Abstract Experimental catchments are fundamental elements in hydrological sciences as they provide key data for putting forward and testing hypotheses, developing theories, constraining models, making predictions. Significant progress catchment hydrology stemmed from field measurements but increasing costs risks associated with work the availability of big based on remote sensing, machine learning, a plethora well observations deriving previous current sites, raises questions whether running an experimental still provides individual community benefits past. In this commentary, I highlight advantages keeping alive propose personal 10‐step “recipe” to set up new manage sustain it long term. These suggestions can be useful both young less researchers who open facing challenge measuring processes willing offer scientific evidence advancing our knowledge hydrology.

ABSTRACT The Conceptual‐Functional Equivalent (CFE) to the National Water Model (NWM) serves as a baseline rainfall‐runoff model in Oceanic and Atmospheric Administration (NOAA)'s Next Generation Framework (NextGen). CFE performs similarly earlier version of NWM, allowing comparisons with new models introduced future versions. In addition streamflow, NWM outputs other hydrologic variables including soil moisture. Soil moisture plays key role simulating seasonal processes process‐based models; therefore, it is imperative evaluate against observed data. However, incorporating situ data, which highly spatially variable, into calibration process may compromise streamflow results. We investigate how evaluation, observations, affects CFE's ability reproduce evaluated on two experimental watersheds using both traditional signature‐based performance metrics for Results showed that data enhances reproducibility overall patterns without sacrificing streamflow. Calibration alone was insufficient patterns. recommend when available improve predictions.
