The Physical Picture of Bali 4

Morfologi of Bali

     Morfologi the Balinese Province territory consisted of the area of the coastal plain, the river, the swamp, the lake, the volcanic plain, as well as the plain sendimen that had the shape of the gradient with the slope 0 - 5 % and the height revolved 0 - 25 m. above sea level. The condition for this morphology had the level of the erosion of the small surface, and several places were the area of the abrasion as well as the process of the active sedimentation, especially in the area of the Benoa Gulf, Singaraja, and Gilimanuk. The Alivium Lake plain that achieved the height between 1,000 - 1.230 metre above sea level was the area of the danger for the movement of the land like the landslide or land ruins and the rock from bank around it. The Aluvium Lake Batur plain had possibility the fall of the measuring rock boulder as far as sand, lapili and ash when an activity to this volcano happening.

     The area of hills with refined relief through to rough with the slope of the gradient through to steep (2 - 70 %) in the height 0 - 1.380 metre above sea level, especially in many bank the river that had the steep slope (>70 %). His rock consisted of the sediment rock (unified sand and the conglomerate) and the volcanic rock old that consist of breksi the volcano, lava, tufa that was hard and unified. The level of the erosion of the small surface until big. To the area berrelief was, the quite strong abrasion with several places was the area to make possible the landslide especially to conglomerate bedrock and in many bank that was steep.

     The area of the limestone rock (the Jimbaran Hill and Nusa Penida) had the slope of the slope of the gradient until rather steep (3 - 50 %) with several places >30 %, especially in many bank sea, was located in the height 0 - 210 metre above sea level. The level of the erosion of the small surface through to was with several places was the area of the abrasion and potential the movement of the land take the form of collapsen.

     Mountains reliefed soft until rough, his rock consisted of volcanic sediment from the Buyan Mountain - Beratan and Mount Batur took the form of the mudflow that was rather unified and the volcanic rock from Mount Agung take the form of tufa and the mudflow that was rather free. This area had the slope between 0 - 70 % and several places had the steep slope, especially in bank the river. This area was located in the height between 200 - 300 metre above sea level. The level of the erosion of the surface was classified as small until big, whereas the abrasion was still active for mountains reliefed soft through to was. The slope of the northern part and south-east Mount Agung and around Mount Batur was the area of the disaster of the danger. In several places, especially around the river valley that was nuclear-warhead in Mount Agung was the area of the danger, that is the cold mudflow current with several places was the area make possible the landslide. The mudflow current from Mount Agung spread in the north coast from the Tianyar Village to the Kubu Village.
