Abstract

A method for digital restoration of historic morphology of a river, comprising: selecting, on the basis of the selection of a river segment where the development of an alluvial stream and terraces is complete, a representative cross section of a river segment planned to be recovered; obtaining a sediment core sample by drilling; layering sediments according to physical properties thereof; recording three-dimensional space coordinates of each layer, then performing age determination on each sediment layer, and finally connecting the three-dimensional space coordinates of the sediment layers of equal age in different sediment cores on the same section in general drawing software by using lines, wherein the obtained section morphology is river section morphology under the age; and linking the coordinates of all ages in sequence, that is, morphology recovery of the entire section in all history ages is completed, and historic morphology restoration of the entire river segment can be completed after multiple sections are recovered. By means of cross utilization of a geology age measuring technology and a river dynamics section molding principle, the method can be applied to most alluvial river historic morphology restoration, and has important practical value for the study of a river landform evolution process.

Description

technical field

[0001] The invention relates to the field of river geomorphology, in particular to a digital restoration method for river historical forms. Background technique

[0002] The historical evolution of rivers is a key issue in understanding the dynamic process of river geomorphology, and it is also the basis for mastering the law of large-scale evolution of rivers. Different from the analysis of the recent evolution of rivers, there are relatively sufficient measured data, and the historical evolution of rivers usually lacks reliable information and data. According to the "Code for Investigation and Investigation of River Channel Evolution (SL383-2007)", for a long time, the historical evolution data of rivers have been obtained mainly from river historical textual research, regional structural background investigation, paleochannel investigation and crevasse alluvial fan investigation. Textual research relies on historical documents; regional tectonic backgroun...
