Abstract:Remote sensing provides information on the land surface. Therefore, linkages must be established if these data are to be used in ground water and recharge analyses. Keys to this process are the use of remote sensing techniques that provide information on soil moisture and water-balance models that tie these observations to the recharge. The soil water content, variational law and utilization rate of soil water for crop were studied from our experiments in 1997~1998. Soil water in 0~50cm, spectral and TM/NOA...
