This paper presents a brief introduction of Kriging and its application to the estimation of spatial variability of aquifer elevation and initial piezometric head distribution in groundwater numerical modeling.

The effect of initial molten steel conditions and suitable methods for molten steel with different initial conditions were studied by natural decarbonization and forced decarbonization processes.

The formation and development of Ningxia initial water rights;

Research on Water Rights System and Allocation of Initial Water Rights;

Study on allocation of initial water rights in Tianjin Binhai New District

Ensuring agricultural water use should be insisted on during the original water right distribution, which applies with the basic principles of original water right distribution and is beneficial for trade of water rights.

Through the comparative study on the water right trade between our country and foreign countries,the key problem in the water right trade is concluded that is original water right allocation,the water right system and the price of water right trade.

Establishment and application of initial water right allocation model;

Democratic consultation has an irreplaceable value for procedure and essence in initial water right distribution of river basins, and its important content in "Good Management" framework of river basin.

By analysing different initial water level and cross sectional area of air chamber influence on hydraulic characteristics of water-diverting structure,it shows initial water level of air chamber obvious influence on pipeline pressure,the lower initial water level,the bigger action of lysis pressure wave transmission;adding cross sectional area of air chamb.
