The geometry of geo tube is very important. For exsample, you need ‘geotube seawall’ to protect shoreline from eronsion, knowing maximun filling height of geo tube is necessary to compelte the project safely and sucessfully, because you don’t want pump to working constantly exceed max height and see it’s possible failian. Another scenes, you are going to dewatering industry processing slurry stored in sediment pond, that will be great if you know geotextile tube can hold sludge volume finally, also geotube width and height.
