Hydraulic engineering has great significance for the development of the economy today in the world. The progress of countries in the world depends on water management.

Hydrotechnical engineering collects and brings the required quantity of water where and when they are needed. Also, hydrotechnical engineering deals with the protection of the population, industry, infrastructure, etc. from harmful water surpluses (such as groundwater, floods, etc.).

Special importance for the development of the economy are water supply systems, sewage, dam and hydro accumulation, hydropower systems, regulation of river flows and generally environmental protection (surface and groundwater and soil).

To research the hydrodynamic characteristics, such as turbulent shear stress, turbulent kinematic energy, or energy dissipation rate, etc., for the 2-dimensional vertical plane and the 2-dimensional horizontal plane flows by analytical, numerical or experimental study and compare the results among them is the purposes and scope . The applications must be included in the submitted article.
