The existing methods of river evaluation tend to focus exclusively on water quantity; therefore, they do not provide a suitable methodology for integrated water management. In this study, research was carried out to develop an integrated river evaluation system that can simultaneously consider water quantity and water quality to improve the existing river evaluation methods. To this end, specific indicators were established to evaluate water quantity and water quality; moreover, an integrated evaluation formula was developed to express each indicator as an index. The integrated evaluation formula used additive functions and enabled integrated and comprehensive river evaluation through the sum of each indicator’s indices. The research subjects were rivers in the Paldang watershed, which surrounds important water resources in rep. of Korea. The rivers were analyzed using the study’s integrated river evaluation formula to identify the deteriorated grade of the water quality as well as the water quantity. Finally, the results of the integrated river evaluation rating were found to be poor or very poor. Based on this, the study determined that an integrated river management policy is required to simultaneously consider water quantity and water quality to restore the integrity of the rivers in the Special Countermeasures Area. The existing evaluations of rivers, which had been conducted only with a focus on water quantity, could be judged narrow or incomplete results. Based on this finding, it was also possible to identify an urgent need for a basic river management plan that can consider both water quantity and water quality organically. Ultimately, the study demonstrated that its methodology was able to make highly intuitive judgments about rivers’ current conditions; thus, it can be utilized to generate basic data for the establishment of customized river management policies.

Management Policies

Water resource management policies impact how water supplies are protected, collected, stored, treated, distributed, and allocated among multiple users and purposes. Water resource policies influence the decisions made regarding the siting, design, and operation of infrastructure needed to achieve the underlying goals of these policies. Water management policies vary by region depending on particular hydrologic, economic, environmental, and social conditions, but in all cases they will have multiple impacts affecting these conditions. Science can provide estimates of various economic, ecologic, environmental, and even social impacts of alternative policies, impacts that determine how effective any particular policy may be. These impact estimates can be used to compare and evaluate alternative policies in the search for identifying the best ones to implement. Among all scientists providing inputs to policy making processes are analysts who develop and apply models that provide these estimated impacts and, possibly, their probabilities of occurrence. However, just producing them is not a guarantee that they will be considered by policy makers. This paper reviews various aspects of the science-policy interface and factors that can influence what information policy makers need from scientists. This paper suggests some ways scientists and analysts can contribute to and inform those making water management policy decisions. Brief descriptions of some water management policy making examples illustrate some successes and failures of science informing and influencing policy.

Abstract Public participation in water resource management is crucial for community development and resource sustainability. Many studies on water resource management have been done on urban river systems, focusing on water quality, and concentrating mainly on the physical, chemical and biological parameters, while neglecting the social impacts. An example of this is seen in the Kaalspruit, a highly polluted river in the township of Tembisa. After the confluence with the Olifantspruit River, the Kaalspruit runs through the residential and highly industrialised areas of Clayville, Tembisa and Ivory Park in Johannesburg, South Africa. The aim of the study is to evaluate public perception, participation and attitudes towards water resource management in the Kaalspruit River, and to aid with a related community management plan. This was achieved by purposive and random sampling of relevant stakeholders and the public. Community knowledge was used to increase water quality awareness. The study revealed that those surveyed are discontented with the river's current state but are interested in rehabilitating it. Their participation highlighted the need for a community-based management plan for the river.

Abstract Water quality evaluation is a key task in water resource management and pollution control. Current evaluation methods are rooted in water quality index, which assesses the water quality based on the exact concentration of various pollutants. However, the interaction between the pollutants and the water environment should also be considered. This paper suggests a new approach, which integrates pollutant interaction with water environment and parameter uncertainty to water quality evaluation. The new approach is compared with traditional methods. Then, an inexact evaluation model, the integrated water quality evaluation model under uncertainty, is established in accordance with the proposed approach, in which catastrophe theory is used to deal with the ambiguous internal mechanism of the interaction between the pollutants and the water environment. As there are significant uncertainties in water quality evaluations, fuzzy random variables are employed to describe the inexact monitoring data. To solve the proposed model, a new algorithm is designed. The model is then applied to an actual case: Lake Chaohu, China. The results are compared between the proposed method and China's current evaluation method (i.e. max-index method). Some brief analysis and discussion are given about the results, which could be helpful in guiding environmental management decision-making.

Clean water according to Permenkes RI No 416 / Menkes / Per / IX / 1990 is water that used for daily needs whose quality meets health requirements and can be drunk after cooking, one of the government's efforts to meet the clean water needs of the community is the Pamsimas Program. The Pamsimas Program is one of the programs and concrete actions of the government (central and regional) with the support of the World Bank to improve and meet the needs of drinking water supply, sanitation to improve the level of public health, especially in reducing the number of diarrheal diseases and other diseases that are transmitted through water and the environment. Muaro Tombang Village, Sungai Manau Village and Bukit Kauman Village are the three villages in Kuantan Mudik Sub-District that have not had access to 100% clean water. Indicators of success and sustainability of the Pamsimas Program are the quantity and quality of water sources, management policies and management strategies for the Pamsimas Program. The quantity of water in the three villages in terms of discharge and minimum reservoir capacity meet the needs of the community, the water quality in the three villages there are several parameters that do not meet the quality standards of the Minister of Health Regulation No. 416 of 1990 concerning Clean Water Quality Requirements, so it needs to be treated for water Pamsimas Program. The community's perception of the socio-economic and management policies of the Pamsimas Program Muaro Tombang Village and Sungai Manau Village is included in the agreed category, while the community's perception of the socio-economic and management policy of the Pamsimas Program in the Bukit Kauman Village is in the neutral category. The right strategy used for the management of the Pamsimas Program in the three villages is the aggressive strategy (Growth Oriented Strategy), namely the development of the Pamsimas Program by utilizing the strengths of the opportunities that have been identified.

The National Rivers Authority of England and Wales is a non-departmental governmental regulatory body with a range of responsibilities for the water environment. These include pollution control, water quality improvement, flood defence, water resource management, fisheries management, conservation of the natural water environment, promotion of water based recreation and also navigation in some locations. Arising from the multiple use of river systems, their interactions and use requirements, the concept of Catchment Management Planning has been developed. Each river use should have an assigned objective and standard determined in respect of water quality, water quantity and river topography. Catchment Management Plans are prepared in consultation with interested parties. A review of some European river management suggests the size of some rivers and the responsibilities of relevant organisations exacerbates comprehensive and integrated river management.

Actionable Knowledge

Water quality measures for inland and coastal waters are available as discrete samples from professional and volunteer water quality monitoring programs and higher-frequency, near-continuous data from automated in situ sensors. Water quality parameters also are estimated from model outputs and remote sensing. The integration of these data, via data assimilation, can result in a more holistic characterization of these highly dynamic ecosystems, and consequently improve water resource management. It is becoming common to see combinations of these data applied to answer relevant scientific questions. Yet, methods for scaling water quality data across regions and beyond, to provide actionable knowledge for stakeholders, have emerged only recently, particularly with the availability of satellite data now providing global coverage at high spatial resolution. In this paper, data sources and existing data integration frameworks are reviewed to give an overview of the present status and identify the gaps in existing frameworks. We propose an integration framework to provide information to user communities through the the Group on Earth Observations (GEO) AquaWatch Initiative. This aims to develop and build the global capacity and utility of water quality data, products, and information to support equitable and inclusive access for water resource management, policy and decision making.

Evaluating trends in water quality indicators is a crucial issue in integrated water resource management in any country. In this study eight chemical and physical water quality indicators were analysed in seven river profiles in the River Laborec in eastern Slovakia. The analysed water quality parameters were biochemical oxygen demand (BOD5), chemical oxygen demand (CODCr), pH, temperature (t), ammonium nitrogen (NH4+-N), nitrite nitrogen (NO2--N), nitrate nitrogen (NO3--N), and total phosphorus (TP). Data from the monitored indicators were provided by the Ko�ice branch of the Slovakian Water Management Company, over a period of 15 years from 1999 to 2013. Mann�Kendall non-parametric statistical test was used for the trend analysis. Biochemical and chemical oxygen demand, ammonium and nitrite nitrogen content exhibit decreasing trends in the River Laborec. Decreasing agricultural activity in the area has had a significant impact on the trends in these parameters. However, NO2--N was the significant parameter of water quality because it mostly exceeds the limit value set in Slovak legislation, Regulation No. 269/2010 Coll. In addition, water temperature revealed an increasing trend which could be caused by global increase in air temperature. These results indicate that human activity significantly impacts the water quality.
