Groundwater recharge is an important process for sustainable groundwater management, since the volume-rate abstracted from an aquifer in the long term should be less than or equal to the volume-rate that is recharged. Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system.
Various geotechnical engineering methods can be used for ground improvement, including reinforcement geosynthetics such as geocells and geogrids, which disperse loads over a larger area, increasing the soil's load-bearing capacity. Through these methods, geotechnical engineers can reduce direct and long-term costs.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] ...
A spreading ground is a water conservation facility that retains surface water long enough for it to percolate into the soil. Spreading grounds must be located where underlying soils are permeable and connected to a target aquifer . [ 1 ]
In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to investment making land more usable by humans. For accounting purposes it refers to any variety of projects that increase the value of the process. Most are depreciable, but some land improvements are not able to be ...
Deep cement mixing (DCM) is a geotechnical engineering deep foundation ground improvement technique where a binder material, typically cement, is injected into the ground for ground stabilisation and land reclamation. The technique can also be used for containing contaminants and water cut-off. [1]
Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface.
Underpinning may be necessary for a variety of reasons: The original foundation isn't strong or stable enough. The usage of the structure has changed. The properties of the soil supporting the foundation may have changed (possibly through subsidence) or were mischaracterized during design.
