EFFECT OF RIVER SAALE ON GROUNDWATER HYDROCHEMISTRY OF THE JENA BIODIVERSITY EXPERIMENTAL FIELD: A HYDROGEOCHEMICAL MODELING APPROACH
Abstract
The effect of biodiversity on ecosystem func tion is complex and requires understanding of all interacting systems, such as hydr ology, geology and above ground plant diversity of the study area. In this study hydrogeoch emical modeling using PHREEQC was used to investigate the effect external fact ors (nearby river Saale and an underground channel) on the groundwater chemistry of a large grassland diversity experiment (Jena experiment). Groundwater chemical analys is was performed for river Saale and groundwater wells which are far from the rive r (least affected by river) and from wells which are near to the river (suspected to be affected by the river). We also measured piezometric heads from 12 groundwater wells and used to delineate groundwater flow direction. The result shows th at there is no significant effect of river Saale on the groundwater chemistry of the study area at mean river flow. However, Fe, K, Ca, Cl, Mg, Mn, SO 4 2- and NO- 3 concentrations of the groundwater increased significantly when the inflow of the river increases toward the groundwater of the study area. Chloride concentration (used as hydrologic tracer) measur ed at the inlet of the channel and in groundwater shows that the channel did not leak and therefore has no effect on the groundwater.
