Summary

Our objective was to model frequency of low-pulse events on small, ungaged streams in the Upper Colorado River Basin. Modeling streamflows is an important tool for understanding landscape-scale drivers of flow and estimating flows where there are no gaged records. We focused our study in the Upper Colorado River Basin, a region that is not only critical for water resources but also projected to experience large future climate shifts toward a drier climate. We used a random forest modeling approach to model the relation between frequency of low-pulse events on gaged streams (115 gages) and environmental variables. We then projected frequency of low-pulse events to ungaged reaches in the Upper Colorado River Basin using environmental [...]

Purpose

Modeled frequency of low-pulse events (number of events per year less than 5 percent of mean annual streamflow) on small, ungaged streams in the Upper Colorado River Basin. Our map projections are useful for scientists, land owners, and policy makers to understand current hydrology in the Upper Colorado Basin and to make informed decisions regarding water resources.
