135 McLeod et al. fields after the tsunami. When the surface drainage systems were damaged by the tsunami, both the vertical and horizontal leaching of salts was restricted. On the other hand, the coarser soil in dryland fields is more permeable, hence more conducive to leaching. Figure 3. Areas that were flooded for a longer period are more saline, EM38 data from Lho Nga in August 2005 (left) and from a cluster of sites in Pidie District in October 2005 (right) In rice fields, good irrigation, water availability and water circulation affected the level and persistence of soil salinity problems. Rice fields that were under irrigation at the time of the tsunami event tended to be less saline than those fields that were dry. This suggests that seawater did not infiltrate into the already flooded soil, but most likely moved horizontally at the soil surface. The availability of fresh irrigation water and good drainage systems continued to be important after the tsunami. Both transects in site 5 (Figure 3) were flooded with seawater for more than three days after the tsunami. The owner of the paddock in site 5-2 was able to pump the saline water out while the farmer in site 5-1 could not. A good rice crop was observed in transect 5-2 in October 2005, while the crops in site 5-1 all died. However, after irrigation water became available in 2008 both sites had good rice crops. In some areas, agricultural lands have been exposed to tidal movements due to the loss of sand dunes. These areas will remain saline and unsuitable for normal cropping until new sand dunes or other protection from sea water is in place. CONCLUSION Electromagnetic induction technology, using the EM38 equipment has allowed rapid assessment of soil salinity in tsunami affected areas in Aceh. It allows monitoring of saline sites over time to assess their suitability for cropping after a tsunami. International Workshop on Post Tsunami Soil Management, 1-2 July 2008 in Bogor, Indonesia
