Land drainage is principally accustomed to reduce waterlogging in fields and gardens, but it surely might also dessiccate specific ground varieties in prolonged dry spells, so think twice just before setting up.

From soil variety to outfall availability, there are plenty of complex elements to take into consideration when developing a new drainage process.

Nonetheless, it may be stated which the opportunity for subsurface drainage to lessen peak circulation charges within the field scale doesn’t guidance the Idea that subsurface drainage exacerbates flooding at greater scales.

How a lot more infiltration could manifest around the drained as opposed to the undrained soil? This relies on numerous variables, but the quantity will probably be increased when:
