Every year on 21 June, the global scientific community celebrates World Hydrology Day to highlight the importance of water sciences play in sustainable resource management and natural hazard mitigation. Historically, human efforts to protect and manage freshwater have suffered from a blind spot. While we can easily measure a river’s flow at a specific gauging station, predicting how an untou ...[Read More]

Tidal flats, the muddy reaches of estuaries unveiled at low tide, support rich ecosystems and fisheries worldwide. But these habitats are under threat from climate change, as sea level rise overwhelms the landscape and heavy rainfall scours away the sediment – impacts that scientists are only just beginning to explore. In an effort to understand how shellfisheries are affected by climate change, a ...[Read More]
