Water Table Monitoring (WTM)
Long term groundwater monitoring aims to detect groundwater trends that may be attributable to land use change or the adoption of certain land management practices. It is sometimes difficult to make an assessment, even with more than five years of data. On top of this, there have been abnormal climatic events to account for, such as the extended dry period experienced since the mid to late 1990s.
Erosion and Sediment Control
The three cornerstones of the erosion and sediment control industry are drainage control, erosion control, and sediment control. The functions of construction phase drainage, erosion, and sediment controls are presented below.
* Drainage control measures aim to prevent or reduce soil erosion caused by concentrated flows (including the management of rill and gully erosion), and to appropriately manage the movement of "clean" and "dirty" water through the site.
* Erosion control measures aim to prevent or reduce soil erosion caused by raindrop impact and sheet flow (i.e. the control of splash and sheet erosion).
* Sediment control measures aim to trap and retain sediment displaced by up-slope erosion processes.
