“…Moreover, in these studies, modeling practices differ substantially from those employed in conventional mathematical groundwater modeling [21][22][23][24]. Although such oversimplification (e.g., ignoring the spatial variability of groundwater systems) decreases model runtime, it also decreases model accuracy [24].…”

Groundwater depletion poses a significant threat in arid and semi-arid areas where rivers are usually ephemeral and groundwater is the major source of water. The present study investigated whether an effective water resources management strategy, capable of minimizing evaporative water losses and groundwater depletion while providing water for expanded agricultural activities, can be achieved through aquifer storage and recovery (ASR) implemented in conjunction with water storage in an ephemeral river. A regional development modeling framework, including both ASR and a dam design developed through system dynamics modeling, was validated using a case study for the Sirik region of Iran. The system dynamics model of groundwater flow and the comprehensive system dynamics model developed in this study showed that ASR was a beneficial strategy for the region's farmers and the groundwater system, since the rate of groundwater depletion declined significantly (from 14.5 meters per 40 years to three meters over the same period). Furthermore, evaporation from the reservoir decreased by 50 million cubic meters over the simulation period. It was concluded that the proposed OPEN ACCESSWater 2014, 6 2301 system dynamics model is an effective tool in helping to conserve water resources and reduce depletion in arid regions and semi-arid areas.

“…Coupled feedback loops, stocks, and flows are used to structure interactions among variables and to demonstrate the dynamic behavior of the whole system over time. The model was originally developed during the mid-1950s (Forrester, 1971) and has been extensively used to address a wide variety of environmental and ecological studies, including tree growth (Pan and Raynal, 1995), lake eutrophication assessment (Vezjak et al, 1998), bioavailability of metals in wetlands (Wood and Shelley, 1999), groundwater recharge (Abbott and Stanley, 1999), waste management (Dyson and Chang, 2005), water reallocation (Elmahdi et al, 2007), and wastewater treatment (Xuan et al, 2010(Xuan et al, , 2011). Thus, system dynamics modeling is well suited for studying N transformations due to the cycling and feedback feature of N species in stormwater management, although few studies have been performed for such purposes.…”

System Dynamics Modeling of Nitrogen Removal in a Stormwater Infiltration Basin with Biosorption‐Activated Media

Stormwater infiltration basins, one of the typical stormwater best management practices, are commonly constructed for surface water pollution control, flood mitigation, and groundwater restoration in rural or residential areas. These basins have soils with better infiltration capacity than the native soil; however, the ever-increasing contribution of nutrients to groundwater from stormwater due to urban expansion makes existing infiltration basins unable to meet groundwater quality criteria related to environmental sustainability and public health. This issue requires retrofitting current infiltration basins for flood control as well as nutrient control before the stormwater enters the groundwater. An existing stormwater infiltration basin in north-central Florida was selected, retrofitted, and monitored to identify subsurface physiochemical and biological processes during 2007-2010 to investigate nutrient control processes. This implementation in the nexus of contaminant hydrology and ecological engineering adopted amended soil layers packed with biosorption activated media (BAM; tire crumb, silt, clay, and sand) to perform nutrient removal in a partitioned forebay using a berm. This study presents an infiltration basin-nitrogen removal (IBNR) model, a system dynamics model that simulates nitrogen cycling in this BAM-based stormwater infiltration basin with respect to changing hydrologic conditions and varying dissolved nitrogen concentrations. Modeling outputs of IBNR indicate that denitrification is the biogeochemical indicator in the BAM layer that accounted for a loss of about one third of the total dissolved nitrogen mass input.

“…System dynamics research, similar to the Rome study, resulted in important changes in certain fields such as business systems (Sterman, 2000), ecological systems (Grant, Pedersen, & Marín 1997), socio-economic systems (Forrester, 1969, 1971& Meadows, 1973, agricultural systems (Saysel, Barlas, & Yenigun, 2002), political decision systems (Nail, Gelanger, Klinger, & Peterson 1992) and environmental systems (Vizayakumar & Mohapatra, 1991;Vezjak, Savsek, & Stuhler, 1998;Ford, 1999;Wood & Shelley;1999, Abbott & Stanley, 1999Deaton & Winebrake, 2000;Guo, Liu, Huang, Fuller, & Yin, 2001). Inspired by this body of research, system dynamics researchers aimed to improve the quality of education by adapting this approach to the field of education.…”

The main goal of this research is to study the effect of modelling with system dynamics on learning. Specifically, this research studies if using inductive or deductive learning methods applied during modelling with system dynamics has any effect on problem solving skills of students. This research has three other goals: Firstly, the successful application of system dynamics approach in teaching environmental topics. Secondly, helping students to be aware of the environmental problems. Thirdly, helping students to build solution-oriented system dynamics models. An experimental design without control group with pretest/posttest is used in the research. The sample of the research consists of 40 students at 7th grade. Experiment continued an hour per week for the entire semester of 14 weeks. The students in the experiment group 1 developed their models using inductive method. The students in the experiment group 2 developed their models using deductive method. Problem solving skill inventory developed by Heppner and Petersen (1982) was used for data collection. The data collected was analyzed statistically. As part of the statistical analysis, the researcher evaluated the model records developed by students, interviews done with students and observational records of teachers. Statistically significant differences were observed in the problem-solving skills of students in both groups after the experimental study. The increase in the mean scores for problem solving skills of the experimental group 1 was higher than the increase in the mean scores of the students in the experimental group 2. System dynamics approach, which is effective in decision making process, also plays an important role in improving students' problem-solving skills.
