  • Applicability of ground penetration radar (GPR) technique to optimize soil Nail Wall designs 
    Lasan, HLI; Weerasekara, MN; Prashanth, S; Abeysinghe, AMKB; Premasiri, HMR; Samaradivakara, GVI [Conference-Full-text]
    Soil nailing is used to stabilize existing natural slopes or excavations using soil reinforcement technique. Due to lack of information on ground profiles and thickness of soil layers, the required soil nail lengths cannot ...
  • Applicability of pre-heating techniques for recovery of garnet from garnet biotite gneiss 
    Jayakodi, JDSU; Weliwita, BY; Nishanthan, SS; Samaradivakara, GVI; Abeysinghe, AMKB; Rohitha, LPS; Vijitha, AVP [Conference-Full-text]
    In mineral processing industry, the highest energy is consumed by crushing and grinding operations. However, if we can initiate micro cracks in the hard rock pieces in advance, we should be able to reduce the crushing ...
  • Dynamics of the Madu-Ganga Estuary 
    De Silva, UHNH; Somasiri, RBHP; Jayasekara, NNL; Ratnayake, AS; Dushyantha, N; Weththasinghe, SM; Samaradivakara, GVI; Vijitha, AVP; Ratnayake, NP [Conference Full-text]
    Among the estuaries in Sri Lanka, Madu-Ganga Estuary plays a significant role to generate a massive income through tourism. The existing tropical ecosystem attracts the tourists. However, this ecosystem faces problems of ...
  • Fluctuations in groundwater level and corresponding earth resistivity changes 
    Chandrasena, RTPIU; Madushanka, GHSP; Amalan, K; Samaradivakara, GVI; Chaminda, SP; Jayawardena, CL [Conference Full-text]
    The earth resistivity at a known location was frequently measured, through resistivity sounding. Resistivity of subsurface layers could be influenced by the permeability, porosity, transmissivity, composition etc., where ...
  • Software assisted bench blast optimization 
    Bandara, RMCND; Rajapaksha RMCP; Kavirathne, BB; Samaradivakara, GVI; Chaminda, SP; Hemalal, PVA; Dharmaratne, PGR [Conference Full-text]
    Blasting activities in mines and quarries have been placing significant emphasis on the ability to tailor fragmentation to improve downstream process. Achieving the optimum blast design for a particular rock mass type can ...
  • Structures of water column and sediment sub-bottom in the Tangalle Bay, Sri Lanka 
    Weththasinghe, SM; Ratnayake, AS; Dushyantha, N; Ratnayake, NP; Samaradivakara, GVI; Vijitha, AVP [Conference Full-text]
    Water quality parameters and local morphology are important for monitoring aquatic life, and for planning any coastal development project. So far, few studies have been carried out in Sri Lanka for identifying water ...
