| 3.2 | Definitions |
| Baseflow | is a sustained low flow in rivers during dry or fair weather conditions, but not necessarily all contributed by groundwater; includes contribution from delayed interflow and groundwater discharge. |
| EWR | refers to the flow patterns (magnitude, timing and duration) and water quality needed to maintain a riverine ecosystem in a particular condition. |
| Recharge | is the addition of water to the zone of saturation, either by downward percolation of precipitation or surface water and/or the lateral migration of groundwater from adjacent aquifers. |
| Reserve | is the quantity and quality of water required to satisfy the basic human needs by securing a basic water supply and to protect the aquatic ecosystem in order to secure ecologically sustainable development and use of the relevant water resource. |
