Summary

These full time-series period statistics data were compiled for monitoring riparian zone trends and changes in the lower Colorado as part of a study to document riparian ecosystem health and its water use. Our study evaluated the short and long-term effects on the river's vegetation of drought and hydrological processes in this dryland region. Because of the landscape changes, we explored remote sensing-based change analysis techniques and data to develop time series data of the Colorado River riparian corridor vegetation greenness, phenology, and water use since the year 2000. We divided the river into five Reaches (R3..R7) to separate between the different land covers, management conditions, and general geospatial and hydrological [...]

Purpose

The purpose of these time-series period statistics data are to provide estimates of the riparian woodland area ecosystem health and its water use for the Lower Colorado River between Hoover and Morelos dams over the past 21 years. The end users that utilize this information are both land and water managers for the federal and tribal governments, as well as NGOs. These data are also important for relative estimates of water use using other methods such as by researchers primarily interested in agricultural methods as applied to other land cover types (e.g., riparian).
