Soils from a lowland small sub-catchment of the Tisza river have been analysed for phosphorus adsorption characteristics in Hungary. Five genetic soil class have been determined based on national soil databases and 21 soil samples have been collected and analysed, 3-5 samples per class. The aim of the study was to create isotherms for the soil samp...

Novel soil datasets and the application of pedotransfer functions provide soil hydraulic input data for modelling hydrological processes at different scales. We aimed to evaluate the reliability of soil hydraulic parameters derived by indirect methods in simulation of soil moisture time series and water budgets at profile level of three sites (Fore...

Effluents of municipal wastewater treatment plants (WWTPs) contribute to surface water pollution, especially when large plants discharge into rivers with smaller flow values. Recognizing this, the EU has launched the Urban Wastewater Treatment Directive (UWWTD), aiming at protecting valuable freshwater resources. After achieving much success, but n...

Purpose According to standard procedure recommended by the Water Framework Directive (WFD), dissolved concentrations of potentially toxic elements (PTEs) in river water are determined by inductively coupled plasma mass spectrometry (ICP-MS) in filtered (0.45 µm) and acidified (pH 2) samples. Properly prepared and stored composite samples can enhanc...

Trace substances represent one of the central challenges for water management in the Danube River Basin. This article presents the concept and an overview of the results of the project Danube Hazard m3c, which was carried out within the framework of the Interreg Danube Transnational Programme of the EU from 2020 to 2023. In the course of the projec...

There is a growing awareness of the fact that chemicals of everyday usage usually end up in the environment resulting in degraded functioning of the ecosystems. In a one-year sampling campaign conducted in four medium sized catchments of the Carpathian Basin: Wulka, Austria (389 km²), Koppány, Hungary (660 km²), Zagyva, Hungary (1200 km²) and Somes...

Szerves és szervetlen anyagok sok évtizede kerülnek a környezetbe; sorsuk és viselkedésük iránt azonban főleg az utóbbi években nőtt meg az érdeklődés, miután fény derült rá, hogy-a környezetbe kikerülve sokuk perzisztens, bioakkumulációra hajlamos és már egész kis koncentrációban is toxikus. Környezeti mintákból való kimutatásuk-részben az alacson...

This document aims to establish a common understanding on the role of sediment in achieving the objectives of the Water Framework Directive, and to provide guidance on how to address pressures on sediment quantity and sediment contamination, in the context of the River Basin Management Plans, and also other policies’ planning instruments. It covers...

The pursuit of good management of our waters poses permanent challenges to the whole society. Decision-makers often need to define appropriate and sustainable strategies on interdisciplinary topics, like water management issues. The rapidly evolving quantification and mapping of hydrologic ecosystem services (HES) is putting hydrologic and water ma...

Organic and inorganic substances have been emitted into the environment for many decades; however, the interest in their fate and behavior has grown mainly in recent years. Due partly to the meager amount they are present in environmental compartments such as rainwater, river water, or waste waters, substantial resources are needed to detect their...

Riverine floods cause increasingly severe damages to human settlements and infrastructure. Ecosystems have a natural capacity to decrease both severity and frequency of floods. Natural flood regulation processes along freshwaters can be attributed to two different mechanisms: flood prevention that takes place in the whole catchment and flood mitiga...

During the 20th century in the Hungarian lowlands the emphasis was put on maximizing provisioning ecosystem services (ES), which caused the weakening of regulating and other services. With the growing environmental pressures, it is crucial to apply a more adaptive landscape management. This, however, leads to territorial conflicts, as large areas w...

The contamination of waters with nutrients, especially nitrogen and phosphorus originating from various diffuse and point sources, has become a worldwide issue in recent decades. Due to the complexity of the processes involved, watershed models are gaining an increasing role in their analysis. The goal set by the EU Water Framework Directive (to re...

In many years excess water inundations generate a major obstacle to farming in the lowland part of Hungary, including the Marosszög area. Diverting water to large distances requires an infrastructure that is costly to develop and maintain. Alternatively, low-lying local land segments could be withdrawn from cultivation and utilized to collect the s...

A country scale analysis of diffuse source nutrient emissions have been undertaken previously on small catchments level using the MONERIS model, which needed a proper estimation of surface and subsurface runoff differentiation to support or contradict its own water budget based method. As reliable, country scale base flow estimation has not been av...

An integrated hydrological model has been applied for small rural-urban catchments at the Tisza-Maros confluence using the WateRisk integrated hydrological model system. The aim of the hydrological simulations was to identify the role that the relief plays in the runoff generation process, and to highlight the relationship between the precipitation...

There is general agreement among scientists that global temperatures are rising and will continue to increase in the future. It is also agreed that human activities are the most important causes of these climatic variations, and that water resources are already suffering and will continue to be greatly impaired as a consequence of these changes. In...

Efficient solutions to flood and water logging problems are hardly achievable without flexibility in land use and management. This report considers how the use of economic policy instruments (EPIs) can improve the flexibility of land use and thereby contribute to more cost-effective flood protection and offer solutions to water logging problems. Tw...

An integrated hydrological model has been developed for a small rural-urban catchment of Tisza-Maros-szög geographic area. The work has been done within the framework of the EPI-WATER FP7 EU project and the aim of the model was to support the research of the applicability of economical instruments into landscape and water management decisions. The...

An integrated hydrological model has been applied for a rural-urban catchment of the Szamos-Kraszna interfluve geographic area, using the WateRisk integrated hydrological model system. The aim of the hydrological simulations was to identify the role that the relief plays in the water coverage formation process, and to highlight the possible consequ...

Application of WateRisk Integrated Hydrologic Model (WR IHM) on two pilot areas (PA) is introduced. Inland excess water (quite similar hydrological conditions to wetlands) and drought have been primarily focused on. The developed WR IHM proved to be able to describe complex hydrologic-hydrodynamic processes simultaneously by coupled surface-subsurf...

There are major unsolved water resources problems (water scarcity, excess water, floods, water budget imbalance) in Hungary, which are likely to worsen in the future due to the unfavourable trend of driving forces. The aim of the WateRisk project was to support scientific understanding and management of the mentioned issues. To do so, a novel scena...

A Kárpát-medence, s így hazánk vízkészleteinek jövőjét különböző külső és belső környezeti, társadalmi, politikai folyamatok kombinációja határozza meg – mint például a globális változások (beleértve az éghajlatváltozást), a népességnövekedés, a földhasználat-változás, a terület- ill. településfejlesztés, ill. a gazdasági és technikai fejlesztések....

A WateRisk egy jelenleg fejlesztés alatt álló integrált dinamikusan kapcsolt modellrendszer, mely komplex vízkészletgazdálkodási problémák vizsgálatát hivatott ellátni. A dolgozat ennek egydimenziós nempermanens, nyílt felszínű és nyomás alatti vízmozgás számolására alkalmas numerikus almodelljét mutatja be. A modell hibaelemzése céljából egy teszt...
