The results of the shortest path between each ETC to DRC in each flooding Zone (I-IV) were here identified using Network Analysis with closest facilities algorithm. Detail of ETC name, DRC, the shortest distance and times before and after water inundation over road network in Flooding Zone I to Zone IV was summarized as shown in Table 6.9. Example of shortest road between DRC and ETC before and after dam-break in each DRC was demonstrated in Figure 6.16 to 6.19.
As shown in Table 6.9, before water inundation over road network the shortest distance between ETC to DRC was 1.246 km within 2 minute located between Ban Dan Makham Tia School and Dan Makham Tia district, while the longest distance between ETC to DRC was 43.743 km within 54 minute located between Khao Din and Dan Makham Tia district. In contrast, after water inundation over road network the shortest distance between ETC to DRC was 1.246 km within 2 minute located between Ban Dan Makham Tia School and Dan Makham Tia district, while the longest distance between ETC to DRC was 80.617 km within 107 minute located between Ban Thung Nakkharat School and Dan Makham Tia district.
