When Droughts Dry Up Power: The Climate-Hydropower dilemma

When Droughts Dry Up Power: The Climate-Hydropower dilemma

When we think of hydropower, its environmental impacts usually comes to mind: the dams that disrupt ecosystems, the water bodies that shift, the surface evaporation that increases, and the greenhouse gases that escape from reservoirs1. Hydropower, for all its clean energy potential, is not without its environmental baggage, whether on local water resources or the global surface water storage. But ...[Read More]

Shaping the HS-programme of EGU25: Session Review, Merging, and Co-Organization Updates

Shaping the HS-programme of  EGU25: Session Review, Merging, and Co-Organization Updates

September has arrived. The Hydrological Sciences (HS) community has been very active, as usual, submitting 152 sessions during the open session call, which is more than 10% of all sessions that are proposed for the entire EGU (overall 1,273 sessions were submitted, slightly more than at EGU24). This is amazing and I would like to thank all the conveners for their excellent ideas and nice work so f ...[Read More]

Hortonian overland flow: when theory becomes reality

Hortonian overland flow: when theory becomes reality

Hortonian overland flow – if you have ever followed a hydrology class, you have certainly come across this jargon:  this is the name of a hydrological process – when rainfall flows off at the terrain surface because the rainfall intensity is so high that not all the water can infiltrate into the soil (rainfall intensity is higher than infiltration capacity). Almost every hydrological m ...[Read More]
