Outline of Final Research Achievements

On May 29, 2006, mud and gases began erupting unexpectedly from a hydrocarbon exploration well near Sidoarjo, East Java, Indonesia. The mud is being pumped into the Porong River, which then carries the mud to the ocean approximately 20 km to the east. The main objective of this study is to assess (1) the effect of mudflow on the river and estuary environment such as sediment deposition and water quality using the observed river cross sections and bathymetry data, (2) application of numerical models to the Poring River, and (3) propose most suitable countermeasure which causes minimum environmental impact.
