简介：为了加速暴露的山崩区域，为土壤的hydroseeding和水保存的重新植被，广泛地作为经济地可行的方法之一被使用了。然而，不同hydroseeding材料的效果持续时间是不同的，明确的表达密度在生长和addictives可以渗出的植物上有某个效果。这份报纸论述土壤侵蚀的实验室实验，渗出由使用有斜坡，降雨紧张和药密度的不同条件的一个降雨模拟器的水质量和土壤坚硬。结果证明土壤侵蚀显著地减少了，建议由通风和不透水的树脂的好抵抗侵蚀的效果。渗出的水的重要变化都没在测试期间被观察，它显示在gelling以后，通风和不透水的树脂是不大可能的释放化学物质。高树脂密度将象高费用一样导致差的可使用性，这被发现；后来由于雨点断裂的mudstone击碎的不利愿望原因是普通的玷污表面。在在植物植被上喷洒和它的效果以后的weatherability需要仍然推进调查。
