“…Due to excessive pollutant discharge and inappropriate regulation of water resources over the past decades, the structure, function and health of many freshwater ecosystems in China have been degraded to the point that they can no longer support biodiversity (Wang et al, 2012). To protect the ecological function of water resources a certain amount of water must be left in rivers and lakes, and this is known as the ecological reserve, sometimes called Ecological Water Requirements (EWRs) (Acreman and Dunbar, 2004).…”

“…such assessment it is important to confirm that the model adequately reflects the current system performance (Schueler 1987;Hamed et al 2004;Mjalli et al 2006;Wang et al 2012;. As such, the main objective of this research was to calibrate PCSWMM for the current Cha-Am aerated lagoon treatment system configuration and current contributing area conditions, using the treatment fraction approach and a Monte Carlo simulation with a specific focus on total suspended solids (TSS), total Kjeldahl nitrogen (TKN), Escherichia coli (E. coli) and chemical oxygen demand (COD).…”

Water quality around Cha-Am, Thailand is of prime concern because of its extensive oceanfront beach area. Cha-Am uses an aerated lagoon system consisting of three ponds and a natural wetland to treat the municipal wastewater. A personal computer version of the storm water management model, PCSWMM, was used to simulate the effluent quality of the treatment system. Water quality samplings for total suspended solids (TSS), total Kjeldahl nitrogen (TKN), Escherichia coli (E. coli), chemical oxygen demand (COD), as well as evaporation measurements, were conducted on a bi-weekly basis for three months to calibrate the model. The four ponds were considered as four storage zones in the model. Based on the observed water quality data distribution, Monte Carlo simulation was used (1 000 iterations, 20 times) to get the most probable input concentration for each pond to determine the appropriate treatment fractions for the model. Data on daily inflow rates, pump operation and bathymetric survey also were obtained from the system operator as model input. The dynamic wave method was used with observed inflow rates to generate a continuous water quality simulation from 2015-07-19 to 2015-09-12. Observed mean treatment efficiency was 51.9%, 77.3%, 99.6% and 9.4% for TSS, TKN, E. coli and COD respectively. Observed concentrations at the outlet ranged between, 10 mg/L to 25.5 mg/L, 0.98 mg/L to 3.92 mg/L, 0.1 CFU/100 mL to 260 CFU/100 ml and 48 mg/L to 119 mg/L for TSS, TKN, E. coli and COD respectively. The treatment fraction approach in PCSWWM was able to accurately represent the outlet concentrations of TSS, TKN, E. coli and COD.

“…Such delineation is appropriate for small-scale shallow lakes, but is not sufficient to capture large spatial variations in hydrodynamics and constituent transport between different areas where the characteristics of soil, topography, water temperature, available nutrients, and vegetation show spatial heterogeneity within middle-scale or large-scale lakes. The well-mixed box model might contain a large margin of error (Wang et al, 2012). It is essential to construct a lake ecological model that can simulate ecological change considering spatial variations.…”

Abstract. Environmental/ecological models are widely used for lake management as they provide a means to understand physical, chemical, and biological processes in highly complex ecosystems. Most research has focused on the development of environmental (water quality) and ecological models, separately. Limited studies were developed to couple the two models, and in these limited coupled models, a lake was regarded as a whole for analysis (i.e. considering the lake to be one well-mixed box), which is appropriate for small-scale lakes but is not sufficient to capture spatial variations within middle-scale or large-scale lakes. In response to this problem, this paper seeks to establish a zoning-based environmental-ecological coupled model for a lake. Hierarchical cluster analysis was adopted to determine the number of zones in a given lake based on hydrological, water quality, and ecological data analysis. The MIKE 21 model was used to construct 2-D hydrodynamics and water quality simulations. STELLA software was used to create a lake ecological model that can simulate the spatial variations of ecological condition based on flow field distribution results generated by MIKE 21. Baiyangdian Lake, the largest freshwater lake in northern China, was adopted as the study case. The results showed that the new model is promising for predicting spatial variations of ecological conditions in response to changes in lake water quantity and quality, and could be useful for lake management.
