• Running water in the land surfaces is widely distributed, it is in the flow process, constantly changing the surfaces morphology, molded into a variety of running water landform types, running water to wet areas of the most generally active.
• The instrument is made of high-quality synthetic resin, which is firm and not deformed, and the position, form and structure of each part are correct, and the coloring is distinct.
• Expressed as nudging and suspension, nudging is the flowing water makes the sand and gravel sliding along the bottom surfaces, rolling and leaping. Such as flash floods.
• Erosion of Flowing Water, Expressed as undercutting and side erosion. Under erosion refers to the flowing water and the sand and gravel it carries, deepening the erosion of the valley. Side erosion is flowing water on both sides of the valley erosion, the result of the bank slope back, the valley widening.
• This instrument is suitable for primary and secondary school natural geography teaching, teaching the surfaces of the earth after running water erosion, handling, accumulation of landforms formed by the visual aids.
