🔍 Understanding the Relationship Between "Natural" Aquifer Flow and Pumping Rates 🌊 The interaction between the natural flow of groundwater and pumping rates is crucial for effective water resource management. Here are the key points to consider: 1. Natural Aquifer Flow: This refers to the amount of water that naturally flows through aquifers without human intervention, feeding rivers, lakes, and other discharge areas. It's influenced by: Natural recharge (infiltration from precipitation, snowmelt, etc.) Aquifer permeability Natural hydraulic gradients Storage capacity (storage coefficient) 2. Pumping Rates: This is the volume of water extracted artificially through wells. Pumping creates a cone of depression around the well, impacting the aquifer's behavior. Key factors include: Well capacity (diameter, depth) Aquifer thickness and permeability Pump power Distance from aquifers 3. Relationship: If pumping rates are less than natural flow, aquifers can sustainably provide water. If pumping equals natural flow, the aquifer reaches equilibrium. If pumping exceeds natural flow, it leads to depletion, increased drawdown, and potential risks like saline intrusion in coastal areas. 4. Hydrological Balance: To ensure sustainable water resource management, it's essential to calculate the hydrological balance.... 🌍💧 #WaterManagement #Aquifers #Hydrology #Sustainability #Groundwater #WaterResources #EnvironmentalScience

A hydrological map is an important tool that shows information about surface and groundwater in a given area, including rivers, lakes, valleys, watersheds, and drainage networks. Helps avoid building in areas prone to flooding or landslides. Supports water resource planning and management efforts for sustainability. Helps identify surface and groundwater sources and distribution. #dataVisualization #gis #Hydrology

“Snowmelt drives a large portion of streamflow in many mountain areas of the world” Flow paths from snowmelt to the streams have been conceptualized for decades and its many processes, uncertainties, and future applications are still being examined and hypothesized, with newly discovered findings still emerging almost a century after the groundbreaking work of Horton and others. New data for an old issue are always welcome … Recent work analyzed the influence of snowmelt on spring streamflow (May and June) with different snow accumulation and durations, in an alpine catchment of the central Spanish Pyrenees. Typical hydrometric data including piezometric values, water temperature, electrical conductivity and isotope data (δ18O) were used to better understand hydrological functioning of the basin during these months. Results of the water balance calculations showed that snow represented on average 73% of the water available for streamflow in May and June while precipitation during these months accounted for only 27%.  Rainfall during the melting period was important to determine the shape of the spring hydrographs. On average, 78% of the sum of both the snow water equivalent (SWE) accumulated at the beginning of May and the precipitation in May and June converted into runoff during the May–June melting period. The average evaporation-sublimation during the 2 months corresponded to 8.4% of the accumulated SWE and rainfall, so that only a small part of the water input was ultimately available for soil and groundwater storage. When snow cover disappeared from the catchment, soil water storage and streamflow showed a sharp decline. Consequently, streamflow electrical conductivity, temperature and δ18O showed a marked tipping point towards higher values. The fast hydrological response of the catchment to snow and meteorological fluctuations, as well as the marked diel fluctuations of streamflow δ18O during the melting period, strongly suggested short meltwater transit times.

(2024) in Hydrological Processes, “Hydrological dynamics of snowmelt induced streamflow in a high mountain catchment of the Pyrenees under contrasting snow accumulation and duration years”

#5 of 2024: Examining the potential and effectiveness of water indices using multispectral sentinel-2 data to detect soil moisture as an indicator of mudflow occurrence in arid regions -- Dear all, I am happy to share our recent work on the applications of remote sensing/GIS for studying the impacts of climate change and natural disasters on vegetation/agriculture in the Middle East. In this article: - We explored the applicability of multispectral Sentinel-2 data for predicting and monitoring soil moisture in inundated areas (in post-cyclone situations) - We demonstrated that spectral water indices can be utilized as soil moisture indicators for predicting high-risk mudflow phenomena in arid regions - We underscored the potential of indirect techniques in validating the performance of spectral indices in inaccessible and large-scale areas -- Article link: https://lnkd.in/d7RgK3Tz -- Hope you enjoy the read and please feel free to reach out to me if you have any questions/comments/collaborative opportunity propositions. We are currently developing projects in the Middle East --- at the intersections of ecosystem restoration, carbon markets, mangroves, remote sensing, biodiversity conservation, disaster management, climate extremities, food security, and ecotourism --- and would love to connect with like-minded researchers and experts. -- Cheers!

And more about groundwater pumping. Are we living in a deflating balloon? What solutions should we consider? Definitely water diffusion over land and gravity whenever possible, but how do we help the Earth to recover from the sinking and tilting?

Water 1. Groundwater: Groundwater is fresh water stored beneath the Earth's surface in underground aquifers. These aquifers can be tapped through wells. Groundwater is a vital source of drinking water for many communities and is also used for agriculture and industrial purposes. 2. Surface Water: Surface water refers to freshwater sources found on the Earth's surface, such as rivers, lakes, reservoirs, and ponds. These sources are replenished by precipitation (rain and snow) and can be readily accessed for various uses, including drinking water, irrigation, industrial processes, and recreation. Where does most of the water on Earth come from? Outer space. Water ice is actually pretty ubiquitous in the universe. The rings of Saturn are mostly water ice. So are comets. In the early history of the solar system, there was a lot more water ice shooting through the solar system. Most of it fell into Jupiter, but what didn’t fell into the rest of the planets. Saturn’s rings are most likely the result of Saturn’s gravity tearing apart an ice comet that came too close. Ice comets fells on Mercury and Venus and immediately evaporated, releasing the water vapour back into space. They fell on Mars too, but most of that water remained ice. Some evaporated, became rain and formed minerals that require liquid water, like gypsum. Here on Earth, it was just warm enough after carbon dioxide levels went up thanks to volcanoes to turn the ice from comets into a liquid, and earth was just big enough and cool enough to prevent all the water from evaporating and escaping back into space. Because, truth be told, there isn’t a lot of water on earth now, and a lot of it is still ice, and another portion is water vapour. But water is still falling to earth, just not very much, and most of it turns to vapour on the way down. Now, no one is quite sure whether the water came in one large event (mega comet striking earth) or lots of smaller ones. In today’s solar system comets have to travel massive distances to get to the planets, and most of them don’t hit a planet. However, some do. Here’s the remnants of Shoemaker-Levy hitting Jupiter But there’s still lots. The Oort Cloud, which is about 1,000 Astronomical Units from the Sun (1 AU = distance from sun to earth, about 93 million miles) is estimated to have a mass of water equal to five times the entire mass of the earth. It’s very thinly spread of course. Two close chunks of ice in the Oort Cloud will be roughly as close together as Earth and Saturn when they’re closest to each other. www.OurWaters.org "From Source to Sea"

【Use of Groundwater, Baseflow and SPEI to Evaluate Water Resources in Michigan, USA】 Full article: https://lnkd.in/gzr_EpwW (Authored by Sawyer Schnettler, et al., from University of Wisconsin at Stevens Point, USA.) Surface and #groundwater respond to both land surface processes, land use, and climatic variables, and should be integrated into water management decisions. This study examines daily discharge data from 46 surface water gauges with high baseflow contributions and groundwater elevation from 28 observation wells in Michigan, and determines baseflow and standardized both annual average #baseflow levels (SDBF) and groundwater levels (SDGW) from 1960 to 2022 by using established hydrograph separation techniques, in order to evaluate water resources in Michigan. #SPEI #Drought
