Capacity evaluation of hydropower for accommodating wind‐photovoltaic power generation in the dry season

open access: yesIET Renewable Power Generation, 2023
Considering that the benefits of hydropower stations from regulating and consuming new energy are restricted during the dry season due to the inadequate regulation capacity, this paper focuses on the accommodation capacity evaluation of hydropower for ...

Dramatic Decline in Organic Carbon Burial in Big Estuary Driven by Dam Construction: Insights From the Yellow River Estuary

open access: yesEarth's Future, Volume 14, Issue 3, March 2026.
Abstract Estuaries and associated shelf deposits, which bury 70%–90% of global marine organic carbon, making them key sites for marine carbon burial. Variations in total organic carbon (TOC) content and the organic carbon burial rate (OCBR) in these sediments strongly influence carbon sequestration dynamics.

Spatiotemporal Dynamics of Streamflow Drought in the Larger Alpine Region

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Streamflow droughts are spatial phenomena that are generally not restricted to individual rivers or catchments. However, many studies spatially limit their drought analysis, for example focusing on a specific country or catchment only, which makes it difficult to study spatiotemporal drought evolution in detail.
