Shallow aquifer (13)
| Limited aquifers in unconsolidated material of eluvial character (regolith) with shallow groundwater for local use providing variable amount of groundwater based on thickness of aquifers and local recharge values |
Aquifer type (15)
| Moderately productive regional aquifers – T (1–10] m2/d, q (0.01–1] l/s.m, Q (0.5–5] l/s for wells and/or springs – or locally highly productive aquifers in which flow is mainly intergranular |
| Moderately productive regional aquifers – T (1–10] m2/d, q (0.01–1] l/s.m, Q (0.5–5] l/s for wells and/or springs – or locally highly productive aquifers in which flow is mainly through regularly developed system of fissures and joints of sedimentary and volcanic rocks |
| Low productive fissured regional aquifers – T [0.1–1] m2/d, q [0.001–0.01] l/s.m, Q [0.05–0.5] l/s for wells and/or springs – in which flow is mainly developed in irregular system of fissures and weathered mantle of metamorphic and igneous rocks – hard rocks |
| Aquitards – Minor aquifers with local and limited groundwater resources – T < 0.1m2/d, q < 0.001 l/s.m, Q < 0.05 l/s |
| Limited aquifers in unconsolidated material of eluvial character (regolith) with shallow groundwater for local use providing variable amount of groundwater based on thickness of aquifers and local recharge values |
