“…System dynamics can better solve this problem by examining the role of decision-making and feedback relationships in the system through computer simulation (Forrester, 1958;Ross and Chang, 2021;Shal and Laberiano, 2021). Finally, we used the goodness of fit method to investigate the fitting degree of the simulation data and the actual value and verified the validity of the system model (Pinto and Sooriyarachchi, 2021;Shalabh, 2021). Through the combination of qualitative and quantitative research, we discussed the internal influence of institutional support on the coalbed methane industry.…”

Accelerating the construction of a low-carbon, safe, and modern energy system is becoming a critical developmental path toward solving the climate change problem. China provides institutional support in various ways for this clean and efficient new energy, but there is still a gap between the developmental scale and the planned target. Considering the theory of system support and the coalbed methane industry, we combed the existing institutional support for the coalbed methane industry based on grounded theory and defined the initial model. We used the system dynamics method to construct and simulate the model and verified the system’s effectiveness by using the goodness of fit. The results show that institutional support promotes the development of the coalbed methane industry, and the interaction between the two forms a dynamic system. Based on the sensitivity analysis method, the enlightenment of the management with respect to the improvement of the development of the coalbed methane industry was obtained. Firstly, the management of coalbed methane mining rights should be supervised and large-scale utilization should be strengthened. Secondly, the central government’s subsidies should be raised and local governments should be encouraged to provide support. Thirdly, technological innovation should be enhanced and fair competition should be ensured.

The study focused on analysing the eutrophication indicators of the Krishnagiri Reservoir Project (KRP) using the Water Quality Analysis Simulation Program (WASP). The reservoir was divided into six segments to simulate the indicators, and field measurements from 2015 to 2018 were used to calibrate the model while 2019–2022 were used to validate it. The results showed that the model predictions were in good agreement with the measured values, indicating the reliability of the model. The study assessed the impact of nutrient loads on dissolved oxygen, nitrate, phosphate, and chlorophyll-a. Four nutrient loading scenarios were simulated, and the most effective scenario (Scenario 4) involved a 75% reduction in nutrient load, which increased the reaeration rate by 1.47% and decreased chlorophyll-a concentrations by 88%. The study concluded that maintaining nitrates below 2.5 mg/L and phosphates below 0.75 mg/L could help restore the KRP reservoir's trophic status from hypereutrophic to mesotrophic. Overall, the study demonstrated the use of the WASP model in developing nutrient loading scenarios to manage reservoir water quality effectively. The findings could help policymakers and managers make informed decisions about reducing nutrient loads and restoring the trophic status of eutrophicated reservoirs.
