The relationship between MRS data in Pearl River Delta of China and water yield

SNMR technology is the world's only direct search for new methods of geophysical groundwater. There are many examples that apply NMR techniques to research hydrogeological at home and abroad, but nobody use nuclear magnetic resonance techniques to calculate the water yield.This article is the case how to use the MRS data to calculate actual water yield. We made reference to the Pearl River Delta borehole data. At the same time transmissivity T and specific yield q is a linear relationship: T = D * q, this gives the range of D values, D is an element of (2,3.2),D value is tied directly to rocks. Nuclear magnetic resonance is successful to estimate the transmissivity in the Pearl River Delta. According to the borehole data the empirical constant C-p of the Pearl River Delta sandstone is Cp=4.7*10(-9).So we can use the C-P and MRS data to estimate the range of the water yield. It's a good reference for the actual demand, importantly, we can save money and workload.
