2 IDI Introduction and Session Agenda Dr. Ali Chavoshian, IDI Secretariat, UNESCO/RCUWM-Tehran Recent Drought and Drought Prediction System Development in Korea Prof. Deg-Hyo, Bae, Sejong University, Seoul, Korea Towards Monitoring and Prediction of Severe Droughts by Integrating Numerical Simulation and Satellite Observation Dr. Yohei Sawada, Department of Civil Engineering, University of Tokyo Economic Impact of Drought on Balanced Development of Pakistan: Inter-disciplinary Approach of Drought Risk Assessment Prof. Muneta Yokomatsu, DPRI, Kyoto University Conclusion and Session Wrap-up Dr. Ali Chavoshian, IDI Secretariat, UNESCO/RCUWM-Tehran

3 From correct data to right action Insufficient ground-based observation QC and data accuracy Standard format Commercialism Centralization vs de-centralization Sharing data Demonstration Case Studies

4 Prediction and Monitoring Drought Limitations of relying on only one aspect of drought e.g. meteorological data alone => composite drought indicators Make better use of new data/information e.g. satellite information, ground based weather radar etc. Understanding drought and quantifying drought risk Information from pre-instrumental, instrumental and climate model data Economic impact of drought and inter-disciplinary approach Coping with drought improving resilience Strategies that are robust and efficient under a wide range of plausible futures over short, medium and long time horizons

5 General information of meteorological station (e.g. location and type) Rainfall (mm) General information of climatological stations (e.g. location and type) 1-Climatology Air temperature (Degree) Evaporation (mm) (additional request) Sunshine hour (hours) Average wind velocity (m/s) Relative humidity (%) River discharge 2-Hydrology and Water Quality River Water quality (Province, St. Code, River, Station, From year, To year, class, Na, SAR, msum.k, K, Na, Mg, Ca, Sum.A, So4, Cl, Hco3, Co3, PH, EC, TDS, Temperature, Scale, Discharge, Year, Month, Day, Year- B, Month-, day- B, star_tds, star_all) Sedimentation (Province, CODE, RIVER, STATION, From year, To year, Current type, Sample name, Sediment, CF, CM, Discharge, SHIFT, Year, Month, Day, Temperature) Lake water level

6 3-Geology Surface geology Subsurface geology, Geological Profile, Geological Histogram DEM Lake bed elevation (DEM) or bathymetry data Lake H-V 4-Topography River cross section, Surveyed result (Horizontal, Cross Section and Longitudinal) Topological map 1/250,000 Topological map 1/50,000 Topological map 1/25,000 5-Land use 6-Natural condition and Environment Land use classification maps Information on land use change River, Lake, etc.

7 Observed data (Inflow, outflow, water level and storage volume) Operation rule 7-Dams Physical Conditions (Locations, Dam name, Reservoir Volume(Gross, Effective and dead), Water levels(natural water level, low water level and Flood control level), Purpose of Dam, Dam type(earth, rock fill or concrete), Stage( Operation, Construction or planning), Dam Height, Basin area, Water demand and its purpose), H-V curve, Discharge Capacities) Location of intake point (weir or head work) on maps or GIS 8-Intake facility 9-Groundwater Water amount permitted by water right (or Planned water intake amount) Actual water intake amount Information of service area for water supply(location, area and annual schedule) Location of drainage point Distribution and drainage channel networks (GIS or Map data) Location of observation well Record of water level as long as possible Record of groundwater use amount (village/district level) Pumping test result Drilling test result Groundwater level contour Distribution of salinization

8 10-Water Demand 11-Socio-economic 12-Irrigation/ Drainage Calculated Water Demand and actual water use amount Cnsus data General conditions Actual schemes Irrigation sector Industrial sector Commerce sector Domestic water sector Population change Change in industrial production Change in cropping area General information of irrigation schemes -Location -Area -Administrator -Types and number of working staff and equipment -Water source (groundwater or surface water) -Field water requirement by area and crop -Irrigation efficiency (conveyance and application efficiencies) -Cropping type (double cropping, etc.) -Cropping pattern (monthly level) -Irrigation schedule (Scheme and field levels)
