Input dune analysis for: Rive dune dynamics during low flow

dates.csv
	Date of measuring each location of the Waal River (Netherlands) along the axis of the fairway
	column names: refer to the dates between which the measurements along the whole line were done
	index column: gives the index of the point along the axis of the fairway, same as index in MXY_locations and Z_locations
	column names and the index column link the dates to the MXY locations and bed elevation
	Dates given in YYYY-MM-DD
	
MXY_locations.csv
	Locations of each point along axis of the fairway of the Waal River (Netherlands), rkm 894-910
	column names refer to 
	M: distance along the axis in [m] 
	X: x-coordinate in [m] 
	Y: y-coordinate in [m]
	index column: gives the index of the point along the axis of the fairway
	Index column links the locations to the bed elevation and dates
	XY locations given in RDNew reference system (crs code: EPSG:28992)

Z_locations.csv
	Bed elevation data of the Waal River (Netherlands) along the axis of the fairway, rkm 894-910 based on MBES data.
	column names refer to the dates between which the measurements were done, equal to the column names in dates.csv
	index column gives the index of the point along the axis of the fairway, equal to the index in MXY_locations.csv
	column names and the index column link the bed elevation to the MXY locations and dates
	Elevation data reference: m+NAP (NL: Nieuw Amsterdams Peil, EN: Amsterdam Ordnance Datum)
