畦灌（borderirrigation）是指在田间筑起田埂，将田块分割成许多狭长地块――畦田，水从输水沟或直接从毛渠放入畦中，畦中水流以薄层水流向前移动，边流边渗，润湿土层，这种灌水方法称为畦灌。
But border irrigation and furrow irrigation can have disadvantages, such as possible water wastage and lower irrigation efficiency. So research is justified into the theory of border and furrow irrigation, to improve and perfect irrigation design.
