The river absorption capacity determination as a tool to evaluate state of surface water [PDF]

open access: yesHydrology and Earth System Sciences, 2018
In order to complete a thorough and systematic assessment of water quality, it is useful to measure the absorption capacity of a river. Absorption capacity is understood as a pollution load introduced into river water that will not cause permanent and

Analysis of precipitation variability over Satluj Basin, Himachal Pradesh, India: 1901–2013

open access: yesJournal of Water and Climate Change, 2021
Himachal Pradesh is a mountainous state in the Indian Himalayas, which spreads over an area of 55,000 km2. The state has a unique geography, which influences the climatic variability of the state. In the present study, Satluj Basin has been considered as

Water surface wavelets [PDF]

open access: yesACM Transactions on Graphics, 2018
The current state of the art in real-time two-dimensional water wave simulation requires developers to choose between efficient Fourier-based methods, which lack interactions with moving obstacles, and finite-difference or finite element methods, which handle environmental interactions but are significantly more expensive. This paper attempts to bridge

Effects of Matric Potential Threhold Used for Control of Shallow Drip Irrigaion on Growth and Yield of Alfalfa

open access: yesGuan'gai paishui xuebao, 2023
【Objective】 Matric potential measured at a position below the emitter is often used as a threshold to control drip irrigation. In this paper we investigate the effect of the threshold on growth and yield of alfalfa irrigted by shallow drip irrigation ...

Water on graphene surfaces [PDF]

open access: yesJournal of Physics: Condensed Matter, 2010
In this paper, we summarize the main results obtained in our group about the behavior of water confined inside or close to different graphene surfaces by means of molecular dynamics simulations. These include the inside and outside of carbon nanotubes, and the confinement inside a slit pore or a single graphene sheet.

The Efficacy of Acidified Drip Irrigation for Reducing Soil pH in Remediating Heavy Saline Coastal Soils

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Heavy saline coastal soil is a valuable land resource but its high salt content and sticky texture, along with its high sodium adsorption ratio and shallow groundwater table, makes it difficult to remediate.

Water surface is acidic [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Water autoionization reaction 2H 2 O → H 3 O − + OH − is a textbook process of basic importance, resulting in pH = 7 for pure water. However, pH of pure water surface is shown to be significantly lower, the reduction being caused by proton ...

Spatiotemporal Heterogeneity of Water Conservation Function and Its Driving Factors in the Upper Yangtze River Basin

open access: yesRemote Sensing, 2023
The water conservation function (WCF), as one of the most critical ecosystem services, has an important impact on the ecological sustainability of a region.

Persisting Water Droplets on Water Surfaces [PDF]

open access: yesThe Journal of Physical Chemistry B, 2010
Droplets of various liquids may float on the respective surfaces for extended periods of time prior to coalescence. We explored the features of delayed coalescence in highly purified water. Droplets several millimeters in diameter were released from a nozzle onto a water surface.

Optimal Postprocessing Strategies With LSTM for Global Streamflow Prediction in Ungauged Basins

open access: yesWater Resources Research, 2023
Streamflow prediction in ungauged basins (PUB) is challenging, and Long Short‐Term Memory (LSTM) is widely used to for such predictions, owing to its excellent migration performance.
