Spatial and elevation points surveyed for indirect measurements of peak streamflow associated with flooding of September to November 2017 in Puerto Rico

This dataset contains topographic (horizontal and vertical) data for 20 sites, surveyed November 6 to November 28, 2017 as part of documentation of flooding that occurred in Puerto Rico during and after Hurricane Maria (September to November 2017). Hurricane Maria hit the Island of Puerto Rico on September 20, 2017 and was one of the deadliest storms in U.S. history. USGS personnel conducted topographic surveys at selected stream sites to facilitate hydraulic modeling of peak streamflows (or discharges) – termed indirect measurements – using published standard USGS methods. Indirect (post-flood) measurements are used to characterize flood peaks that could not be determined using direct methods (for example current-velocity...

Topographic points surveyed in 2018-19 for step-backwater analysis, in the aftermath of Hurricane Maria in Puerto Rico

This data release provides topographic (horizontal and vertical) data for 58 sites, surveyed March 12, 2018 to July 18, 2019 as part of documentation of flooding that occurred in Puerto Rico during and after Hurricane Maria (September to November 2017). Hurricane Maria made landfall on the Island of Puerto Rico on September 20, 2017 and was one of the deadliest storms in U.S. history. The U.S. Geological Survey (USGS) personnel conducted topographic surveys at selected stream sites for hydraulic modeling studies to establish new stage-discharge relations for sites at which flooding substantially changed the pre-existing relation. The standard-step hydraulic method, often referred to as the step-backwater method,...
