Design of a Bioretention System with Water Reuse for Urban Agriculture through a Daily Water Balance

Urban Farm DB summary

Using lysimeter data from a golf course in Spain, researchers designed and validated a sustainable urban agriculture drainage system with water reuse (SUADS-WR) based on a daily water balance, estimating reference evapotranspiration via the Penman-Monteith or Hargreaves-Samani methods. Compared with experimental data, estimated irrigation depths were lower than the water actually supplied, and estimated percolation matched measured field drainage. Implementing SUADS-WR allowed harvested water to cover more than 38% of the crop's annual water demand.
