Changing weather patterns and hundreds of dams blocking sediment flows are putting two-thirds of California's beaches at risk of disappearing by the end of the century, the US Geological Survey's Patrick Barnard predicts in a study. The danger to seaside structures is already evident.

Jet erosion tests used to evaluate two fluvial erosion models -- the empirical excess shear stress model and the mechanistic Wilson model -- found that erodibility parameters varied by two to five and one to two orders of magnitude in Oklahoma's Illinois River watershed and Fort Cobb Reservoir watershed. However, there was less variation in predicted retreat by a process-based model compared with the input erodibility parameters.

A new model incorporating sedimentary control of ice sheet flow is being floated to explain the slowing of the land-terminating margin of the Greenland ice sheet. An initial observational test of this model documents transient modifications of basal sediment strengths by rapid subglacial drainages of supraglacial lakes as the primary current control on summer ice sheet flow.

Following up on more than a year of threats, New York Gov. Andrew Cuomo's administration is suing the Environmental Protection Agency to prevent dredged sediments from being dumped in Long Island Sound. The dredging plan is supported by Rhode Island and Connecticut, with most of the dredging occurring in the latter's waters.

A study of increased sedimentation in lakes around the world focused on the middle and lower reaches of China's Yangtze River basin. Among other things, researchers found that certain types of land use, especially reclamation for croplands and rapid urbanization, boosted sedimentation rates substantially.
