How Does the Hurricane Harvey Deposits Compare to Past Brazos Subaqueous Delta Flood Deposits
MetadataShow full item record
Hurricane Harvey brought over 100 cm of rain to the lower drainage basin of the Brazos River and resulted in the highest discharge event in the recorded history of the river. On Sept. 10th, 2017, during the waning phase of the flood, we were able to collect a series of 15 box cores and 14 surface/bottom water samples. We were also able to collect water column profiles of temperature, salinity, turbidity, and dissolved oxygen while participating in a research cruise aboard the R/V Pelican. This data is part of a larger time series that began after the 2015 and 2016 floods and will continue with a follow up coring cruise scheduled for October 28, 2017. By investigating the sediment grain size, flood layer thickness, suspended sediment concentrations, and plume dynamics, we hope to gain a better understanding how and where the initial flood pulse was deposited. For this study, I hypothesize that the Harvey flood layer will have the largest flood deposit compared to past deposits.
