°C.
The cooling demand was supplied by cooling water circuit, which in turn comes from sea water [9].
Water is added in the SS feed at 3:1 ratio of water moles per mol THI.
Water is also added into LLS at 4:1 ratio of water moles per mol THI in HPS gas.

Introduction Consider the flow of water through a porous and saturated medium (e.g. the soil), where a certain mass of a contaminant is found.
Then, the concentration of this contaminant in water decreases.

Many industries function smoothly by dumping the waste, toxic chemicals, biodegradable products frequently in the drains, which results in clogging of drains and thus preventing the water flow from the pipes.
Pipe cleaning and inspection robot is one of the new concepts of professional service robots.

Taking the grassland of the experimental base of water and soil conservation ecological inspection of the Pastoral Water Conservancy Scientific Research Institute to be subordinated to the Chinese Academy of Water Conservancy, the Chinese Ministry of Water Conservancy as the target of the study, the wind speed variation law and soil wind erosion rate and so on have been determined at different wind speed under different arrangement of different moisture content and different vegetation coverage of ground surface.
It is suggested based on the testing result that the number of grazing times and the number of herd of livestock should be lessened as far as possible during the dry season of winter and spring to avoid the shriveled vegetation being excessively trodden, even during the summer and autumn, the times of grazing and the number of livestock herd should also be properly limited for the sustained utilization and development of water source and pasture.

LEED has an integrated system, the entire system include professional certification, providing services support and training, implementation of third-party verification and so on, its development is completely controlled by market freely (or “free market”), also does not have any mandatory.
In the categories: the weight of three categories such as Sustainable Site, Water Efficiency, Energy and Atmosphere are all increased, Energy and Atmosphere have the biggest rise, which can shown that LEED have more attention to energy, source, pollution and sustainable development.
Table 2 The score changes of various categories from LEED version 2.2 to 3.0 1, Sustainable Site (14points→26 points) 2, Water Efficiency (5 points→10 points) 3, Energy and Atmosphere(17 points→35 points) 4, Materials and Resources(13 points→14 points) 5, Indoor Environmental (15 points→15 points) 6, Innovation in Design (5 points→6 points) 7, Regional Priority (0 point→4 points) Total (69 points→110 points) Fig.1 The weight of various categories between LEED3.0 and LEED 2.2 2.2 The comparison between the two versions on the content changes of various categories criteria
(2) The comparison on Water Efficiency: The weight of the category from 7% of version 2.2 to 9% of version 3.0(the score changed from 5 points to 10 points), the weight increased slightly.
In the content, it added a prerequisite of water saving, the aim is to make a minimum standard requirement on water saving, and the category of version 3.0 sum up the scattered subentry of version2.0, main content and standard did not change, the score of each subentry all doubled, which lead the assessment of water saving more quantitative
