The carrying capacity of receiving water bodies is one of the important data for water quality management, pollution source control towards harmonizing with the economic development and environment protection. Therefore, this research aimed atevaluating the carrying capacity of receiving water bodies in the south of Binh Duong province up to 2030. 06 key water quality indicators (COD, BOD, TSS, PO43--P, NO3--N, NH4+-N) were exmained with 02 wastewater treatment scenarios. Results showed the investigated area hardly had carrying capacity for NH4+-N and PO43--P, followed by TSS, BOD, and COD. In case of improving wastewater treatment status till 2030, the carrying capacity of receiving water bodies would be increased, but not significant. The carrying capacity of several basins needs to be paid special attention are: Suoi Con 1 basin (BOD, COD, NH4+-N), Suoi Cai basin (BOD, TSS and NH4+-N), the upstream of Cay Bang – Cau Dinh basin (BOD, COD, TSS, NH4+-N), the upstream of Chom Sao – Rach Bung basin (05 parameters, excepting NO3--N), the upstream of Binh Hoa – Vinh Binh basin (BOD, COD, PO43--P, NH4+-N). These findings are an important basis for formulating strategies and proposing measures for local pollution source control and surface water management.

The South of Binh Duong province has undergone various economic activities and significantly contributed to the local budget, but has also posed adverse impacts on environment where the decrease in surface water quality is a vital of concern. To evaluate the change in surface water quality and carrying capacity of receiving water bodies in southern waterways of Binh Duong province (not mentioned in this work), the surface water quality data was recalled from 25 monitoring stations during 2012 – 2016 and sampled at 93 locations in the dry season of 2017. In the period of 2012 – 2016, the SWQ fluctuated from very poor to good level (WQI = 20 – 88). The sites of interest were the Chom Sao canal (RSG5), Bung Cu stream (RĐN2), and Thi Tinh river (RTT1) (WQI <7) with high concentrations of BOD5, COD, and coliform, etc. In the dry season of 2017, the SWQ was ranged from very poor to good level (WQI = 16 – 88). Some monitoring locations should be taken into consideration were STT2 in Thi Tinh River, MC25 in Cau Dinh stream, MC50 in Cat - Bung Biep stream, and MC91 in Cai stream due to high concentrations of SS, turbidity, NH4+-N, BOD5, COD, etc. Accordingly, it is necessary to continue studying and assessing the waste water generation, the carrying capacity of receiving water bodies in relation to the local socio-economic development plans, as a basic for local surface water management and the sustainable development.

Components of the integrated water quality management and planning process are described. The process is initiated by the Use Attainability Analysis (UAA) in which the ambient water quality-use based standards are justified and/or modified for the water body for which water quality management is being considered. The UAA has three components: (1) Water Body Assessment, (2) The Total Maximal Daily Load (TMDL) Process, and (3) Socio-economic Analysis. The first component identifies whether the receiving water body and watershed have a water quality problem and, subsequently, separates such water bodies into those where the water quality problem is caused by natural loads or conditions and those where man-made pollution inputs cause unacceptable water quality deterioration. The TMDL process separates water bodies into those for which water quality goals can be achieved by present and future mandated abatement of point and nonpoint sources (effluent limited water bodies) and those mandated abatement will not achieve the water quality goals (water quality limited water bodies). Extensive water quality management and expenditure of public funds is justified for the latter cases. Watersheds and receiving water bodies which are adversely affected predominantly by nonpoint (unregulated) discharges are declared as impaired and should be managed. Both reduction of waste discharges and enhancement of waste assimilative capacity-habitat restoration of the receiving water body should be considered in management of water quality limited receiving waterbodies.

A computer program based on expert system software was developed and proposed as a prototype model for water management to control eutrophication problems in receiving water bodies (Suzuki etal., 1988). The system has several expert functions: 1. data input and estimation of pollution load generated and discharged in the river watershed; 2. estimation of pollution load run-off entering rivers; 3. estimation of water quality of receiving water bodies, such as lakes; and 4. assisting man-machine dialog operation. The program can be used with MS-DOS BASIC and assembler in a 16 bit personal computer. Five spread sheets are utilized in calculation and summation of the pollutant load, using multi-windows. Partial differential equations for an ecological model for simulation of self-purification in shallow rivers and simulation of seasonal variations of water quality in a lake were converted to computer programs and included in the expert system. The simulated results of water quality are shown on the monitor graphically. In this study, the expert system thus developed was used to estimate the present state of one typical polluted river basin. The river was the Katsura, which flows into Lake Sagami, a lake dammed for water supply. Data which had been actually measured were compared with the simulated water quality data, and good agreement was found. This type of expert system is expected to be useful for water management of a closed water body.

In traditional waste load allocation (WLA) decision making, water quality-related constraints must be satisfied. Fuzzy models, however, can be useful for policy makers to make the most reasonable decisions in an ambiguous environment, considering various surrounding environments. We developed a fuzzy WLA model that optimizes the satisfaction level by using fuzzy membership functions and minimizes the water quality management cost for policy decision makers considering given environmental and socioeconomic conditions. The fuzzy optimization problem was formulated using a max–min operator. The fuzzy WLA model was applied to the Yeongsan River basin, which is located in the southwestern part of the Korean Peninsula and Korean TMDLs were applied. The results of the fuzzy model show that the pollutant load reduction should be increased in the Gwangju 1 and Gwangju 2 wastewater treatment plants (WWTPs) and in subcatchments with high pollutant load. In particular, it is necessary to perform advanced wastewater treatment to decrease the load of 932 kg ultimate biochemical oxygen demand (BODu)/day in the large-capacity Gwangju 1 WWTP and reduce the BODu emission concentration from 4.3 to 2.7 mg/L during the low-flow season. The satisfaction level of the fuzzy model is a relatively high at 0.81.

Water management becomes a complex issue when considering the large number of water-rights-of-use like drinking water production, recreation, receiving water, transport on and ecological quality of the water bodies. Recent changes in the legal requirements concerning water management on European scale (EC Water Framework Directive, 2000/60/EC) highlighted the need for appropriate means for monitoring water quality and exchange of water quality data. Indirect measurement of water quality using surrogate parameters (chemical and physical-chemical parameters) can be automated at a high accuracy level. This was shown over the past years by national and international research projects. In 2001 such a research project has started in Austria focusing on the installation and operation of a pilot water quality network, which is suitable for application at several points of interest of water management, i.e. sewer networks, wastewater treatment plants and receiving water bodies. The paper describes the operational problems and experiences of collecting data over a period of one year in the Danube River downstream of Vienna. The sensors are installed in situ, directly in the river, without any bypass system. The first evaluation of the measurements shows that the values are reliable and therefore applicable to further interpretations.

Abstract The Siret River are used as raw water source for different municipal water supply systems, yet the Siret River are used as receiving bodies by some inhabitants and industry. In the study the quality of the Siret River water was determinate using a Water Quality Index (WQI). Results are presented from a field study performed on the Bistrita, Moldova, Suceava, Siret, Şomuzu Mare, Trotuş and Tributary River in the study area Siret Basin Romania. The main objective of this study was to determine is to find correlations land use to indicators physical-chemical of water quality, to investigate pollution source is more responsible for river water quality. This is of interest not only research context, but also for supporting and facilitating the application analysis postullend in the Water Framework Directive (WFD) (2000/60/CE) for the establishment of programmers of measures. For this purpose a slightly impact pollution source municipal wastewater treatment, land uses, urban, forest, agriculture and mining was selected and intensively monitored during six years January 2006 - December 2011, sampling was determined to meet the WFD standards for confidence in twenty two different control section of the Siret Basin. The main measures to reduce emissions to the Siret River were calcium, ammonium, sulfate, residue fixed (RF), sodium, chloride, free detergent and municipal wastewater treatment, concentrated on point emission. The main contributor to diffuse this parameters increased when more percentage of land was dedicated to industry and urban and less to forest and mining.
