Application of over-winter green cover (e.g. cover crops) as a measure for reducing nitrate losses from tillage land has been frequently investigated, especially in the unsaturated zone. Monitoring of groundwater is less common in these studies. Studies on groundwater responses to different land treatments can be challenging because they can be influenced by various conditions, such as recharge...

This report concerns a study which was conducted for SKB. The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the client. Abstract This report presents the current state of ecological knowledge and applied research relating to groundwater. A conceptual picture is given of groundwater fauna occurrence in regard to Swedish ...

Heavy seismic damage tends to occur in slopes when groundwater is present. The main objectives of this paper are to determine the dynamic response and failure mode of sandy slope subjected simultaneously to seismic forces and variable groundwater conditions. This paper applies the finite element method, which is a fast and efficient design tool in modern engineering analysis, to evaluate dynami...

This paper describes how climate influences the hydrology of an ephemeral depressional wetland. Surface water and groundwater elevation data were collected for 7 years in a Coastal Plain watershed in South Carolina USA containing depressional wetlands, known as Carolina bays. Rainfall and temperature data were compared with water-table well and piezometer data in and around one wetland. Using t...

In addition to geological, hydrological and hydrogeological invcstigations and $roundwater tracing, detailed surveyin of the groundwater quality IS becoming particular1 important for environmental impact monitoring on karst aquifers. &roundwater qualitydata contain NO types of information, i.e. the natural chemistry of water and its caused by anthropognicimpacts. The method of results presentat...

Utilization of wastes from livestock complexes for irrigation involves the danger of groundwater pollution by nitrates. In order to prevent and minimize pollution, it is necessary to apply geological-hydrogeological evidence and concepts to the situation of wastewater irrigation for the purposes of studying natural groundwater protectiveness and predicting changes in groundwater quality as a re...

Over-exploitation of coastal aquifers causes seawater intrusion and eventually contamination of groundwater wells in many parts of the world. Artificial recharge of treated wastewater can be used to avoid or control seawater intrusion. A common characteristic of many coastal areas in Southern Europe is that most of the annual water demand, and hence the amount of water that can be used for arti...

Management Act (SGMA) in California obligates increased levels of management in highand medium-priority groundwater basins in the near future in order to achieve long-term sustainable groundwater conditions (DWR 2014). An immediate challenge for effective management in many agricultural areas reliant upon groundwater is that little or no information currently exists on the amount of water extra...

Groundwater microbial community samples are traditionally collected using pumping techniques optimized for groundwater chemistry assessment although the impact of groundwater pumping parameters on apparent bacterial community structures (BCS) is not really known. We therefore studied the impact of pumping lift, flow regime and tubing material on BCS, which were analyzed by terminal-restriction ...
