Flow field around vehicle sailing on still water is target need to be analyzed.
Flow field include two phases (water and air), free surface was captured by VOF[2] (Volume of Fraction) method.

An experimental study on co-pyrolysis of biomass and coal was performed in a tubular furnace for comparison of product (tar, water, gas and char) yields and composition.
The water content of liquid product was determined according to GB/T 2288-2008.
Water yield increases dramatically, compared with tar yield.
The increase of water yield could verify the postulate.

Mining Deformation Observation And Monitoring, The Discipline of Surface Movement And ‘Mining Under Buildings, Under Subways And Under Water.
The workers can also see the changing situations of the underground pressure, gas and water, which are closely associated with the process of mining on the screen clearly.
To Open Academies of Professional Higher Education For Mining Surveying.
To promote the development of mining surveying, facing the deepening education reform and widening absorbing students, it is necessary for academies of professional higher education to go to mining surveying and to absorb students from mines.
To open academies of professional higher education is one method for German to rise up mining surveying majors.

“A low water/cement ratio is also important; it reduces both the penetration of ions into surface layer of concrete and the water absorption of this layer.”
If water is kept on a steel smoother as on just washed glass, local increased water ratio has destroying effect on the quality of surface layer.
The modification is not relevant as site performance, but according to the opinion of interested professional community the modification with saw stir of steel ruler is representative and does not increase or decrease the result of deicing salt scaling resistance.
RESULTS Set A – water-tightness 25mm, 28 day strength 48,6 MPa with bulk density 2295 kg/m3 Set B - water-tightness 20 mm, 28 day strength 34,9 MPa with bulk density 2190 kg/m3 Set C - water-tightness 17 mm, 28 day strength 36,1 MPa with bulk density 2230 kg/m3.
The detailed analysis of the surface water absorption results indicates that specific value of deicing salt scaling test cannot be estimated from surface water absorption.

In the paper, it focuses on the water damage to building application area.
The detection temperature range of water leakage is not specific.
To express professional conclusion on defect severity and certainty by using simple different levels, the following rating and certainty level are defined.
Obvious water drops can be seen.
Detecting water in honeycomb structure by using pulsed phase thermography [J].

The phreatic water and perched water in the underground water have the great effects on the underground garage.
In abundant water period, water soares, and the runoff of water is large; while in dry season, water level drops, and the runoff of water is small.
New surface water is without impervious layer.
Visual MODFLOW 4.1 is an easy-to-use professional simulation software with complete function during the practical application of 3D groundwater flow and solute transport simulation which its application function complete and.

With the implementation of new rural development policy and development of rural economic in China, water pollution becomes a serious problem in rural areas, which has been the major factor that leads to watershed quality deterioration and ground water pollution.
Through professional organizations to provide operation, maintenance is conducive to ensuring normal operation of the facilities, and facilitates the implementation of supervision.
The system can be operated by the municipal departments, also can be managed by private water cooperatives.
Rural water pollution problems seriously affect the safety of drinking water, which restricted the economic development of rural areas [7].
Liu Junxin made a investigation of the villages and towns in different areas of our country, which in terms of the social economy, water environment, water drainage, sewage disposal, the demand will and constraints.

Water-based Mud (WBM) Preparation.
In contrast, the density of water is 1.00 g/cm³.

Lawn maintenance of golf course are very strict, even after the rainstorm, all stagnant water must all drain in 5 minutes.
Resources and environment problems of golf in China 2.1 Eexcessive consumption of water resources Water is the lifeblood of the golf course, golf course because of large area, The impact of the huge amount of water for irrigation required has always been widespread concern in society.
If the average value calculated daily 2600 tons, China more than 600 golf courses daily water consumption of 1560000 tons, annual water consumption of more than 560 million tons.
China 's per capita water resources are poor countries, especially in North China's freshwater resources shortage.
System file. 4.2 Improve awareness of managers on protecting environment Golf course superintendents should be responsible to society and the attitude of future generations, with professional attitude and scientific management system to solve ecological environment problem in development and management process.

The choice of mathematical model type has been described where the mathematical model represents the physicochemical character of the thickening process and allows estimating pulp water-yielding features at the stage of compression.
The research of the red mud pulp thickening process is aimed at creating the mathematical model, that admits detecting and assaying the pulp water-yielding features.
The water-yielding features of the thickened settling describe the specific settling resistance.
From the physical point of view, the thickened red mud settling can be represented as a system of solid particles with free moisture between them, where the particles are in touch with each other through elastic water covers, formed from the capillary moisture and producing the elastic resistance in the drainage process.
