This activity will require approximately fifty minutes. Groundwater recharge occurs from precipitation, snow melt, or surface water in streams, lakes, and wetlands. Groundwater may also be recharged from human irrigation or sprinkling systems including water canals, ditches, and reservoirs. Recharge will vary as to the wet time of year depending on precipitation, soil type, vegetation, and land utilization.
Augmentation is the recharge of groundwater by the user.
It is frequently a replacement system of water purchased, leased, or pumped from wells. In some instances, the water may be augmented from waste water systems or excess runoff in drainage systems. The purpose of this activity is to provide the learner practical experience in groundwater recharge and groundwater augmentation through the use of a constructed model. 2. construct and observe groundwater movement and changes as a result of using variables. 3. investigate and discuss a variety of processes for groundwater recharge.
