The invention discloses an LID (low impact development) type rainwater ditch and a design and calculation method for the same, and is applicable to various rainwater drainage ditches such as drainage ditches, farmland drainage ditches and floodwater drainage ditches on two sides of a slope and two sides of a road. The rainwater ditch comprises a ditch, storage dams, overflow ports, a rubble layer, a sandy soil layer, ecological slopes and the like. The sandy soil layer is laid on a bed of the ditch, the rubble layer is laid on the upper side of the sandy soil layer, and the storage dams are longitudinally continuously arranged along the ditch and are separated from one another by a certain distance, so that a series of reservoirs which are continuously distributed are formed along the ditch. The design and calculation method includes designing and calculating layout spacing of the water storage dams and the sizes of the overflow ports. The LID type rainwater ditch and the design and calculation method have the advantages that the LID type rainwater ditch has multiple functions of 'drainage, water storage, infiltration and decontamination', and is incomparable to a hard rainwater ditch only with a drainage function; the LID type rainwater ditch is high in water storage capacity and drainage speed which are deficient in a wetland bed type rainwater ditch; the rainfall flood runoff volume can be obviously reduced, the groundwater recharge can be improved, non-point surface pollutants of rainwater can be reduced, and environments can be beautified.
