The Need for Drainage/ Drainage Design
The Evolution of Sportsturf Drainage
Agricultural drainage
objectives
increase number of times a year cultivation + grazing can be carried out
without damage to soil
removing excess water from the soil profile
more favourable physical environment
how
removing water faster than it would naturally
returning soil to its field-drained state after rainfall
adverse effects of waterlogging removed
sportsturf drainage
sports events take place irrespective of weather
priority is the rapid transport of water through the soil to the pipe drains
Benefits of drainage
removal of excess moisture
lowering of the water table
improves
quality
firmness
durability of turf
particularly winter games
improving traction
Quicker drying of the soil
extending possible playing time
Reduction of erosion
preventing surface run-off
Better air movement in the soil
Increased root development
Improved drought resistance
longer growing season
Improved results from bacterial breakdown
Drainage Problems
Watertable
Impermeable subsoi
Springs
Old drains
A water-table is the boundary within the soil profile between the unsaturated soil overlying saturated soil
