Title: Quantifying the Forms and Driver Functions of Drying Characteristics of Non‐perennial Streams
Abstract: Non‐perennial streams are vulnerable due to hydroclimatic variability, yet nonlinear changes and the process linkages that control stream drying remain insufficiently understood. This dissertation aims to examine historical drying patterns, atmospheric moisture controls, and hydroclimatic dependency pathways in non‐perennial streams across the continental United States. First, the study explores how many streams are experiencing longer dry periods and which eco‐regions are undergoing significant, nonlinear changes with notable breakpoints in recent decades. Additionally, it explores how seasonal dew point temperature and vapor pressure deficit influence overall drying patterns. Finally, the dissertation investigates hydroclimatic dependencies and control mediator pathways that affect no‐flow responses.
