Sažetak
Saltwater intrusion in coastal aquifers has been widely investigated in last few decades primarily due to the negative effects to the agricultural yield in coastal areas. To mitigate salt-water intrusion, traditional surveys like geo-electric and/or seismic reflection/refraction are often used with a goal to identify necessary aquifer characteristics. Compared to abovementioned techniques, which can be financially high demanding, tidal methods are shown to be successful and effective for determination of coastal aquifer parameters in many coastal areas around the world (Zhou et al. 2006 ; Xia et al. 2007 ; Zhou 2008). Although the hydrogeological site characterization procedure of river Neretva valley started in 1960s, no completely clear picture has been conducted up to date. To handle the problem of the saltwater intrusion and piezometric state dynamics, a monitoring system has been established during last 10 years within the area. In this paper we take into consideration: i) available “soft” aquifer data: borehole information and slug test results, and ii) observed data of long- term sea level oscillations and piezometric head observed in a borehole positioned 85 m away from the coastline towards inland, to determine river Neretva Valley aquifer parameters, respectively: hydraulic diffusivity, storativity and transmissivity. To our best knowledge, this is the first paper dealing with determination of Neretva aquifer parameters determination although the area is of great agricultural importance.
