  • Flooding of lowland peatlands in Southeast Asia

    Vast lowland areas of Southeast Asia will be frequently and irreversibly flooded before the end of the century unless action is taken to stop the destruction of peatlands. A radical change in land-use is needed. In particular the palm oil and pulp wood sectors must stop developing new plantations on peat and plan to phase-out existing drainage-based plantations before they are flooded. If no ...

  • The toxic legacy of Thailand’s ‘Great Flood’ will remain long after the waters have receded

    This year’s unusually long rainy season has left many part of Thailand, Lao and Cambodia inundated and resulted in the worst flooding crisis in Thailand for at least 50 years. The provinces of the central plains and many districts in the north, east and west of metropolitan Bangkok are now effectively under water. The huge volume of floodwater is such that flood levels are 3 metres deep in ...

  • Enhancing resilience in urban water systems for future cities

    In future cities, urban water systems (UWSs) should be designed not only for safe provision of services but should also be resilient to emerging or unexpected threats that lead to catastrophic system failure impacts and consequences. Resilience can potentially be built into UWSs by implementing a range of strategies, for example by embedding redundancy and flexibility in system design, or by ...

  • Water quality monitoring following Hurricanes Katrina and Rita

    Following the passage of Hurricane Katrina, New Orleans was left with 80% of its land area flooded. In some locations, the flood waters were over 30 feet deep. In the heat and stagnation, the waters quickly became heavily polluted. Pump out operations began in early September 2005 to get the city dried out quickly. Lake Pontchartrain was the primary receiving water body. A variety of approaches ...

  • Protocols for Evaluating the Effects of Land-use Patterns and Runoff Management on Urban Streams

    ABSTRACTThe design of urban runoff management facilities generally includes peak shaving for flood control, and best management practices (BMPs) for removing pollutants from the runoff. A number of scientists have concluded that the combination of these two control practices, which were developed independently of one another, is not sufficient to protect aquatic ecosystems. But these conclusions ...
