Predictability of stream flow and rainfall based on ENSO for water resources management in Sri Lanka

columbi Summary We investigate the viability of using El Niño–Southern Oscillation (ENSO) and sea surface temperature (SST) data to predict seasonal streamflow for one of the major rivers in Sri Lanka, the Kelani, using correlation analysis, contingency tables, and principal component analysis. The agricultural seasons in Sri Lanka are Yala (April–September) and Maha (October–March). The correl...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Flood Management from the Perspective of Integrated Water Resource Management

The Associated Flood Management Programme of the World Meteorological Organisation and Global Water Partnership (2002) has suggested that there are a number of implications for flood management. he first of these is to recognise that the catchment is a system. If we consider the functioning of the catchment; it is a dynamic system in which there are exchanges and movements of sediment, water an...
