Karst landscapes, from Normandy and the Grands Causses to Guilin, Yucatán, Florida, Madagascar, and the Nullarbor, are major freshwater reservoirs that are hard to predict, vulnerable to turbidity, and essential to drinking-water management

Dry valleys can kill: parched soils turn rain into sudden, destructive flash floods. Pakistan, the Sahel/Horn countries, and several Gulf and Middle Eastern states top the list of places where dry-valley floods have repeatedly caused the most human harm.

Yemen has no permanent rivers, yet its dry valleys, wadis, turn into deadly flash floods during intense rainy seasons, destroying homes, killing dozens, and displacing tens of thousands. This post explains how Yemen’s unique hydrology works, why floods are so destructive in a war‑stricken, climate‑vulnerable country, and what it means for water security and flood risk management.

Denmark’s hydrological challenge is a delicate balancing act: protecting groundwater-dependent drinking water, managing drought and flooding, and adapting to rising coastal and groundwater risks.

We’re pleased to announce the release of BWI service v2.16.00, bringing meaningful improvements to forecast horizon and data transparency.

The Atlantic Multidecadal Oscillation is a slow-moving climate pattern with outsized influence on river systems. By shaping atmospheric circulation, precipitation, and groundwater recharge over decades, AMO can alter river flow regimes, drought persistence, and flood risk across continental basins.
