Research Overview
My recent and current research interests comprise various topics of Environmental Fluid Mechanics with particular focus on:
- Turbulence in open-channels, rivers, estuaries, and coastal areas
- Benthic boundary layers, water-sediment interfaces, and sediment transport (cohesive/non-cohesive), including sand wave dynamics, turbulence-sediment interactions, erosion, re-suspension, flocculation, and bed particle dispersion
- Flow-biota interactions and transport processes (periphyton, moss, mussels, macrophytes, invertebrates, fish)
- Hydraulic resistance and channel stability in gravel-bed and sand-bed rivers
- Overland flow hydrodynamics and soil erosion
- Hydraulic instrumentation and measurement techniques
- Channel networks, meandering and braided channels, granular surfaces, and Mars topography
