River Infiltration Gallery construction in alluvial gravels.
(OP)
Constructing an infiltration gallery in a very active New Zealand river. Know how we plan to do it but interested in any cunning plans especially around dewatering solutions in a such unstable environment needing excavation to 3m below water level.

If the soil is sandy, this type of infiltration may not even work as the sand will foul the collection pipes.
A well screen installed with directional drilling may also be attractive. Have you considered this alternative.
