57 Rachman et al. Figure 2. Distribution of tsunami mud in Aceh Besar and Banda Aceh, July 2005 Figures 3, 4 and 5 showed the ECe, concentration of Na and Cl - by soil depth at 6 selected sites eg. Cot Lheu Rheng (A), Seukeu (B), Panteraja (C), Tanjung (D), Nusa (E) and Lampineung (F). In general, the soluble salts at the surface soil has been reduced significantly both by natural flushing and leaching. Since there is no significant increase in the Cl - concentration at the deeper depths, we may conclude that the soluble salts reduction was mainly due to removal of salts in surface water after heavy rainfall as drainage system improved. However, some of the soluble salts have been leached downward to increase the ECe at the deeper depth to high level >5 dS/m. The downward movement of soluble salt may have occurred mostly during the first week after tsunami where standing sea water lasted for 3 to 6 days. The downward movement would also have been driven by rainfall during the period. The high sodium concentration may have caused soil dispersion of soil colloids to enhance surface sealing and clog soil pores as they move down the profile during rainfall (Emerson dan Bakker, 1973). Increased surface sealing and soil density can cause a wide range of problems, such as delayed emergence due to lack of oxygen, waterlogging, runoff, and reduce microbial activities.
