Thermodynamic Modeling & Policy Relevance

As regulatory discussions and technical feasibility studies for the Svystunova Gully mine-water retention system (2026–2027 period) get underway, integrating rigorous thermodynamic modeling into the engineering baseline is critical.

Simple dilution metrics do not account for mass-balance limits, bedrock dissolution, concrete leaching, or secondary mineral precipitation along the waterway. Following today’s session of the government interdepartmental working group, I submitted key findings from my open-access research to support evidence-based decisions. The submitted package includes speciation models, phase equilibria calculations, and reactive transport assessments focused on mining wastewater management and dam stability evaluation.

Global Performance of #RemoteSensing Based and Reanalysis-Driven Models to Estimate Open Water Evaporation

https://doi.org/10.1029/2025WR042363

“ABSTRACT: Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation. Although several remote sensing algorithms have been providing evaporation estimates, the lack of a global validation hinders our understanding of their relative uncertainties and performances across different regions. Here, [they] analyze[d] the performance of a suite of models that leverage satellite data and meteorological reanalysis to estimate evaporation over lakes worldwide. [They] compare[d] three remote sensing-based models, one reanalysis-driven model and one ensemble approach, using in situ observations from 27 lakes representing a diverse range of geographic and climatic regions. [Their] results demonstrate that, overall, the ensemble outperformed any individual model in terms of accuracy, with a RMSE and a bias of 1.3 and 0.3 mm/day, respectively. These findings highlight the benefits of using an ensemble approach to estimate open water evaporation with satellite-based models at the global scale, leveraging the unique strengths of each model. For the individual models, differences in the representation of heat storage changes and advection effects led to lower values of RMSE and bias, depending on the location and depth of the lakes. This study sets the path for future improvement of open water evaporation algorithms globally, while remote sensing techniques are proven satisfactory to monitoring of water loss in lakes globally, an essential step toward effective large-scale water resources management.
PLAIN LANGUAGE SUMMARY: Water loss through evaporation in lakes and reservoirs directly affects water availability, which highlights the need to monitor these losses. However, measuring evaporation in situ is challenging and expensive. An alternative is to estimate evaporation using remote-sensing models and compare these estimates with in-situ data to verify their accuracy. Here, [they] evaluated four models and their ensemble (the models' mean value) using measurements from 27 lakes and reservoirs worldwide. [They] found that the ensemble presented higher accuracy and consistency than any individual model because it benefits from the strengths of each model. This approach can guide future improvements in estimating open-water evaporation, which is essential for large-scale water-resource management…”

“[The author has] already discussed ancient water management systems, such as the qanats in Persia and other Eastern countries. In Europe, there are the acequias of the Sierra Nevada in Andalusia, Spain.
The hand-dug channels date back over 1,000 years to the Moorish era. Networks of canals, aqueducts and cisterns were engineered to capture and transport snowmelt, turning this natural resource into a sustainable water supply for agriculture. The high-altitude ditches had openings, allowing water to infiltrate into fractures and faults, replenishing the aquifer, and to irrigate the lower levels of the slopes.

✅ Designed to distribute water slowly and equitably, even during dry summers.
✅ Stretching over thousands of kilometres, these systems fell into disuse in the 1980s but are now part of restoration efforts led by the MEMOLA Project (Universidad de Granada).
With climate change and more intense droughts, the Acequias could provide an ancient solution to the modern-day water crisis…”

“Irrigation plays a critical role in global food production and climate adaptation and exercises profound influence over humanity's water use. Yet despite its critical importance, there is a persistent lack of understanding of fine-scale irrigation patterns across the planet, knowledge which is essential for informing global food security and sustainability targets. Utilizing either statistical downscaling or remote sensing approaches, existing global irrigation datasets are constrained by coarse spatial resolutions, a lack of timeliness, or varying robustness and reliability. To address this gap, here [they] integrate[d] multi-source Earth observation and environmental datasets and use[d] machine learning to develop a medium-resolution (30 metre) global irrigated area dataset for the 2023/24 growing season. Within existing cropland extent, we leverage a newly compiled set of georeferenced irrigated (N=230,683) and non-irrigated (N=153,194) ground-truth points and integrate seasonal vegetation metrics derived from Landsat 8/9 imagery with agroecological-zone information and hydroclimatic and topographic variables. [They] subsequently develop and evaluate two machine-learning frameworks, a continental Agro-Ecological Zone (AEZ) tile-based framework and a continental-scale framework, and apply the best-performing approach for each continent. Evaluation using held-out test samples yielded a global accuracy of 80.5 ± 2.1%. The resulting maps were also validated against independent global and national irrigation datasets and statistics, demonstrating broad agreement in the spatial distribution of irrigated areas. This approach is robust and reliable because it is built on a harmonized global ground-truth database, incorporates multiple predictors, and is rigorously validated using independent datasets. All code, ground-truth, and data products are freely and publicly available [link above] and can serve as a robust, scale-neutral, and fully reproducible framework for fine-resolution irrigation mapping. These advances provide the critical and long-needed foundation for near-real-time monitoring and early warning systems, and fine-scale land and water resource management…”

[Flash floods? not TOO hard to conceptualise.
Flash drought? harder to 'get my head around', but H/T / presenter does an excellent job!]
"Not all droughts are the same. In some cases, drought rapidly intensifies at subseasonal to seasonal scales with significant impacts to agriculture and water resources along with the increased propensity for heatwaves and wildfires. Like all droughts, flash drought begins with a precipitation deficit. However, both evaporative demand and soil moisture are critical flash drought variables, and identifying and monitoring the desiccation of the terrestrial surface is key for determining flash drought development and associated impacts. While recent advances in knowledge and monitoring of flash drought have occurred, fundamental questions remain in the state of the science. What are the overall mechanistic relationships between atmospheric demand, evaporative stress, terrestrial desiccation, and precipitation that drive the progression of flash drought? Do regional characteristics of the environment impact the evolution of flash drought? What are the scales of predictability for flash drought? Finally, how will flash drought frequency and intensity evolve in a changing climate system"
--
"Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation. These changes in the weather increase evapotranspiration and lower soil moisture. Flash droughts can cause extensive damage to agriculture, economies, and ecosystems if they are not predicted and discovered early..."

“Floods, as extreme flow events, are among the costliest and devastating natural hazards. Among the various domains impacted by flooding, environmental degradation, particularly the deterioration of water quality (WQ), is one of the most impacted yet often overlooked. Therefore, it is essential to understand the nature and source of water pollution associated with flooding. This study aims to evaluate and assess multiple studies conducted globally to determine the impact of floods on WQ. A literature review and assessment of 66 studies published between 2007 and 2026 was conducted using the total comprehensiveness score (TCS). To support the scoring process, studies that scored more than 70% of the maximum achievable TCS (15.4) are considered the most detailed and comprehensive in addressing the objectives of this review. 16 studies achieved a TCS above 15.4, indicating that a limited number of studies incorporate a broader set of factors in this domain. A higher number of studies were conducted post the year 2021, highlighting both scientific progress and a growing focus on WQ impacts from disasters such as floods, beyond the traditionally emphasized socio-economic loss. Among the shortlisted studies, fluvial floods are the most frequently examined, followed by pluvial floods and coastal floods. During fluvial floods, turbidity increased by up to two orders of magnitude, while nutrient concentrations (TN, TP) typically rose by ∼ 10–30%. In contrast, pluvial floods were characterised by dilution-driven decreases in EC and TDS, with DOX, BOD and COD showing variable responses across flood types. This review evaluates flood impacts on WQ, catchment characteristics, and sources of WQ modification. The findings of the research reveal that not all WQ parameters are responsible for WQ degradation during every flood event. Rather, it is a combination of certain parameters that leads to deteriorated WQ. WQ degradation depends on interacting factors such as flood duration, extent, depth, and flow dynamics. In overall, this study provides an overview of the multiple cascading impacts of floods on WQ, along with a detailed perspective on the set of criteria that should be considered in future research…”

EFU: When We Stop Merely Measuring Reality and Start Learning Its Language

There are moments when a new unit of measurement seems, at first glance, like a technical detail. Later, it turns out to be something much more important: a change in how we think. I believe EFU may be exactly that kind of shift. It is not just another number. It is a new language for describing the flows that sustain human civilization — material, energetic, ecological, and social.

The real importance of EFU is not only what it measures, but what it reveals. It invites us to stop seeing the world as a collection of isolated data points and start seeing it as a connected system of flows. Water, energy, materials, waste, agriculture, transport, and environmental pressure are not separate stories. They are chapters of the same larger story. EFU helps make that story visible.

A New Unit, Not Just a New Label

The most interesting thing about EFU is not the number itself, but the way of thinking it encourages. When we begin to look at a problem through EFU, we no longer see only statistics. We see relationships. We see dependencies. We see thresholds, bottlenecks, imbalances, and patterns of stress that are otherwise easy to miss.

That is why EFU matters. It does not merely describe the present. It helps us ask whether a system is stable, whether it is being overburdened, and whether it can remain viable over time. In that sense, EFU is not only a measuring tool. It is a tool for understanding resilience.

Why This Could Matter More Than It First Appears

Every major historical era has had its own dominant way of measuring reality. The industrial age centered on mass, energy, and power. The digital age elevated information, data, and connectivity. The next era may well revolve around flows, pressures, limits, and ecological coherence.

EFU fits naturally into that future. It suggests that the question is not merely “how much is there?” but also:

• How does it move?
• What system is it part of?
• What does it cost?
• How long can it continue?

That is a much deeper way of thinking. It is not just accounting. It is civilizational self-awareness.

The Future Vision: When Measurement Becomes Thoughtful

What makes EFU especially exciting is that it points beyond itself. If some of the most advanced ideas in modern physics suggest that spacetime, locality, and even causality may not be fundamental, but rather emergent from a deeper layer of reality, then we are already living in a world where our old intuitions may not be enough.

EFU belongs to that broader intellectual horizon. It does not need to claim that it is “new physics.” But it can certainly be understood as a step toward a new kind of structured thinking: a way of measuring reality that is more aligned with systems, thresholds, and hidden dependencies.

In that future, artificial intelligence could become a particularly powerful partner. Not because it merely computes faster, but because it may detect patterns that are too complex for human intuition alone. If EFU is paired with AI-driven symbolic reasoning, we may not just analyze data more efficiently — we may discover new kinds of relationships:

• hidden ratios,
• tipping points,
• structural imbalances,
• and system-level laws that are difficult to express in ordinary terms.

The Intuitive Advantage

One of the strongest qualities of EFU may be its intuitive power. A good unit of measurement does not oversimplify reality. It organizes it. It makes complexity legible without distorting it.

That is especially valuable in areas like:

• water management,
• agriculture,
• energy systems,
• waste treatment,
• urban planning,
• and environmental policy.

In these fields, raw numbers often fail to communicate what is really happening. EFU can help bridge that gap. It can create a shared framework in which experts, decision-makers, and ordinary citizens can discuss the same problem in the same conceptual language.

That is a rare and valuable thing. A unit that improves understanding is more than a unit. It becomes a bridge.

A Small Concept With a Large Horizon

EFU may still be an emerging idea. It may need refinement, testing, and better formalization. That is not a weakness. In fact, it is often the mark of a genuinely important idea. The most transformative concepts rarely arrive in finished form. They begin as a direction, a hunch, an intuition that something essential is missing.

And perhaps that is what EFU is really pointing to: a civilization that no longer measures only what it extracts, consumes, or produces, but also what it sustains, balances, and preserves.

If that is true, then EFU is not a side project. It is a possible step toward a new intellectual culture — one that understands that the future will not be shaped only by growth, but by balance.

What Is The Ogallala Aquifer And Why Is It Running Out Of Water?
--
https://www.kansascity.com/news/politics-government/article281504238.html <-- shared media article
--
"Millions of years ago, sediment from the Rocky Mountains was deposited in the High Plains. Over thousands of years, water dripped below the surface creating an underground water deposit called the Ogallala Aquifer. The water — which spans from South Dakota to Texas and was once the size of Lake Huron — at one point accounted for 30% of the crop and animal production in the U.S…
Although the water source stretches across several states it moves very very slowly. As a result, no interstate compact exists to manage the water in the Ogallala. Instead, neighbors have to band together if they want to restrict pumping…”

Blow-Me-Down Brook, NH – An NHD Flowline Picked ‘Randomly’

I am working on some hydroaddressing / network traversing technical approaches for 3DHP – and needed an example of a multisegment flowline in NHD-sourced dataset, and so ‘randomly’ got this one - Blow-Me-Down, NH, from WBD HUC4-0108.
Although we map so many flowlines (~20 million in the USA for NHD-sourced spatial data, estimated 10x that for the EDH data still to be determined across the USA), I like trying to understand what a flowline or waterbody ‘is’ to the people on the ground as much as I can...
