The project

Scientific AI, designed to move with the water.

Water research rarely fits inside one dataset or one model. RAIN is built around the relationships between them: observations and simulations, local measurements and system-scale behavior, fast AI inference and physical understanding.

A U.S. Department of Energy-led national initiative

RAIN and the Genesis Mission

The Genesis Mission is led by the U.S. Department of Energy and its 17 National Laboratories. Project RAIN is led by EnviTrace and funded by DOE through the Genesis Mission, joining a national effort to connect scientific data, advanced computing, experimental facilities, and AI.

01

Connect the evidence

Bring monitoring data, spatial context, and model output into one traceable scientific view.

02

Disentangle Relationships

Use information theory and unsupervised ML to tease apart nonlinear, complex interdependencies while respecting the full descriptive power of the data.

03

Respect the physics

Use physical constraints to guide learning, expose implausible results, and focus computation where it matters.

04

Make uncertainty useful

Turn uncertainty from a footnote into an explicit part of research questions, comparisons, and decisions.

Project partners

Built across institutions and disciplines.

RAIN is being led by EnviTrace and developed in collaboration with national-laboratory and university collaborators whose expertise spans water science, subsurface-system modeling, scientific computing, and artificial intelligence.

Scientific foundation

From drought signals to coupled water systems.

RAIN builds on an established technical lineage of interpretable AI for water science. In a 2022 study co-authored by EnviTrace CTO Velimir Vesselinov, researchers combined climate projections, a process-based hydrologic model, and NMFk to reveal spatial and seasonal drought patterns across 134 Colorado River Basin subwatersheds.

The study showed how AI can extract interpretable spatial and temporal patterns that researchers can relate to physical processes, while keeping differences between climate scenarios visible. RAIN carries those principles forward—from regional surface-water analysis to integrated research on coupled surface-water and subsurface systems, using observations, physical models, advanced computing, and explicit uncertainty.

Figure 2 · From data to patterns

NMFk organizes 134 subwatershed time series into a matrix, extracts shared signals, and maps watersheds with similar behavior—the paper's clearest example of moving from raw model output to interpretable structure.

Figure 6 · Where patterns change

Spatial clusters compare historical and future dry-day behavior, plus the delta between them, under dry and wet scenarios. Blank panels indicate that NMFk found no acceptable solution; colors identify separate clusters within each panel and should not be compared across panels.

Figure 7 · When patterns change

Seasonal dry-day signals correspond to the spatial clusters in Figure 6. Individual lines represent subwatersheds and dashed lines mark cluster medians, making the timing and scenario dependence of those patterns visible.
