The spatiotemporal shoreline dynamics of a delta under natural and anthropogenic conditions from 1950 to 2018: A dramatic case from the Eastern Mediterranean

Coastal regions are threatened by natural processes, such as erosion driven by storm surges and the effect of jetties, as well as by human behavior. The coastline of the Yellow River Delta (YRD) was monitored using the general high-tide line method, which combines Remote sensing (RS) and geographic information system (GIS) technology, using multi-spectral scanner (MSS), thematic mapper (TM), and enhanced thematic mapper plus (ETM+) images of the YRD from 1976 to 2014 as a data source. The results demonstrated that the shape and length of the YRD coastline has changed dramatically since 1976. The course of the Diaokouhe channel has resulted in mainly inland erosion in the north, and is primarily marine erosion; therefore, it was termed an erosion-type estuary. However, the coastline of the Qingshuigou course has moved seaward, demonstrating an accretion stage, and was therefore termed an accretion-type estuary. The coastline advanced forward before 1997 and shrank after 2003 in the southern part of the river mouth, which was due to the shift in the river mouth in 1996. It has continually extended outward in the northern part of the river mouth from 2003 onward. The coastline in the southern part of the river mouth has moved randomly, with the occurrence of both erosion and sedimentation caused by land reclamation and sea wave intrusion. In most cases, the coastline has extended offshore, especially in the northern part of the river mouth. The YRD coastline has changed frequently and rapidly from 1992 to 2014. The river mouth channel, river water and sediments, and precipitation were the major factors affecting the YRD. The YRD coastline was mainly in an accretion stage during flow periods. The erosion rate decreased and tended to be stable during a dry period. The coastline was basically stable when dry periods occurred over a long period. The location of Yellow River ports and sea erosion were the main factors driving coastline changes. The coastline was mainly influenced by the flow path of the Yellow River, with recent human activity also becoming a factor.

Evolution of Yellow River Delta Coastline Based on Remote Sensing from 1976 to 2014, China

The development of tourism determines the cultural landscape transformation, spatial development of coastal localities, scale of recreational architecture and other forms of development related to tourism services. The article presents research aiming to analyze tourism development in the context of its impact on the cultural landscape of Polish coastal localities, taking into account the specificity of post-communist countries and supra-regional tendencies. The main objective of this study was to analyze the development of tourism in the context of its impact on the cultural landscape seaside towns and to identify, on the basis of the changes, the nature of tourism and forms of recreation in particular stages of the shaping of elements in coastal locality spaces and recreational architecture. The research was based on historical-interpretation studies, field studies of selected coastal localities, including urban-planning inventories, landscape, and functional and spatial analyses. The research carried out resulted in the identification of the stages of the cultural landscape transformation of coastal localities and indication of characteristic features of architecture and landscape. The journey along the coastline is a temporal journey through the changing nature of buildings, allowing observation of the stage-by-stage nature of investment processes in response to the changing needs of tourists.
