Upscaling of Slug Test Hydraulic Conductivity Using Discrete Fracture Network Modelling in Granitic Aquifers

摘要: The Indian sub-continent is underlain by hard rocks aquifers that are devoid of primary porosity and occupy more than two thirds the landmass. These highly vulnerable to pollution resource depletion because they most heavily exploited population for agriculture, industry domestic needs. aquifers, in general, consist three layers: weathered zone can be considered as a porous media, fissured/fractured zone, which heterogeneous, fresh basement generally any openings unless until some deep seated tectonic fractures present. Aquifers such geological settings are, therefore, very variable quality, inherently heterogeneous nature fracture networks. Due adaptation latest drilling technology India during last few decades, ground water has been on large scale. But this uncontrolled exploitation resulted an alarming decline levels. characterization flow storage these systems challenging task since transport processes different from those occurring matrix. Furthermore there extremely high degree contrast between hydraulic conductivity within short distances. An estimation groundwater resources only possible through parameters but it anticipated responses pumping tests performed well field cannot analyzed classical aquifer-testing methods assume homogeneous aquifer.
