An analysis is made of the characteristics of the construction, design and process flow of the waterfall engineering of Zhuzhou Cultural Park, with some suggestions on how to handle the problems to be solved in this project.

Drop water is one kind of common channel system structures,it mustexist that the transition from supercritical flow to subcritical flow when water pass through the gap of drop water.

if we could use the drop water to gauge water accurately, it might not only reduce the loss of head caused by gauging facility of irrigation system, but also might save a lot of additional construction costs for gauging water and also reduce the project quantity, so it is one kind of economical and conv.

Discussion on application of square-shaped vertical drop;

Study on timing for navigation safety evaluation to be conducted for waterborne engineering

As a result,this paper recommends the integrated constructed terrace wetland because it can make good use of drop aeration,and the wetland covers less land and needs lower cost on running and managing than wastewater plant.
