Abstract:

In order to deeply understand the factors and mechanism of the flow process in a karst spring basin, a fracture-conduit media physical model and a numerical model are established according to the hydrogeological conceptual model in a karst area of Southwest China. Recharge, spring vent, sinkhole, and pumping well are selected as the impacting factors to the simulate spring flow process. The results of the experiments show three phases of spring flow process under the single rainfall test: increase, stability, and attenuation. The results also show that recharge has a very small impact on the attenuation coefficient with the same spring vent diameter; the corresponding attenuation coefficients with 3,4,5,7 mm diameter are 0.003 6, 0.006 7, 0.011 5, 0.012 9, a logarithmic relationship; the proportion of sinkhole flow is much larger than the fissure's. 2-3 mm is the transition zone of the larger fissure to the small cracks, the spring flows of the two types of media are quite different. The location of pumping wells is an important factor affecting the spring flow decay process, and the attenuation coefficients are decreased when the pumping well are located at near the spring vent, center of the model, and in the sinkhole.

Key words: fissure-conduit media, spring flow process, physical experiment, numerical simulation, sinkhole, pumping well
