  3. Primary data Collection Satellite map, maps (topo,soil…) Meteorological data Bibliography Socio-economic data Hydrogeologic data Analysis and data Processing Geographic Information Conception WaterWare system IMPLEMENTATION OF RRM & WRM METHODOLOGY

  4. Case Study • Water use • Domestic • Industry • Agriculture Melian basin Increase • Area = 553Km² • Population = 481 960 inhabitants • 4 subcatchments • Dense Drainage network Noeuds • Barrages: El H’ma • 26 mountains lakes • 2500 wells Aquifer • Lithology = plio-quaternary • Groundwater storage = 27.31 MCM/ year • Exploitation = 28.1 MCM / year • Nbre of Bore hole = 494 • State = overexploitated Case study: Melian basin, TUNISIA

  5. PRODUCTS / REALIZATION • A geographic database • 40 vector layers • 6 raster data • 2 land use maps • Hydrogeologic, Hydrologic and Climatologic database in order to determine the: • Hydrological characteristics • Hydrogeological characteristics Input of WaterWare

  6. Geographic database • Soil map • Hydrographic map • Topographicmap • Geologic map • Soil Type • Contour line, road network • Railway, bench mark… • Lithology, tectonic Thematic map Corine land cover Landuse map (1988 & 2000) Land use map • Aerial photos 2000 • Spot image 1988

  7. Hydrography Elevation 0-77m 77-155m 155-233m 233-311m 311-389m 389-467m 467-545m 545-622m 622-700m Hydrologic study of the catchment areas Catchment geometry Catchment relief Drainage network Water inflow in the catchments Digital Elevation Model of the drainage basin of Melian

  13. Index of Areas changes

  14. Hydrogeologic Information System Hydrologic data Hydrogeologic data Environmental data Meteorological data • Characteristics of 2460 Well • Treatment station plant Generality of STEP Affluents STEP Effluents STEP • Climat data: Temperature Rainfall Wind Evaporation • Management of the catchments area • Hydrogeologic characteristics of the Groundwater • Management of the regions • Determination of the hydrologic characteristics • Dams and lakes characteristics • Calculate the inflow Water in each Catchment Hydrogeologic Information System(HIS)

  15. GIS data Environmental data Meteorological data Hydrogeologic data Hydrologic data Main interface of the HIS

  16. Interest of the Hydrogeologic Information System • A Data Bank with a maximum of data about region’s feature (hydrological, hydrogeological, environmental, meteorological, soil, GIS data…) • Regroup and organize data in the same frame. The scatting of the hydrogeological data about the catchment area will be a hurdle behind researches • We can manage a SHP files without using ArcView • Simulation of water inflow in the catchment • Conception allowing making additions of new frames and modules • Update will be very easy since data will be centralized

  17. WATERWARE MODELS (RRM & WRM)

  18. RAINFALL/RUNOFF MODEL(RRM)

  19. Implementation of RRM model

  20. Parameters of RRM model

  21. Elevation distribution (area/elevation)

  22. Land use distribution

  23. Results of RRM

  24. Results of RRM

  25. Results of RRM

  26. WATER RESSOURCE MANAGEMENT MODEL(WRM)

  27. Water nodes • Collection of 2500 wells built in the case study: complete information is available concerning: wells depth, diameter, usage, exploitation, equipment, standing water level, dry residue… • Dams: name, coordinates , sector, year of construction, storage capacity, irrigated area, inflow water, name of catchment… • Collection of historic data related to observation wells in the groundwater • Mountains Lakes: name, coordinates, realization year, name of catchment, area of the catchment, storage capacity, delegation… • Observation well: name, coordinates, year, dry residue, standing water level… • Collection of hydrologic, hydrogeologic and meteorologic data

  28. WaterWare nodes chart

  32. Irrigation node

  33. Diversion node

  34. Results of WRM

  35. Results of WRM

  36. Planned Work • Refinement and updating of GIS data base • Try to run the WRM model with new time series collected from stakholders • Identification and analysis of indicators (physical & economic) and investigation of water quality related impacts • Optimisation scenarios • WP04 Water Technologies • Dissemination of experience and results on the local and international scales.

  37. CONCLUSIONS Realized works: • Geographic database • 40 layers SHP and 6 raster data • Two Land use map (1988 & 2000) • Land Use Change map • Hydrogeological database • Information about 2460 wells (depht, standing water level, salinity,…) • Information about the groundwater (phreatic and profond) • Information about nodes: • Lake, dam… • Observation well, bore hole… • Vectors layers and raster data technicalreport • Hydrological technical report • Determination of the inputs user in WaterWare

  38. Realized works: • Establish the Stakholders database • Topologic model of the basin has been identified • Implementation of RRM and WRM model • GIS data sent to NCRS • Stakeholders Workshop
