Across the US, more than 9,000 locations measure streamflow every 15 minutes all year long. These data points are open and accessible through web services and go back in time to the early 1900s. The National Hydrography Dataset is a US-wide high-resolution map of all stream reaches, rivers, and water bodies in the US, also free and openly accessible.
Streamflow is impacted by precipitation, snowmelt, controlled release at upstream dams, evaporation, human consumption, among others, many of which are also documented and observed by federal agencies and other organizations. Large storm events can have big impacts on streams and rivers, causing high water and flooding. Map water data and show people how humans and the environment impact streams and rivers.
Check out the US Geological Survey’s WaterWatch for inspiration in terms of possible water visualizations: http://waterwatch.usgs.gov/.
Animate or visualize changes in streamflow across the US through time on a GIS layer of the stream and river network. The National Water Information System NWIS provides current and historical streamflow data and the National Hydrography Dataset Plus NHDPlus provides a geospatial hydrologic framework of the nation’s stream and river network.
- Bonus 1: Visualize extremes in streamflow data together with storm track data for thunderstorms or hurricanes or other events using NOAA’s Storm Events Database or NOAA’s hurricane database
- Bonus 2: Choose your own event! Many human and natural events control streamflow- you can choose a driver of interest and map its effect of streamflow.

There are two main parts of the challenge: API - All of the data is scattered among a lot of websites, none of which offer API. The first step is to create scripts which draw the information from these sites, store it in a database and offer an API which allows users to query the data and rece... Visit Project

# Flow, Baby, Flow! We hope to make an engaging web application which visualizes USGS data on stream flow rates. You can see our work at [our website]. We will be pulling in data about daily flow rates for US states from USGS NWIS web services. Once we have extracted the daily flow rate ... Visit Project
[WaterViz.com](http://waterviz.com) aims to provide an intuitive view of the current and historic state of water in the conterminous United States. To do so, it presents all of the relevant information in a mapped form. A walk-through video is [here](https://youtu.be/67HwP_YmUwQ) and a video s... Visit Project
We are an international group of people from China, Germany, the Netherlands and of course New Zealand. We’ve all met at Movio where we found we share a common interest in big data and visualisation. There is so much cool data out there and translating that into meaningful stories is what we love... Visit Project
