Headwater Flow & Storage
This site is a controllable headwater system.
It sits at the point where rainfall becomes flow.
The question is not what the site is.
The question is whether changing how water moves through this point makes a measurable difference downstream.
What matters
The site receives ~126 million litres of rainfall annually.
At present, that water is moved rapidly through artificial drainage.
This reduces:
time in the ground
interaction with soil and geology
natural storage
The result is fast transfer of water into the wider catchment.
The decision point
There is a clear intervention available:
Reduce artificial drainage influence.
This does not introduce a new system.
It removes the mechanism that is currently accelerating water movement.
What this enables
This creates a measurable before-and-after condition.
Changes can be observed in:
how quickly water moves after rainfall
how long water is retained in the land
how stable baseflow becomes
how water interacts with soil and geology before leaving the site
This is a real system, not a model.
Why this is relevant
Headwater behaviour determines how water enters the catchment.
If water leaves too quickly:
flow becomes more variable
transport of sediment and nutrients increases
downstream systems carry more load
If water is retained and released more gradually:
flow is moderated
storage increases
interaction improves before water enters the wider system
This site is one of the points where that difference is set.
What this offers
This site offers:
a defined input (rainfall)
a known constraint (drainage)
a controlled intervention (removal of acceleration)
observable system behaviour
That combination allows direct measurement of change.
The question
Does changing headwater behaviour at this scale measurably influence:
flow
storage
and water condition
before it reaches the wider catchment?
Engagement
This is not presented as a solution.
It is a system where the effect of change can be measured.
We are seeking alignment on:
whether this type of site is useful
what should be measured
and how it fits within existing catchment approaches
