At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

<em>Seagrasses habitats have both physical and ecological functions that support adjacent waters qualities and its dwelling organisms. There are varies of pressure on seagrass environmental, especially due to people activities that could decrease its function and habitat stabilities. The study aimed to determine about seagrass habitat stabilities from its species composition and/or densities. Line transect-plots and exploration methods were used in five locations of Manokwari coastal waters, that were, Andai, Rendani, Wosi, Briosi, and Tanjung Manggewa. There are five pioneer species (Cymodocea rotundata, Halodule pinifolia, H. uninervis, Syringodium isoetifolium, Halophila ovalis) and 3 climax species (Cymodocea serrulata, Enhalus acoroides, Thalassia hemprichii). The pioneer only found in Andai and Wosi, however both pioneer and climax encountered in three other locations. In Rendani and Tanjung Manggewa higher density of climax species (T. hemprichii) were 617.7 and 828.0 stands m-2, respectively, although in Briosi the higher pioneer (C. rotundata) of 570.7 stands m-2. These conditions showed that seagrass habitat in Rendani and Tanjung Manggewa are more stable compared to Briosi, as well as Andai and Wosi. It concluded that pioneer species found in newly formed habitat or disturbed, on the other hand, climax in more stable habitat.</em>

Conceptual Foundations

Cheboksary reservoir impact to the coast is manifested in the geophysical impact associated with abrasion activities. Geomorphological area of influence at the moment reaches a width of about 40 m, where are the coasts reformation (erosion, collapse, slumping, sliding, transfer or accumulation of sediments, waterlogged processes). Hydrogeological impact is effect on the level of groundwater. We have proposed the conceptual foundations of functional zoning of the reservoir banks that will help to optimize its operation. Selection zones came in accordance with the principles of landscape planning: 1. The zone of strict water protection: the main purpose – preservation of needing special protection areas. 2. The zone of moderate restrictions: preservation extensively used landscapes. 3. The zone of partial restrictions: improving the pre-emptive particularly vulnerable areas and changing intensity or type of use. 4. The zone of conservation of natural components in agricultural landscapes: ensuring health of the natural environment in the habitats used in agricultural economy. 5. The zone of preservation of vacant space and the natural environment in the settlements: to maintain the required quantity and quality of available green space in the large towns. 6. The zone of improving heavily used areas: elimination of harmful stress and environmental sanitation in the countryside where economic activities and the lack of measures to reduce their risks lead to degradation natural system.

Planning Methods

One of major factors of deterioration in a microclimate of urban development in the conditions of the Rostov region, is degradation of landscapes owing to violation of water balance of the territory. In article the main reasons for violation of water balance which included natural features of the region, a consequence of anthropogenic influence, climatic changes, etc. are considered. Examples from the world practice of urban planning, which show the relevance and effectiveness of compensation for the effects of anthropogenic im-pacts and climate change using planning methods, are given. The experience of the United States, the Nether-lands, Canada and other countries that use water-saving technologies in planning is considered. The rela-tionship of urban planning and the formation of sustainable urban landscapes is shown. The integration of water-saving technologies into the urban environment can be a means of optimizing landscapes and a means of creating unique urban spaces. Reclamation of the urban landscape of low-rise buildings is a necessary step in creating a modern and comfortable urban environment in the conditions of the Rostov region. Meth-ods are proposed to compensate for negative changes in urban landscapes that can be applied at the stage of urban planning. As well as the proposed methods can be applied in the reconstruction of urban low-rise buildings. The considered methods concern not only urban landscapes, but also agricultural landscapes that surround small and medium-sized cities of the Rostov region. In article the author's concept of the organiza-tion of the low housing estate on a basis Urban- facies is submitted. Planning methods of regulation of water balance of the territory on the basis of models the ecological protective of landscapes are offered: an ecolog-ical core, an ecological corridor and an ecological barrier and also analogs from town-planning practice are considered. The reclamation of urban landscapes based on urban planning methods for regulating the water balance of the territory will allow creating unique urban spaces that are resistant to local climatic conditions and the possible consequences of climate change.
