The objective of this proposal is to develop a technique capable of identifying, locating and quantifying leakages through liners or barriers that contain hazardous leachates. The technique is based on the use of seismic boundary waves. These waves propagate along soil/water and soil/soil boundary created by a liner or barrier. These boundary waves are focused on the liner interface and are highly sensitive to the conditions of this interface. Changes in moisture, void ratio and permeability can be detected and correlated to leakage events. On Phase I the feasibility of this concept was demonstrated by conducting a small scale field test. The objective of Phase II is to: confirm the concept, integrate the hardware, develop the analysis and interpretive software, develop implementation methods and interpretive techniques.

这项提案的目的是开发一种技术， 能够识别、定位和量化泄漏 通过含有有害沥滤物的衬垫或屏障。 该技术是基于地震边界波的使用。 这些波沿沿着土/水和土/土边界传播 由衬垫或屏障形成。 这些边界波是 集中在内衬界面上，并且对 这个接口的条件。 水分、孔隙比的变化 并且渗透率可以被检测到并与泄漏相关联 事件 在第一阶段，这一概念的可行性是 通过进行小规模的现场测试来证明。 的 第二阶段的目标是：确认概念，整合 硬件，开发分析和解释软件， 开发执行方法和解释技术。
