改进湿周法 improved wetted perimeter method
Shortcoming that ’inflection’ point in wet perimeter method always determined subjectively by eye from a graph is analyzed. The subjectivity is overcome by defining the break in shape using mathematical techniques that was put forward by Gippel.
由于河道湿周法在确定突变点中存在主观性的缺陷，而最大曲率法可以客观的确定河流生态环境需水，避免了主观性。
