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..<br>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).瓦尔河（Waal River，莱茵河分流汊道）中线在河道公里桩894至911区间的河床高程数据集，数据来源于覆盖瓦尔河通航航道的双周频次多波束测深数据（Multibeam data），测量时段为2011年至2020年。Z_locations.csv存储了各测点（行）在各测量日期（列）对应的河床高程；MXY_locations.csv包含测点地理坐标信息，其中第一列为沿河道中线的距离，第二、第三列为RD新地理参考系（RD new geographic reference system, EPSG:28992）下的X、Y坐标；dates.csv记录了所有河床高程测量的具体日期。QTiel-2009_2020_daymean.csv为2009年1月1日至2020年12月31日期间蒂尔水文站的日平均流量数据，该测站是瓦尔河研究区域内距离最近的流量监测站点。 本数据集可用于分析河床沙波，相关细节详见配套研究论文。分析方法与代码已单独公开（https://doi.org/10.5281/zenodo.5764363）。
