FloodNet: Street Flooding Events Measured by FloodNet Sensors
For the FloodNet data collection page, please follow this link. Data presented here were collected by the FloodNet project, which is a collaboration between researchers at academic institutions (New York University and the City University of New York) and NYC government agencies (NYC Department of Environmental Protection, Mayor's Office of Climate & Environmental Justice, Office of Technology & Innovation), working with NYC residents. Data on flood water depth were collected by FloodNet sensors in one minute intervals, then analyzed to develop the flood event summary statistics presented here. A flood event is defined as a series of water depth measurements greater than 10 mm; all measured flood events presented here have undergone QC by a member of the FloodNet team. See attached data description document for more details on data collection, analysis & the publication to cite if using the data or including it in any publication or public presentation. More information on the FloodNet project can be found here: https://www.floodnet.nyc Visualization of the data in an online data dashboard can be found here: https://dataviz.floodnet.nyc

Columns
Each source column, with the name and type we use to store it.
0 of 13 columns carry a concept; 13 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
