Kara M Garvin
Hydrologist Oklahoma - Texas Water Science Center
As a Hydrologist with the New Jersey Water Science Center, my primary research focus has been on surface-water statistics. I've worked on projects to compute low-flow and flood frequency statistics at gaging stations and partial record sites and to develop regional regression equations used to estimate low- flow and flood frequency statistics at ungaged sites. I've developed the StreamStats web application for New Jersey, which allows users to calculate basin characteristics, peak-flow and low-flow estimates for a selected drainage basin. I am a member of the USGS StreamStats Advisory Committee. I am currently working on creating flood inundation maps for stream reaches with known flooding issues in New Jersey. The mapping process uses HEC-RAS surface water models and GIS analysis tools to map the aerial extent and depth of flooding in the stream reaches.

Hurricane Harvey made landfall near Rockport, Texas, on August 25, 2017, as a Category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland, the forward motion of the storm slowed down and produced tremendous rainfall amounts over southeastern Texas, with 8-day rainfall amounts exceeding 60 inches in some locations, which is about 15 inches more than average annual amou
