Abstract

The problem of aquifers and soil salinity is addressed in the coastal area of Muravera (SE Sardinia, Italy) with the combined use of electrical resistivity and induced polarization measurements along three lines, and with 41 Transient Electromagnetic (TEM) soundings distributed in the study area. The resistivity and chargeability sections provide a detailed information on the hydrogeological conditions in the first 20 60 m depth, clarifying the role of both clay and salt water and eventually confirming the local near-surface hydrogeological model. The resistivity maps obtained for different depth ranges by TEM data inversion, give a clear and effective representation of the saline contamination both laterally and down to a depth of about 70 m, over the whole investigated area. The combination of the geophysical techniques (resistivity tomography with Induced Polarization measurements, integrated with TEM soundings) proves very effective as an approach for soil and water salination monitoring.

意大利撒丁岛Muravera沿海含水层和土壤盐度监测的IP和TEM数据综合解释
在意大利撒丁岛东南部的Muravera沿海地区,利用3条线路的电阻率和感应极化测量,以及分布在研究区域的41个瞬变电磁(TEM)测深,解决了含水层和土壤盐度问题。电阻率和电荷率剖面提供了前20 ~ 60 m深度水文地质条件的详细信息,阐明了粘土和盐水的作用,最终确定了当地近地表水文地质模型。通过透射电镜数据反演得到的不同深度范围的电阻率图,清晰有效地反映了整个研究区域的盐污染水平和深度约70 m的情况。地球物理技术的结合(电阻率层析成像与诱导极化测量,结合瞬变电磁法探测)被证明是一种非常有效的土壤和水盐渍化监测方法。
