DSD-SEA 2019 Seasonal drought forecasting using state-of-the-art hydro software in Indonesia-Sudono

  1. 1. Seasonal drought forecasting using state-of-the-art hydro software in Indonesia Irfan Sudono (Research Centre for Water Resources / PUSAIR, Indonesia) Arnejan Van Loenen (Deltares, The Netherlands)
  2. 2. Challenges in Indonesia Why ? 1. Population increases, lifestyle changes, the need for water increases 2. Urbanization (ground water extraction, deforestation, increasing water demand 3. Environmental damage, (causing DF, erosion, sedimentation, and pollution) 4. Climate Change Report from the IPCC (Intergovernmental Panel on Climate Change) in 2013.Confirming that in the future at the beginning of the 21st century (2016-2035) and the end of the 21st century (2081-2100), on a global scale the climate projection will get worse 1. The incidence of heavy rain (both in terms of frequency, intensity, or amount) will increase with the category "very likely" 2. While the intensity and duration of drought are in the category of "medium confidence"
  3. 3. INTRODUCTION To tackle Indonesia’s challenges on Water Resources Management, it is essential that all existing water data is available for the stakeholders. Currently the data, are spread over the institutes and organisations that are involved in integrated water management. PusAir and BMKG took the initiative to set-up a joint Pusat Studi Hydroinformatics (PSH, or Water Centre of Excellence) which it should form the platform that connects most of the activities and disseminates the results to the stakeholders. The PSH is supported by a dedicated server system, running the software, tools, databases and interfaces that are produced within the whole JCP program. Delft-FEWS hydrological model and data integration platform used as the platform software to accommodate all functionalities required for the SI-PSH. PusatStudiHydroinformatics

  10. 10. GPM (Global Precipitation Measurement)
  11. 11. ECMWF (European Centre for Medium-Range Weather Forecasts)
  12. 12. Functionality: by overlaying static data (socio economic, flood hazard map) and dynamical data (satellite: TRMM and ECMWF) to produce flood early warning map. Objective: to inform flood potential to stakeholders related to water resources (BBWS/BWS/Dinas) in the context of securing infrastructure from flood hazards Satgas Banjir
  13. 13. Nation Water Weather and Climate Information System 7 wflow hydrological models covering the archipelago, 500 meter resolution
  14. 14. WORKFLOW OF DROUGHT EARLY WARNING SYSTEM This system was developed also for assessment water availability in irrigation weir
  15. 15. INPUT DATA Static Data 1) DEM Geotiff WGS84 (Source : SRTM NASA resolution 90 m) 2) Landuse Geotiff WGS84 (BIG ) 3) Soil type Geotiff WGS84 (Source : FAO, resolution 1:5.000.000) DEM Map We have reclassify landuse map from the existing 17 categories into 6 general classes of landuse We have reclassify soil map from 139 soil type into 8 general soil classes as follows.

  20. 20. Drought Information, Meterological and Hydrological Real time
  21. 21. Water Availability Objective: to inform Natural Discharge on river segments anywhere. Water availability uses hydrological model wflow to determine discharge.
  22. 22. Citarum – Nanjung (Inflow to Saguling Reservoir)
  23. 23. Satgas Kekeringan Drought Unit Team Objective: to inform Hydrological Drought Forecasts to stakeholders related to water resources (BBWS/BWS/Dinas) Satgas kekeringan based on water availability by determining the statistical value of water availability data (Q80, Q90, Q95)
  24. 24. WEBSITE of PSH ❖ Stakeholders/users can see the data and information on web portal but can’t download the data. ❖ Only certain users and administrator can download data. ❖ For users who need the data or more information, they can contact the officer directly or can fill out a data request form. ✓ The address: The PSH website still under development (on localhost) and is expected to be online and publicly accessible later this year (2019). ✓ The planning: to facilitate water resources data and information on R&D results. ✓ Another function is to facilitate data from SI-PSH.
