The shear shallow water (SSW) model introduces an approximation for shallow water flows by including the effect of vertical shear in the system. Six non-linear hyperbolic partial differential equations with non-conservative laws make up this system.

We investigate two systems of conservation laws that explain the chemistry process of isolating a single component from a mixture using column chromatography. We design the modified Rusanov (mR) approach for solving these chromatography models. This

This paper examines a one-dimensional (1D) model that appears in arterial blood flow. The mathematical model for blood flow via arteries is similar to that of unstable incompressible flows in thin-walled collapsible tubes. We present the Riemann inva

We suggest a group of reliable and efficient finite volume techniques for solving the Suliciu relaxation model numerically. Namely, we have developed the modified Rusanov (mR) method to solve this model. This system is divided into two parts, the fir

The Brio system is a nonlinear system of conservation laws that is used to analyze plasmas. The current research presents numerical solutions to this model exposed to initial conditions using the generalized Rusanov (G. Rusanov) scheme. This method i

In this work, we consider the model of shallow water equation with horizontal density gradients. We develop the modified Rusanov (mR) scheme to solve this model in one and two dimensions. Predictor and corrector are the two stages of the suggested sc

The biochar application has been reported to have a positive effect on crop yield and nutrient utilization. However, the effects of the joint application of biochar and nitrogen (N) on soil physical properties, fruit yield, quality, crop water produc

The main motive of this work is to introduce a numerical investigation for the one and two-dimensional (1D/2D) Chaplygin gas model. Namely, we developed the non homogeneous Riemann solver (NHRS) method to solve these models. After discussing the Chap

We consider the isothermal Euler model with non-vacuum initial data. We extract the Riemann invariants of the isothermal Euler model, which admits vital applications. We also design the modified Rusanov (mR) scheme to solve the isothermal Euler model

Mining operations accelerate ecological damage in alpine mountain locations by contributing to soil erosion and nutrient loss in the freeze-thaw (FT) climate. However, limited studies have been conducted to reduce the soil erosion and nutrient loss i
