Third paper from Qiuyu Zhu's PhD now out. Qiuyu coupled Spatially Distributed TOPMODEL to a hydrodynamic model to see how different NFM techniques interact. This allows us to study flood effects at larger catchment scales. Free access here: onlinelibrary.wiley.com/doi/10.1111/...

A Coupled Hydrological‐Hydrodynamic Modelling Approach for Assessing the Impacts of Multiple Natural Flood Management Interventions on Downstream Flooding

While natural flood management (NFM) as a flood mitigation strategy is becoming widely used, there remains a lack of evidence regarding the effectiveness of different NFM scenarios under high flow ev...

Great work by our PhD student Yu Liu who has shown in AGU Advances that recent forest loss in the Brazilian Amazon causes substantial reductions in dry season precipitation. Open access here: agupubs.onlinelibrary.wiley.com/doi/full/10....

Recent Forest Loss in the Brazilian Amazon Causes Substantial Reductions in Dry Season Precipitation

Recent forest loss (3.2%) in the Brazilian Amazon causes a mean 5.4% reduction in dry season precipitation 76.9% of reduced precipitation is due to decreased nonlocal water vapor, not local evapo...

Wetland fragmentation is strongly associated with high population densities. African wetlands store an estimated 54 ± 11 Gt of carbon (surpassing Europe’s 12–31 Gt). If drained, they could release 260 MtC / yr, nearly ten times the carbon sequestration of pristine wetlands (27 MtC /yr).
