Pollution has become a matter of grave concern at present with all the components of the environment laden with pollutants largely from anthropogenic sources and unplanned urbanization. Inland wetlands are very delicate ecosystems and encompass a variety of water bodies, namely ponds, rivers, swamps, etc. They house some unique floristic patterns that are crucial in the primary productivity and maintaining a balance of the wetland ecosystem. In addition to it, the inland water bodies are also productive and are of immense importance to humans. The inland wetlands are also an integral part of boosting the economy of the region as they support a number of industries including fishing and recreation. Thus pollution of water bodies has impacted the human race in a deleterious manner. This chapter is an attempt to overview the inland water bodies, their biodiversity pattern, pollution, and their effect on flora at large.

<p>A parameterization of the Prandtl number as a function of the gradient Richardson number is proposed in order to correctly take into account stratification when calculating the thermohydrodynamic regime of inland water bodies. This parameterization allows the existence of turbulence at any values ​​of the Richardson number.</p><p>The proposed function is used to calculate the turbulent thermal conductivity coefficient in a k-epsilon mixing scheme. Modification is implemented in the three-dimensional hydrostatic model developed at the Research Computing Center of Moscow State University.</p><p>It is demonstrated that the proposed modification (in contrast to the standard scheme with a constant Prandtl number) leads to smoothing all sharp changes in vertical distributions of turbulent mixing parameters (turbulent kinetic energy, temperature and thickness of the shock layer) and imposes a Richardson number-dependent relation on the empirical constants of k-epsilon turbulent mixing scheme.</p><p>The work was supported by grants of the RF President’s Grant for Young Scientists (MK-1867.2020.5) and by the RFBR (19-05-00249, 20-05-00776). </p>
