“…It requires constructing the unique causal loop diagrams or stock and flow diagram to form a system dynamics model for applications (Forrester, 1961(Forrester, , 1968Randers, 1980;Vizayakumar and Mohapatra, 1993). System dynamics modeling has been used to address practically every sort of feedback system the application matrix has covered several issues, including environmental impact analysis of coalfields (Vizayakumar andMohapatra, 1991, 1993), lake eutrophication assessment (Vezjak et al, 1998), pesticide control (Ford, 1999), wetland metal balance (Wood and Shelley, 1999), groundwater recharge (Abbott and Stanley, 1999), lake watershed management (Guo et al, 2001), river pollution control (Deaton and Winebrake, 2000), and solid waste management (Mashayekhi, 1993;Sudhir et al, 1997;Karavezyris et al, 2002;Dyson and Chang, 2005).…”

Constructed wetlands have been popular in ecological engineering regime; yet, modeling the physical, chemical, and biological processes within these wetlands is a long-standing challenge in the past decades. In concert with our field-scale pilot testing of a new-generation subsurface upflow wetland (SUW) system, this article highlights an advancement of modeling the SUW system with a layer-structured compartmental simulation model. This is the first wetland model of its kind to address the complexity between plant nutrient uptake and medium sorption. Such a system dynamics model using STELLA Ò as a means for a graphical formulation was applied to illustrate the essential mechanism of the nitrification and denitrification processes within a sorption mediumbased SUW system, which can be recognized as one of the major passive on-site wastewater treatment technologies in this decade. Model calibration and validation received fairly good R-squared values of 0.9998 and 0.9644, respectively. Such good agreement with the measured data confirms that the developed system dynamics model may provide a reliable tool for designing this particular type of constructed wetland. This work also entails the significant movement of linking green building with green infrastructure as part of the urbanization for nature.

“…This capability has been very useful in analyzing and recommending policy decisions in management and social systems (Mohapatra et al, 1994). Since the works on SD reported by Forrester (1961Forrester ( , 1968Forrester ( , and 1969, the method has been applied to a number of environmental studies, such as naural resource management, energy system planning, environmental impact assessment, and solid waste management (Meadows et al, 1973;Naill et al, 1992;Vizayakumar et al, 1991Vizayakumar et al, , 1993Mashayekhi, 1993;Clemson et al, 1995).…”

“…Proposed initially by Jay Forrester at MIT in 1956, the system dynamics (SD) methods has been hrther developed and widely applied in a variety of disciplines such as industrial systems, corporate planning and policy design, energy and environment, urban dynamics, and public management and planning in the second half of the 201h century (Forrester, 1961(Forrester, , 1971Coyle, 1977;Wang, 1988;Nail1 et al, 1992;Vizayakumar and Mohapatra, 1993;Mohapatra et al, 1994;Tang et al, 2007). The essence of the SD method is its focus on feedback processes.…”

This study developed a prototype of an environmental assessment tool, SEA-LUP-SD, based on the system dynamics model. SEA-LUD-SD can simulate and evaluate information feedback of land use plan options and three related systems, population change, economic development, and environment conditions. This tool was then applied to the Shanghai land use master plan (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) and three other hypothetical planning options to compare the corresponding environmental impacts of different plan scenarios. This study proved that the integration of system dynamics and the framework of strategic environment assessment (SEA) has the great potential to provide urban managers and planners an effective technical plagorm to compare a series of "what if" scenarios for the entire planning horizon and to formulate policy recommendation on the basis of the simulation results. In addition, SEA-LUD-SD can help promote public participation in environmental decision-making processes and to educate decision-and policy-makers about the significance of sustainable development in tangible operational terms rather than through political rhetoric in the context of the China j . post-reform political economy.
