Frequency analysis of extreme rainfall and flood events are used to determine design rainfalls floods which needed hydraulic structures such as dams, spillways culverts. Standard methods for frequency based on the assumption a stationary climate. However, this in is being challenged with growing evidence climate change. As consequence changing climate, magnitude reported have increased parts So...

In South Korea, flood damage mainly occurs around rivers; thus, it is necessary to determine the optimal design frequency for river basins prevent damage. However, there are not enough studies showing effect of climate change on hydrologic frequency. Therefore, estimate according future scenarios, this study examined urban flooding area and extreme rainfall that can in future. After estimating ...

Background: Previous studies have been reported on the toxicity of Microcystin-LR, which is produced by cyanobacterial growth in fish, such as Heteropneustes fossilis (H. fossilis). However, no studies have been conducted on the effects of Microcystin-LR on the prolactin cells of H. fossilis. Methods: H. fossilis fish were intraperitoneally injected with Microcystin-LR (2.5μg/25g) and sacrif...

Shallow landslides triggered by heavy rainfalls have caused casualties and economic losses to domestic infrastructures industries worldwide. Rainfall mainly reduces the soil matric suction shear resistance, resulting in shallow landslides. Vegetation is an eco-friendly cost-effective method for stabilizing slopes prone This research aims investigate hydrological mechanical effects of vegetation...
