Strategic Study of CAE 2005, Volume 7, Issue 3,   Pages 53-58

Abstract:

It's pointed out by this paper that the priori knowledge of random rough soil surface is neededin soil moisture inversion by using passive remote sensing, so the precision of priori knowledge hassurface height distribution, soil temperature, and soil texture.Simulation result shows that it's feasible to invert soil moisture by neural network (NN) based onmoisture is allowable even there is some uncertainty on these three kinds of priori knowledge.

Strategic Study of CAE 2004, Volume 6, Issue 5,   Pages 71-75

Abstract:

This article mainly formulates that rainfall seeping makes the volumetric water of unsaturated soilchanging, and the water content relates closely to soil suction.That means soil suction changes with the stability of whole unsaturated soil slope, that is, the safetyBy monitoring the volumetric water condition changing of unsaturated soil slope, some information ofunsaturated soil slope stability can be obtained.
