This study analyzed groundwater level changes in a monitoring well located in Korea’s Yangsan fault zone, induced by local (Gyeongju and Pohang) earthquakes in Korea and offshore earthquakes around the world. Among offshore earthquakes, the MW 7.3 Honshu earthquake changed raw groundwater level of a maximum of 10.3 cm. The groundwater level data were analyzed by using the Hilbert-Huang transform (HHT),...
The construction of river barrages has led to an increase in groundwater (GW) levels (WL_G) near the upstream regions of these barrages, particularly in the wet season. Statistical approaches were applied in this study to examine the relationships between WL_G and river water (RW) level (WL_R), and electrical conductivity of groundwater (EC_G) and electrical conductivity of river water (EC_R) in the...
