Deriving fluxes of suspended particulate matter in the Humber estuary, UK,using airborne remote sensing

This study exploits the use of airborne remote sensing for the assessment o f coastal and estuarine environments, in particular the Humber Estuary. A C ompact Airborne Spectrographic Imager was used to acquire a series of fligh tlines across the mouth of the Humber estuary during the flood on 10 August 1995. The flightlines encompassed the flux curtain, which consists of five moorings set out across the estuary to monitor flux of Suspended Particula te Matter (SPM). The images were radiometrically, atmospherically and geome trically corrected and SPM concentrations in surface waters derived. SPM fl ux was assessed by incorporating image-derived SPM concentration values wit h velocity results from a hydrodynamic model, These results were integrated over depth and an estimate of total flux determined for a 2-h section of t he flood.
