Sentence examples for drainage effects from inspiring English sources

Furthermore, by identifying drill-hole locations, or through numerical simulation, they directly remake the gas mitigation law and predict drainage effects under the design scheme.

The influence of adhesion and drainage effects between the beam and the halfspace surface is accounted for by considering "bounding techniques" for prescribing the boundary conditions at the interface.
