Riparian zone hydrological rehabilitation along the Gyöngyös stream (Hungary)
<p>Climate change induced drought periods are likely to cause decline in groundwater level,<br>which can degrade riparian ecosystems (such as riparian forest). With a reasonable water<br>supply, water scarcity can be stopped and these valuable ecosystems can be preserved.</p><p>The aim of the research was to evaluate the impact of water supply interventions regarding<br>habitat reconstruction of Doroszl&#243; meadows near K&#337;szeg (west Hungary). Groundwater<br>monitoring wells have been installed at 4 representative sites of the area. Groundwater wells<br>were 3&#8211;5 m deep and screened at their bottoms (2&#8211;4 m). The water level of the wells was<br>recorded manually, on a weekly basis, with an accuracy of 1 mm. In the neighborhood of the<br>wells surface close soil moisture values were also measured. Data from April 2019 to<br>October 2020 were collected. Local meteorological data measured in K&#337;szeg were also<br>used for analysis.</p><p>Evaluating the data from each well in the pre-intervention period (the analysis of the<br>relationship of the wells with the control well), we came to the conclusion that the Well-1 and<br>Well-2 behave similarly. The impacts of the water supply on the groundwater level were<br>analysed using a &#8220;double mass curve&#8221; and a &#8220;treatment-control space-time deviations&#8221;<br>approach. Result showed that the intervention had a positive effect only on the Well-3 from<br>the examined wells. The data evaluation denoted that unfortunately the control well was also<br>affected by water supply interventions.</p><p>This research has been supported by the Ministry of Agriculture in Hungary.</p>
