Levelling
Land levelling is a measure used in surface irrigation, such as basin.
It consists of preparing the irrigation plot in a way that no high and/or low spots disturb the uniform distribution of irrigation water on the field.
Purposes for levelling of soil are-
- To find the elevations of given points with respect to a given datum
- To establish points at given elevations or different elevations with respect to the given or assumed datum.
