In engineering practice some researchers like Jacob Bear calculated the height of capillary rise of phreatic water using Hazen formula[5], while Wessolek G.(2011) raised an equation-HPTF (hydro-pedo transfer functions) to estimate the quantity of capillary rise reaching plant root-zone within a year[6], Lu N(2004) Studied the capillary rise rate[7].
Other scholars studied the close relationships of human engineering activities such as capillary water and surface flow, rainfall, irrigation pumping, excavation of foundation pit, slope remake[9,10,11].
Physical property of test materials. (1) In engineering, an indicator called granularity composition is commonly used to describe soil particle according to relative content of different size particles.

TFC membranes contain minimum two layers of different (polymeric) materials, where a dense ultrathin layer of a highly selective membrane material is deposited on a porous support sublayer (as shown in Fig. 6) [36].
This is due to the inherent interaction between membrane material and the materials we want to resolve.

While the behavior of electrons in particular control most of the properties of materials, the nature and characteristics of every material can be investigated from first-principles, which means grounded on fundamental laws and without any free parameters, by solving the Schrödinger equation for the electrons in that material (based on the Born-Oppenheimer approximation: that the electrons move very fast in comparison to the nuclei that are always more stable, and are so lighter than the atomic nuclei that is feasible to consider fixed the positions of the nuclei while dealing with the electrons)[5].

Decentralised renewable energy projects have potentials to be cost-competitive in remote and large rural areas and could therefore play a key role in enhancing rural energy access in Sub-Saharan Africa.
For example, in December 2012, an engineer (French national) working with VERGNET Company on Katsina wind power project in Nigeria was kidnapped, which has brought the project to a temporary stand still.
The author is also grateful for all the reference materials used in this chapter.

However, a known key feature of those plants is that full-scale typical commercial capacities would require exclusive tonnage Air Separation Units (ASUs) supplying many thousands tons of gaseous oxygen (GOX) per day [1].
These units, hereinafter called as FULL-TSA, are inevitably featured by large vessels with large inventory of adsorbent material and high heating demand for regeneration.
SS then acts as principal purification step, leaving only ≈56 ppm mol H2O (16.5°C, 3.12 bar) to be handled by a small finishing TSA step, meaning ≈98.6% of water recovery for 98.59% of pressure recovery (ΔP=4.5 kPa), an excellent performance that is a key feature that makes SS-TSA superior to conventional FULL-TSA, since steam consumption is drastically reduced for a tiny increase on electricity demand, as disclosed in the utilities consumption summary shown in Table 1.

Abstract.
So, identifying the hydraulic connection between coalbed water and other groundwater is the key to successful exploitation of coalbed methane.
So along the river the shallow groundwater recharge the river. 2 Materials and Methods 24 groundwater samples were collected from different aquifers in June 2012 to determine the hydrogen and oxygen stable isotopes and carry out the water quality analysis.
When the organic materials and desulfurization microbial are coexist [20], the anaerobic degradation will be carry out: SO42-+2C+2H2O→H2S+2 HCO3-.

Abstract.
They are not commonly used by corrosion engineers; however, they can be a very powerful tool in cases where system hydraulics (pressures and flow rates) are a primary cause of a corrosion problem.
Information such as the exact layout of the system, pipe diameters, materials of construction, and pipe condition may be completely unknown, or the available data may be of questionable reliability.
Recent advances in engineering analysis software have enabled "live" sensor data to be automatically fed directly into hydraulic and water quality models.
