Groundwater is an essential resource throughout Nebraska. Land use and climate change can impact groundwater quality and quantity, both of which are necessary for sustaining agriculture, industry, and human consumption. A better understanding of various factors that influence groundwater movement and contamination will assist water managers in making management decisions. However, since groundwater is not as easily visualized as surface water, it can be difficult and costly to create a complete picture of the subsurface environment and different factors impacting groundwater quality and quantity. This dissertation focuses on groundwater seasonality (when groundwater infiltrates below the root zone), a novel remote sensing approach for assessing groundwater quality, and a case study looking at groundwater recharge and nitrate movement around a groundwater mound and how these different methods can come together to form a more cohesive understanding of the subsurface to assist groundwater managers in decision making.
