A new computer algorithm that can "fill in" underground water levels in areas where quality data is not available could lead to improved models of groundwater flow in regions where pumping and aquifer ...

A general mathematical theory that predicts how cracks spread through materials like glass and ice can also predict the direction in which rivers will grow. The group tested the theory on 255 streams ...

Figure 1: The global relationship between porosity, lithology and total groundwater volume with depth. Figure 2: Quantifying modern groundwater from tritium data and numerical groundwater models of ...
