Executive Summary

A major week for global-scale hydrologic modeling saw the release of World-Wide HYPE (WWH), the first application of catchment-modeling techniques evaluated against river flow at the global scale, alongside the UK Earth System Models for CMIP6 and an updated JULES-GL7 land surface configuration. A multi-model permafrost hydrology intercomparison revealed that most land models project surface soil drying despite increased precipitation, highlighting critical uncertainties in high-latitude water cycle projections. Meanwhile, machine learning approaches advanced with deep fusion methods for satellite–gauge precipitation merging and LSTM-based streamflow forecasting, while a global assessment of dam-induced habitat fragmentation for ~10,000 fish species quantified the profound connectivity impacts of current and planned hydropower infrastructure.

Global Hydrologic and Earth System Modeling

This week delivered a remarkable cluster of papers advancing global-scale modeling capabilities. The UK Earth System Models—HadGEM3-GC3.1 and UKESM1—were formally documented for CMIP6, while the JULES-GL7 land surface configuration underpinning these models was also released. A groundbreaking permafrost region model intercomparison revealed that despite projected increases in precipitation, most land models predict long-term surface soil drying, with substantial disagreement among models on runoff and evapotranspiration partitioning. The World-Wide HYPE (WWH) model demonstrated that global catchment modeling using open data and stepwise parameter estimation is now feasible, while separate studies examined the effective resolution of high-resolution atmospheric models and how terrestrial biosphere models simulate rainfall manipulation experiments. The ORCHIDEE land surface model received an improved irrigation scheme, and a novel dynamic model data averaging approach was proposed for combining global hydrological models with GRACE observations.

Climate Change Impacts on Water Resources

Climate change impacts on water resources emerged as a dominant theme, with studies spanning North Africa, South America, and the Asia-Pacific. A comprehensive vulnerability assessment of five North African countries linked physical climate exposure to water resource impacts and social implications, while northern Patagonia faced critical decreases in water resources. The Mann-Kendall test—the workhorse of hydrometeorological trend detection—received a rigorous re-evaluation of its statistical power, and a novel dynamical systems framework shed light on compound wet-and-windy extremes in Europe and Eastern North America. Tropical cyclone intensification under future warming was projected to amplify storm surges in the Pearl River Delta.

Floods, Droughts, and Extreme Events

This week produced important insights into the interconnections between droughts, floods, and human vulnerability. A key study quantified the positive feedback between drought and deforestation in the Amazon, where reduced rainfall facilitates deforestation that further reduces moisture recycling. The interplay between structural flood protection and population density along the Jamuna River in Bangladesh revealed the “levee effect”—where flood protection paradoxically increases mortality risk by attracting settlement to floodplains. A novel “remarkability” framework used social media to define locally meaningful coastal flooding thresholds, while ensemble strategies for flash-flood forecasting were evaluated in the Pyrenees.

Catchment Hydrology, Water Management, and Land Use Change

Catchment-scale hydrology and water management studies were wide-ranging this week. A global assessment of ~40,000 existing large dams found that they fragment the habitats of ~10,000 freshwater fish species, with planned future dams threatening to worsen connectivity losses. At regional scales, the Loess Plateau’s “Grain for Green” revegetation program was shown to significantly alter the regional water balance, while land use and climate change impacts on ecologically relevant flows were modeled in the southeastern United States. Studies of the Changjiang (Yangtze) River quantified Three Gorges Dam impacts on streamflow characteristics, the Yellow River Delta’s hydrological connectivity was linked to plant community structure, and the Buzi sub-catchment in Zimbabwe revealed the water balance consequences of land cover change. Advances in modeling tools included evaluations of the DSSAT-MODFLOW framework for groundwater–irrigation interactions, SWAT sensitivity to rainfall station networks, and performance comparisons of 2D overland flow models.

This study presents DSSAT-MODFLOW, a new modeling framework coupling the crop model DSSAT with the groundwater model MODFLOW for exploring groundwater conservation strategies in irrigated areas.

Dynamic within-season irrigation scheduling for maize production in Northwest China

Authors: Shang Chen, Tengcong Jiang, Haijiao Ma, Chuan He, Fang Xu, Robert W. Malone et al.

Journal: Agricultural and Forest Meteorology · DOI: 10.1016/j.agrformet.2020.107928 · Citations: 53

Matched topics: water management, irrigation

This study develops a dynamic within-season irrigation scheduling method for maize production in Northwest China based on weather data fusion and yield prediction by DSSAT.

Assessing the impacts of different land uses and soil and water conservation interventions on runoff and sediment yield at different scales in the central highlands of Ethiopia

Authors: Tesfaye Yaekob, Lulseged Tamene, Solomon Gebreyohannis Gebrehiwot, Solomon S. Demissie, Zenebe Adimassu, Kifle Woldearegay et al.

Journal: Renewable Agriculture and Food Systems · DOI: 10.1017/s1742170520000010 · Citations: 51

Matched topics: hydrology, runoff, hydropower

To tackle soil erosion and moisture stress, the government of Ethiopia introduced mass campaigns for soil and water conservation. This study quantifies the impacts of various interventions at different scales, finding that while interventions are believed to have reduced erosion and enhanced water resources, quantitative impact assessments at multiple scales remain scarce.

Hydrological connectivity: One of the driving factors of plant communities in the Yellow River Delta

Authors: Jiakai Liu, Bernard A. Engel, Guifang Zhang, Yu Wang, Yanan Wu, Mingxiang Zhang et al.

Journal: Ecological Indicators · DOI: 10.1016/j.ecolind.2020.106150 · Citations: 51

Matched topics: hydrology, river

The current study uses an improved-comprehensive hydrological connectivity structure index based on both soil water conditions and topography to highlight the coupling mechanism among hydrology, edaphic factors, and vegetation in the Yellow River Delta coastal wetlands.

Characteristics of streamflow in the main stream of Changjiang River and the impact of the Three Gorges Dam

Authors: Hong Wang, Fubao Sun, Wenbin Liu

Journal: CATENA · DOI: 10.1016/j.catena.2020.104498 · Citations: 46

Matched topics: river, runoff, streamflow

This study characterizes streamflow in the main stream of the Changjiang (Yangtze) River and quantifies the impact of the Three Gorges Dam on flow regimes.

Hydrological signatures describing the translation of climate seasonality into streamflow seasonality

Authors: Sebastian Gnann, Nicholas Howden, Ross Woods

Journal: Hydrology and Earth System Sciences · DOI: 10.5194/hess-24-561-2020 · Citations: 40

Matched topics: hydrologic model, streamflow, seasonal, hydropower

Seasonality is ubiquitous in nature and closely linked to water quality, ecology, hydrological extremes, and water resources management. This study develops hydrological signatures that capture how climate seasonality translates into streamflow seasonality, providing a new tool for analyzing catchment behavior across different hydroclimatic settings.
