Aeolian dunes are typical sand dunes which are maintained and developed by interactions of earth surface, wind and vegetation. Developing a model which can predict the changing phenomena of these sand dunes is vital in enhancing the efficiency of understanding and management of terrains such as land...

| 사구란 무엇인가? | 사구는 바람으로 운반된 모래가 쌓여서 만들어진 언덕이며, 건조한 지역에서 발생하는 풍성사구(Aeoline Dunes)는 지표 기복, 바람과 식생 간의 상호 작용에 의해 유지∙발달되는대표적 사구이다(Baas and Nield, 2007; Wiggs et al., 2012;Bishop et al. | |
| 바람 침식 모델만을 이용하여 사구 장기 거동성을 예측하는데 제한이 생기는 이유는 무엇인가? | , 2013). 풍성사구의 변화는 모래의 이동이 가능한 일정 이상의 바람에 의해 사구의 둔덕을 형성하며, 형성된 둔덕은 다시 바람의 흐름에 영향을 받는다. 바람이 직접적으로 부딪치는 사면에서는 풍속이 빨라지고 둔덕의 뒤에 형성되는 바람그늘에서는 풍속이 감소한다(Wiggs, 2001). 이러한 바람만을 고려한 바람 침식 모델은 복잡성을 단순화하여 사구의 형성과정을 이해하는데 도움이 되었지만, 실제 지형에서는 바람뿐만이 아니라 사구에 존재하는 식생이 사구 장기 거동에 큰 영향을 가지고 있다. 따라서, 바람 침식 모델만을 이용하여 사구 장기 거동성을 예측하는데 한계가 있어 실제 지형에 적용하기에는 어렵다(Thomas et al. | |
