The scientist’s investigation covers issues in Hydrology, Water resources, Surface runoff, Streamflow and Evapotranspiration. His work carried out in the field of Hydrology brings together such families of science as Ephemeral key and Precipitation. His studies in Water resources integrate themes in fields like Global warming, Climate change, La Niña, Spatial ecology and Stream flow. His Climate change study incorporates themes from Drainage basin and Climatology. His research in Surface runoff intersects with topics in Infiltration and Baseflow. Neil R. Viney interconnects Cross-correlation, Truncated mean and Mesoscale meteorology in the investigation of issues within Streamflow.
