| Sumario: | A typology of discharge areas on sandy soils in Doñana has been carried out based on the vegetation, groundwater hydrochemistry and water tablc regime. Water table (annual and interannual) fluctuations have been related to the connection with different groundwater flow systerns (local, intermediate and regional). Five types of ponds are proposed largely corresponding to previous classifications: permanent ponds, temporary ponds, ephemcral ponds, "fern" ponds and wet slacks. A hypothesis of the desiccation of cphemeral ponds connccted to intermediate flows is considered |
