Backfilling Filter Deployment for Groundwater Monitoring Well
This study composed the well-known criteria to design the grain size distribution of backfilling filter for groundwater monitoring well (GMW) under the sand and gravel layer. With an assumption of linear logarithmic scale distribution from D10 to D90, the coefficient of uniformity Cu can be formulated for D10, D60, and D90 corresponding to D15. Then, D0 and D100 can be obtained by linearity relationship. The method of backfilling filter deployment was then demonstrated by a practical application, which validates the procedures of existing filter design.
