Constructing total suspended solid modelling on Agathis Lake by employing resource modelling associates program

Abstract

This research uses Resource Modelling Associate (RMA) program to conduct a two-dimension model of Agathis Lake to analyse velocity and sediment transport distribution. The main programs are RMA-10 for velocity distribution and RMA-11 for the pollutant distribution. The sediment transport focuses on total suspended solids (TSS) pollutant. The research aims to construct total suspended solid model. Firstly, RMA Generation produces mesh of Agathis Lake. Next, RMA-10 and RMA-11 would perform both velocity and TSS simulation model to represent the actual condition. This research still gives temporary result due to limited sampling data. Calibration analysis of the model is needed to make the result of the program more accurate and more representative to the real condition.

2-D Numerical modelling of hydrodynamic and sediment transport in Agathis Lake

“…The present research provides further research result from initial findings [11,12,13]. Resource Modelling Associates (RMA) is employed to model hydraulic and water quality data in the study area, Agathis Lake.…”

“…This program generates velocity distribution on the system. The data for modelling under wetland scenarios conditions is similar to the existing condition by entering the value of the variables that are generated through the calibration result [11].…”

“…The data input in this model is the same as the RMA program model for Agathis Lake of the existing condition. Data in the form of variables that affect the results of RMA-11 is the result of calibration that has been done [11]. Figure 10-12 are samples of the results of the RMA-11 program running in the form of TSS constituents distribution at a certain time.…”

“…Resource Modelling Associates (RMA) is employed to model hydraulic and water quality data in the study area, Agathis Lake. This advanced research is developed from previous research [11]. The calibration analysis is conducted to make the Resource Modelling Associates (RMA) program result could represent the actual field data of Agathis Lake.…”

“…The research observes total suspended solids (TSS) as the main pollutant in Agathis Lake. The previous research [11] suggests to analyze the most representative water sampling location in Agathis Lake with the least sum of squared error (SSE) percentage. The current analysis is according to the physical existing condition.…”
