Hurricane Harvey flood-inundation map of the West Fork San Jacinto River
July 9, 2018

Nineteen inundation maps and detailed flood information from Hurricane Harvey are now available from the U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency. Hurricane Harvey was the most significant rainfall event in U.S. history, both in scope and peak rainfall amounts, since records began in the 1880s.

Evaluating the sediment storage and mobility in the estuary/bay/lagoon environment

The focus of this task is to examine the role that marsh and shoreline erosion contribute to the sediment budgets of the adjacent open-water estuarine system. Sediments derived from marsh shoreline erosion generally have higher organic matter content than sediments derived from the erosion of barrier islands or delivered by rivers. Understanding the sediment budget in these estuarine...
