Conservative tracer experiments can provide information useful for characterizing various subsurface transport properties. This study examines the effectiveness of three different types of transport observations for sensitivity analysis and...
Review: Groundwater flow and transport modeling of karst aquifers, with particular reference to the North Coast Limestone aquifer system of Puerto Rico [0.03%]
关岩溶含水层水流及运移的数值模拟——以波多黎各北海岸石灰岩含水层系统为例
