It should be recognized that the Republic of Azerbaijan has a leash of 14% of the water supply in the whole of Transcaucasia. Then, when the interim water balance of the republic is 32.29 million km 3 . However, in the best case, the water years with a 95% supply due to neighboring water atheria, this figure reaches up to 20 million km, as well as in shallow years, the republic will only reduce it to 17.0 million km3. water. That is, there is an acute shortage of water in the country. For the rational use of already limited water resources, it is necessary to switch to modern progressive irrigation methods using small-scale mechanization and automation of irrigation. The current technical equipment for irrigation does not always meet the requirements of the specific conditions of Azerbaijan. Our proposed irrigation system can be successfully used in various soil, climatic and difficult geographic conditions in the country, which was tested in the country with certifying indicators as crop yields increased to 38-50% when irrigation water of 3 or more was saved times while maintaining the ecological balance of the environment.

This paper studies the Floating-Gate MOSFET (FGMOSFET) for its importance in biomedical engineering and many modern low-power applications. A practical model for FGMOSFET is highly needed to be used in circuits simulators. In this work, a spice model for FGMOSFET is introduced and can be inserted in any circuit simulator such as Spector and various SPICE programs (i.e. HSPICE, WinSPICE, etc.). Firstly, the parasitic capacitances needed for FGMOSFET is revised for 0.13um CMOS technology. Secondly, a model for both mutual and output transconductance is represented. The model is based on n-channel FGMOSFET and valid from linear to saturation regions. The model considers velocity saturation as short channel effect and bulk charge due to drain-to-source voltage as second order effect. The results were verified by the spice simulation BSIM3v3 model in Cadence. The model is not a charge conservative.

The article examines the issues of the possibility of studying erosion and its control. The study proved that the development of soil erosion is based on the forming impact of natural and anthropogenic factors. The degree of potential danger and the possibility of prevention, taking into account the preservation of the environmental situation in the foothills of the Upper Shirvan in the example of the Shamakhi district of the Republic of Azerbaijan, were studied. The main tasks of the study were the determination of the amount and the degree of development of eroded and erosion-prone soils of the foothill zones, carried out on the basis of soil. Key words: erosion, soil; the assessment of the degree of erosion is environmentally hazardous; anti-erosion measures.
