Cost-Effective Hybrid Groyne Series for Riverbank Erosion Prevention Avishek Goswami, Hriday Mani Kalita Clean Soil Air Water, 2025 Groynes are widely used river training structures and have proven effective in flow regulation and bank protection. Recently, hybrid groynes have gained popularity in the field of river training engineering. However, systematic approaches for their optimal design and placement remain limited. In the present work, a linked simulation–optimization model is proposed to determine cost‐effective hybrid groyne series. At the same time, it also ensures the riverbank stability. The flow simulation model solves the unsteady equations of open channel flow. The optimization model is formulated here in three different formulations to handle different real‐field issues. The first formulation is designed to provide complete flexibility in determining all the decision variables, that is, the groyne type, number, length, and position. The second formulation defines some fixed locations of the groynes on the vulnerable river reaches and the optimization model determines the best value of the rest decision variables. The third formulation, however, fixes the groyne types, lengths, and numbers, and the optimization model determines the optimal locations of the same. The proposed optimization models are solved here using the binary coded genetic algorithm (GA). The model is then applied for two hypothetical test cases and reliable results are derived. Out of the three formulations, the first formulation is found to behave more robustly because of no restrictions imposed. Compared to previous optimization studies which focused on individual, uniform, and straight groyne types, the present framework introduces a generalized tool for designing hybrid groyne series.
Best groyne series as countermeasure against river bend scour Kaushik Bora, Hriday Mani Kalita Proceedings of the Institution of Civil Engineers Water Management, 2021 A new approach for finding a cost-effective combination of groynes in a channel bend for the prevention of bend scour is presented. A linked simulation–optimisation model is proposed for this purpose. The morphological flow simulation model was developed by solving the shallow-water equations and the Exner sediment continuity equation in a boundary-fitted coordinate system. The optimisation model was developed utilising a binary-coded genetic algorithm. The proposed model can automatically provide a cost-effective groyne series in terms of their number, length and position in any vulnerable channel bend. A constraint in terms of bend scour is also incorporated in the optimisation model, which allows the optimisation model to obtain the best groyne combination for no bend scour. To appraise the performance of the model, it was applied to a hypothetical vulnerable channel bend. The model produced the minimised cost of installation of the groyne system at that location, at the same time as making the location free from bend scour.
A simple and efficient numerical model for simulating one dimensional dam break flows Hriday Mani Kalita International Journal of Hydrology Science and Technology, 2020 A semi implicit finite difference scheme is presented in this paper for simulation of dam break flow over undulated bed. For this purpose, the one dimensional (1D) governing equations of shallow water flow, in a deviatoric version is solved here. One of the main important features of the present model is that, no special treatment is required here to deal with the offending friction slope source term for very less water depth. Regarding the bed slope term also, simple central difference approximation is sufficient to handle undulated channel bed. To investigate the performance of the present model in diverse situations, it is used to replicate different dam break test problems including one of known analytical solution and two experimental dam break cases. A detail analysis of the results show that the model capable is of producing good quality results for varied conditions. A sensitivity analysis is carried out for the damping parameter and an optimal range is proposed for it.
A semi-coupled model for morphological flow simulation in river bend K. Bora, H. Kalita Journal of Applied Fluid Mechanics, 2020 This paper presents a new efficient and robust numerical model for morphological flow simulation in river bends. The hydrodynamic model is developed by solving the two dimensional (2D) shallow water equations using a total variation diminishing (TVD) MacCormack predictor corrector scheme. The present TVD method is very simple and provides accurate results free from numerical oscillations near sharp gradient. The effective stresses are modeled by using a constant eddy viscosity model. The sediment transport model solves the Exner equation using a simple forward time and central space (FTCS) finite difference algorithm. The sediment transport model incorporates the helical flow and the transverse bed slope effects on the sediment direction computation. These models are coupled using the semicoupled approach. The present semicoupled model is used to replicate two popular experimental test cases of both tight and loose channel bends. The obtained results in terms of bed level variation reveal that the model can accurately simulate several features of the bed changes such as oscillations of the transverse bed profile with the formation of point bars and pools along the banks. The values obtained for three widely used statistical parameters show the applicability of the present model for this type of complex scenarios.
