The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.

To better identify the significant processes affecting our coastlines and how those processes create coastal change we have developed a Coupled Ocean – Atmosphere – Wave – Sediment Transport (COAWST) Modeling System, which is integrated by the Model Coupling Toolkit to exchange data fields between the ocean model ROMS, the atmosphere model WRF, the wave model SWAN, and the sedime

In cooperation with the City of Houston, USGS collects, processes, and interprets water-quality, streamflow, and reservoir water elevation and capacity data. These data are collected to better understand the effects of urbanization in Lake Houston, a drinking water reservoir in Houston, Texas.

This tool produces shapefiles that contain the delineated basins, basin characteristics, and flow statistics for multiple sites requested at once by users. Before this tool can be used, the the points of interest will likely need to be edited in GIS so that they are coincident with the stream grid used by StreamStats for delineations and saved to a shapefile.

The Water On-the-Go app has been discontinued. You can view gages near your location using the National Water Dashboard. “Water On-the-Go” was a map-based web application to give people easy access to current conditions in streams across Texas. It was developed to help raise water awareness during floods and normal conditions.
