[해외자료] North Korea’s Punggye-ri Nuclear Test Site: Floodwaters Wash Out Bridges and Limit Access to the Test Tunnels

Commercial satellite imagery indicates that the portal area of North Korea’s Punggye-ri Nuclear Test Site incurred minor storm damage after the heavy summer rains, a pattern observed following the monsoon season year after year. Beyond flood-related activity, little else appears to have changed since our last update. Notably, no recent work has been detected either at Tunnel No. 3 (South Portal)...

[학술논문] 북한 황강댐 유출량에 따른 임진강유역 홍수 피해 지역 시뮬레이션

우리나라는 매년 여름철마다 태풍과 집중호우가 함께 발생하는 홍수로 인해 인명 및 재산피해가 발생한다. 특히 임진강 유역은 급경사와 좁은 하도인 상류부와, 낮은 평지인 하류부로 되어 있어 홍수에 취약한 지형을 가지고 있다. 게다가 북한 지역의 임진강 상류에 위치한 대형 댐인 황강댐에서 여름철 마다 무단방류로 인하여 피해가 발생하였다. 이런 홍수 피해를 방지하기 위해 우리나라에서는 2010년 군남홍수조절지를 건설하여 홍수피해를 방지하고 있다. 하지만 홍수조절지의 건설 이후에도 홍수조절능력이 황강댐의 최대 저수량의 20%밖에 미치지 못한다. 이에 이 연구에서는 경기북부지역의 집중호우시 발생할 수 있는 홍수 피해 위험지역을 산정하기 위하여 LAHARZ_py 프로그램을 이용하여 피해예상지역을 산출하였다. 그 결과 군남홍수조절지의

Also, based on the estimated BAU of North Korean forests, the anticipated deforested area, which fits the REDD+ project condition, was sorted out to be 971Kha. Thus in total, the possible area of the REDD+ project in North Korea is 2,461Kha. With the same...

The Yeongdeok Fault dips eastward with an angle of 65° at most outcrops and shows its fault cores and damage zones of 2~15 m and of up to 180 m wide, respectively. The fault cores derived from several different wall rocks, such as granites and sedimentary and volcanic rocks, show different deformation patterns...
