Input dune analysis for: Rive dune dynamics during low flow

Bed elevation of the centre line of the Waal River (distributary of the Rhine River) between river kilometre points 894 and 911, derived from biweekly Multibeam data covering the fairway of the Waal river. The measurements cover the period from 2011 untill 2020. Z_locations.csv gives the elevation of each point (rows) at each date (columns), MXY_locations.csv contaions to the geographical locations where the first column gives the distance along the line and the second and third columns give X Y coordinates in the RD new geographic reference system (EPSG:28992). dates.csv contains the dates the bed elevations were measured. QTiel-2009_2020_daymean.csv are the daily mean discharges at measurement station Tiel for the period from 1 Jan 2009 up to 31 Dec 2020, this is the discharge gauge closest to the study area within the Waal River.. These data are used to analyse the dunes on the river bed as described in the companion paper. The analysis method is described in the companion paper and the analysis scripts are published separately (https://doi.org/10.5281/zenodo.5764363).

本数据集为莱茵河（Rhine River）入海分流汊道瓦尔河（Waal River）河道公里桩号894至911段中心线的河床高程数据，数据源自覆盖该瓦尔河航道的双周一次多波束（Multibeam）测深数据，观测时段为2011年至2020年。
Z_locations.csv中各行对应单个测点，各列对应单个观测日期，存储各测点在对应日期的河床高程；MXY_locations.csv包含测点的地理坐标信息，其中第一列为沿河道中心线的里程，第二、第三列为RD新地理参考系（EPSG:28992）下的X、Y坐标；dates.csv收录所有河床高程观测的日期；QTiel-2009_2020_daymean.csv为2009年1月1日至2020年12月31日期间蒂尔（Tiel）测量站的日平均流量数据，该流量监测站是本次研究区域内瓦尔河段最邻近的官方监测站点。
本数据集用于配套论文中所述的河床沙波分析，分析方法已在配套论文中详述，配套分析脚本已单独发布（https://doi.org/10.5281/zenodo.5764363）。
