Water tracing test in the Tianshengan region, China at low water level in November 1998
Janja Kogovšek, Liu Hong - (28/2,1999)
In 1998 a water tracing test at low water level was carried out within the international scientific co-operation between Slovenia and China in the Tianshengan region, Yunnan. This water tracing completed the knowledge achieved by water tracing during middle and high water level that was reached by water tracing tests in 1996 and 1997. From the injection point d towards the final Dalongtan spring the water drainage at low water level was three times slower than at middle water level. The water tracing also showed that water does not flow towards the spring 11 south-west from the injection point near the Shibanshou fault which remained an open question from previous water tracing tests.
