ABSTRACT
Drainage planning involves the preparation of a plan for the solution of a drainage problem. The plan will generally consist of a number of measures to be taken and/or works to be constructed. In some cases, the best solution to a drainage problem may well be a change in land use or in farm practices, making the agricultural use of the land less susceptible to excess water. In most cases, however, the core of a drainage plan consists of the construction of some new drainage works. The detailing of such works, being mostly in the domain of engineering, is commonly referred to as design.
