泥石流造成建筑物、道路、涵洞等工程设施的破坏。可以使用狭缝坝来控制可能损坏或破坏小流域基础设施（如涵洞）的少量碎片。坝柱的高度和间距以及坝的位置是主要的设计因素。立柱可布置成单排或双排，缝隙间距取决于受保护涵洞的直径。坝的高度是坝所处坡度的函数。缝坝的优点包括设计和安装简单以及相对较低的成本。它们也比其他挡板系统和碎片围栏更坚固。
Debris flows cause the destruction of engineering facilities including buildings, roads, and culverts. A slit dam may be used to control small volumes of debris that can damage or destroy small watershed infrastructure, such as culverts. The height and spacing of the dam posts and the location of the dam are the primary design factors. The posts may be arranged in single or double rows with the spacing of the slits a function of the culvert diameter being protected. The height of the dam is a function of the slope on which it is placed. The advantages of slit dams include the simplicity of design and installation and the relatively low cost. They are also stronger than other baffle systems and debris fences.
