开发利用地下水,是保证遇旱有水、改旱地为水地、促进农业生产的有效措施。在开发地下水的实践中,山区群众总结出许多找水的经验。现介绍几条,仅供参考: (一)“丘陵地上季节河,打井宜在迥水窝。”意思是说,在季节性沙河上,应在河流拐弯处找水。因为拐弯处地表水流总是顺凹岸流动,当河岸有良好的透水层时,易渗入地下补给地下水。所以,群众常在河流弯道凹岸的下游打井。 (二)“大山前,好挖泉”。山区由于降雨集中,地势陡峻,山洪挟带大量的碎石、砾石、风化土,在冲出沟口时,水
Exploitation and utilization of groundwater is an effective measure to ensure that water and land are converted into dry land and promoted agricultural production. In the practice of developing groundwater, the mountainous people summed up many experiences of finding water. Is now introduced a few, for reference purposes only: (A) “The seasonal seasonal river in the hilly, wells should be in the Joushuwo.” Mean, in the seasonal Shahe, water should be found at the corner of the river. Because the surface water at the bend always flows along the bank, when the bank has a good water-permeable layer, it is easy to infiltrate the ground to supply groundwater. Therefore, the masses often dig wells downstream of the river bend. (B) “before the mountain, a good dig Quan.” Due to the concentrated rainfall in the mountainous area, the terrain is steep, the mountain torrent carries a large amount of gravel, gravel, and weathered soil. When rushing out of the Mizoguchi, the water
