4th OJT Objectives
• gain knowledge, appreciation and experience on use of the Tank Model for flood forecasting
• configure a flood forecasting model based on the Tank Model for a selected catchment in the participant’s country
• calibrate the Tank Model and preparing the model for operational use in the participant’s respective organization
• develop expertise in writing simple macros (MSExcel) to automate model computations – a skill which can be used to customize the model and further enhance the model in the future
• Technical knowledge sharing among participants
