The water quality management tool RIONET for river basins has been developed with regard to the EU Water Framework Directive. The management tool can simulate the water quality in catchment basins not only in the dimension of a single river but in whole river networks. A submodel of the IWA River Water Quality Model No. 1 is used in RIONET. The river model is based on the assumption that self purification processes in the river takes place both in the benthic biofilm and the bulk water phase. Laboratory experiments with sediment cores underline the major role of the benthic biofilm. The input parameters of the management tool such as volumetric flow rates from waste water treatment plants and flow velocities and discharge in the main river and its tributaries can be loaded directly from geographic information systems (GIS). The subcatchment basin of the river Bode in Saxon Anhalt was used for test runs of RIONET.

The tidal rivers of the Humber Estuary System experience depletion of dissolved oxygen in dry, summer weather as a result of the pollution received from effluent discharges and the rivers of industrial Yorkshire. A suite of mathematical models has been developed to predict dissolved oxygen saturation and the concentration of related substances. Computer simulations using the models have been carried out to assess the effects of freshwater flow and oxidisable pollutants on dissolved oxygen levels in the estuary system. The models provide a practicable, water quality management tool for the Humber Estuary.

<p class="Els-Abstract-text">Water sustainability needs an integrated approach to meet the water need of the present without compromising the ability of future generations to meet their own need of water. It includes water security and water scarcity. The water demand is increasing every year, while the planet’s capacity to sustain increasing demands for water is challenged. The main global water problems fall into three categories. The first is too much of it, secondly is too little of it and thirdly, it is too dirty. The first category is due to extensive flooding, the second category is due to serious drought and the third category is due to pollution and misuse of water which needs water quality management. Nowadays, there are 1.2 × 10<sup>9</sup> people live in areas of water scarcity and 2.6 billion people in global are lacking safe water supply. There are (6 to 8) × 10<sup>6</sup>humans being are killed each year from water-related disasters and disease. In Indonesia, there is about 37 × 10<sup>6</sup> people lack access to safe water due to water quality issue. In this paper, emerging trends in water quality management to support water sustainability and the water-energy nexus will be discussed.</p>
