Abstract:
The Lake Fehér near Kardoskút village (Békés County, S Hungary) is a highly protected area of the Körös-Maros National Park. The regular desiccation of the lake violates the habitat of the migrating birds. In order to understand the mechanisms of the water supply of the lake, six groundwater-monitoring wells and two water gauges were made in the area. Data were evaluated by geostatistical methods. Water levels in the two automatically measured monitoring wells changed differently with precipitation. One, which was located in the southern margin of the lake, responded to precipitation immediately and also with a twelve-day delay. While the other one, situated between the lake and the canal, had not any significant reactions. Groundwater flow direction is towards the canal every time, independently of the season. The canal, depending on water level in it, disturbs groundwater flow. Based on pressure-elevation profiles [p(z)], upward flow from deeper layers was established. Chemical data supported upward flow too.
