These events have increased awareness about the need to invest in flood prediction and cooperate with neighbouring countries in developing such systems. Testing of the Accident Emergency Warning System (AEWS) in March 2007 on the Danube revealed that half of the stations did not react in a timely fashion. The development of the structure and content of a pilot Geographical Information System (GIS) on the Dniester River Basin as the information basis for water management is supported in an Environment and Security Initiative (ENVSEC) project.
