Professional monitoring has been conducted, including ground surface displacement monitoring, sliding body displacement monitoring at depth, monitoring of water table, GPS monitoring and manual inspections.
The layout of the measuring points is show in Fig.1.There is 3 monitoring section line and 6 surface displacements monitoring points, those are monitoring point ZG93 and ZG118 setting in June 2003, XD1 and XD2 setting in May 2005 and XD3 and XD4 setting in October 2005.Preliminary findings from sustained monitoring was showed that Baishuihe landslide was totally get worse in stability by the impact of water storage, water table fluctuation and precipitation, which presented the deformation characteristic of retrogressive landslide with obvious sign of surface deformation and big displacement variation[4,5].
These inputs are called lagged variables and other attributes, such as precipitation ,water level and temperature that are also relevant for forecasting the series can be added in the same fashion.Fig.3 displays the whole procedure of ODM SVM regression modeling.
The deficiency of the study is that data such as temperature, precipitation and water table has not been collected completely, and the data mining process carried out only based on displacement data.
The further work is building the model considered the displacement related data such as temperature, precipitation and water table and implementing the cross prediction process, and to validate the SVM model further on accuracy and reliability.

The latex is an anionic water dispersion of a styrene-butadiene copolymer with an antifoam agent.
After mixing, several specimens (10 cm and 15 cm cubes; 10 cm x 20 cm cylinders) were moulded and stored in a conditioning chamber (20ºC/95 % r.h.) for a day, after which they were demoulded and stored in water at 21ºC until testing.
Constituents Concrete [kg/m3] Cement 448 Sand 840 Course aggregate 840 Water 224 w/c 0.50 Methodology The research was performed in two phases: the first refers to the assessment of mechanical properties of concrete with varying percentages of both additives, and the second the analysis of the microstructure by SEM and XRD.
The chitosan has fixed electrostaticaly the calcium from Portland cement (chelation), which implies lower mobility of water, thereby increasing the resistance of the interfacial transition zone, increasing the tensile strength and promoting the pore refinement by the elimination of excess water of hydration.

So ADM1 can hardly be applied directly to engineering calculation and decision analysis without professional computer programs.
At beginning of the experiment, experimental sample of 1.5kg and seed sludge of 0.75kg were inoculated into reactor, then water was added to about 3L.
The temperature and flow of system was controlled at 33-37℃ and 10~12ml-1.min respectively by external circulating pool and water pump.
The water-in pump run 10min per 1h regularly.

A large number of grains with different orientations formed at the interface between the initial phase of the separator and the water-cooled chill.
The equiaxed grains nucleated and grown at the water-cooling chill were randomly oriented, which was demonstrated by the test results.
A large number of nucleation occurs when the metal liquid and water-cooled crystallizer came into contact as shown in Fig. 7.
The results showed that the number of grains decreased roughly linearly as the distance to the water-cooling chill increased.

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.

Abstract.
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

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.
