Capture Zone Analytic Element Model (CZAEM)
CZAEM, or Capture Zone Analytic Element Model, is a single-layer model for simulating steady flow in homogeneous aquifers using the Analytic Element Method. It serves as a tool in the wellhead protection decision making process by delineating groundwater capture zones and isochrones of residence times. CZAEM supports a limited number of analytic elements that can accommodate fairly realistic boundary conditions, such as streams, lakes, and aquifer recharge due to precipitation. CZAEM generates output on groundwater capture zones and residence times. The model accurately defines capture zone boundaries by first determining all stagnation points and dividing streamlines in the flow domain.
