“…Based on the reasonable model results for current conditions, the model can be used with some confidence to assess the impact of future development scenarios and population change on the pond operation at a planning level. Design and operation decisions can be made by simulating the physical plant operation, which is cost effective and time saving (DeVries and Hromadka 1993;Simachaya 2002;Rees and Schoen 2009;Fan et al 2015). The next step in this research will be to link the pond system with the collection system represented by PCSW-MM and explore the impact of future development scenarios on treatment efficiency.…”

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.

“…Tang et al [17] built a 1D hydrodynamic water quality model to make analysis of the pollutant diffusion process after sudden water pollution in the Main Route Project of the MRP; set a scene with three water flow rates, four pollutants, and three pollution amounts; and recommended reasonable emergency measures. Fan et al [18] simulated the diffusion process of pollution due to a fluorescein sodium point source in the basin of the Paraiba do Sul River under many scenes. Samuels et al [19] performed simulation of the transfer process of pollutants in rivers.…”

Water is an important basic resource for human survival, social and economic development, and ecological environment stability [1]. With population growth, economic development, and climate change, many countries and regions face water shortage due to the uneven spatial-temporal distribution of water resources [2, 3]. Shortage of water resources will affect food safety, economic development, and ecological environment health. This is one of the major difficulties that the world has to face in the future and a major obstacle to realize sustainable development [4, 5]. It is an important way to solve the crisis of water resources in some areas by carrying out water diversion projects to transfer water from the areas where water is abundant to the places lacking of water [6]. 1.1 Main long-distance water diversion projects in the world It has been a long history of building water diversion projects by all the countries around the world. The earliest project can be traced back to 2400 BC in the ancient Egypt, transferring the water of the Nile River to irrigate the southern Ethiopia plateau. With the development of social economy, the distance, range, transferable water amount, benefit, construction, and management levels of water diversion projects are gradually improved [7]. Until now, 350 long-distance water diversion projects have been built in at least 39 countries [8]. The following are some typical ones in the world. 1.1.1 California north-to-south water diversion project (America) The main work of this Project Phase I was completed in 1973, successfully providing industrial and living water for 17 million people centering around Los Angeles. The main canal is 1138 km long in total, with a multi-year average water diversion amount of 5.2 billion m 3 and a water diversion flow of 284 m 3 /s.

“…Often, proprietary commercial packages are used for automatic processing in a GIS environment. However, the use of free and open source software has been increasing, which has shown promising potential for the management of water resources (CASTRO et al, 2015;FAN et al, 2015;SWAIN et al, 2015;FANTINEL;BENEDETTI, 2016). Currently there are several free software for GIS, ranging from desktop systems capable of analyzing data and compose printed maps to database systems for the purpose of storage and management of geographic data.…”

This work aims to describe the potentialities of a set of tools of the Geographic Resources Analysis Support System (GRASS) for hydrographic basin analyzes. For this purpose, the morphometric characterization and the definition of the drainage system of the Manso river basin, in Mato Grosso, were performed. Initially, the Digital Elevation Model (DEM) was corrected and, based on the location of the main river mouth, the morphometric parameters were calculated for the basin. It has been found that GRASS is a viable alternative for those users who cannot afford the commercially available Geographic Information Systems (GIS) and/or for those who wish to develop their models coupled to a GIS.
