Improving the Resolution of GRACE Data for Spatio-Temporal Groundwater Storage Assessment
GRACE GLDAS terrestrial water storage groundwater storage random forest model downscaling
2023/12/7
Groundwater has a significant contribution to water storage and is considered to be one of the sources for agricultural irrigation; industrial; and domestic water use. The Gravity Recovery and Climate...
Recovering phosphorus from corn ethanol production helps reduce groundwater pollution（图）
Recovering phosphorus ethanol production groundwater pollution
2020/3/13
Dried distiller's grains with solubles, DDGS, are a product of corn ethanol processing that's commonly used as feed for cattle, swine and poultry. However, DDGS contains more phosphorus than the anima...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)
air pollution Black Triangle historical deposition long-term modelling mass balance soil solution soil chemistry
2015/3/13
Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred short...
Environmental impact of landfill on groundwater quality and agricultural soils in Nigeria
chemical land use parameters pollution wastes water
2015/3/5
Physical, chemical and bacteriological analyses were carried out of water samples from three boreholes located near a landfill, and or soil samples at Akure, Nigeria, to ascertain the effect of the du...
Sustainable Use of Groundwater with Underground Dams
groundwater sand storage dam subsurface dam water supply
2011/2/24
A subsurface dam is a facility that stores groundwater in the pores of strata and uses groundwater in a sustainable way. These dams have many merits that surface dams do not, e.g., land is not submerg...
An overview of the effects of forest management on groundwater hydrology

2010/8/31
This paper provides an introduction to the role of groundwater in watersheds, presents an overview of groundwater resources in British Columbia, and reviews the potential effects of forest management ...
Radioactivity Prospecting for Groundwater Development and a New Prospecting Device with a Plastic Scintillator
buried fault zones Compton edge fracture groundwater resources γ-rays
2010/10/25
A large amount of undeveloped groundwater may still be left in fractured rocks of rocky mountainous areas. Points with high potential for groundwater development may be found near fault zones. The ind...
Damage to Pot-cultured Carrot Growth due to a Temporarily Raised Groundwater Level and Flooding Period
excess moisture injury, growth retardation, soil moisture, root, rot
2010/11/24
Temporary rise in groundwater level and flooding period experiments were carried out to examine excess moisture injury in pot-cultured carrot.
Quantitative Analysis of Groundwater Effluent and Reservoir-Water Influent in a Small Pond Using 222Rn- and Water-Balance Equations
stagnant film dispersion
2009/9/10
Percolation of water from a pond may cause a landslide in a hilled rural area. Before measures to prevent such landslides can be planned, it is essential to identify reservoir-water influent from the ...

2009/7/24
Okinoerabu Island is one of the typical agricultural districts in Southwest Islands of Japan. More than three times as much pesticides as the nationwide average are consumed on each unit area of land...
The Effects of High Groundwater Level on the Growth and Yield of Supernodulating Soybean Cultivar "Sakukei 4" with Special Reference to Flowering and Seed-Setting Habit
Flowering and seed-setting habit High groundwater level Number of pod
2009/7/7
Supernodulating soybean cultivar "Sakukei 4" has a high nitrogen fixing activity. The yield of soybean is reduced under high groundwater-level conditions, but the reduction might be mitigated by usin...
Monitoring of inorganic nitrogen in surface and groundwater at the intensive farming villages of the Red River Delta, Viet Nam
Ammonium-N Chemical fertilizer Farming village Nitrate-N
2009/3/12
The quality of surface water (canal and pond water) and groundwater (well water) was monitored with an interval of 6 months from 2002 to 2005 at two farming villages near Ha Noi, Viet Nam. In the vill...
Influence of groundwater depth and available soil water on evapotranspiration and plant growth
actual evapotranspiration plant available soil water dry matter yield cropland grassland coniferous forest
2008/11/24
There is a close relationship between available soil water and water consumption as well as plant growth if we assume adequate soil aeration. Transpiration and plant growth increase with an increasing...
