Demountable test bench for trickle irrigation laterals

, : Demountable test bench for trickle irrigation laterals. Rivista di Ingegneria Agraria 25(4): 230-241

A bench to test the hydraulic and functional performance of trickle irrigation laterals was designed and constructed in the National Laboratory of Irrigation, Italy. The bench can test 200-m long laterals, measuring the pressure at the inlet and at 25-m intervals along the lateral, and the inlet and discharge flow rates. The equipment is 25 m long and comprises 8 wire netting paths placed side by side, supporting the lateral.
