Coastal_profile P1

The Coastal dynamics, sediment transport, are monitored in two detailed terrain profiles. Profile 1 is a c. 250 m long profile line crossing a curved spit near the old delta (see map in: GeoBasis_Zack_Geomorphology_P1_Coastal_profile.pdf).
The coordinates giving here are from a fix peg along the profile.
The profile has been monitored approximately every second year from 1991-2013, whereafter the frequency of measurements has been reduced to every fifth year.

本数据集针对海岸动力与泥沙输运开展监测，共设置两条精细化地形剖面。剖面1为长约250米的测线，横穿古三角洲附近的弧形沙嘴（详见GeoBasis_Zack_Geomorphology_P1_Coastal_profile.pdf中的附图）。本次提供的坐标取自该剖面沿线的固定测桩。该剖面自1991年至2013年期间约每两年监测一次；2013年之后，监测频率调整为每五年一次。
