  1. What piece of shite to start the day on social media with. I ask you, what kind of #Grifting brainless entrepreneur would think that there is any sense in sucking up 40,000 megaliters of #water a year from an #aquifer in one of the driest parts of the land on the driest #Continent on earth to stand up an **Intensive** #horticulture business there?

    We haven’t seen anything as brainless as this since the Ord River Scheme and cotton industries up North in WA. What kind of madperson even think it is a responsible thing to do? The people behind *Future Agribusiness* are nothing but #NeoLiberal predators looking to profit while raping the land. They don’t give a toss about *Country* and the fragile *ecosystems* on land *Never Ceded* . But I do. In fact, the mojority of this society does care about the land and what is bieng done to it in the name of #NeoLiberalism and #NeoColonialism.

    Where is our *Environmental Protection Agency* in all this? Recovering from #Labor Govt death blows no doubt. There is no coming back from this kind of #pillage. Good grief, this is just insane. Here’s hoping the Courts (in reflecting the will of the broader society while adjuticating) will see true justice (in #fascist NT) applied to the benefit of all and not just a few madhats looking to cash up.

  2. Impact of River Morphology on River–Groundwater Exchange in Braided River Systems

    “Do you like braided rivers? We think they are soooo beautiful. And they are interesting to study as well. Particularly how these complex and transient systems interact with regional aquifers…”

    “Coupled models of two braided rivers with real, pre- and postflood event morphologies are studied for river–groundwater exchange changes…”

    “Braided river systems are an important source for groundwater recharge, but their complex morphology makes river–groundwater exchange fluxes difficult to estimate. Their river channel morphology changes frequently after floods, which has effects on recharge rates that have rarely been studied in the past. This work aims to isolate the effects of changes in braided river morphology on groundwater recharge for two sections of the Wairau River and Waikirikiri River in New Zealand. For each study site, two different river morphology variants of a fully coupled surface water–groundwater model utilizing high-resolution DEMs of river bathymetry before and after a major flood event were set up while keeping parameterization and boundary conditions the same. The models demonstrate that flood-induced morphology changes in braided river systems alter groundwater recharge. [They] identif[ied] features, both simulated and observed, that explain the direction of change. Features that increase groundwater recharge are a larger braidplain aquifer extent and volume, larger wetted area and, specifically, an increase of areas with high exchange rates in locations of larger gradients between braidplain aquifer and regional aquifer. These factors influence groundwater recharge independent of connection (Wairau River) or disconnection (Waikirikiri River) of the system to the regional aquifer, albeit with different magnitudes. An extension of [their] research to other braided rivers is needed to more broadly generalize [their] findings...”

  3. 🌎 Mapping dominant chemical speciation in a polluted carbonate aquifer

    In my recent modeling work, I modeled the dominant forms of element speciation in groundwater within a carbonate system.

    Beyond pure geochemical curiosity, this approach provides a practical lens:
    – it reveals where mineral precipitation is most probable,
    – and helps identify zones where remediation can be most effective.

    💻 Combining thermodynamic modeling (PHREEQC) with spatial analysis in R and QGIS turns subsurface processes into actionable insights for water-quality management and contamination mitigation.

    Two figures below show the modeled distribution of cadmium species across the aquifer and their evolution with dilution

  4. 'It will poison everything.' #NativeAmericans protest #YuccaMountain #Nuclear Waste site

    by Ed Komenda, May 22, 2019

    "“Those transportation routes go through any number of sensitive habitats where a #derailment or a truck accident could cause significant impacts on water or on wildlife that live along those transportation corridors,' Donnelly [Nevada state director for the Center for Biological Diversity] said.

    "The office of #Nevada Attorney General Aaron Ford identified the complexity of waste transport as one of many reasons storing nuclear waste at Yucca Mountain does little to protect the #environment and people. Other concerns include national security (waste shipments as terrorist targets) and geology (Yucca's aquifer drains to the #AmargosaValley – home to more than 1,400 people and several #endangered species). [And is seismically unstable]

    "'#Contamination from Yucca Mountain could very easily contaminate the #aquifer,' Donnelly said, 'and thus contaminate all sorts of springs that harbor some kind of endemic life.'"
