Water, Journal Year: 2024, Volume and Issue: 16(19), P. 2870 - 2870

Published: Oct. 9, 2024

Climate change affects the water cycle, resource management, and sustainable socio-economic development. In order to accurately predict climate in Weifang City, China, this study utilizes multiple data-driven deep learning models. The data for 73 years include monthly average air temperature (MAAT), minimum (MAMINAT), maximum (MAMAXAT), total precipitation (MP). different models artificial neural network (ANN), recurrent NN (RNN), gate unit (GRU), long short-term memory (LSTM), convolutional (CNN), hybrid CNN-GRU, CNN-LSTM, CNN-LSTM-GRU. CNN-LSTM-GRU MAAT prediction is best-performing model compared other with highest correlation coefficient (R = 0.9879) lowest root mean square error (RMSE 1.5347) absolute (MAE 1.1830). These results indicate that method a suitable model. This can also be used surface modeling. will help flood control management.

ABSTRACT Shallow groundwater in many cities around the world is subject to elevated temperatures that pose a risk quality and ecosystems. The objective of this study assess suitability different trend estimation methods for temperature specifically investigate spatio‐temporal long‐term changes water urban Vienna. Twenty‐year data records (2001–2020) from sources were used air, soil, river regarding their annual mean extreme percentile values. effects quality, methods, various time periods analysis investigated. Block bootstrapping combination with Mann–Kendall test was found be suitable method determining significance trends if time‐series are short (10 years), as underlying assumptions lowest among all approaches. Between 2001 2020, average Vienna increased by 0.9 K/decade shallow 0.8 air. However, increase not linear has intensified later decade an 1.4 K/decade. temperatures, represented lower (cold) / upper (warm) 10th soil quantile regression, show strongest air temperatures. For groundwater, these value site‐specific influenced infrastructure interaction water. These results underline importance spatially temporally high‐resolution highlight need aquifer characterisation sustainable use geothermal energy heating cooling.

James Buttle Review: The Characteristics of Baseflow Resilience Across Diverse Ecohydrological Terrains

ABSTRACT The dynamic storage of aquifers is the portion groundwater that can potentially drain to any given point along a stream create baseflow. Baseflow typically occurs year‐round in perennial streams, though characteristics and stability are often most important instream processes during extended dry periods (without precipitation snowmelt) when runoff quickflows minimised. term ‘baseflow resilience’ defined for this review as tendency baseflow streams maintain consistent volume water quality year while under stress from climate variability extremes, with anthropogenic stressors such withdrawals, land use change, degradation. ‘Baseflow has, part, user‐defined meaning spanning supply variables primary interest. Watershed directly impact resilience produce non‐intuitive feedbacks enhance some attributes simultaneously impairing others. For example, permeable corridor geology creates strong stream‐groundwater hydrologic connectivity, yet fast drainage via preferential high‐permeability flowpaths lead streamflow not being sustained periods. Also, shallow sources generally more immediately vulnerable extreme events, warming, salinization, transpiration, drought, compared deeper groundwater. Yet drought influenced by lag years, contaminant legacies may propagate through deep receiving waters decades centuries.

Reconstruction of the Temperature Conditions of Burial-Related Pressure Solution by Clumped Isotopes Validates the Analysis of Sedimentary Stylolites Roughness as a Reliable Depth Gauge

Published: Jan. 14, 2025

Rough surfaces known as stylolites are common geological features that developed by pressure solution, especially in carbonate rocks, where they used strain markers and stress gauges. As applications developing various settings, questions arise regarding the uncertainties associated with quantitative estimates of paleostress using stylolite roughness.
