VAZÕES AFLUENTES EM TRINCHEIRA DE INFILTRAÇÃO DOMICILIAR

摘要: The unplanned soil sealing hinders the process of infiltration rainwater in residential settlements, which favors increase precipitation, and reduce response time basin. In this context, certain flow control techniques, such as trenches are consolidated an alternative to alleviate difficulties related volume water precipitated, especially conditions exceeding volume. This work aims analyze inflows non-induced events with monitoring a trench for 5 months continuous urban lot. device has capacity up 5.7 m3 area 8.8 m2 composed geomanta, gravel, earth vegetation grass. discharges were monitored 2 automatic linigrafos precipitation weather station installed on results estimate average 8 per month rainfall 220 mm. initial abstractions 60 mm month, equivalent 24% total evapotranspiration losses correspond stores not observed. experiment makes significant contribution determining volumes forecast trencher compensatory meausure drainage. Keywords: trench, storage, rainwater.
