Conducting complex hydrologic evaluations

M&A conducts surface water monitoring to evaluate the distinction between surface water, subflow, and groundwater and has supported Arizona’s stream adjudication proceedings since the 1980s. We characterize the complex hydrologic interactions between groundwater and surface water using specialized modeling, data analysis, and monitoring tools.


  • Streamflow monitoring and impact analysis
  • Springs and seeps characterization of baseline conditions
  • Waters of the United States (WOTUS) stream evaluations
