The test results manifest that the calculated valley undergroundrunoff by the K value obtained from the above stated two methods appear to very close.
试验结果表明，用两者得到的K值计算河谷地下径流量相当接近。

The results indicate that the water quality shows nonsignificant deviation among undergroundrunoff, the near little rivers, the near reservoir and the town rivers;
结果表明：集水区地下水、集水区旁小河水、水库水、县城河流水之间的水质无显著性差异；

The effect of enlarging volume by eroding of undergroundrunoff under the control of the principle of least resistance lays down a foundation for the formation of karst caves.
