Here we introduce a high-resolution physics-embedded big-data-trained model as a breakthrough in reliably capturing characteristic hydrologic response patterns ('signatures') and their shifts. By realistically representing the long-term water balance, the model revealed widespread shifts - up to ~20% over 20 years - in fundamental green-blue-water partitioning ","authors_text":"Ather Abbas, Chaopeng Shen, Farshid Rahmani, Haoyu Ji, Hylke Beck, Jiangtao Liu, Kathryn Lawson, Ming Pan, Tadd Bindas, Yalan Song, Yoshihide Wada, Yuan Yang","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.geo-ph","submitted_at":"2025-04-14T20:58:52Z","title":"Distinct hydrologic response patterns and trends worldwide revealed by physics-embedded learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.10707","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:1521102008c5632a023afe3c30b2bdb841e4331656c344d6d1d0cdbf2aa2e249","target":"record","created_at":"2026-07-05T10:52:40Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"9f3c605dbaf6f0a47486ec848e1b4da3d48e2d14aa72df6767aad9a82d7cdf27","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.geo-ph","submitted_at":"2025-04-14T20:58:52Z","title_canon_sha256":"4ab70cd95aa52b45f7502e5f5bf8d0deb415a9699b8dfab7e5dffe9624af8c26"},"schema_version":"1.0","source":{"id":"2504.10707","kind":"arxiv","version":2}},"canonical_sha256":"b9d492dd6ac9de21aaad10719d595a93890c09db64c89a0270c08e4be79d6841","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b9d492dd6ac9de21aaad10719d595a93890c09db64c89a0270c08e4be79d6841","first_computed_at":"2026-07-05T10:52:40.416143Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:52:40.416143Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4ab8VboE5qzn7DPP6/c3mQVT06oX2a8Q7TMhB7K55M03gkWxlVrpDHn6RfotSYa4bVswUM6ynJJHPXut1NRYDg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:52:40.416650Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.10707","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1521102008c5632a023afe3c30b2bdb841e4331656c344d6d1d0cdbf2aa2e249","sha256:374cafb1e1e71c8a4c3f7f481d773853bf8d7d4367f28e03b6697065136fc176"],"state_sha256":"4e27507a4f7dd4a0e30eabe48c3a0bc276509b6df4ce1f9d1f0379a0172e1cf2"}
