Context At present, many cities are facing severe water-resources problems caused by urbanisation. With the development of remote sensing and geostatistics, they have been widely used in urban water-resource monitoring. Aims To review summarise application geostatistics monitoring water resources prospect for their furtherdevelopment. Methods First, bibliometrics was to analyse existing literature this field. We then discuss use improve capacity, focusing on classification technologies equipment applications surface-water groundwater Finally, a look at future research direction is taken. Conclusions In past decade, relevant has shown an upward trend. The can city’s thereby promoting better cities. Implications future, with addition deep learning, remote-sensing geographic-analysis systems be conduct data analysis more accurately, intelligently, quickly, status resources.

Abstract Hydrogeodesy, a relatively new field within the earth sciences, is analysis of distribution and movement terrestrial water at Earth's surface using measurements shape, orientation, gravitational field. In this paper, we review current state hydrogeodesy with specific focus on Global Navigation Satellite System (GNSS)/Global Positioning hydrologic loading. As cycles through hydrosphere, GNSS stations anchored to crust measure associated land under weight changing loads. Recent advances in GNSS‐based have led exciting applications loading subsequent storage (TWS) estimates. We describe how position time series respond climatic drivers, can be used estimate TWS across temporal scales, improve drought characterization. aim facilitate hydrologists' use GNSS‐observed deformation as an emerging tool for investigating quantifying resources, propose methods further strengthen collaborative research exchange between geodesists hydrologists, offer ideas about pressing questions hydrology that may help answer.

In early 2023, a series of intense atmospheric-river storms eased California’s historic drought, yet the spatiotemporal extent groundwater recovery remains poorly understood. We tracked two-decadal changes in Greater Los Angeles using seismic ambient-field interferometry. The derived hydrographs reveal distinct expressions and surficial water droughts: Whereas surface near-surface storage nearly fully recovered epic wet season only about 25% lost since 2006 was restored. On decadal scale, we find substantial depletion aquifers below 50-meter depth, with limited storm-related recovery. Our analysis underscores need to monitor deep for more complete assessment total deficits, high-resolution tools such as sensing.

Abstract Analyzing the spatiotemporal characteristics and evolution of meteorological hydrological droughts can reproduce process drought propagation, which helps reduce impact improve water resources management. While emerging studies have attempted to build severity index based on cutting‐edge space geodetic observations, few focused propagation using data. In this paper, global navigation satellite systems (GNSS) observations together with precipitation data, we systematically investigated in Yunnan province, Southwest China. We first identified seven from January 2011 May 2021, was mainly concentrated northern lasting for 1–11 months. By contrast, were more severe larger than droughts, 2–16 The time 2–7 months, short southwest but long northeast. Water vapor, precipitation, storage demonstrated a pattern uneven distribution, red river fault (RRF) as boundary, their phase difference also presented notable regional differences, indicating that RRF not only influences spatial variation affects propagation.

Abstract Globally, groundwater represents a critical natural resource that is affected by changes in supply and renewal, as well increasing human demand consumption. However, despite its role, difficult to accurately quantify it beneath the Earth surface. Here, we review several state‐of‐the‐art remote sensing techniques useful for local‐ global‐scale monitoring assessment, including proxies extraction. These include inferring subsurface water from mass using gravitational measurements, analyzing surface height Interferometric Synthetic Aperture Radar, Light Detection Ranging, Airborne Electromagnetic Systems, satellite altimetry. Remote information often used tandem with ground‐based observations such hydraulic head wells, Global Navigational Satellite System monitoring, numerical modeling complement space‐based approaches. In future, fusing different capable of operating various environments will yield additional insight on state rate use across globe.

Abstract The surface displacements measured by the Global Navigation Satellite System (GNSS) provide a unique insight for studying terrestrial water storage (TWS) changes. In this study, we recovered TWS changes from GNSS vertical in Southwest China (SWC) using Slepian basis function (SBF) January 2011 to December 2020. performance of estimated SBF was validated against Gravity Recovery and Climate Experiment (GRACE)/GRACE Follow‐On (GFO) GNSS‐inverted Green's method. results showed that spatial patterns, seasonal, linear trends derived agreed with GRACE/GFO estimates. However, there are still evident differences local scope, GNSS‐derived presented stronger amplitudes more details spatio‐temporal domains than estimates SWC. unconstrained inversion also signal those function, were reliable method regions sparsely distributed stations Additionally, average distance between can be considered as reasonable filtering radius SBF, SBF‐estimated different Gaussian radii had comparable patterns GRACE/GFO.

Abstract Geodetic methods can monitor changes in terrestrial water storage (TWS) across large regions near real‐time. Here, we investigate the effect of assumed Earth structure on TWS estimates derived from Global Navigation Satellite System (GNSS) displacement time series. Through a series synthetic tests, systematically explore how spatial wavelength load affects error estimates. Large loads (e.g., >1,000 km) are well recovered regardless model. For small <10 km), however, errors exceed 75% when an incorrect model for is chosen. As case study, consider sensitivity seasonal within mountainous watersheds western U.S., finding that differ by over 13% collection common global and regional structural models. Errors generally scale with total weight load; thus, long‐term produce significant uplift (subsidence), enhancing errors. We demonstrate experiencing systematic large‐scale variations storage, such as Greenland ice sheet, exhibit differences predicted (over 20 mm) depending choice Since discrepancies GNSS observational precision, appropriate must be adopted inverting observations mass these regions. Furthermore, quantified using independent data altimetry, gravity) present opportunities to use geodetic refine properties seismologically models Earth's interior structure.
