Sensors for landmine detection are often affected by soil water content, temperature, electrical conductivity, and/or dielectric constant. The most important of these is water content because it influences the three other properties directly. Using HYDRUS-2D, we modeled water distributions around antitank mines buried in six soil textures varying from sandy loam to clay loam under the climatic conditions of Bosnia and Kuwait. The modeling results demonstrate that soil water content regimes around landmines are strongly affected by the interaction between climate, soil type, and landmine geometry. The occasional short-term accumulation or loss of soil water around landmines depends greatly on weather conditions and soil types. Results also show that steady-state analysis of water flow around buried objects and time averaging of observed water contents may lead to unrealistic conclusions regarding the transient behavior of soil water distributions around land-mines.
