Background Ground-based snow monitoring stations have long supported water management, forecasting, and planning. Recent advancements in remote sensing technology have improved the ability to monitor snow cover at broader scales. Satellite imagery, such as that from the Moderate Resolutiion Imaging Spectroradiometer (MODIS), have been used to track...

The streamflow regime is a critical determinant of many ecological and hydrological processes and plays an important role for regulatory purposes. Three regime categories are often used to describe a river reach: perennial, intermittent, and ephemeral. This distinction has important consequences for water resource management, e.g., since the Clean...
