The erosion of the river bank is a complex mechanism and sediment particles are subjected to a number of forces. Among those forces, force of cohesion between the particles plays a very significant role, and, until now, not much progress has been made to analyze the cohesive force in a comprehensive manner. It is imperative that a particle is surrounded by a family of similar sort of particles and ail are bounded together under this force of cohesion. In this article, a review of the already existing equations available for determination of the escape velocity of a particle on the riverbank is made and a new equation has been suggested. The proposed equation takes into account the micro-level variations in the system comprising of a host of particles in dynamic equilibrium.Keywords

A field experiments was conducted to evaluate the effect of different types sowing technique on mustard varieties in Regional Research Station (Hill Zone), Uttar Banga Krishi Viswavidyalaya in the year 2015-16 during Rabi season (Dec-Feb). The aim of the present study was to evaluate three varieties viz., NC 1, PS 28 and Piloo NG in Hill Zone of West Bengal with respect to yield attributing characters. Mustrad seeds were sown by broadcasting as well as line spacing (25cm×5-7 cm). It was found that the mustard yield and yield attributing characters in line spacing was higher (1.35 t/ha) compared to broadcasting (1.33 t/ha). It was also observed that PS 28 have the best yield (1.42 t/ha) in comparison to NC 1 (1.31 t/ha) and Piloo NG (1.30 t/ha).Keywords
