Conclusions
-
1.
The applicability of the model of the seepage passages to a description of the flow of water in coarse-granular materials for any seepage flow regime was substantiated theoretically and experimentally.
-
2.
On the basis of the two-term formula of resistance, for seepage in coarse-grained materials we obtained relations for calculating rubble drains for laminar, transition, and turbulent flow regimes in them.
