In this paper, we observed and compared the characteristics of phenophases, fruit-set patterns and burial mode of subterranean dispersal units, growth dynamics and the biomass allocations strategy in Ceratocarpus arenarius L.

Research on Several Legal Problems of Underground Policy;

Influences of ground water level changes to thin sand level of soft foundation;

Influence of cut-off wall in Changjiang dike on ground water level at its inside aera;

Study on the short-term earthquake prediction method with the data of ground water level;

Horizontal displacements in infinite slopes of cohesive soil due to raise of groundwater table;

Monitoring and Analysis on the relation between variation of Groundwater table and land Subsidence in urban area;

A simple method to calculate aquifer parameters through groundwater table and soil water content data;

Artificial neural network method for forecast of underground water level;

Based on Bishop′s effective stress formula,one-phase flow consolidation theory,and impedance function recursive method,considering the effect of underground water level,the dynamic response of a pile embedded in two-layer soil and subjected to a vertical load is theoretically investigated.

Using observation data of underground water level proves to be a comparatively reliable method for inversion analysis of seepage parameters for fractured rocks.
