Harrastusteaduse kasutamises keskkonna- ja hüdroloogilises seires ei ole maa- ilma mõistes midagi uut. Mitmetes riikides on vabatahtlike seire programmid töös juba aastaid ning nende abil loodud andmekogud on väga väärtuslikud just pikkade aegridade saamiseks. Vabatahtlike abiga keskkonnaandmete kogumine on suhteliselt aja- ja kuluefektiivne, see...

According to the EU WFD, the Member States sharing transboundary GWBs should carry out joint evaluation of the groundwater resources. To ensure this, it is important to establish a representative cross-border groundwater monitoring network. The transboundary area of Estonia (EE) and Latvia (LV) is sparsely populated and features a relatively scarce...

As groundwater does not follow human-drawn boundaries such as country borders, groundwater pollution in one country can adversely affect groundwater quality and availability in a neighboring country. It is vital to develop a conceptual understanding of shared groundwater resources not only to ensure their protection but also to avoid future conflic...

A pilot study was carried out in the Matsi spring fen, southern Estonia to test a proposed methodology (Terasmaa et al., 2020) for identifying potential effects of groundwater bodies on groundwater dependent terrestrial ecosystems (GDTE). A comprehensive hydrochemical and isotopic dataset was collected and analyzed using multivariate statistical me...

Joint methodology for identification and assessment of GDTEs was developed to identify GDTEs in trans-boundary Gauja-Koiva river basin (funded by Interreg EstLat project “GroundEco”). The methodology and best GDTEs assessment techniques were tested in two pilot areas – Matsi spring fen in Estonia and Kazu leja valley in Latvia. Finally, recommendat...

This research is carried out in the framework of the project "Joint management of groundwater dependent ecosystems in transboundary Gauja-Koiva river basin" (GroundEco, Est-Lat62) funded by ERDF Interreg Estonia-Latvia cooperation programme. The main aim of GroundEco is to develop a common understanding and joint methodology for the Estonian and La...

Groundwater dependent ecosystems (GDEs) are valuable ecosystems that depend on groundwater input and cannot be considered and assessed separately. Dynamic interactions at the surface-groundwater interface are widely recognized, but the role of groundwater in terrestrial ecosystems is not well documented. Any changes in the water supply or chemical...
