Schematized model of the lower Rhine River (2000-2100) - input and results

Input files and model results for a schematized morphodynamic model of channel response of the lower Rhine River to climate change and human intervention. <br>These model files are related to the manuscript <em>Centennial Channel Response to Climate Change in an Engineered River</em>. <br>Input files (for modeling tool SOBEK-RE) include:- cross-section data, with main channel and floodplain width at each cross section (cross-sections.txt)- initial mean bed elevation (bedlevel_ini.txt)- initial bed surface and substrate composition per fraction (gs_ini.txt)- boundary conditions for the reference case and (climate) scenarios: upstream water discharge, upstream sediment flux, downstream water level (#scenario#_QKoln.txt, #scenario#_BaseLevel.txt, #scenario#_SedFlux.txt)<br>Model results (ModelRuns_2050-2100.xlsx) include for the reference case and climate scenarios: - Main channel bed elevation at 2050 and 2100 - Geometric mean grain size at 2050 and 2100 <br>In addition, the field data collected by Rijkswaterstaat on bed surface grain size in the Dutch Rhine in 2020 is also included (grainsize_field_DutchRhine.xlsx). These data has been used as information to derive the model input grain size fraction content.<br>

本数据集涵盖下莱茵河河道响应气候变化与人类干预的概化地貌动力学模型（schematized morphodynamic model）的输入文件与模型结果。
上述模型文件与学术论文《工程化河流百年尺度河道响应气候变化》（*Centennial Channel Response to Climate Change in an Engineered River*）相关。
针对建模工具SOBEK-RE的输入文件包括：
- 断面数据：包含各断面的主河道与漫滩宽度（cross-sections.txt）
- 初始床面平均高程（bedlevel_ini.txt）
- 初始床面与底床沉积物的组分构成（gs_ini.txt）
- 基准情景与（气候）情景的边界条件：上游来水流量、上游输沙率、下游水位，对应文件格式为#scenario#_QKoln.txt、#scenario#_BaseLevel.txt、#scenario#_SedFlux.txt
模型结果存储于文件ModelRuns_2050-2100.xlsx中，涵盖基准情景与气候情景下的内容：
- 2050年与2100年的主河道床面高程
- 2050年与2100年的几何平均粒径
此外，数据集还包含荷兰公共工程与水管理总司（Rijkswaterstaat）于2020年在荷兰境内莱茵河河段采集的床面粒径野外实测数据（grainsize_field_DutchRhine.xlsx），该数据曾用于推导模型输入所需的沉积物组分占比。
