Fig. 2 Precipitation for Sempor and Wadaslintang (1993-2009) 3.3. NEXUS TOOL IMPLEMENTATION AND ANALYSIS The Nexus tool is used to aggregate and simplify the technical data (see table 3). But, before the data is used, all of them are reduced into average numbers for the last ten years, except for the sedimentation data availability for Sempor, which was last calculated in 1994. The data came from different sources: reports and previous studies. In applying the tool, an adaptation version is made based on the availability of data and the data needed for the models (WEAP-LEAP and CLEWS).
