schematic - the average surface hydrologic response to non-atmospheric rivers (AR) (a & b) and AR (c & d) precipitation events with (a & d) and without (b & c) existing snowpack

(a) Spatial distribution of the 6-month standardized precipitation index (SPI) for 1 October 2022 (left) and 1 April 2023 (right), based on the PRISM monthly precipitation model (Daly et al., 1994; Oregon State University, 2023). Gray lines denote study watersheds. (b) Spatial distribution of GNSS-inferred terrestrial water storage (TWS) in October 2022 relative to the average GNSS-inferred TWS for all months of October over the study period (left) and the same for March 2023 relative to all months of March (right) in equivalent water height. Water-storage changes are calculated from all nine inversion products. (c) Spatial distribution of the 1-month standardized storage anomaly (SSA) for 1 October 2022 (left) and 1 April 2023 (right), derived from the monthly deviations from mean TWS shown in panel (b). (d) Time series of 6-month SPI (top), 1-month SSA constrained by detrended GNSS-inferred TWS (middle), and 1-month SSA constrained by GNSS-inferred TWS with a linear trend retained (bottom), spatially integrated across the Sierra Nevada watersheds. Shaded gray bars at the end of each time series highlight the first six months of Water Year 2023, when atmospheric rivers delivered a significant influx of water.

(a) Vertical displacements of Earth's surface (red = uplift, blue = subsidence) estimated from Global Navigation Satellite Systems (GNSS)
(b) terrestrial water storage (TWS) changes inferred from the GNSS-measured displacements
(c) snow water equivalent (SWE)
(d) cumulative precipitation
(e) CW3E-modeled runoff
(f) CW3E-modeled evapotranspiration (ET)
(g) CW3E-modeled TWS changes for the western United States from 1 October 2022–1 April 2023

Artificial glaciers are man-made structures that store water in the form of ice, usually in regions where natural glaciers are scarce or disappearing. They are built by using various techniques, such as freezing water in pipes, spraying water in the air, or stacking ice blocks. Artificial glaciers can help provide water for irrigation, drinking, and hydropower in dry and cold areas.

"...potential strategy to increase #WaterSecurity...

The technology is a combination of #rehabilitation of marginal #soils, #drainage improvement, #WaterStorage, optimal utilization of available radiant energy, and attenuation of the effects of #frost. The main feature of this system is the construction of a network of #embankments and #canals."
