In this paper, a new methodology is proposed for simultaneous allocation of water and waste load in river basins. A nonlinear interval number optimization model is used to incorporate the uncertainties of model inputs and parameters. In this methodology, the bounds of the uncertain inputs are...

<Para ID="Par1">A physical model that consisted of a glass reinforced plastic model, constructed to a 1:25,000 horizontal scale and with a 1:125 vertical scale of the Severn estuary was designed and fitted into a tidal basin at Cardiff University. The model, which was first of its kind, was used to conduct...</para>

Groundwater constitutes the largest single source of fresh water in many parts of the world and provides a risk buffer to sustain critical water demands during cyclic and prolonged dry periods, especially in semi-arid and arid regions. However, unprecedented socio-economical growths are...

It is revealed that the water quality in Mae Moh Reservoir, Thailand, has been deteriorated by lignite mine drainage and power station effluent. This study aims to manipulate water quantity and quality to reduce environmental impacts in Mae Moh area through a model for water management. The...
