NWTOPT NWTOPT

Hyperparameter optimization approaches were applied to improve performance and accuracy of groundwater flow models. Freely available new software, NWTOPT, is described that uses Tree of Parzen Estimators (TPE) and Random Search optimization algorithms to optimize MODFLOW-NWT’s solver settings. We ran 3500 trials on a steady-state and transient model. To quantify the performance of...

Whooping crane migration habitat selection disturbance data and maps Whooping crane migration habitat selection disturbance data and maps

These data and maps were developed to support an effort to understand how whooping cranes (Grus americana) select stopover habitat in the presence of human infrastructure. Location and associated data came from whooping cranes from the Aransas-Wood Buffalo Population, 2010–2016. We marked a sample of 57 whooping cranes with leg-mounted transmitters that acquired locations via the global
