Control of algal blooms in reservoirs with a curtain: A numerical analysis

Asaeda, T; Pham, HS; Nimal Priyantha, DG; Manatunge, J; Hocking, GC

Two vertical curtains, having depths to cover the epilimnion thickness, were installed across the Terauchi Dam Reservoir in the western island of Japan to curtail the nutrient supply from nutrient-rich inflows to the ...
Evaluation of environmental impacts of solar pv systems withconceptual life cycle assessment and recycling of endof- life pv panels

De Alwis, ARI; Manatunge, J [Conference-Abstract]

Although numerous dialogues on the recycling processes of PV panels have been in the limelight, their progress has been slow due to the lack of institutional support and the lack of robust legislation within countries. ...

Kinetic modelling and performance evaluation of vertical subsurface flow constructed wetlands in tropics

Weerakoon, GMPR; Jinadasa, KBSN; Manatunge, J; Wijesiri, B; Goonetilleke, A [Article-Full-text]

The design of vertical subsurface flow (VSSF) constructed wetlands (CWs) uses kinetic models to calculate the area based on the kinetic reaction rate constant (k) specific to local environmental conditions and target ...
Livelihood rebuilding of dam-affected communities: Case studies from Sri Lanka and Indonesia

Manatunge, J; Takesada, N; Miyata, S; Herath, L [Article-Full-text]

This paper discuss two cases of resettlement related to dam development: the Saguling project in West Java and the Kotmale project in Sri Lanka. Resettlers of these two projects were offered new livelihoods created by the ...
