An algorithm for real-time prediction of river stage dynamics using a Takagi-Sugeno fuzzy system is presented in this paper. The system is trained incrementally each time step and is used to predict onestep and multi-step ahead of river stages. The number of input variables that were considered in the analysis was determined using two statistical methods, i.e. autocorrelation and partial autoco...

A new tool for hydrokinetic energy potential assessment in rivers—HYDROKAL, which stands for a ‘‘hydrokinetic calculator’’—is presented. This tool was developed in the Fortran 90 programming language as an external module for the CCHE2D application, an existing two-dimensional hydrodynamic numerical model developed at the National Center for Computational Hydroscience and Engineering, Universit...

The world’s largest deltas are densely populated, of significant economic importance and among the most valuable coastal ecosystems. Projected twenty-first century sea-level rise (SLR) poses a threat to these low-lying coastal environments with inhabitants, resources and ecology becoming increasingly vulnerable to flooding. Large spatial differences exist in the parameters shaping the world’s d...

The relationships between water level and discharge along the river channel are vital for decision support systems in river basin management. Normally the reliability of the so-called rating curves along the river channel depends greatly on the accuracy and duration of the measured discharge and water level data. In the Elbe Decision Support System (DSS), the rating curves are combined with the...

The Pike River mine (PRM), an underground coal mine in New Zealand (NZ), exploded in 2010. This paper analyses the causes of the disaster, with a particular focus on the systems engineering and organisational contributions. Poor systems-engineering contributed via poorly designed ventilation, use of power-electronics underground, and placement of the main ventilation fan underground. Management...

The Tamarack State Wildlife Area in eastern Colorado is being investigated as a possible managed recharge project to redirect flows in the South Platte River for water quantity management. Two primary surface water/groundwater interactions exist at Tamarack: (1) between the South Platte River and alluvial aquifer and (2) between backwater sloughs, or secondary river channels, and the alluvial a...

The European project FIRMA (Freshwater Integrated Resource Management with Agents) aims to improve water resource planning by combining agent-based modelling and integrated assessment to describe physical, hydrological, social and economic aspects of water resource management in an integrated way. This paper describes an approach that couples an agent-based model with an integrated assessment m...
