Analysis of Meandering River Morphodynamics Using Satellite Remote Sensing Data—An Application in the Lower Deduru Oya (River), Sri Lanka
Basnayaka, Vindhya; Samarasinghe, Jayanga T.; Gunathilake, Miyuru; Muttil, Nitin; Hettiarachchi, Dileepa C.; Abeynayaka, Amila; Rathnayake, Upaka (Peer reviewed; Journal article, 2022-07-16)River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics of these rivers are complex due to the temporal variation of flows. ... -
Comparing Combined 1D/2D and 2D Hydraulic Simulations Using High-Resolution Topographic Data: Examples from Sri Lanka—Lower Kelani River Basin
Samarasinghe, Jayanga T.; Basnayaka, Vindhya; Gunathilake, Miyuru; Azamathulla, Hazi M.; Rathnayake, Upaka (Peer reviewed; Journal article, 2022-02-17)The application of numerical models to understand the behavioural pattern of a flood is widely found in the literature. However, the selection of an appropriate hydraulic model is highly essential to conduct reliable ... -
Planform Changes in the Lower Mahaweli River, Sri Lanka Using Landsat Satellite Data
Basnayaka, Vindhya; Samarasinghe, Jayanga T.; Gunathilake, Miyuru; Muttil, Nitin; Rathnayake, Upaka (Peer reviewed; Journal article, 2022-10-03)Major development projects along rivers, like reservoirs and other hydraulic structures, have changed not only river discharges but also sediment transport. Thus, changes in river planforms can be observed in such rivers. ...
