Mathematical model of the groundwater system in this area includes 13 types of data and spans multiple aquifers over more than a century. This enables us to assess the quantity of groundwater, where and how it is being used, and how pumping affects it.
Airborne electromagnetic surveying is used to estimate the character of the permafrost by measuring and monitoring the electrical resistivity, which is affected by lithology, temperature, water, and ice.
The report describes a strategy for monitoring, modeling, and research activities to support management decisions to improve water-quality conditions in the Mississippi River Basin, reduce hypoxia in the northern Gulf of Mexico, and improve conditions for
