The application in precipitation station layout with cone gradient method;

Determination of precipitation station is an important problem for the hydrological network design.

The reserch is evaluation of rainfall network,including control of rainfall stations,match of river distribution and rainfall network ,requiring of necessary rainfall stations both regional representative station and Xiaohe station, calculation raquiring of surface rainfall, necessary station requiring of regimen messages and flood report.

It is proposed that maximum economic benefit is considered as the index for the optimization of rainfall networks.

Making use of the observed discharge information, real-time correcting method is brought in rainfall network programming.

Impact of rain-gauge network intensity on monthly hydrologic simulation in different climatic zones

With the application of the data from rain-gauge stations in the experimental region of rain-gauge network for plum rains at home,the density of rain-gauge stations is studied with multi-hydrologic model set in combination of both the method of station sampling and the hydrologic simulation on the p.

Point interpolation algorithm is of important significance in analysis of rain-gauge station distribution,calculation of areal precipitation,and planning for rain-gauge net.
