Abstract:
Using the fissure-conduit media physical model, more groups of experiments are designed to study the change of sinkhole diameter influencing on the storage karst aquifer system and spring flow process. By analyzing data, regulating coefficient increased with the increasing of sinkhole diameter; with low recharge rates, the change of sinkhole diameter had little effect on the attenuation capacity of stage that fissure and sinkhole releasing water simultaneously, however, attenuation capacity obviously reduced with the increasing of sinkhole diameter under high recharge rates ; attenuation coefficient had nothing to do with recharge rates and sink hole diameter, about 0.0017 1/h; the product of regulating coefficient and attenuation coefficient of the first stage is negatively related to the recharge rates and is no related to sinkhole diameter.
