<abstract xmlns="http://www.w3.org/1999/xhtml">Greenery of cemeteries creates a substantial part of the public greenery in our towns but often does not subserve greenery functions. The older architectonical burial places where the greenery is diminished on tree-lined communications by reason of spatial limitation represent the most widespread cemetery type of Slovak towns. Existence of woody plants at these conditions is affected by various negative factors which result in vitality decreasing and poor aesthetic standard of woody plants in burial places. The article is focused on evaluation of greenery in the two eldest cemeteries in Nitra town. The obtained data describe complex dendrological analysis, species composition, landscape value and health assessment of woody plants. On base of evaluation results we have proposed the principles of framework methodology for greenery restoration and maintenance management of woody plants in sepulchral places.</abstract>

Some Aspects Of Greenery Restoration And Maintenance Management Of Woody Plants In Cemeteries In Nitra, Slovakia

<abstract xmlns="http://www.w3.org/1999/xhtml">The contemporary Urban Agriculture (UA) is represented by a range of diverse farming typologies taking place in the urban environment. Nowadays, there is an unconventional form of UA called squat farming. The research object of this paper is represented by the case study of Can Masdeu which stands for a squatted and cultivated land at the northern city border of Barcelona. The goal of our Short Term Scientific Mission carried out in the Barcelona Metropolitan Region was to define and study diverse typologies of UA at different levels and scales. One of these types is represented by the ongoing phenomenon of squat farming. Concerning this form, there are two main research questions: 1) How are landscape and urban structures influenced and formed by the activity of land cultivation? and 2) How is the social dimension of squat farming structured – who are the users, what is their motivation, aim and vision? To answer the first research question, we applied spatial and perceptual analyses, and concerning the second research question, the users have been interviewed within discussions and questionnaires. The results include characteristics of spatial and social dimensions of squat farming described on the case study of Can Masdeu.</abstract>

Landscape As A Resource For Squat Farming

<abstract xmlns="http://www.w3.org/1999/xhtml">The Water Framework Directive (WFD) is a key initiative aimed at improving water quality throughout the EU. The development of the computer technologies enables us to solve the ecological problems in water management practice very efficiently. The mathematical and numerical modelling allows evaluating various situations of contaminants spread in rivers (from everyday wastewater disposal through the fatal discharges of toxic substances) without immediate destructive impact on the environment. The paper deals with 1-dimensional numerical model HEC-RAS and its response on various values of dispersion coefficient. This parameter is one of the most important input data for simulation of pollution spread in streams. There were performed tracer experiments in the Malá Nitra River and results of these measurements are compared with results of numerical simulations. The values of the longitudinal dispersion coefficient were estimated from this comparison. The range of mean values of this coefficient determined on the base of numerical model application was 0.05 – 0.13 m2 s−1, for the other flow condition it was 0.07 – 2.5 m2 s−1 or 0.28 – 0.6 m2 s−1. The next task was carrying out the model sensitivity analysis, which means to evaluate input data influences, especially longitudinal dispersion coefficient, on outputs computed by 1-dimensional simulation model HEC-RAS. According to the results it can be said that the model HEC-RAS responds to longitudinal dispersion coefficient value changes adequately, suitably and proportionately. The application of the model HEC-RAS demonstrated the eligibility for simulation of pollution spread in streams, which means that it is a suitable tool allowing a reasonable support in decision making process connected to river water quality management.</abstract>

Pollution Spread Analysis In The Malá Nitra River By Using Of 1-D Model

<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of the study was to determine the influence of coal mine waters on water quality in the Vistula River. Water samples for laboratory analysis were collected in 2011 and 2012 on one kilometer long section of the river. Basic parameters were measured at the collection spot. The study asseses the dynamics of physicochemical water properties, fulfillment of the quality requirements necessary to introduce contaminated water into the river, water salinity, quality, and utility values. The study indicates that water quality of the Vistula River has been rapidly decreasing as a result of coal mine water introduction. Water becomes degraded, unfavourable for fish communities and unsuitable for use by people. Coal mine water contamination exceeds allowable pollution levels stated by legal regulations. Self-purification of the river is efficient as contamination levels decrease at the length of the examined section of the river.</abstract>

The Effect Of Saline Mine Waters Discharge From Hard Coal Mine On The Ecological State Of The Vistula River

<abstract xmlns="http://www.w3.org/1999/xhtml">Rye Island is a unique natural formation, which lies between the main flow of the Danube River and the Little Danube River and is the largest river island in Europe. It is located in the southwest of Slovakia and with its mild to slightly warm climate is one of the most fertile agricultural areas in Slovakia. The whole Rye Island is also our greatest reservoir of quality waters used for drinking purposes, where groundwaters of Rye Island are permanently supplied with water from the Danube River. It means that as water levels in the Danube River were unstable before the construction of the Gabčíkovo Water Project, also the groundwater level faced large fluctuations. Changes occurred after putting the Gabčíkovo Water Project into service, with a decrease in groundwater levels. Thereby, the conditions for agriculture have improved and drying of surrounding protected floodplain forests has stopped. Through the present contribution we decided to analyse the impact of Gabčíkovo on soil water regime in the area of Rye Island, and evaluate the course of groundwater level, precipitation and soil water storage over time. For the representative area we chose a forest ecosystem of Král’ovská Lúka and evaluated the period 1999 to 2009.</abstract>

Diagnosis Of The Impact Of The Gabčíkovo Water Project On Soil Water Regime In The Surroundings

<abstract xmlns="http://www.w3.org/1999/xhtml">Spatial data have become very important phenomena within the last decade in Europe due to a strong support from the political spectrum with regard to related legislation and resulting in financial support to several research, educational, and enlargement projects. INSPIRE (Infrastructure for Spatial Information in the European Community) Directive indeed defines the principles for the harmonization of spatial data infrastructure in the European community, including Land Use and Land Cover data themes. INSPIRE defines a methodology on how to transform datasets to common data models, but it does not cover the process of data collection and update, because it is out of its scope. Evaluation of the Land Use dataset derived from remote sensing products complemented by fieldworks has been realized since 2006 by Eurostat within the LUCAS (Land Use and Cover Area frame Survey) project. The work presented in this paper follows the LUCAS fieldwork methodology, which was applied during the fieldwork in July 2014 in the City of Zagreb (Croatia), to use at the local (municipal) geoportal level. The surveying groups collected point features with the following data type attributes: Land Use codes defined by HILUCS (Hierarchical INSPIRE Land Use Classification System) and optional Land Cover codes defined by LUCAS classification. In addition, photographs representing the observed areas were collected by cameras embedded in the mobile GIS platforms. An update of original topological layer was performed and Web GIS components for sharing the newly developed datasets were implemented. The results presented provide a suitable proposal for fieldworks methodology and updates of a land use database in line with the INSPIRE directive applicable at a local spatial data infrastructure level.</abstract>
