资源简介：
Stopbanks are continuous mounds of earth built near rivers to stop water from the river flooding nearby land. Americans call them levees. They may look like grassy banks, but they are actually constructed according to very specific engineering designs. When the river is in flood, they need to be able to contain the floodwaters without collapsing.
