Now is the time to take our future more seriously and start providing solutions for tomorrow´s world. The new notion or significant specification of the term “BLUE to GREEN” infrastructures in buildings in the modern information age is the expression of the sustainable development of a „smart city“ society and beyond. We introduce our experimental platforms representing different types of green roofs, green and water walls as possible solutions. These experimental sites in the University Campus were created on the basis of researche dealing with green roofs and their retention qualities, as well as green walls and their impact on the microclimate and the possibility of using rain and gray water that could be filtrated through the media of these structures. The paper describes the world-wide conditions on the basis of which this issue is up to date and addressed. The outputs from the individual measurements will be related to water cycle issues, green walls and roofs constructions.

Monitoring of river's water status in Kujavianand Pomeranian Voivodeship is carried out in the three programs: surveillance monitoring, operational monitoring and monitoring of protected areas. Surveillance monitoring is a main instrument to determine the classification of the status of water bodies,accordance with the requirements of the Water Framework Directive. Operational monitoring has a task of monitoring bodies at risk of failing to achieve environmental objectives. Monitoring on protected areas is carried out on areas exposed to pollution from municipal sources and nitrogen from agricultural sources, the areas of protection of species and habitats, water for public supply of drinking water and water for bathing purposes. This three types give an answer about classification of the status of water bodies –main purpose of Water Framework Directive. The last 6-years monitoring programme is finishing in 2015 and Inspectorate for Environmental Protection on territory of Poland must prepare new network of river’s bodies of surface waters. Kujavian and Pomeranian Voivodeship Inspectorate for Environmental Protection prepared new monitoring network, which have 39 research profiles in surveillance monitoring, and 96 research profiles including operational and protected areas monitoring.

Zmiany klimatu są faktem, który ma swoje odzwierciedlenie również w regionie Morza Bałtyckiego. Niedobory wody pojawiają się coraz częściej, powodując problemy techniczne oraz pojawienie się konkurencji o wodę pomiędzy przemysłem, rolnictwem i usługami komunalnymi.

In the present study, an attempt has been made through a hydrological model (SWAT – Soil and Water Assessment Tool) to simulate water cycle components over the Narmada river basin, one of the largest rivers in the Indian peninsula. The model was forced with observed as well as CFSR rainfall data to calibrate surface runoff simulated by the model. The spatial and temporal variability of the water cycle components were examined by running the SWAT model for 30 years (1984-2013) at a daily time-scale using CFSR precipitation, temperature, humidity, winds and solar radiation. It was found that there are large variations in hydrological parameters simulated by the model from sub-basin to sub-basin and year to year. During the monsoon seasons, surface runoff is maximum but during other seasons, almost no surface runoff is seen as there is almost no rain. Groundwater increase is seen after about 1 month of rainfall peaks in the basin. Evapotranspiration has two peaks, one in March-April and the other in August. Much less evaporation takes place in the basin in the month of May. These components (other than surface runoff) are also sensitive to climatic forcing (winds, relative humidity and solar radiation in addition to temperature and rainfall) applied. Evapotranspiration increases when all the climatic parameters are used, which then reduces the water availability on the surface for percolation and groundwater recharge. However, rainfall is the key parameter which decides the hydrology in the Narmada basin. The SWAT model has been able to compute water balance at basin and sub-basin scales.

Zawartość poszczególnych form azotu mineralnego w obiegu hydrologicznym zlewni Wieprza była zróżnicowana w zależności od fazy obiegu wody. Dominującą formę występowania w cyklu hydrologicznym stanowił jon azotanowy(V). W opadach atmosferycznych, spływie powierzchniowym i wodach aluwialnych wysoki udział wykazywał także jon amonowy. Azotany(III) miały niewielki udział w migracji azotu na poszczególnych etapach obiegu hydrologicznego wody.

EN

The content of particular forms of mineral nitrogen in the hydrological cycle of Wieprz river catchment was diversified depending on the phase of water circulation. Nitrate ion was a dominant form of appearance in the hydrological cycle. High share of ammonium ion was also observed in precipitation, surface runoff and alluvial waters. Nitrites showed rather limited share in nitrogen migration on particular stages of the hydrological cycle of water.
