Role Of Vegetated Coastal Ecosystems As Nitrogen And Phosphorous Filters And Sinks In The Coasts Of Saudi Arabia, V. Saderne, M. Cusack, Oscar Serrano, H. Almahasheer, P. K. Krishnakumar, L. Rabaoui, M. A. Qurban, C. M. Duarte
Role Of Vegetated Coastal Ecosystems As Nitrogen And Phosphorous Filters And Sinks In The Coasts Of Saudi Arabia, V. Saderne, M. Cusack, Oscar Serrano, H. Almahasheer, P. K. Krishnakumar, L. Rabaoui, M. A. Qurban, C. M. Duarte
Research outputs 2014 to 2021
Vegetated coastal ecosystems along the Red Sea and Arabian Gulf coasts of Saudi Arabia thrive in an extremely arid and oligotrophic environment, with high seawater temperatures and salinity. Mangrove, seagrass and saltmarsh ecosystems have been shown to act as efficient sinks of sediment organic carbon, earning these vegetated ecosystems the moniker 'blue carbon' ecosystems. However, their role as nitrogen and phosphorus (N and P) sinks remains poorly understood. In this study, we examine the capacity of blue carbon ecosystems to trap and store nitrogen and phosphorous in their sediments in the central Red Sea and Arabian Gulf. We estimated the …

Floating Constructed Wetland For The Treatment Of Polluted River Water: A Pilot Scale Study On Seasonal Variation And Shock Load, Tanveer Saeed, Biprojit Paul, Rumana Afrin,, Abdullah Al-Muyeed, Guangzhi Sun
Research outputs 2014 to 2021
This paper reports the performance of a pilot scale floating constructed wetland (FCW), employed for the treatment of polluted water collected from Buriganga river in Bangladesh. The FCW system included a tank for accommodating collected water and a floating mat with media, to support the growth of two macrophyte species Phragmites australis and Canna indica. Mean mass removal rates of 0.66, 0.76, 0.08, 0.51, 2.49g/m2d were achieved for ammoniacal nitrogen (NH4-N), total inorganic nitrogen (TIN), phosphorus (P), biochemical oxygen demand (BOD), chemical oxygen demand (COD), respectively by the FCW. Nitrogen removal was via nitrification-denitrification processes, whereas filtration-sedimentation appeared to influence …
Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen
Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen
Theses: Doctorates and Masters
From early April 2002 to June 2003, a study was conducted at Wanneroo and Bannister Creek in Perth's metropolitan area (Western Australia), aiming to quantify major sources of nitrogen (N) and phosphorus (P) entering urban residential catchments on two of the major dunal systems. The export of N and P from these catchments in stormwater discharge was measured, allowing investigation of some of the key pathways through which N and P enter the drainage network from the catchment. This information was then used to recommend catchment management approaches to reduce nutrient discharge into stormwater.
