Simulation of Hot Mudflow Disaster with Cell Automaton and Verification with Satellite Imagery Data
نویسنده
چکیده
Minimization differences on Cellular Automata approach to predict new inundated area of hot mudflow on LUSI mud eruption disaster which occurred in Sidoarjo area is proposed. There are three characteristics of hot mudflow that is unique such as sur face material changes rapidly, surface temperature changes quickly and dike is constructed to avoid spill over. There are penetrations of hot mudflow through the dike and some landscape data on surrounding area of predicted cells. The proposed approach is powerful to simulate hot mudflow on this disaster. Simulation results are compared to SPOT/HRV imagery data as well as ASTER/VNIR and ASTER derived digital elevation model and also compared to the actual measured data acquired from local government. It is found that the influence due to lattice size is clarified together with validation of simulation methods used.

New Approach of Prediction of Sidoarjo Hot Mudflow Disastered Area Based on Probabilistic Cellular Automata
A new approach of prediction of Sidoarjo hot mudflow disaster area using cellular automata with probabilistic adjustment for minimizing prediction errors is proposed. Sidoarjo hot mudflow has some characteristics such as occurring in the urban area, huge-mud plumes, high-viscosity and surface temperature changes, so that it needs combined approaches of slow debris flow, and material changes cau...
