Conclusions• Storm events can greatly influence the water
quality such as salinity, DO, etc in downstream
estuary.
• There would be a delay in the change of water
quality after a storm event.
• It will take about 5 months for an estuary to recover
from storm, with little permanent effect
![Page 21: Influences of Storm Events on Mission-Aransas Estuary and the Recovery](https://reader033.fdocuments.us/reader033/viewer/2022061509/56815f17550346895dcde2d1/html5/thumbnails/21.jpg)
Future Work• Compare the change in salinity in different gauge
stations which serve different functions in the estuary.
• Provide interpolation of salinity in estuary before and
after storm
• Storm influences on estuarine ecosystem –
biodiversity, composition and function of communities.
