RAINFALL AND DRAINAGE
Irrigated areas in arid climate zones tend to be oversalted. Due to the high evaporation the saliferous water is guided to the soil surface with the ascending water stream. The salt washed out is deposited onto the soil. This leads to desolation and unfertility. The application of the drainage avoids this reaction as the ascending saliferous water is lead off.
These pipes, composed of suckers (50 – 65 mm) and collectors (80-200 mm) are laid about 0,80-1,20 m beyond the soil with an incline of about 0,25-1,0%.
