Detention-based green roofs for stormwater management under extreme precipitation due to climate change
Hamouz, Vladimir; Pons, Vincent; Sivertsen, Edvard; Raspati, Gema Sakti; Bertrand-Krajewski, Jean-Luc; Muthanna, Tone Merete (Peer reviewed; Journal article, 2020)Rooftops cover a large percentage of land area in urban areas, which can potentially be used for stormwater purposes. Seeking adaptation strategies, there is an increasing interest in utilising green roofs for ... -
Effects of reduced organic matter loading through membrane filtration on the microbial community dynamics in recirculating aquaculture systems (RAS) with Atlantic salmon parr (Salmo salar)
Fossmark, Ragnhild Olsen; Vadstein, Olav; Rosten, Trond Waldemar; Bakke, Ingrid; Koseto, Deni; Bugten, Anette Voll; Helberg, Gaute Alexander Nedberg; Nesje, Jenny; Jørgensen, Niels O.G.; Raspati, Gema Sakti; Azrague, Kamal; Østerhus, Stein Wold; Attramadal, Kari (Peer reviewed; Journal article, 2020)A key challenge in recirculating aquaculture systems (RAS) is the accumulation of particulate organic matter, especially the fine and colloidal fraction due to low removal efficiency of today's technology. The supply of ... -
Framework for the documentation of nature-based solutions for stormwater management
Raspati, Gema Sakti; Bruaset, Stian; Azrague, Kamal; Ugarelli, Rita Maria; Muthanna, Tone Merete; Time, Berit; Sivertsen, Edvard (Peer reviewed; Journal article, 2023)Nature-based solutions (NBSs) are widely implemented for stormwater management; as such they have become important assets that require proper asset management at different stages of their service life. Hence, there is a ... -
Potential of Biofilters for Treatment of De-Icing Chemicals
Raspati, Gema Sakti; Lindseth, Hanna Kristine; Muthanna, Tone Merete; Azrague, Kamal (Journal article; Peer reviewed, 2018)Organic de-icing chemicals, such as propylene glycol and potassium formate, cause environmental degradation in receiving water if left untreated, due to the high organic load resulting in oxygen depletion. Biofilters are ... -
