%X in this research a hydrologic design is defined for infiltration ditches in forest works, for arid and semiarid regions in central chile. in this context, four plots were evaluated (hidango, in o'higgins region; name, in maule region; and llohu¨¦ and manzanares, in b¨ªo-b¨ªo region), including two types of infiltration ditches, established in may 2002, linked to a plantation of pinus radiata. each plot has a unit witness, which does not present any type of soil treatment. two types of ditch infiltration were differentiated in width; one of them showed 20 cm and the other 30 cm, but both possessed the same height of 30 cm. the first one was named ditch type 1 and the other ditch type 2. results showed that the application of the new hydrologic design for infiltration ditches is very useful when facing extreme events. also, ditches showed a greater surviving rate for p. radiata, being more evident in ditch type 1 that defines less distance between ditches. however, in two plots there is evidence that witnesses showed more biomass than ditches did, although it is not always significant from a statistical point of view. finally analyzing another type of variables, such as nutrition plant or genetic conditions, becomes necessary to be considered in future research.
