Abstract: Based on the interpretation of the generation law of natural water with full combination of terrain conditions, “Naturalistic” waterscapes uses computer technology to help simulate natural forms and ecological processes, in order to generate a natural water landscape system. This article focuses on the key elements of waterscape, building a dynamic relationship between “form-dam height-water quantity”. According to the parameterized design logic, the algorithm is compiled to create a parametric design model by using Grasshopper. With this method, the multi-elements integrated design and dynamic regulation of water quantity, water form, and engineering volume is realized.
