The ARDGISS team of Universitas Gadjah Mada (UGM) won the second place in Geographic Information System Innovation Challenge (GISIC) 2010. The first place was won by the University of Muhammadiyah Surakarta team and the third by the Bogor Institute of Agriculture team. The event was held at Bandung Institute of T echnology, 2 May 2010.
In the Information System Innovation contest, the team consisting of five Geography students submitted a paper entitled Spilling Flood Spatial Modeling with Peak Discharge Estimation Approach from Various Land Use Changes in Bodri Watershed of Kendal Regency. They are Wikan Jaya Prihantarto, Filialdi Nur Hidayat, Ardila Yananto, Yanuar Adji, and Muhammad Sufwandika.
Ardila Yananto said that the theme selection was based on the fact that Indonesia is a country frequently hit by floods. Ardila further described, the phenomenon of peak discharge fluctuations on the watershed outlet is most relevant to describe the likelihood of a flood. Geographic Information Systems integrated with Remote Sensing enables the creation of raster GIS-based spatial modeling related with the changes in the factors that influence the flooding. "The spatial model is formed by calculating the parameters of the flood by using a logical formula to determine the value of outlet peak discharge," he explained, Wednesday (2/6) in the Faculty of Geography of UGM.
Ardila said that through the analysis adopting rational method approach, the comparison of the peak discharge level at the outlet of the watershed (Q) with a maximum discharge capacity of the watershed outlet (CQ) can be conducted. Thus, he continued, the level of likelihood of flooding can be observed and flood susceptibility can be predicted.
