Description

Sand dams, a popular water harvesting structure employed by rural communities, capture and store water for use during the dry season in arid and semi-arid regions. This dataset was produced during a year-long, in-depth field study of three sand dams in Tanzania. The study investigated a sand dam’s impact on vegetation, streambank erosion, and the local water table. Vegetation surveys were performed every other month, and erosion was recorded semi-monthly. Water table monitoring wells were installed at each sand dam, and measurements were taken twice a day. The functioning sand dams, Chididimo and Soweto, store a significant amount of water, but most is lost to evapotranspiration shortly after the dry season begins. The functioning sand dams have a positive impact on local vegetation and minimal impact on erosion. Kimokouwa sand dam is essentially non-functioning. Erosion and water table measurements were taken and recorded by trained community volunteers.
