In areas of heavy rainfall or low soil percolation, it is necessary to employ surface drainage systems to get rid of surplus surface water from the land. Commonly used surface drainage systems include shallow ditches, open channels, grassed waterways and sloped banks. These drainage systems drain away surface water quickly and efficiently, but do not make much of a difference to groundwater. If there are land drainage problems due to groundwater, they will need other solutions. Surface drainage needs to be carefully planned by taking into account the land's topography, the amount of rainfall received, and the type of soil. In some cases, shallow ditches following the land contour may be enough, in others the ditches may need to be deeper or the land may need to be graded or sloped to facilitate soil drainage.

Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging anaerobic conditions that harm root growth , but many soils need artificial drainage to improve production or to manage water supplies.
