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.本监测数据集针对两处高精度地形剖面开展了海岸动力（Coastal dynamics）与泥沙输运（sediment transport）的监测工作。剖面1为一条长约250米的剖面线，横穿老三角洲附近的弧形沙嘴（curved spit），相关地图详见GeoBasis_Zack_Geomorphology_P1_Coastal_profile.pdf文件。本次提供的坐标取自该剖面沿线的一处固定测桩。该剖面在1991年至2013年间约每两年开展一次监测，2013年之后监测频率调整为每五年一次。
