Nine Reasons Why Extreme Floods may be Worse Than Expected

by Jim Hall 1 August 202225 July 2022

The implications of nature not conforming to statistical assumptions can be devastating; researchers describe why extreme floods may be bigger than we assume.

AI Algorithm Provides More Accurate Forecasts of Water Use

by Jim Hall 29 July 202225 July 2022

The new graph convolutional recurrent neural network (GCRNN) will enable water utilities to forecast water use, even if some sensors fail.

Missouri River Floodplain Expansion, Services, and Resiliency

by Aaron Sidder 28 July 202228 July 2022

Benefits might accrue for both wildlife and climate resiliency if more floodplains along the lower Missouri River were allowed to flood.

Algorithm Detects Thousands of Missing Levees from U.S. Database

by Rachel Fritts 17 June 202229 June 2022

An existing levee database accounts for just one fifth of the country’s actual total levee count, limiting the study of how these embankments affect riparian ecosystem health in the United States.

Logjams May Be Transient but Their Effect is Long Lasting

by Patricia Saco 20 May 202216 May 2022

Even though natural logjams in rivers continuously change and maybe short-lived, their effects in terms of geomorphic diversity and habitat can be surprisingly long-lasting.

Why is Permafrost Groundwater Surfacing?

by Victor Bense 21 April 202214 April 2022

Hydrogeological properties of degrading permafrost come to fruition with a new 3-D modeling study that highlights the increasing role of groundwater in the water cycle of high-latitude areas.

Trees Wearing Accelerometers Help Track Snowstorms

by Rebecca Dzombak 15 April 202215 April 2022

This device allows scientists to measure how much snow is trapped in canopies and predict changes to snowpack—a critical factor in annual water availability.

Hydrologists Should Reconsider How They Calibrate Their Models

by Marc F. P. Bierkens 15 April 202214 April 2022

A new study suggests that the commonly used split sample approach in hydrology, where time series are divided into a part for model calibration and a part for model validation, should be abandoned.

A New Index to Assess Multiple-Reservoir Effects on Peak Floods

by Georgia Destouni 11 April 202220 May 2022

A simple, yet quantitative, index is demonstrated to quantify reductions in the peak flood resulting from multiple reservoirs, arranged in series along the same river reach.
