Abstract. The co-occurrence of droughts and heatwaves can have significant impacts on many socioeconomic environmental systems. Groundwater has the potential to moderate impact by moistening soil enabling vegetation maintain higher evaporation, thereby cooling canopy. We use Community Atmosphere Biosphere Land Exchange (CABLE) land surface model, coupled a groundwater scheme, examine how influe...

Contemporary understanding of the impacts climate change on global drought characteristics (e.g., intensities, extents) is still limited and not well understood. This knowledge critical because projected changes in are expected to impact future water availability as influence decisions how resources allocated. The main aim this study improve (extents duration) Anthropocene where rapid environme...

Meteorological droughts like those in summer 2003 or spring 2011 in Europe are expected to become more frequent in the future. Although the spatial extent of these drought events was large, not all regions were affected in the same way. Many catchments reacted strongly to the meteorological droughts showing low levels of streamflow and groundwater, while others hardly reacted. Also, the extent ...

Since weather factors such as precipitation and temperature etc. show repeated patterns every year, it can be said that future changes predicted by analyzing past data. Therefore, when a drought occurs, the groundwater level is also lowered, so seen change in represent drought. Like precipitation, have high correlation with drought, many researchers use SGI (standardized index) to which SPI met...

Groundwater droughts are one of the natural disasters that raise serious water issues for humans, and increasing in frequency due to global climate change. In order identify groundwater droughts, we recorded level fluctuations upstream at Changnyeong-Haman River barrage from May 2012 October 2020, based on characteristics Nakdong stages. Next, grouped levels by K-means clustering, converted ker...
