This technique is applicable in sandy riverbeds that are seasonally dry but experiences high siltation during water runoffs. Sites with high riverbanks and lower slopes are also desirable. The geology in the location the dam is to be placed has to be considered as well. It is good when there is an impermeable surface or a less permeable surface below the river channel. This will prevent the water from seeping under the dam too much and it gives something that the dam can be placed upon for stability.
