- Description
- In Australia, water resource simulation models using network linear programming (NLP) are widely used. This study identifies a range of potential problems when using NLP models at daily time steps, which, if not addressed, could result in poor outcomes. Four shortcomings are identified, namely failure of iteration to converge to good solutions, suboptimal water allocations due to a lack of foresight, lack of true optimization and serious computational inefficiency when evaluating drought security risks in highly reliable urban systems. It is shown how a number of enhancements to the WATHNET model have enabled each of these shortcomings to be addressed. The outcome is a far more robust and powerful framework than provided by the current generation of NLP-based models.
