The article discusses the methods of treatment of water contaminated with pharmaceuticals and the importance of purification for the environment and humans.

The article discusses a method for determining the duration of full or partial emptying (filling) of reservoirs.

In the calculation, a hydraulic method was used for calculating the full or partial outflow (filling) of water from a vessel with a variable pressure head.

The article describes the calculation of the results of the chemical-laboratory survey of water samples taken from the Alazani Valley soils using reliability and risk theory. The law of distribution of water sulphate-ion (SO4) 2- and calcium-ion (Ca) 2 + mineralization change function) on Alazani valley bottles is established. Also, on the basis of analysis of theoretical and laboratory data, the reliability of the scientific researches (P) and risk (R) of the scientific research has been established.

Issues of fluid viscosity were first reviewed by Newton and the main laws of internal

friction were offered.

For non-homogeneous (heterogeneous) fluids, which include mudflow mixtures, internal friction is

not subject to Newton's law due to the presence of solid phase particles.  The greater the volumetric or content by weight of the particles of the solid phase, the greater the

entire system's viscosity is affected. The presence of solid phase particles leads not only to the change in

viscosity, but also changes the law itself that characterizes this phenomenon.

This article discusses the features and operation problems in water supply systems,

surpluses on the balance of agricultural organizations. Science-based approaches to optimize the operation of

water supply systems are presented in the article.

For the planning and control of the exploitation water supply systems in agricultural organizations is

recommended to group all repair and maintenance work on the stages. These stages are differing in purpose,

scope and deadlines. For the delegation of powers must be used one of four designed organizational

operating models.

The subject of this study is the physico-mechanical, chemical, mineralogical and

granulometric (particle-size distribution) properties of the samples from the mudflow cone of riv.

Duruji. Experimental research of samples taken at different periods, indicate that granulometric

composition does not change over time (variance of composition is approximately 10%). According to

the research, particles with diameters larger than 30 mm are mainly concentrated in the frontal part of

the mudflow cone, however the smaller particles are spread out equally throughout the entire mass.

Acquired results are coherent with findings of other scientists. Results of the study will allow the

determination of the main dynamic characteristics of mudflows.
