Water quality monitoring in the lagoon level shows fluctuation of salinity from 2 ppt to 33 ppt. Opening of barmouth during rainy season allows salt water intrusion in the later part of rainy season. That might be the direct cause for the salinity level in the lagoon. So what are the options and remedies for salinity problem to include during the preparation of water quality management plan?
There is no clear agreement about what constitutes best management practice for salinity . While there are a range of techniques and strategies available, success is often varied from one context to the next; there is no simple solution. Location, time frame and personal circumstances may all influence the effectiveness of particular options.
Possible management strategies include:
The use of salt-tolerant plants, such as:
. Atriplex amnicola
.Saltgrow - a hybrid gum tree being utilized within Australia to try to reverse damage within affected high-salinity areas. The tree has been highly successful, and has been attributed to be able to completely remove salinity within damaged areas and allowed new grasses and shrubs that are not salt resistant, to grow.
.The use of perennial crops and pastures
. Engineering responses including deep drainage and pumping (to lower groundwater)
. Reverse banks and interceptor banks (to divert surface water)
.Revegetation with native species
. Establishing trees
.Preventing further clearing in vulnerable areas
