Conditions for the application of aquifer recharge:

• Sufficient amount of surface water

• Quality of the surface water and chemical compatibility with that of the groundwater

• Suitable geological conditions (surfaces and subsoil with high permeability, aquifers in sequence and in hydraulic interconnection, etc.)

• Geomorphologically suitable areas

• Construction and operating costs

 

Multi Criteria Decision Analysis (MCDA): designing, evaluating and prioritizing alternative decisions

1. Set the goal/define the problem

2. Determine the criteria

3. Define the criteria values

4. Determine the weight of each factor

5. Aggregate the criteria

6. Validate/verify the result

​

​

The spreading method for aquifer recharge was selected according to the following facts: source of excess water available nearby, relatively flat area, permeable soils and presence of an unconfined aquifer.

​

Four scenarios were examined:

• first scenario only the hydro-geological and geomorphological characteristics were taken into account

• second scenario the distance criterion from the local reservoir was considered

• third scenario the distance criterion to the river that crosses the basin was considered

• fourth scenario both criteria, distance to the reservoir and the river were considered
