26.1 Introduction

In environmental management systems, intelligent decision support is utilized in hopes of facilitating more efficacious use of scarce environmental resources, particularly by adapting resource allocation and system operation to user demand, resource availability, and environmental conditions. Intelligent environmental decision support systems (EDSSs), which make use of cyber infrastructure for computing services such as automated reasoning, have been developed to this end. The physical infrastructure that supports environmental management is monitored, controlled, and guided by the cyber infrastructure; creating a cyber-physical system (CPS) where embedded computing and communication capabilities are used to streamline and fortify the operation of the physical system [1, 2]. Real-time data collected by sensors from the physical infrastructure ...
