Abstract: As per Government of India, India is losing 5,334 million tonnes of soil every year due to soil erosion [The Hindu, Nov 26, 2010]. Another survey says soil erosion in India estimated to be occurring on 147 million hectares of land including 94 mha from water erosion, 16 mha from acidification, 14 mha from flooding, 9mha from wind erosion, and 7 mha from a combination of factors. [R. Bhattacharya, Sustainability 2015, 7]. In this study based on mobile river bed setup, plan form development around an island and corresponding soil erosion and deposition are evaluated. Directional current (DCM) and acoustic Doppler Velocity (ADV) meters are used for the field measurements of velocity and turbulence particularly in the interface region between main channel and floodplain. The values of local shear velocity and roughness length for the reach under study being calculated and analyzed using measured velocity data in order to provide a scientific pattern of plan form development.

Abstract: In the present study, singular stress fields in three-dimensional piezoelectric bonded joint with two-real singularities are investigated at a vertex and along a free edge (a singular line) of an interface. A conservative integral formulation is developed for calculating the intensity of singularity at a point located on the singular line of three-dimensional piezoelectric bonded joint. The intensities of the singularities at several positions along the singular line of the interface are determined. The relationships between singular stress fields at the vertex and along the singular line are considered.
