Alluvial groundwater definition

Alluvial groundwater means water located below the land surface within the Quaternary hydrostratigraphic unit that borders or underlies major perennial and intermittent streams in the Tongue River and Rosebud Creek basins. This unit is composed of unconsolidated alluvial deposits of clay, silt, sand, and gravel. For the purposes of this Compact, all other water below the land surface will be deemed nonalluvial groundwater.

Examples of Alluvial groundwater in a sentence

  • Alluvial groundwater may discharge to Blacktail Creek (BTC) and Silver Bow Creek (SBC); therefore, groundwater capture and treatment systems are in place to minimize discharge of contaminated groundwater to BTC and SBC and prevent exceedances of surface water ARARs. This requires development of a groundwater monitoring plan that will ensure data is of adequate quality and is usable to assure the groundwater capture systems are operating effectively and preventing surface water standard exceedances.

  • Alluvial groundwater levels depend on seasonal precipitation and runoff, and on basin-scale hydrogeology including connections between the alluvial aquifer and surrounding basin-fill and bedrock aquifers.

  • Alluvial groundwater is mainly regener- ated by the infiltration of river water and hill slope groundwater.

  • Alluvial groundwater quality in Mortandad Canyon has improved due to these project improvements.
