M.; Carter, J.Item Metadata only Daily discharge estimation at ungauged river sites using remote sensing(Wiley, 2014-12-17) Moore, P.; Birkinshaw, S. J.; Kilsby, C. G.; O' Donnell, G. M.; Hardy, A. J.; Berry, P. A. M.A methodology is developed to estimate daily river discharge at an ungauged site using remote sensing data. Use is made of ERS-2 and ENVISAT satellite altimetry to provide a time series of river channel stage levels and longitudinal channel slope and Landsat satellite imagery to provide a range of channel widths over a 50 km reach of river. The data are substituted into the Bjerklie et al. (2003) equation, which is based on the Manning's resistance equation and has been developed using a global database of channel hydraulic information and discharge measurements. Our methodology has been applied at three locations on the Mekong and Ob Rivers and validated against daily in situ discharge measurements. The results show Nash–Sutcliffe efficiency values of 0.90 at Nakhon Phanom and 0.86 at Vientiane on the Mekong, and 0.86 at Kalpashevo on the Ob.Item Metadata only The DNSC08GRA global marine gravity field from double retracked satellite altimetry.(Springer, 2010) Andersen, O.

G.; Benveniste, J.Satellite radar altimeters have an established and increasingly vital role in monitoring the Earth’s surface inland water resources. This paper analyzes two years of EnviSat burst echoes (which have 3.9-m nominal along-track separation) over rivers, lakes, and ephemeral water globally to assess the increase in monitoring potential afforded by the higher pulse repetition frequency (PRF) of the next generation of synthetic aperture radar altimeters and investigate spatial burst correlation. Burst echoes at 1800 Hz are successfully retracked with no waveform averaging. The conclusion is that the higher PRF allows detection and measurement of water bodies on a far finer spatial scale because water is a very bright reflector at Ku-band and land in general is relatively poor, with pools of water a few tens of meters across being successfully identified.Item Metadata only Global analysis of Envisat RA-2 burst mode echo sequences(IEEE, 2007-09-01) Berry, P.
