Analog‐Digital Models of Stream‐Aquifer Systems ^a

Abstract

ABSTRACT The best features of analog and digital computers were combined to make a management model of a stream‐aquifer system. The analog model provides a means for synthesizing, verifying, and summarizing aquifer properties; the digital model permits rapid calculation of the effects of water‐management practices. Given specific management alternatives, a digital program can be written that will optimize operation plans of stream‐aquifer systems. The techniques are demonstrated by application to a study of the Arkansas River valley in southeastern Colorado.
