Estimating Discharge In Low-Order Rivers With High-Resolution Aerial Imagery, Tyler V. King, Bethany T. Neilson, Mitchell T. Rasmussen

Publications

Remote sensing of river discharge promises to augment in situ gauging stations, but the majority of research in this field focuses on large rivers (>50 m wide). We present a method for estimating volumetric river discharge in low-order (wide) rivers from remotely sensed data by coupling high-resolution imagery with one-dimensional hydraulic modeling at so-called virtual gauging stations. These locations were identified as locations where the river contracted under low flows, exposing a substantial portion of the river bed. Topography of the exposed river bed was photogrammetrically extracted from high-resolution aerial imagery while the geometry of the remaining inundated portion …

Annual Report 2018, Casco Bay Estuary Partnership

Publications

CBEP has been collaborating for over 25 years with a multitude of partners working hard to protect Casco Bay. 2018 brought us new and exciting collaborations.

The Casco Bay Nutrient Council, convened by CBEP, met for almost two years and produced a report that laid a path forward for all partners to tackle nutrient pollution.

CBEP worked closely with the EPA to establish the Casco Bay Monitoring Network, made up of over 20 member organizations, aimed at coordinating and upgrading monitoring in the Bay. The Network is currently updating the Casco Bay Monitoring Plan.

CBEP is an active participant in …
