  • 210Pb geochronology of sediments from the Guama River and Guajara Bay in the Amazon region, Belem, Brazil

    This study chronologically dated three sediment profiles collected at the mouth of the Amazon River using the 210Pb geochronology method. All profiles were sliced into 5 cm layers and analysed for radionuclides through gamma spectrometry. The results obtained dated the sediments as far back as 65 years. The sedimentation rate was also determined. A subsequent interpretation of the results ...

  • Turbulent Mixing in fine-scale phytoplankton layers: Observations and inferences of layer dynamics

    Turbulence measurements in fine-scale phytoplankton layers in the Gulf of Aqaba (Red Sea) were used to evaluate mechanisms of layer formation, maintenance, and breakdown. Simultaneous profiles of chlorophyll a (Chl a) fluorescence and temperature microstructure were measured in the upper 40 m of a 430 m water column over a 16-d period, using a Self Contained Autonomous MicroProfiler (SCAMP). ...

  • Storm water infiltration in a monitored green roof for hydrologic restoration

    The objectives of this study are to provide detailed information about green roof performance in the Mediterranean climate (retained volume, peak flow reduction, runoff delay) and to identify a suitable modelling approach for describing the associated hydrologic response. Data collected during a 13-month monitoring campaign and a seasonal monitoring campaign (September–December 2008) at the green ...

  • Studying of flow model and bed load transport in a coarse bed river: case study – Aland River, Iran

    This paper describes a mathematical model which solves the 1D unsteady flow over a mobile bed. The model is based on the Richtmyer second-order explicit scheme. Comparison of the model results with the experimental flume data for alluvial steady flow (aggradation due to overloading) and unsteady flow shows that, by using the two-step method of Richtmyer, one can solve the equations, governing the ...

  • Developing dry-weather flow and RDI/I models using regression analysis and unit hydrography

    InfoWorks CS has been used to build an accurate sanitary sewer flow model for Jefferson Parish, Louisiana, despite there being gaps in the available input data. Reliable predictions of the dry-weather and rainfall-dependent flows were derived by using techniques including unit hydrography and regression analysis to determine the required parameters. Jefferson Parish is close to New Orleans in the ...

  • InfoWorks RS underpins forensic analysis of the Boscastle flash flood

    The picturesque small town of Boscastle, on the North Cornwall coast, became a dramatic addition to the UK’s history of extreme flood events on 16 August 2004. On that day, an exceptionally prolonged and intense storm centered on Otterham, near the headwaters of Bodmin Moor, caused levels in its sea-bound exit routes - the river Valency, the Crackington stream, the river Neet and the river Ottery ...

  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • InfoWorks RS aids priority river flood modeling in New Zealand

    Project Background Innovyze’s InfoWorks RS has been the key software in helping to formulate flood risk reduction strategies throughout the Northland Region of New Zealand, an area of approximately 14,000 km2 on the northern tip of New Zealand’s North Island. The Northland Region has a predominately tropical climate. In recent years a number of tropical storms have ...
