Water landscape design method enabling flow characteristics of tidal floods rarely happening to reappear scientifically

Abstract

The invention provides a water landscape design method enabling flow characteristics of tidal floods rarely happening to reappear scientifically. Actual measurement terrain, geological data and hydrologic data of a natural river course are collected; the range of model, the number of section boards and adopted materials are determined according to a similarity criterion; a lofting section is selected from an actual measurement topographic map, and a model section board the same as a natural riverbed in form is manufactured; a control wire of the model is determined, a model side wall line is designated, a horizontal control network and a vertical control network are made, a bench mark is set, and the model is installed according to a river course topographic map; actual measurement runoff flow hydrographs and river mouth actual measurement tide tide-level hydrographs of dry season typical days and flood typical days of a natural river hydrometric station are verified; flow rates of corresponding sections of a natural riverbed are verified; erosion and deposition verification is carried out on the actual measurement topographic map of the natural river course and the model before and after channel forming discharge occurs; a water circulation system is established, so that water landscapes designed according to the method have extremely high academic value and added economic value.

Description

technical field [0001] The invention relates to a water landscape design method capable of scientifically reproducing the flow characteristics of rare tidal floods. Background technique [0002] Along with economic development and social progress, the construction of ecologically civilized cities continues to advance. The concept of urban planning and construction that the city is in the water and the city in the forest has been widely used. Landscape construction is the main means of creating the urban outdoor environment. Water is the source of life. Water nourishes the city, giving birth to countless ancient cultural capitals and famous historical cities. Water maintains social progress and human civilization. It is precisely because of the inherent hydrophilicity of human beings that in urban landscape design, It is always closely connected with rivers, lakes and seas. At present, water landscape design is in the ascendant all over the country. A series of landscape cons...

AI Technical Summary

Problems solved by technology

[0004] At present, urban landscape design is only ornamental and recreational, and there is no water landscape design technology that can scientifically reproduce the flow properties of natural rivers in the sense of hydraulics. It is impossible to solve various major wading technical problems under complex hydraulic conditions through water landscape design.
