A flash flood is the most common natural hazard that endangers people’s lives, economy, and infrastructure. Watershed management planning are essential for reducing damages, particularly in residential areas, mapping flood-sensitive zones. Flash flooding an interface dynamic between geoterrain system factors such as geology, geomorphology, soil, drainage density, slope, flood, rather than only water movement from higher to lower elevation. Consequently, vulnerability floods necessitates awareness of topographical features. vulnerable zones (FFVZ) map thorough risk assessment minimize its detrimental effects, especially cities like Fujairah with seven wadis flowing into city even though it has two main dams fifteen breaker dams. So, this work, eight satellite image-derived parameters rainfall, elevation, land use/land cover (LULC), soil were combined predict flood-vulnerable using a weighted overlay technique based on geographic information systems (GIS). Each element thematic maps ranked according how study area, 55 km2 being classified very highly 78 high-risk 9.3 moderate 70 low 257 area. In addition, places high level include Airport, Port, some neighborhoods city’s center, oil storage hospitals, universities. Additionally, 1990 present, Landsat Sentinel 2 data showed consistent changes vegetation built-up areas. Therefore, addition helping policy decision-makers make best choices about efficacy area’s protective structures against future, results can also be valuable source information.

Superhydrophobic Bulgy Windmill for Synchronous Efficient Fog Collection and Power Generation

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(12), С. 15496 - 15504

Опубликована: Март 13, 2024

The shortage of freshwater resources is a serious problem faced by mankind in the 21st century. To maximize acquisition resources, numerous fog collectors have been constructed. In process collection accompanied movement wind, mechanical energy brought about wind often ignored. Based on this, inspired beetles and origami art, we designed windmill installation with bump edge. Droplets nucleate at bulge accelerate transport under action centrifugal force. This leads to quick reduces secondary evaporation rate resources. efficiency can reach 2.8 times that original sample. Moreover, convert into electricity while collecting fog, operating voltage single 0.85 V. After array, amount collected power generation be increased multiple times, which realizes efficient use provides new idea for design an collector future.

Nonlinear impact of unconventional water use on water resource sustainability in China: A perspective on water poverty

Ecological Indicators, Год журнала: 2024, Номер 162, С. 112065 - 112065

Опубликована: Апрель 23, 2024

Unconventional water serves as a bridge to sustainability. However, many developing nations still have long way go in terms of unconventional utilization. Different regional characteristics lead different consumption capacities for water. Consequently, more use (UWU) may not necessarily be positive alleviating poverty. there is significant research gap this field. This paper aims answer three key questions: "Whether UWU consistently alleviates poverty?" "Is effect spatially heterogeneous?" and "What role do economic factors play addressing For that, focused on 30 provinces China, with the sample period spanning from 2006 2021. To identify mechanisms through which poverty, employed panel fixed-effects model using Water Poverty Index (WPI) dependent variable square amount an independent variable. The results indicate non-linear impact WPI, significance influenced by GDP per capita (PGDP). Furthermore, threshold regressions were conducted PGDP revealed double-threshold displaying "U" or inverted shape develops: When less than equal RMB 13,574, demonstrates negative WPI; when ranges 13,574 53,653, turns positive; however, exceeds back negative. findings confirm that always better. Sustainable utilization plans resources must tailored local conditions, especially considering unique economy.

A Sustainable Water Resources Management Assessment Framework (SWRM-AF) for Arid and Semi-Arid Regions—Part 1: Developing the Conceptual Framework

Sustainability, Год журнала: 2024, Номер 16(7), С. 2634 - 2634

Опубликована: Март 22, 2024

The evaluation of water resources management practices is essential for usage decisions in regions with limited resources. literature provides numerous assessment frameworks, but many ignore the unique characteristics and conditions some special arid semi-arid regions, such as Gulf Cooperation Council (GCC) countries, which lack any permanent rivers or lakes. Thus, this study, first a two-part series, seeks to develop conceptual Sustainable Water Resources Management Assessment Framework (SWRM-AF). General particular criteria explain how components indicators were identified. SWRM-AF provided here has four (environment, economy, society, infrastructure) 24 indicators. Almost every indicator been selected from briefly explained justified. This research presents, possibly time, clear straightforward directions evaluating each colour-coded tables. To create more holistic framework social like “intervention acceptability” environmental assessing impacts desalination treatment plants have added form applicable regions. Therefore, could work collectively aid process decision-making. next phase validating using participatory approach.

A system dynamics approach to management of water resources in Qatar

Sustainable Production and Consumption, Год журнала: 2024, Номер 46, С. 733 - 753

Опубликована: Март 25, 2024

Rapid global population growth and extensive urbanization threaten water sustainability, hindering sustainable development. This issue is particularly acute in arid regions such as the Gulf Cooperation Council (GCC), where scarce natural resources are overexploited. Effective resource management (WRM) pivotal overcoming this challenge. holistic study presents an innovative approach to address sustainability at a national scale by developing WRM decision support system (DSS) leveraging dynamics modeling (SDM). Employing unique scenario design framework developed study, DSS simulates Qatar's behavior for 2021 2070 according nine clustered policy scenarios presenting different degrees of designed accounting changes physical, environmental, socioeconomic patterns. Our results reveal that "business-as-usual" (BAU) can balance supply demand only 32 years. According best scenario, could be ensured up 50 years increasing 10 % reducing consumption %. Additionally, aid policymakers fostering groundwater conservation strategies proposed using limiting yield safe abstraction level emphasizing significance preserving non-renewable "backstop" country. While marking first research Qatar utilizing SDM tackle national-scale challenges, established model equally applicable other GCC countries similar regions.

Context As a result of the combined impacts global climate change and intensive human activities, water-resources supply–demand imbalance has become prominent, particularly in Yellow River Basin. Aims This study aims to accurately assess changes resilience water-resource supply demand over past few decades. Methods examines resources, economy, society, ecology both aspects assessing water demand. The composite evaluation model based on integrated optimisation weighting an improved grey-target was constructed. Key results Using Basin as example, from 2011 2020, index system (RIWRSS) increased significantly by 69.4%. Among 12 indicators Basin, contribution proportion inhibiting factors decreased 3.7%, whereas driving 70.9%. Conclusions present provided insights into evaluating RIWRSS highlighted disparities between sides Implications expects provide evidence for improvement water-supply conditions resources
