modeling

Purpose. Modelling environmentally safe bioenergy trends based on national and international pa-tent databases and scientific databases. Methods. Bibliometric method of analysis using the Scopus database and patent databases, model-ing methods using a special visualization software package. Results. An analytical diagram based on the review of patent databases was developed, as well as a model for visualization of interrelationships between clusters of bioenergy development trends as a com-plex solution for environmental protection. Thus, 4 clusters were formed based on data from the Scopus database using VOSviewer software: 1) cluster (red) reveals the environmental problems of changing the direction of implementation of stationary energy sources with the development of bioenergy potential, and the creation of strategies for this development at the level of regions; 2) cluster (yellow) covers the pro-cess of restoration of ecological systems, in particular forests and reduction of CO2 emissions from bioen-ergy; 3) cluster (green) covers the production and use of different types of fuel and energy produced by the introduction and improvement of bioenergy technologies; 4) cluster (blue) covers the impact of bioen-ergy technologies on environmental restoration and purification and reduction of damage from anthropo-genic impact. Conclusions. The analysis of patent databases with cluster visualization based on a bibliometric ap-proach allowed to identify the most promising areas of research in the field of bioenergy solutions devel-opment. Further research will be focused on the development of a lab bench for biogenic gas production with the possibility of complex processing of secondary raw materials and obtaining environmentally safe digestates.

Shown that the multiple regression model interannual changes of average monthlyspeed of wind in Kirovograd in february and august, with maximal robustness to temporary shifts in the future, allow for efficient prediction of the process of preemption, at least 8 years. Decrease of the average wind speeds in the mentioned months, that happened here in the previous thirty years, from 2011 to 2017., stops that would make it more favorable prospects in regigone wind

The scientific justification for universal automated geographic information systems software of soil water erosion models is given, there are examples of its use to assess the risk of erosion of land and the design of optimal anti erosion measures. The basis of the information network laid vector principle, to automatical determine the line flow, catchment basins, slope and exposure to arbitrary points of the territory of the study and take into account the discrete-continuous nature of erosion processes.

For research of intercommunication between the levels of toxicness and muddiness of water were drawn on the results of measuring of component composition and determination of toxicness of sewages of enterprises of the different industries of economy, located on territory of a few areas of Ukraine. It is shown that in each of cases the set of meaningful physical and chemical indexes which correlate with data of biotesting is different and depends on component composition of sewages. The brought results over are base on the use of far of experimental data and have an important practical value for the exposure of reasons of origin of toxic properties of sewages with the purpose of realization of corresponding nature protection measures on their removal.

An example of channel modeling costs in the selected channel section during the spring flood in the basin, likely modeled inundation zone, defined Channel consumption during the summer storm flood. The possibility of computer technology water distribution to assess the ecological condition of surface water bodies and catchment areas.
