Infrastructure projects like roads and dams destabilize slopes and compound the effects of glacial floods and avalanches, scientists say.
Increased seawater exposure from flooding and storms is altering how coastal forests cycle methane, leading to more greenhouse gas accumulation in tree stems and soil.
Natural hazard impacts and resources allocated for risk reduction and disaster recovery are often inequitably distributed. New research is developing and applying methods to measure these inequities.
Scientists call for joint efforts to combine real-time global rainfall data with high-resolution local hydrology to better forecast floods.
Researchers mined maps of natural hazards and land use to show that nearly 60% of structures are built in regions at high risk of earthquakes, wildfires, floods, hurricanes, and/or tornadoes.
Many of the house-sized boulders that litter Himalayan river channels were transported thousands of years ago by glacial lake outburst floods, new observations suggest.
In areas of low or no flood monitoring, archival coverage of historical flooding can help scientists make better risk predictions.
Scientists are working to improve the forecasting of heavy rains in Panama following several events over the past decade that caused substantial flooding and damage.
Nationwide, civil engineers consider precipitation values from NOAA to design their structures. But those values are missing another contributor to flood risk: snowmelt.
Weather forecasting can greatly improve benefits of rainwater harvesting.
