Detectability of variations in continental water storage from satellite observations of the time dependent gravity field
Author(s): Rodell, M.; Famiglietti, J. S | Abstract: Continental water storage is a key variable in the Earth system that has never been adequately monitored globally. Since variations in water storage on land affect the time dependent component of Earth''s gravity field, the NASA Gravity Recovery and Climate Experiment (GRACE) satellite mission, which will
Using Satellite-Based Terrestrial Water Storage Data: A Review
Land water storage plays a key role for the Earth''s climate, natural ecosystems, and human activities. Since the launch of the first Gravity Recovery and Climate Experiment (GRACE) mission in 2002, spaceborne observations of changes in terrestrial water storage (TWS) have provided a unique, global perspective on natural and human-induced changes in
Impacts of artificial dams on terrestrial water storage changes
Theoretical simulation and field observation of water mass loads in MLRs are essential for monitoring the surface dynamic process during water impoundments. In this study, we calculated the gravity changes, crustal deformation, and strain effects in China from 1950 to 2016 based on the location, dam construction time, and water storage
Spatio-temporal dynamics in soil water storage reveals effects of nitrogen inputs on soil water
Spatio-temporal dynamics in the soil water storage of 0–300 cm depth exhibited a downward movement with the crop development progression. The soil water storage in the 200–300 cm soil depth plays an important role, in grain filling and post-anthesis N uptake.

Seepage field prediction of underground water-sealed oil storage
Predictions of the seepage field of underground water-sealed oil storage caverns (UWOCs) are significant for guiding the work of water curtain systems, ensuring the safety of oil storage operations, and reducing the operational cost of oil storage. Based on the field time-series monitoring data of a UWOC project, a long short-term memory
Water Storage
Soil water storage. Water storage in the soil reservoir can be increased by practices that slow down water runoff and increase water infiltration into the soil. This can be achieved through proper hydraulic arrangements and appropriate tillage. Surface tillage, which results in the roughness of the soil, will help retain water and decrease runoff.
Field capacity, a valid upper limit of crop available water?
1. Introduction. "Field capacity" (FC) is an agronomic measure with prime application in irrigation management, allowing the determination of irrigation to be applied without excessive leaching. Applying the classical concept ( Veihmeyer and Hendrickson, 1931 ), FC can be determined by performing or simulating an internal drainage
