We present a new class of efficient models for water flow in shallow aquifers, providing an alternative

to the classical but less tractable 3d-Richards model. Those models are tuned to have exactly the

same (dominant) behavior than the 3d-Richards model when the ratio ε =thickness over longitudinal

length of the aquifer is small. Thanks to a formal asymptotic analysis when ε → 0, those dominant

components of the flow are obtained in several time-scale situations.

The new class of models are then proposed, followed by their numerical approximation.
