"No Flow? No Problem! Drivers of Flow and Long-Term Change in Non-Perennial Streams"
Non-perennial streams and rivers account for over 50% of global river network length, but are poorly understood relative to their perennial counterparts. This lack of understanding of the hydrology of non-perennial streams has led to substantial uncertainty in how they should be managed and governed. This talk synthesizes work at scales ranging from an individual reach to a cross-continental analysis to explore the drivers of flow in non-perennial streams, with a particular focus on feedbacks between non-perennial streams and groundwater resources. Using a mixture of continental-scale data synthesis, machine learning approaches, numerical models, and detailed field investigations, we find that the flow regimes of non-perennial have changed significantly through time, and that climate and human actions interact to control flow regimes at scales from the reach to the continent.
