Artificial Recharge Advantages And Disadvantages

2.5.3 Full scale project implementation

Test programme results are used to recommend final, full scale programme parameters, including sites for additional wells or infiltration ponds (if necessary), potential future options for sourcing of surface water, planning of recharge management during regular operations, and necessary monitoring. Focus is kept on keeping the system design flexible, so that changing needs of the client can be integrated with existing recharge operations and facilities.

2.8.3 HYDRUALIC CONDUCTIVITY (K)

Hydraulic conductivity is a measure of how easily water can pass through soil or rock: high values indicate permeable material through which water can pass easily; low values indicate that the material is less permeable. Hydraulic conductivity is typically given the symbol k and has units of velocity, for example meters/sec or meters/day.

It is also important to realise that the way that a fluid (such as water) passes through a soil or rock mass depends not only on the properties of the soil/rock but also on the properties of the permeating fluid. This means that a given soil or rock will behave differently if it is permeated by different fluids – for example water or hydrocarbons (oil).

Even when dealing solely with water as the permeating fluid, the properties of water can have an influence. The viscosity of water varies with temperature, so hydraulic conductivity will also vary with temperature. However, in most cases the range of temperature variations in geotechnical problems is small enough that any resulting changes in hydraulic conductivity can reasonably be neglected. { Preene Groundwater Consulting
