All point sources of relevant nutrient have to be measured to find the total nutrient load that sometimes amounts to an overload and nutrient pollution.

Fresh water with bonded nutrient from Aus east coast town and city sewage dumping flows northwards and that of it not taken up en route flows into GBR waters and beyond.
Alongshore current energy to move the flow is strong enough to transport heavy sand northwards to Frazer Island where the sand falls over the Continental Shelf. But the fresher surface water with bonded nutrient continues northwards inside the GBR lagoon reaching Cape York.
Other point source nutrient is added along the way.

Here is the sediment dispersal system involved.

JF Aus while I understand nutrient pollution you know much more than me it seems we can both only hope in time we start looking after our environment and stop having the wool pulled over our eyes by the self interests of the few

Keep in mind that irrigation has its downside too, if not managed properly it leads to degradation of the soil; currently some 20% of Australia's irrigation areas is badly affected by salinity.

Evidence of substance indicates that when the human activity-linked cause of change to underwater El Nino and La Nina phenomena and association with severe weather is scientifically understood, it will be possible to understand and manage restoration of natural and very predictable weather.
Correct prediction of weather can amount to drought proofing for farmingb.

Natural weather has not caused soil worldwide to be excessively salty.

Ocean and lake algae plant matter and associated warmth linked to precipitation are presently not included in established meteorology.

Regarding any of the above, what science proves otherwise?

Both posts are well said Is Mise the salty water is because of both use of underground water and that water rising because of misuse and rising water table our water as I propose may in fact add to or stop that problem but first we need to get the water there consideration of what to grow to help that problem must be given,we if we turned this water inland and as a result grew trees as well, we could bring about more rainfall

irrigation has its downside too,
Is Mise,
Yes, but what we're advocating is to bring freshwater into the periodically drought affected areas & even more importantly, recharge the groundwater which has been used up to the point of no water left to pump. Redirecting the monsoonal flood waters from the north via their natural channels to the south is a no brainer. All it needs is a will by Governments to prolong that flow. Which major party has the sense to start such a project & which minor parties have the sense to support it instead of standard ideological sabotage ?
As I stated previously, such a project is a long term one with long term investment involving all for a long term benefit to all.
