1. Comparison of Beach Profile Change and Migration of Vegetation Belts at Sand Barrier in Nakdong River Estuary, Korea.

Author

Chang-ill Yoo and Han-sam Yoon

Abstract

The article focuses on a study which described characteristic of beach profile change and movement of vegetation belts at the sand barrier in the Nakdong river estuary in Korea with a focus on geomorphological evolution and mobility of sand barriers in the view of coastal engineering. A survey of the beach profile change between 2005 and 2007 confirmed the deposit of sediments on the swash zone and the front of dune.

Abstract

Estimates of dynamics of two Altai glaciers Tomich (Katun Ridge) and Vodopadny (North Chuisky Ridge) for the whole period of instrumental observations are shown in the paper. Data on changes of the glaciers’ areas and volumes were obtained from the topographic maps, satellite images and author’s field researches performed in 2009–2011. During the period of observations (1952–2012), the glacier areas decreased by 19–25%, and the volumes by 34–45%, and the maximum loss of ice took place since the mid-1990s up to present time. The annual rate of the ice loss has been linked to the average summer air temperature over the glacier area of Altai.
