“… [The authors] analysed one year of drip water monitoring data from 46 monitoring sites across six karst regions in southeastern Australia. By integrating fast Fourier analysis, cross-wavelet transform and change point analysis, [they] identified five characteristic recharge behaviours and developed a conceptual framework linking temporal drip dynamics with recharge mechanisms. [They] hope this framework will contribute to a better understanding of recharge heterogeneity in karst systems and support future groundwater research under a changing climate…”

Three new papers using caves as hydrological observatories

A short post, highlighting three papers published in recent weeks that I have had the fortune of contributing to. All use networks of drip loggers in caves to record water movement from the surface to the water table.

First, led by Akhilesh Kumar at UNSW Sydney, is a satellite remote sensing study. Can we use satellite-derived products, such as rainfall, vegetation characteristics and soil moisture, to understand when recharge events might occur? Using a network of cave drip loggers in SE Australia, the paper ‘Investigating correlative & causal drivers of precipitation-driven groundwater recharge occurrences in southeastern Australia’ gives the answer. Find out more here (Open Access) in the Journal of Hydrology: Regional Studies.

Second, led by Kashif Mahmud and Rowann Remie at Midwestern State University in the USA, uses another network of cave drip loggers, this time distributed throughout Natural Bridge Caves in Texas. The paper, ‘Heterogeneity of karst water movement revealed through cave drip hydrology’, tackles the question of the controls on water movement in karstified limestone. What is more important control on the variability of water movement – depth below surface, geology, or something else? You can read more here (Open Access) in Frontiers in Water.

Third, led by Danyang Sun at UNSW Sydney, uses time series analyses to conceptualise water movement in karstified limestones using a network of drip loggers in SE Australia. Her paper, ‘Classification and Conceptualization of Karst Recharge Processes Through Spectral and Change Point Analysis of Drip Water Dynamics’ is just published in the journal Water Resources Research, and you can read it here (Open Access).

An 18-foot-deep well in Gujarat's Morbi district has drawn crowds after producing continuous waves for days. Experts say the phenomenon is linked to groundwater recharge and trapped air, not seismic activity. https://english.mathrubhumi.com/news/india/morbi-gujarat-well-mysterious-water-waves-kp6h9lnh?utm_source=dlvr.it&utm_medium=mastodon #Morbi #Gujarat #Well #Groundwater #WaterWaves

#Navajos and #Hopis Formally Oppose Pumped Storage Proposal Targeting #BlackMesa

Flagstaff, AZ - " #TóNizhóníÁní, #Diné Citizens Against Ruining our Environment (#DinéCARE), #BlackMesaTrust and the @centerforbiodiv have filed motions to intervene urging the
Federal Energy Regulatory Commission to deny the preliminary permit application for the #Chilchinbeto Pumped Storage project southeast of #Kayenta on the Navajo Nation

" 'This wildly unrealistic project would only add to decades of harm from coal mining to Black Mesa’s people, land and aquifers,' said Nicole Horseherder, executive director of Tó Nizhóní Ání. 'Asking for federal approval when the application is riddled with incomplete, misleading and infeasible information is the height of arrogance. It tells us all we need to know.'

"The proposed #ChilchinbetoPumpedStorage project would construct two reservoirs, containing 10,000 acre-feet each of water, one on the rim of Black Mesa and the other 1,500 feet below in the valley. The water to fill the reservoirs would come from either the aquifer deep beneath Black Mesa or the San Juan River, according to the application submitted by the company Nature and People First. After the initial 10,000 acre-feet to fill the reservoirs, the project would require withdrawing an estimated 2,500 acre-feet every year to keep them full.

" 'Like coal mining before, this proposal would require rural communities to sacrifice more land and water so that electricity and profits can be exported to faraway cities,' said Robyn Jackson, executive director of Diné C.A.R.E. 'This isn’t something we want or need, and it’s not a history we’ll tolerate repeating.'

"The groups’ motion cites problems relating to industrializing Black Mesa and its #groundwater, including impacts to local communities and families, depletion of rivers, groundwater, and springs, and impacts to wildlife and their habitat. It cites the applicants’ failure to consult with the #HopiTribe, failure to consider water use in the context of regional drying, and their mischaracterization of support from the #NavajoNation’s Resources and Development Committee. It details incomplete, misleading, and infeasible aspects of the proposed project and calls for affected communities to participate in any further study development."

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

https://doi.org/10.1111/gwat.70092 <-- shared paper

H/T @thomas Wöhling | Professor at TU Dresden
“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...”

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...”

“[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.

" U.S. Bureau of Land Management leaves Monterey County open to potential oil and #gas leases.
...
"There are almost 500 idle wells in #MontereyCounty – wells that are no longer productive but can still leak #oil and #pollutants – 97 percent of which are located above #groundwater sources.”
