Research advances on multi-medium flow model for karst aquifers
-
Abstract
Numerical simulation techniques have been widely applied in the field of groundwater flow model-ing,providing a scientific basis for reasonable exploitation and utilization of grounder water resources.This paper reviews the main methods and recent advances in groundwater flow modeling of karst areas.The prin-ciples and methods for the SWMM,UGRFLOW,CAVE and CPF models are introduced and the main prob-lems in actual application are discussed.Traditional finite difference methods are not adequate to simulate water flow in karst aquifers,with their heterogeneity and complexity.Taking into account the characteristics of karst aquifers,a model was developed with a dual porosity medium and triple medium,producing good re-sults for depiction of the groundwater flow field.Problems in actual application,such as how to account for wide fissures and conduits and application of the model,are discussed.From the perspective of numerical simulation of karst aquifers,the structural and flow characteristics of wide fissures are very important.To improve the accuracy and practicality of numerical models,the pipe flow module and flow algorithm should be revised.-
