  abstract = {{T}he bare and cultivated indurated pyroclastic formations of the {E}quatorian {S}ierra ({C}angahuas) are strongly susceptible to pluvial erosion. {T}heir reincorporation to agriculture allows a partial control of ground loss and offers an alternative solution for agriculture management. {R}ain simulation gives information about imbibition, infiltration, runoff and erodibility. {T}he "quadrat point" method enabled us to observe the evolution of surface features (rugosity, crusting and sealing of porosity). {W}e make three campaignsof simulation just after the soil preparation, before and after the harrowing. {W}e observed the variations of hydrodynamic parameters and the evolution of superficial structural features. {A} rough soil preparation (coarse particle size) enhance the infiltration rate and reduce the soil loss. {O}n the contrary, a fine sized preparation weakens the roughness and seals the porosity by a superficial crusting. {T}hen the efficiency of the running water is enhaced.
