Contour ditch irrigation is also known as wild flooding. It consists of a series of ditches spaced 25 to 100 m apart. There is a slight slope along these ditches and usually, the downslope bank is lower so that the water, when checked, is not restrained from flowing into the field along the entire ditch. Sometimes, water release into the field is accomplished by making cuts through the down-slope bank or using siphons. Theoretically, in contour ditch irrigation the water moves down the slope as a uniform sheet. Successive ditches located down the slope pick up the surface runoff and redistribute it to lower portions of the field.  4, record 1, English, - contour%20ditch%20irrigation

Irrigation par rigoles de niveau. Cette méthode consiste à inonder abondamment le sol à partir de fossés disposés à peu près selon la courbe de niveau et espacés de 75 à 300 pi (23 à 90 m) l'un de l'autre. Comme cette méthode exige beaucoup de main-d'œuvre pour n'assurer qu'une faible efficacité, elle ne devrait être utilisée qu'en attendant de terminer le nivellement du terrain pour adopter une méthode plus efficace.  3, record 1, French, - irrigation%20par%20rigoles%20de%20niveau

L'irrigation par rigoles de niveau ou par rases : les rigoles de niveau s'utilisent en régions de montagnes sur des terrains à forte pente (jusqu'à 25 %) ou accidentés. Les rases constituent une variante pour les terrains à faible pente. On doit donner de la pente aux rigoles qui ne sont plus parallèles mais légèrement obliques par rapport aux courbes de niveau.  4, record 1, French, - irrigation%20par%20rigoles%20de%20niveau

Method of irrigation which consists of spilling water at frequent intervals from a grade ditch constructed along the high edge of a sloping field. The water is allowed to flow freely down the slope, irrigating the soils the water moves across. Interceptor ditches are placed at intervals down the slopes to collect the water. Used primarily for irrigating low-income crops on steep lands where uniformity of water distribution is not a major consideration.  2, record 3, English, - wild%20flooding
