Multi Purpose Water Storage

DISCLAIMER — Four Real Technologies, One Undemonstrated Combination, No Framework Bridge

Why no UTAC/CREP/AFET bridge: not only because the cited literature already provides the necessary quantitative structure -- a deliberate choice. This project's highly speculative AFET/UTAC experiments must never stand in the way of climate/ecology topics being accessible and usable to people who don't work inside that construct and aren't looking for renormalization groups. Real, checkable science, without the burden of an unproven framework. See PACKAGE_REGISTRY.md's "Why no UTAC/CREP/AFET bridge in the climate/ecology series" (2026-08-31) in the GenesisAeon workspace root for the full canonical note.

Status: Real, independently verified science and real institutional monitoring data for four separate pieces; an honest, explicit non-finding for their combination. NO UTAC/CREP/AFET bridge.

What this is

Every academic citation was checked directly against the paper/DOI on 2026-08-16; the ATES deployment figures are aggregated from Dutch water-research institute monitoring (KWR, Deltares), not one peer-reviewed paper, and are labeled "documented tier" accordingly.

multi-purpose-water-storage-utac

GenesisAeon Package 112 — can one basin do it all? Grew out of a direct question during a conversation: if we build large artificial water basins (see glacier-buffer-replacement-utac, P100's AGBR reservoirs), could the same basins also generate power, store heat, and feed local wetlands and inland-waterway navigation channels? This package documents four real, independently quantified pieces of that question — then honestly documents what a dedicated search for a real INTEGRATED system actually found. Deliberately has no UTAC/CREP/AFET bridge — see DISCLAIMER.md.

For a plain-language explanation of the same topic (German, no jargon, written for general audiences), see WHITEPAPER.md.

Deliberately not one-sided

The navigation-weir module directly complicates the intuitive expectation that motivated this package: does_navigation_infrastructure_reconnect_wetlands_by_default() returns False — real, basin-wide Danube data shows navigation infrastructure disconnects wetlands by default (−68% floodplain extent vs. pre-regulation), not feeds them. And the closing module, is_integrated_system_literature_documented() (also False), is paired with absence_of_evidence_means_impossible() (also False) to make explicit that "not found in the literature" is a much weaker claim than "impossible."
