Abstract This study focuses on the environmental conditions of the Mahanadi Estuary near Paradeep Harbor and the adjacent sea. Data collected from May 2013 to April 2020 from 32 GPS fixed stations was analyzed to assess the water quality in different zones (estuarine, mixed zone, mixed zone south, and mixed zone north) of study area. Parameters such as pH, SST, TSS, nitrite, phosphate, silicate, TOC, chlorophyll, fecal coliform, and heavy metals were used to estimate the Water Quality Index (WQI) for each zone. The study found a deterioration (> 30%) in the overall water quality of the Mahanadi Estuary from 2013 to 2020, potentially attributed to river inflows, port activities, and industrial outflows in to the coastal ecosystem. Seasonal variations in temperature, salinity, turbidity, nitrite, nitrate, and ammonia were observed. The water quality showed a deteriorating trend in estuarine, mixed zone, mixed zone south, and mixed zone north. Based on the water quality indices, the ecosystem shows moderate levels of stress. The degraded water quality highlights the need for a targeted mitigation plan to reduce external pressures and enhance the overall ecosystem quality. Graphical Abstract

Abstract In rural Ivorian communities, women are considered as the guardians of water, undertaking an essential role deeply rooted in local cultural values, ensuring the preservation and management of this vital resource. However, the scarcity of potable water places them under significant pressure, exposing them to heightened risks. Within this context, this study conducted in the Sub-Prefecture of Gboguhé explores the critical link between the cultural values of Bete women and the issue of access to potable water in the region, with a specific focus on the impacts they experience. To achieve this, the study adopts a primarily qualitative approach based on documentary research, direct observations, in-depth semi-structured interviews, and focus groups. The findings reveal that the scarcity of potable water disproportionately affects women in these communities, leading to significant socio-economic consequences. Water points often become scenes of verbal and physical aggression among women, given the difficulties in accessing water in the area, thereby limiting their daily activities and economic participation. Furthermore, they face heightened health risks due to water supply hardships and the consumption of non-potable water from unimproved sources. Additionally, this study offers novel perspectives for transformative actions aimed at addressing the scarcity of potable water, promoting women's social and cultural values, and preserving the essential cultural ties within the Bete communities of Gboguhé and beyond.

Abstract Climate change and irresponsible urbanization practices are anticipated to further exacerbate flood risk. The different soil types’ physical, chemical, and biological characteristics significantly impact surface water movement, porosity, permeability, and infiltration potential. Therefore, soil infiltration is perhaps the most challenging and crucial process to characterize on a field scale. Various methods have been developed to measure the infiltration rate empirically and theoretically. However, the relationship between different soil types and infiltration rates in Sarawak remains unknown as no previous study has been conducted. This study uses the Storm Water Management Model (SWMM) to evaluate the infiltration rates for five different soil types: clay, clay loam, loam, sandy loam, and sand. 30 samples of various types and soil depths were examined at intervals of 0.5 m, 1.0 m, 1.5 m, 2.0 m, 2.5 m, and 3 m. The study was carried out using a standardized slope of 0.7% and an impervious land of 25% with a catchment size of 2 acres. Extreme rainfall data on the 5th and 6th of December 2021 was input into the infiltration model. Results showed that the difference between initial and final water storage of all the investigated soil depths for clay, clay loam, loam, sandy loam, and sand was found to be 48.42 mm, 51.20 mm, 58.01 mm, 66.96 mm, and 115.54 mm, respectively. The findings demonstrated that clay has the lowest water storage capability, followed by clay loam, loam, and sandy loam. Sand could store a comparatively large amount of rainwater. In contrast, sand has the highest infiltration rate with 2.541 mm/h, followed by sandy loam with 1.835 mm/h, loam with 1.432 mm/h, clay loam with 1.039 mm/h. Clay has the lowest infiltration rate, with 0.852 mm/h. This research concluded that sandy soil could significantly reduce surface runoff and help reduce flood risk in urban regions.
气候变化和不负责任的城市化实践预计将进一步加剧洪水风险。不同土壤类型的物理、化学和生物特性显著影响地表水的运动、孔隙度、渗透率和入渗势。因此，土壤入渗可能是最具挑战性和最关键的过程，在田间尺度上进行表征。各种测量入渗速率的方法已经发展到经验和理论。然而，沙捞越不同土壤类型与入渗率之间的关系仍然未知，因为之前没有进行过研究。本研究使用雨水管理模型(SWMM)来评估五种不同土壤类型的入渗速率:粘土、粘壤土、壤土、砂壤土和沙土。在0.5 m, 1.0 m, 1.5 m, 2.0 m, 2.5 m和3 m的间隔内检查了30个不同类型和土壤深度的样品。该研究采用0.7%的标准坡度和25%的不透水土地，集水区面积为2英亩。入渗模型输入2021年12月5日和6日的极端降水数据。结果表明:粘土、粘壤土、壤土、砂壤土和砂土的初始和最终储水量差异分别为48.42 mm、51.20 mm、58.01 mm、66.96 mm和115.54 mm;结果表明，粘土的储水能力最低，其次是粘土壤土、壤土和砂壤土。沙子可以储存相对大量的雨水。砂土入渗速率最高，为2.541 mm/h，其次是砂质壤土(1.835 mm/h)、壤土(1.432 mm/h)和粘土壤土(1.039 mm/h)。粘土的入渗速率最低，为0.852 mm/h。研究表明，沙质土壤可以显著减少地表径流，有助于降低城市地区的洪水风险。

Abstract This bibliographic article on Drought and Water Level examined the relationship between organizations, nations, institutions, authors, references, and publishers. It examined 742 papers from Web of Science at the Nanjing University of Information Science and Technology’s. The total annual publication volume of articles was increased steadily from 2012 to 2021, with China and the United States ranking first and second in terms of publication volume and citations but in quality Switzerland and England were top-level. Institutional-partnership analyses indicated disparities in network density and connections, with the Chinese Academy of Sciences (2012) receiving the highest citations and degrees. The document co-citation analysis (DCA) network was created to improve understanding of the frequency and amplitude of bursts of various publications in separate clusters. The most cited work was J Hydrol (2012), with 302 citations. The analytical tool from CiteSpace collected high-frequency keywords and performed co-occurrence, grouping, and emerging word recognition. Gorges Dam is the most crowded cluster, followed by drought stress. The greatest burst duration and most significant phrase is reservoir (2019), followed by “water quality,” which has a 5 year burst period. Estuaries perform important functions such as water purification and coastal. “Reservoir, water quality, restoration, phytoplankton, temperature, wetland, time series, diversity and carbon dioxide” are the most important terms, while “climate change, drought, water level, impact, growth, variability, response, dynamics, management and model” are the most frequently used keywords. In terms of citations, references, and academic influence, Zhang Q. (2012), the R Core team (2014), and Jappen E. (2015) were the top three contributors. Cook, ER (2013), and Allen, R.G. (2019) ranked first and second in terms of frequency, respectively. In this review work, significant information gaps were discovered in the areas of microbiological dynamics, environmental variables, fen peat incubation, lake water, drought risk reduction, biological ecology, lake acidification, salinity variations, and attribution. Future researchers should focus on these and similar topics, while Chinese and USA authors should concentrate on article quality rather than publishing numbers.
