Geomorphology of the Coastal Sand Dune Fields and Their Association with the Palaeolandscape Evolution of Akrotiri Peninsula, Lemesos, Cyprus

Abstract

Two well-developed late Pleistocene dune fields have been identified on the western and eastern side of Akrotiri promontory (Lemesos, Cyprus). The dune fields extend immediately from the low level of their source beaches onto higher ground (>48 m amsl). Geomorphic observations supported by OSL dating and sedimentological data provided evidence of the dune development and for the palaeogeographic reconstruction of the area. Relative sea level changes and wave action during the upper Pleistocene and Holocene played an important role into the development of the palaeolandscape and affected the formation of the dunes. From the collected data the development of the western dune field started at 56.2 ± 5.5 ka when the relative sea level was at approximately −60 m and contributed to the development of the western tombolo of the area whereas the eastern dune field developed in the late Holocene, after the formation of the eastern spit that resulted in the formation of the Akrotiri Salt lake.

The Study of Distribution for the Flora of Alien Species and Ecosystem Disturbing Species on Coastal Sand Dune in Chungcheong to Jeolla Region, South Korea

“…해 안사구는 해빈과 간석지의 모래바람에 의하여 형성된 언덕이 다 (Choi, 2019a). 해안사구는 해빈과 간석지로부터 바람에 의해 유입된 모래를 저장하였다가 폭풍이나 해일과 같은 자 연재해가 발생하였을 때 유실된 모래를 해빈과 간석지로 되 돌려주는 모래의 저장고이자 천연 해안제방 역할을 한다 (Polidorou and Evelpidou, 2021;Sigren et al, 2014). 구릉 형태의 해안사구는 지하수면을 높여 배후지역에 생활•농업용 수로 사용할 수 있는 담수를 공급하고 바닷물과의 밀도차에 의해 바닷물이 육지로 침입하는 것을 방지하여 육상의 담수 생태계를 보호한다 (Dang et al, 2021).…”

Deciphering Depositional Environment of Playa Lakes Using Grain Size Parameters in the Arid and Semi-Arid Region of Rajasthan, India

“…The grain size distribution and sample statistics were computed based on the method explained by Folk and Ward [45,46], which uses the following relations (Equation ( 1) to ( 4)) for the computation of mean (Mz), mode, sorting (σ I ), skewness (Sk I ), and kurtosis (K G ), and the description is given in Table 1. Several other authors also used a similar relationship [47][48][49] to calculate the mean, mode, sorting, skewness, and kurtosis.…”
