Ms Liubov Meshkova is Visiting researcher within Geography and Environment at the University of Southampton.

BSc. Honours in geology with specialization in Geo-ecological cartography and GIS from Tomsk State University, Russia

Previous experience includes working as a GIS specialist in environmental monitoring (Russia), GIS training consultancy and technical translation work (UK).

The research is focused on geomorphology of the multi-channel mixed-bedrock alluvial section of the Mekong River in the north-eastern parts of Cambodia, South East Asia and comparison of its planimetric characteristics to these of other multi-channel rivers of a different nature. In order to complete a portrait of the river at the high level of details new data on morphology, geology and sediments were obtained during field surveys of a 120 km river section in Cambodia and combined with information from published literature and interpretation of available remote sensing images. In addition, luminescence dating of the sediments from a palaeochannel and the sediments constituting the surfaces of alluvial islands and an adjacent plain elucidate development of the Mekong in this region. This process has enabled to update and clarify knowledge on morphology of observed islands and floodplain, comprehensive geology and tectonic structures, hydrological regime and land cover of the Mekong in historical context.

The planform characteristics of the Mekong River network are compared using analysis of channel network and islands configurations with the fluvial patterns of the Orange River (South Africa), Upper Columbia River (Canada) and the Ganga River (India, Bangladesh). These rivers are selected as examples of anastomosed mixed bedrock alluvial, anastomosed alluvial and braided alluvial rivers respectively. Network parameters such as channel bifurcation angles asymmetry, sinuosity, braid intensity and island morphometric shape metrics are compared and contrasted between bedrock and alluvial systems. In addition, regional and local topographic trend surfaces produced for each river planform help explain the local changes in river direction and the degree of anastomosis, distinguish the bedrock-alluvial rivers from the alluvial rivers. Finally, the description of the channel planform and the network metrics provide a quantitative means to describe the distinctive character of the Mekong in comparison with other well known large alluvial anastomosed river systems in similar environmental settings.
