The aim of the work was establishment of research green roofs on Mendel University in Brno. The experimental green roofs were established in August 2015 and it is based on current issues of rainwater management and the quality of storm water launched into recipients or sewage system. There is a valid legislation addressing the management of rainwater in environment – decree no. 268/2009, Coll., and decree no. 269/2009, Coll. Four experimental plots were created and placed in Mendel University Campus. It was hypothesized that different types of experimental plots will result in different amount of retained water and in different quality of water runoff. Resulting hypotheses proved statistically significant difference between the height of rainfall and runoff height on individual types of green roofs. In addition, it was shown that the different types of roofs prove statistically significant difference in the ability to reduce runoff (retention efficiency).

The increasing urbanization process in Europe has resulted in an increase in the proportion of impervious areas in the development of watersheds. This fact, combined with the more frequent occurrence of volatile rainfall, contributes to the formation of high intensity surface runoff, which results in local flooding of the lowest located areas. Water runoff also causes a large amount of pollution from the catchment to be flushed away and transported to the receiver, which generates many negative effects on the environment. Due to these unfavorable changes in the urban catchment, it is necessary to manage the waters in accordance with the principles of sustainable development. One of the basic tools to protect the quantity and quality of water discharged from the catchment area is to take into account the need to implement technical solutions to increase the retention of rainwater in cities. Such solutions, consisting of designing natural rainwater management systems, could work independently or in cooperation with traditional rainwater drainage systems [1].

Wastewater discharge into rivers has a negative impact on the quality of water resources. The existing methods for assessing the anthropogenic load from the discharge of wastewater into rivers do not allow one to compare and rank according to the degree of load rivers that differ in the size of the catchment area and are located in different natural zones. The author has developed a method for assessing and analyzing the anthropogenic load on rivers from the discharge of pollutants, which takes into account the water content of rivers and basin features of the formation of the quality of water resources. The proposed method makes it possible to determine the integral and differentiated loads for priority pollutants. It allows you to decompose the load into separate components (nitrogen, phosphoric, sulfate, chloride, etc.), to standardize the load taking into account the quality of river waters and to assess the priority of specific pollutants. This method has been tested on 12 rivers in Russia located in different natural and climatic conditions and having a wide range of water runoff values from 10 to 600 km3 / year. The calculation results showed that p. The Volga is experiencing the greatest anthropogenic load from the discharge of pollutants in wastewater. Therefore, first of all for the river. On the Volga, it is necessary to develop a basin program for the gradual reduction of anthropogenic load and mechanisms for its implementation

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.

Urban development, agricultural runoff and industrialization have contributed pollution loading on the environment.  In this study Hemavathi river water from a stretch from its origin point to its sangama was studied for pollution load by determining parameters of water quality like pH, Alkalinity,  Ca, Mg, Nitrate, TDS, BOD, COD , and the results were compared with WHO and BIS standards to draw final conclusion on the quality of water.

In this paper, the linear regression model using ANN and the linear regression model using MS Excel were developed to estimate the physico-chemical concentrations in groundwater using pH, EC, TDS, TH, HCO3 as input parameters and Ca, Mg and K as output parameters. A comparison was made which indicated that ANN model had the better ability to estimate the physic-chemical concentrations in groundwater. An analytical survey along with simulation based tests for finding the climatic change and its effect on agriculture and water bodies in Angul-Talcher area is done. The various seasonal parameters such as pH, BOD, COD, TDS,TSS along with heavy elements like Pb, Cd, Zn, Cu, Fe, Mn concentration in water resources has been analyzed. For past 30 years rainfall data has been analyzed and water quality index values has been studied to find normal and abnormal quality of water resources and matlab based simulation has been done for performance analysis. All results has been analyzed and it is found that the condition is stable.

The hydro geochemical features of Neyyar River for a period of one year from May 2015 to April 2016 were analyzed. Six sampling sites were fixed considering physiography and present landuse pattern of the river basin. The residents in the drainage basin are primarily responsible for framing a better landuse and thereby maintain a good water and sediment regime. Geospatial pattern of the present landuse of the study area indicated that the sustainability of this river ecosystem is in danger due to unscientific landuse practices, which is reflected in the river quality as well. The parameters such as hydrogen ion concentration, electrical conductivity, chloride, Biological Oxygen Demand, total hardness and sulphate of river water and Organic Carbon of river bed sediments were analyzed in this study. The overall analysis shows that the highland areas are characterized by better quality of water together with low organic carbon, which is mainly due to better landuse and minimal reclamation. The midland and lowland areas are characterized by poor quality of water with high organic carbon, which is due to high anthropogenic activities and maximum pollutants associated with the region together with the alteration in landuse from a traditional eco-friendly pattern to a severely polluted current pattern.
