摘要在内盖夫沙漠的山坡上发现了古老的土丘和引水管道。本文介绍了实地和实验室研究的结果，表明古代农民在收集水方面非常有效。将土丘中的石头体积与周围地区的地表石头体积进行比较表明，古代农民只移走了停留在土壤表面的石头，而没有动嵌入其中的石头。根据模拟降雨实验的结果，这种选择性去除增加了一平方米以上的径流量，与自然未经处理的土壤表面相比，对于小降雨事件，增加了近250%。
Abstract Ancient stone mounds and water conduits are found on hillslopes over large areas of the Negev desert. This paper presents results from field and laboratory studies, suggesting that ancient farmers were very efficient in harvesting water. A comparison of the volume of stones in the mounds to the volume of surface stones from the surrounding areas indicates that the ancient farmers removed only stones that had rested on the soil surface and left the embedded stones untouched. According to results of simulated rainfall experiments, this selective removal increased the volume of runoff generated over one square meter by almost 250% for small rainfall events compared to natural untreated soil surfaces.
