On the Orgevai stream basins (parisian basin, Brie table-land), the drained grounds high proportion leads to the observation of an essentially delayed and hypodermic type of flow in streams, in spite of the relative imperviousness of the interested soil (30 % of clay), when the superficial water run-off is negligible. During heavy watering periods, the drainage system works in a generalized way and the yield function is near to unity, even for very light rains ; in the contrary, the transfert function keeps on amortized characteristics of an hypodermic flow. All of that confirms the rain seeping into the soil phenomenon primacy and its persistancy, even in the case of quasi saturations of the soil. The drainage system expansion in time been...
