Introduction
At present, the applied significance of such research is very well proven in the activities in spatial planning and design, tourism and in general in all spheres of modern life Gurkova [1]. Bulgarian tourists and nature lovers themselves have created some remarkable ecotrails, surrounded by beautiful scenery of mountains, waterfalls, forests, cliffs, and gorges. Landscape architects here are debtors of the society in this regard remain static observers of tourism issues.
There are, however, several guidelines we can use to help improve the scenic aesthetic composition refers to the way the various There, the field of surveillance is the most spacious and gives a good choice of perspective. Since each level of monitoring, we have a different horizon and a different distance to a pictorial plane. This determines as important different plans in space examined in great detail in Bell [2] and in Minghua, et al. [3]. It is very difficult to be summarized and systematized all scientific views on the issue of forest landscape perceptions and especially of scenic beauty.
Here are researched and investigated several models of scenic quality Thomas [4,5] that are based on combining parts of reconstructive methods, park perspective, spatial composition, and painting techniques of imagery. They can make design process

ARTICLE INFO ABSTRACT
This article illustrates several specific composition techniques that will improve visual attractiveness of forest landscapes located along rivers and other water bodies and streams. There are presented some results of the analysis of visual characteristics and spatial design of the open spaces and tree plantations in these riparian landscapes. Different situations are considered in terms of the size and shape of the water component of the landscape, and the relief features of the site, and the characteristics of the vegetative cover, etc. This study may help to clarify many issues on the design of ecotrails, and to establish criteria and standards for their construction and their maintenance responsibilities. There are several guidelines we can use to help improve the scenic aesthetic composition refers to the way the various elements in a scene are placed and proportionate. Landscape aesthetic and visual quality can be achieved by some practical tips which have come from such analyzes over time, that study and establish what in general made people focus on landscape beauty. In most cases, this can be an emphasis group of trees, even a single tree. It can also be an architectural element such as a bridge, barrage, or other hydraulic structure. But ultimately the overall composition plays a major role in the scenery aesthetics. The routes planning decision and the overall plant composition are crucial in all situations, with details and highlights in the background.
The theory and practice of the sensuous cognition of landscape qualities is an endless field of research, and any new study like this hope to add a little more to the landscape architect's knowledge and experience on this difficult and complex issue. much easier and the resulting landscape 'picture' -applicable to planning process, respective to landscape design. Such a sufficiently simple, fast, and effective could be called the park design guidelines published in Kosarevskiy [6]. Although visual complexity and aesthetic quality are stretchable concepts the whole picture of a perfect landscape comes from the well thought out and successful park design drawing and is responsible of the subsequent realization in real space. That is why the landscape planning itself as a pictorial space is essential for the panoramic view recovery. The theoretical considerations regarding studied in this paper problems are influenced by similar publications in ecology, especially in McCormack [7] and in Van Oosten, et al. [8], which proposed that increasing ecological diversity is correlated with increasing stability, and hence with environmental quality.
Other researchers Watts [9,10] have explicitly linked these two ideas, proposing that ecologically stable, i.e., healthy, landscapes are intrinsically beautiful.
This paper takes one of these relationships, that between visual complexity and perceived scenic quality, here termed scenic beauty, for further investigation. To focus properly on ways to enhancing the riparian forest and meadow landscape aesthetics and to understand public perception of scenic beauty we also studied many methodologies that has often been applied to evaluate forest scenic beauty Schroeder [11][12][13]. It is always difficult and very relative to postulate the principles of the aesthetic qualities of the landscapes and, in particular, the riparian forest and meadow landscapes. It is even more difficult to typify human perceptions of landscape attractiveness. As the present study precisely addresses such aspects, the findings of scientific articles such as SAEFL, et al.
[ [14][15][16] are considered. The main objective of the study is to define some principles of landscape design the implementation of which would improve the aesthetic qualities and the visual attractiveness of riparian forest and meadow landscapes.

Material and Methods
This paper is based on the long-term multiannual observation,

Results and Discussion
Aesthetic feelings are by their nature specific human experiences, caused by the perception of the beautiful and the ugly, of the comic and the tragic in reality. Since the predominant part of human perceptions in the natural environment are visual, in any case, in order to express the positive aesthetic qualities of a certain natural object, visibility to it must first be ensured. This also applies to riparian and coastal landscapes in general, so the first condition for increasing the aesthetics in these landscapes is that they be visible as much as possible. This can be achieved if the principle of maximum proximity of the routes of the coastal alleys to the banks of the watercourse is applied in the planned composition of the alley network (Figure 2). Of course, this is not always possible and depends on the terrain. However, where possible, it is advisable to design coastal alleys as close as possible to the watercourse and to cross it quite often (Figures 2a-2c), at least the secondary alleys However, it should not obscure, but direct the gaze to the water currents and water areas, to focus attention on the beautiful accents in the riparian landscapes.      In all possible cases, when designing the routes of tourist routes, the property of the water to reflect the surrounding plant, architectural or sculptural volumes must be used ( Figure 11).
When including calm water surfaces (lakes, pools, water mirrors, etc.) in the general compositional solution of the nature parks, their favorable influence on the psycho-physical condition of the person and for the rest of the eyes is relied upon.

Conclusion
According to the performed landscape-ecological study carried out on the riparian forest and meadow landscapes, one reaches the various riches of this landscapes, often hidden or devalued due to their improper exposure to tourists. The problematic was: how to design the routes of hiking trails, that these unique landscapes become not only optically visible but also physically accessible to humans. More generally, this will enhance the benefits of human-
