The paper presents the historical analysis of the human development of the Meuse and the Rhine rivers in the Netherlands. Causes and consequences of the geomorphological alterations of the rivers’ natural beds have been discussed. The paper provides facts and up-to-date hypothesis aimed to explain the process of new (nonindigenous) aquatic species emergence process caused by river water quality and biotopes restoration in the Netherlands.

Many rivers in urban areas in Indonesia are commonly used as raw water sources for drinking water purposes. Therefore, the water quality of the rivers needs to be maintained. River restoration program becomes a major priority in improving the water sector and environmental, particularly in big cities in Indonesia. Sugutamu River is one of the main rivers passing through the Depok City, West Province of Indonesia. High population . Stakeholder participations should be considered when implementing a participatory program in river restoration project. This program can be developed by increasing the awareness of the community. One of the most important communities is the ‘expert’ communities. In this research, economists, environmental specialists, river engineers, urban planners are selected as the ‘expert’ community. Questionnaires were distributed to the expert communities to investigate how the respondents concern about the importance of river water quality. The result shows that the awareness of the expert community on river water quality and its improvement is higher than on other aspects.

Organic Removal

A mathematical model is proposed to predict the removal of dissolved organic substances and the consumption of dissolved oxygen by attached biofilms in an open-channel flow. The model combines the biofilm equations with the conventional Streeter–Phelps type equations of river water quality by considering the mass transfer of organics and oxygen in the river water through the diffusion layer into the biofilm. It is assumed that the diffusion and reaction within the biofilm are of steady-state, and follow Monod kinetics. The model is solved numerically with a trial-and-error method. The simulation results of the model for an ideal case of river flow and biofilm show that the organic removal rate and oxygen consumption rate caused by the biofilm are greater than that by suspended biomass. The effects of diffusion layer thickness, flow velocity, and biofilm thickness on the change of river water quality are discussed.
