Texto completoRivers often present a wavy bed topography due to the presence of bars, corresponding to large sediment deposits alternating with deeper areas (pools). Intense and continual river engineering works altering the river geometry, flow regime and sediment supply can impact bar morphodynamics at the reach scale. A deep knowledge of bar processes is important for river managers, because bars actively control the river bed topography and influence bank erosion, with consequences for navigation, water intakes, infrastructure and the quality of their habitats. Although the origin of bar formation and propagation is well understood, the understanding of bar morphodynamics in rivers remains limited due to the non-linearity of combined natural and anthropogenic effects. Sediment non-uniformity is an inherent characteristic of rivers, but its impact on bar properties, even considering simple configurations, is still unclear. This Ph.D. thesis aims at investigating the impact of sediment size heterogeneity on bars in rivers with non-erodible banks, using a two-dimensional morphodynamic model implemented in the Telemac-Mascaret system. The necessary model developments are brought to comply with the state of the art on the modelling of heterogeneous sediment with bars. Then, the model is used to study bar morphodynamics in a straight channel on the basis of laboratory experiments. Eventually, the analysis is transferred in a 1 km reach of the Loire river characterized by a relatively complex geometry. General outcomes validate the modelling approach and demonstrate the application portability for other study cases, shed more light on the relationship between non-uniform sediment and bars, and can be later used as recommendations for river managers

A disponibilidade de ?gua e a sua devida qualidade configuram como fatores essenciais ao desenvolvimento humano, e, por isso, a avalia??o da qualidade da ?gua representa, dentre outras, uma ferramenta eficiente para a gest?o dos recursos h?dricos. O rio Set?bal ? o ?nico rio perene no munic?pio de Jenipapo de Minas, Minas Gerais, Brasil. A constru??o da barragem de Set?bal no munic?pio foi um empreendimento que visou a garantir a perenidade do rio Set?bal e, consequentemente, promover o desenvolvimento socioecon?mico atrav?s do uso da ?gua para a agricultura irrigada. A quantidade de ?gua por si s? n?o ? suficiente para promover o desenvolvimento, ? preciso, ainda, que a ?gua disponibilizada seja garantida com a devida qualidade. Assim, este trabalho objetivou caracterizar a qualidade da ?gua do rio Set?bal utilizando o ?ndice de Qualidade da ?gua (IQA) e os padr?es estabelecidos na Resolu??o do CONAMA 357/2005, bem como analisar os efeitos socioecon?micos decorrentes da maior disponibilidade de recursos h?dricos a partir da constru??o da barragem de Set?bal, no Munic?pio de Jenipapo de Minas - MG. Os dados que atestam um poss?vel desenvolvimento socioecon?mico no munic?pio foram coletados em ?rg?os p?bicos. Para a caracteriza??o da qualidade da ?gua, seis amostras foram coletadas entre junho de 2015 a junho de 2016, em pontos estrat?gicos, sendo analisados os par?metros: potencial hidrogeni?nico (pH), oxig?nio dissolvido (OD), temperatura, demanda bioqu?mica de oxig?nio (DBO), nitrato (NO3-), f?sforo (PO4-3), cloretos, turbidez, s?lidos totais, ferro total, coliformes totais e Escherichia coli. O IQA foi calculado a partir da metodologia proposta pelo Instituo Mineiro de Gest?o das ?guas IGAM. Dos resultados obtidos, concluiu-se que a maior disponibilidade de recursos h?dricos tem fomentado o desenvolvimento da agricultura irrigada com o aumento do n?mero de projetos de irriga??o e a produtividade agr?cola. A ?gua do rio Set?bal, nos pontos de amostragem, apresentou um IQA predominantemente de n?vel m?dio, por?m com algumas vari?veis em desconformidade com a Resolu??o do CONAMA 357/2005, como elevadas concentra??es de ferro e de turbidez, fazendo com que as duas esta??es amostrais ficassem em desacordo com o enquadramento do rio que ? de Classe 2.

The water availability and its due quality sets essential factor to the human development, and, therefore, the evaluation of the water quality represents, amongst others, a efficient tool to water resources management. Set?bal river is the only perennial river in the Jenipapo de Minas, Minas Gerais, Brazil. The construction of Setubal Dam in the county was an enterprise that aimed to maintain the Setubal River?s perennial, and, consequently promote the socioeconomic development through the usage of the water for irrigated agriculture. The water quantity by its own, it is not enough to promote development, it must, also, the available water be guarantee with a due quality. Thereby, this work had as objective to characterize Set?bal river waters quality, using the Quality Index Water (QIW) and the patterns settled down in the CONAMA?s 351/2005 Resolution, as well, analyze the socioeconomic effects from the increased availability of water sources from the construction of Set?bal Dam, in the Jenipapo de Minas - MG. The data that shows a possible socioeconomic development in the county was collected in public agencies. To characterize water quality, six samples were collected between 2015 June and 2016 June, in strategic spots, with these parameters being analyzed: hydrogen potential (Hp), Dissolved oxygen (DO), temperature, biochemical oxygen demand (BOD), nitrate (NO3-), phosphor (PO4-3), chlorides, turbidity, total solids, total iron, total coliforms and Escherichia coli. The QIW was calculated from the methodology proposed by Instituto Mineiro de Gest?o das ?guas (IGAM). According to the results, it is concluded that the increased availability of water resources has fostered the development of irrigated agriculture with the raise in the numbers of irrigation projects and the agricultural productivity. Set?bal river water, in the sampling points, presented a QIW predominantly middle level, but with some variables in disagreement with the CONAMA?s 351/2005 Resolution, like high iron and turbidity concentrations, what put that two sampling stations in disagreement with the river framework, which is Class 2.

Texto completoMolti modelli sono stati proposti per simulare e comprendere l'evoluzione a lungo termine dei fiumi meandriformi. Ciò nonostante, alcuni problemi di modellazione ancora necessitano di essere risolti, come ad esempio la stabilità delle simulazioni a lungo termine quando sono tenute in considerazione le variazioni di larghezza. Questa tesi propone un approccio fisicamente-statisticamente basato per simulare l'evoluzione dell'argine del fiume, cosicché i processi di erosione e deposizione agiscano indipendentemente, con una soglia di sforzi tangenziali specifica per ciascuno di essi. Inoltre, l'evoluzione della larghezza è connessa con una distribuzione di probabilità specifica per ogni fiume. Le analisi di un campione rappresentativo di configurazioni meandriformi, estratte da immagini Lidar, indicano che la funzione di densità Generalizzata dei Valori Estremi (GEV) descrive in bene la distribuzione delle larghezze lungo la sezione trasversale del canale. Per un dato fiume, i parametri della della distribuzione si mantengono praticamente costanti nel tempo, con variazioni significative osservate solo nel caso in cui eventi di "taglio del meandro" allunghino significativamente la lunghezza del fiume. il vincolo della larghezza del fiume basato sull'assunzione della distribuzione di probabilità GEV assicura la stabilità delle simulazioni a lungo termine, mano a mano che il fiume si sposta attraverso la piana alluvionale adattando la sua larghezza. L'applicazione del modello a un ramo del fiume Ucayali sembra riprodurre in maniera soddisfacente l'evoluzione della pianura del fiume e produce valori realistici delle larghezze della sezione trasversale. Il secondo argomento considerato nella tesi è la formazione di chute cutoff, che producono cambiamenti sostanziali e non locali nella piana del fiume, influenzando in tal modo l'evoluzione morfologica. L'occorrenza di questo tipo di cutoff è uno degli eventi meno prevedibili nell'evoluzione dei fiumi, dal momento che un gran numero di fattori di controllo sono coinvolti nella loro formazione e mantenimento. Negli ultimi anni contributi significativi sono comparsi in letteratura, che chiariscono i complessi meccanismi che dapprima portano all'incisione dei chutes attraverso la piana alluvionale, e che alla fine determina il destino sia della curva tagliata e del nuovo canale. In ogni caso, l'argomento non è ancora risolto, e una struttura sistematica fisicamente basata è ancora mancante. In questa tesi, sono evidenziati due differenti fattori forzanti che portano alla formazione di chute cutoffs, l'inerzia del flusso canalizzato e l'eterogeneità topografica e dei sedimenti della pianura alluvionale. Usando due modelli idrodinamici, vengono studiate le caratteristiche generali dei processi che guidano i chute cutoffs, valutando alcuni casi studio rappresentativi.

Texto completoIn this study, 16 young Swedish adults share their personal stories about their weddings. The stories start with the couples’ decisions to marry and end with the individual experience of the wedding ceremony. Half of those interviewed have a civil ceremony and the rest marry in church. The study’s purpose is to understand the meaning that young adults create in their weddings and in their stories about them. In the analysis I use narrative and reflexive method combined with theories from sociology of religion, cultural sociology, sociology of the family, ritual studies and gender research. The key result achieved by the study is that weddings unify as well as create tensions. On the micro level, between two individuals, the rite is integrating. Interviewees justify their marriage with the argument that it strengthens ties within the family, in which children are a central part. This applies both to an emotional aspect and to a legal and financial aspect. At the same time, the stories contain notions of how the bride and groom should behave and appear in the wedding context, which may lead to conflicts between the man and woman. The bride is understood to be the main character and the man is supposed to play a supporting role. This legitimises a gender-based division of labor. On the meso-level, the wedding is experienced as a unifying force especially in the relationships of church wedding couples to family and friends. Several couples with civil marriages, however, do not want anyone else on their wedding and separates themselves from other people. On the macro-level, in society, unification appears in the interviewees’ experiences of being part of a collective, those who follow the norm for what a "real" family is. A comparison between the two wedding groups (civil and ecclesiastical) shows, however, one further aspect of tension. A distinction appears between human beings resulting in two groups: those who do the “right thing” (have a big church wedding) and those who do not. This leads to intersectional effects, concerning gender and class, on each individual. The integrating and separating effects of weddings are also seen on the meta-level, within academia. On the one hand, various research disciplines can meet in studies of weddings. But in the selection of the types of weddings that are studied, there are often priorities made that result in distinctions being made. Most studies focus on big weddings, and primarily on church weddings while the others are neglected. My dissertation contributes to the visibility of the common, but publicly almost invisible rite; the small civil wedding.

Texto completoThe current research investigates the morphodynamics of gravel alternate bars in an engineeredmountainous river. The experimental site corresponds to an 8 km long reach of the Arc River, in the French Alps. An analysis of historical maps and recent aerial photographs and topographic campaigns shows that the original braided river bed has evolved to a straight bed with alternate bar system constrained within two embankments following two centuries of man-made engineeringprojects. In the mid 1990s the river bed was flattened to fit a trapezoidal cross-sectional design. However, alternate bars re-appeared in less than ten years. An analysis of the controlling factors of bar formation and evolution is provided. Field observation and 1D numerical analysis suggest that the alternate-bar pattern represents a quasi-equilibrium state of the river bed. A singlegravel bar within the reach was monitored 18 times from 2006 to 2012. A methodology of DTM construction based on breaklines is proposed for river beds and an error estimation is presented. DTM differencing technique was used to detect morphologic changes of the gravel bar. Therefore, the gravel bar and main channel dynamics were analyzed relative to main controlling processes suchas extreme hydrologic events, sediment supply, hydrograph shape, bed shear stress distribution andriver energy. Sediment supply and hydrograph shape appeared to be the main factors influencing the study site sediment budget. Moreover, 2D numerical modelling of water flow and sediment transport was performed. Sensitivity analysis was conducted to yield results in agreement with observations. Simulations revealed the relevance of the interaction between fine sediments and gravels on the bar dynamics

Texto completoThe upper Coxim River Basin (UCB) has an area of approximately 1375 km² distributed in the northern portion of Mato Grosso do Sul in São Gabriel do Oeste-MS and Camapuã-MS cities. The Coxim River is inserted in the Paraná River Sedimentary Basin, but it belongs to the Upper Paraguay River Basin. The main goal of this research is to propose a model of physical-territorial management for the UCB through the preparation of an environmental zoning using remote sensing and geoprocessing techniques. The theoretical and methodological basis consisted of environmental integrated analyses starting from the systemic perspective of the concept ecodynamics unities. Spatial data used were arranged in a database implemented in a Geographic Information System (GIS). It consists in topographic maps at 1:100.000 scale, satellite images, Landsat 5 and 7, SRTM interferometric radar image, thematic maps existing and field data. The generation of the of physicalterritorial management model was carried out considering preparation of UCB relief mapping, potential natural erosion, environmental fragility, environmental legislation and evaluation of land-use and land-cover changes during the years 1966, 1986 and 2006. Results indicated a significant relationship between landforms and their uses: mechanized agriculture in the Chapada of the São Gabriel and livestock development on the Plateau Taquari hills. The major areas of environmental degradation were identified in the lower course associated with livestock activity mapped as the highest potential erosion and high fragility area. The mapping of environmental legislation presented strong incompatibility between land use and environmental regulations especially aggravated in the 1980s. We identified four environmental areas: a) Area of Legal Restrictions, b) Productive Rural Area, c) urban area, and d) Zone of incongruities. The guidelines set out by the type of land use proposals were: a) Priority areas for permanent preservation (maintenance of natural vegetation and permanent preservation areas), b) priority area for rehabilitation and preservation (in areas of inconsistencies run the reforestation with native species savanna), c) Areas for sustainable use (allocation of farming, agriculture and agroforestry or forestry).

This research aims to explore cyclists’ recreation motivation, experiences and levels of satisfaction regarding the bike trails of Liyu Lake, Qixintan and Baibao River in Hualien County, and to compare the differences that variables of different background make in cyclists’ recreation motivation, experiences and levels of satisfaction and further analyze their correlation. The research subjects are the cyclists using bike trails of Liyu Lake, Qixintan and Baibao River. The methodology of this study employs questionnaire survey and purposive sampling approach. The designed research tool is the “Scale Questionnaire of Cyclists’ Recreation Motivation, Experiences and Levels of Satisfaction Regarding the Bike Trails of Qixintan, Liyu Lake and Baibao River”. The collected data was arranged and analyzed according to the research purpose by means of statistical methods namely T-test, One-way ANOVA, Scheff’s method, and Pearson product-moment correlation. The results of this study indicate that the main purpose of people’s cycling recreation on the bike trails of Liyu Lake, Qixintan and Baibao River is to join the cycling team and cycle leisurely while races serve as a supplementary purpose. People working in the service industry and aged between 30~39 are the major participants. The variables of cyclists’ different background make partial significant differences in recreation motivation, experiences and levels of satisfaction. Cyclists’ recreation motivation appears to have a significant positive effect on recreation experiences. Cyclists’ recreation experiences appear to have a significant positive effect on levels of recreation satisfaction. However, cyclists’ recreation motivation appears to have a negative effect on levels of recreation satisfaction. The findings of this research suggest that the related government sectors and cycling associations should make good use of the bike trails of Qixintan, Liyu Lake and Baibao River to hold cycling activities and promote them through the mass media in order to increase cyclists’ motivation for experiencing.

The Study of Intervention Strategy for the River Bed Dust Storm in the Mouth of Bai-nan Stream Chou Yuan-Chun Abstract The estuary of Pei-Nan Stream is located in the northeast of Taitung City, facing eastward toward Fu-Kung Village, westward toward downtown Taitung, southward toward the Pacific Ocean, and northward toward the Taitung Coast Mountains. The stream courses through Taiwan Central Mountains in Hai-Duan Town and then runs along the Taitung Coast Mountains all the way to Li-Chi Fault Zone in Pei-Nan Town. Li-Chi Fault Zone, which is composed of soft, easily eroded shales, has suffered a sever degree of soil loss. With its river bed filled with great amount of sand, gravels, and fine dust, the fault zone has become one of the hot spots of dust storms at the estuary of Pei-Nan Stream. Taitung City, the center of the sixteen villages and towns in Taitung County in terms of geography, population, politics, economics, and culture, is situated in the southwest of Pei-Nan Stream, and has been well-known as “The Sand City”. Every year during fall and winter time, or even right before the arrival of a typhoon, strong northeastern monsoon gales will bring about serious dust storms at the estuary of Pei-Nan Stream. With great amount of dust floating and circulating in the air, downtown Taitung is engulfed in thick layers of dust. The low outdoor visibility and inferior air quality are great endangerments to the residents’ traffic safety, living quality and inconvenience when engaging in agricultural, industrial, and business activities. In order to solve dust storm-related problems, authorities concerned have spent considerable government budgets implementing all sorts of mitigation and prevention engineering such as river bed vegetation restoration, watershed restoration, automatic sprinkler systems, biochemical cementation of sandy river bed soils, or installation of straw sand barrier, but of little or no avail. Every year, dust storms arising from the estuary of Pei-Nan Stream remain to torment the residents of Taitung City. In this study, a probe into those approaches seeking to explain the ineffectiveness reveals that lack of dust storm monitoring, lack of study on mechanisms of dust rising, and lack of analysis and assessments on the intervention engineering over the years are held responsible. This study proposes a set of mitigation and intervention strategies by integrating the data gathered and analyzed from (1) temporal and spatial data on climate, hydrology, landscape and sandy river bed soils collected and cross-examined by in-site inspection conducted from the estuary of downstream of Pei-Nan Stream to downtown Taitung , (2) analysis on the dust storm mitigation and intervention strategies conducted in Taiwan and abroad, and (3) effect assessments of the intervention engineering approaches over the years. The results show that the dust storms originating from the estuary of Pei-Nan Stream are categorized as airborne particulate hazards. Proposed intervention strategies seek to directly deal with the very origin of the dust storm to achieve effective dust storm interventions: (1) improving river bed stabilization and vegetation restoration, (2) building a shelterbelt (windbreak zone) more than 70 meters along the banks of the estuary of Pei-Nan Stream by means of urban or non-urban design projects, (3) planting windbreak trees on a massive scale so that wind flows blowing through the estuary of Pei-Nan Stream can be modified and the erosion of the river bed can be reduced, (4) upgrading the automatic sprinkling systems at the mouth of the stream to help keep the river bed stay moist, and finally (5) restoring and maintaining river bed vegetation to resist drought and reduce wind speed and wind erosion.

Taiwan is the island-type terrain, where abundant water source in has streams throughout individually. People often take a variety of recreational activities in sea and rivers. Da Bao Creek is located in Sanxia District, New Taipei City, where is the most popular and famous spot in northen Taiwan. In recent years, through the implementation of government and voluntary groups to prevent drowning. The safety of river gets very significant results. There only one person got drowned in nearly 4 years. It means that the result of preventing drowning is very significantly. The procedure of research paper is throughout real cases of related duties to prevent drowning, discussing policy , legal and other aspects of executes. The research subjects are based on the first line of actual duty person, planning group, people, issuing questionnaires interview. Focus on basic common sense and concept of drowning, education advocacy, resident safety and distribution of responsible duty. To collect all participants in the survey to perform the prevention of drowning and analyze the result. Discovered that the law of river-drowning prevention is incomplete, people’s water-safe concept is inadequate, the number of duty people is less ,needed special units to prevent drowning. Hope the paper could providing improve for implementation of the recommendations may improve matters or to enhance save drowning probability,reduce drowning accidents.

Dian Bao River is one of the major five rivers in the Kaohsiung County, where there was developed metal industry along both banks of the river. However, some unworthy metal mill owners discharged industrial wastes into the river by stealth, resulting in poor water quality, and thus the department of environment protection has focused on renovating this river. This research has planned for 19 sampling points since June, 2006, and used inductively coupled plasma optical emission spectrometer (ICP-OES) to analyze the content of 48 metal elements in the water and sediment, in order to understand the situation of trace element pollution in the Dian Bao River. The research results indicated that most of the water quality analysis items could meet the standards set by law. The average concentration of total Fe (1.4±0.716 mg/L) and total Mn (0.27±0.184 mg/L) were the highest. Wherein, the total B concentration in the 4 observation stations at the Dian Bao Bridge exceeded Effluent Standards. At the observation station near National Kaohsiung First University of Science and Technology, the total concentration of Zn (0.61 mg/L) exceeded Surface Water Classification and Water Quality Standards. It was found in the result of the long-term (68 times through four seasons in a year) fixed sampling, that the pollution concentration of total As, total B, and total Zn from the observation station at the Dian Bao Bridge was obviously higher than that at the Ciao Zih Tou Bridge, which indicated that the pollutant source was at the place between the Dian Bao Bridge’s upper reaches and the Ciao Zih Tou Bridge. The comparison of the concentration of total Cr, total Cu and Ni, total Fe, total Pb, and total Mn indicated that the potential sources came from the upper reaches of Ciao Zih Tou Bridge. The result of correlation statistic analysis indicated: a high-level and notable positive correlation (r>0.69, P<0.01) was evident among (1) the total B, total Cr and total Cu, (2) total Ni and total As, and (3) total Fe and total Zn. The metals with high correlation between each other probably came from the same pollutant source. The significance of metallic pollution in the water could be divided into three clusters according to the result of spatial distribution and cluster analysis, that is, (1) Wu Shan Bridge to Fong Shan Cuo Bridge at the upper reaches; (2) Fu An Bridge, considered as a cluster itself; (3) a cluster consisting of 11 observation stations. The area with the most serious pollution happened at the second cluster, belonging to the tidal reaches at the lower reaches. The highest average concentration of each heavy metal in the sediment was observed at the Fu An Bridge river section; wherein the highest concentration of total Zn at the Fu An Bridge observation station was 1740 mg/kg dry wt, 2.9 times higher than the standard value regulated by the Soil and Groundwater Pollution Remediation Act; in addition, the highest concentration of total Ni, 645 mg/kg dry wt, was tested at the Bao Si South Street observation station at the Fong Shan Cuo branch, which was 3.2 times higher than the standard value regulated by the Soil and Groundwater Pollution Remediation Act. The vertical distribution of total heavy metal concentration in the sediment at the Fu An Bridge reached its maximum value at about the 40 cm depth, and there was an obvious correlation between the concentration and the content of organic matter in the sample. Although the sediment concentration had a positive correlation with the particle diameter, it was not as obvious as that with the content of organic matter, which indicated that the content of organic matter was the main controlling factor of heavy metal accumulation. In addition, the cluster analysis based on metallic concentration could result in three kinds of clusters. The sediment principle component analysis showed that, the component one consisted of Cr, Cu, and Zu, corresponding with the result of correlation analysis; the component two consisted of Ni, and the principle component three consisted of Pb, both of the components could explain 97.36% of the variations. The component one and two were probably related to the different types of metal industry at this drainage basin, whereas no correlation was found between the principle component three and the metal processing industry. The sediment heavy metal enrichment factor analysis at the Dian Bao Stream indicated that it was better to calculate the enrichment factor based on the Dian Bao Stream background concentration than that by the crustal average concentration, in order to better match the actual situation. The enrichment factors of total Cr(0.9~3.5), total Cu(0.7~3.9), total Ni(1.0~22.1), and total Zn(1.5~17.0)all supported that enrichment effect in part of the observation stations within that drainage basin, especially for Zn. By comparing with 12 domestic and foreign rivers, it was found that the heavy metal pollution in domestic rivers was more serious than that in foreign rivers. There was severe pollution by all heavy metals except the total Cu and total Pb, which should draw attention from relevant entities. Compared with domestic and overseas laws in this regard, the total Ni and total Zn at Dian Bao River has exceeded several standards regulated by law, and the total Ni concentration was 5.7 times higher than the value regulated by the US NOAA TEL, and therefore relevant entities shall keep their eyes on and keep monitoring this problem, and try to develop a sound pollution prevention strategy.

The research on the relationship between the security needs of the rock fisher and the protection of the harbor and coast. Rock Fishing is one of the popular marine leisure activities in Taiwan. However, there are also a lot of accidents about rock fishing since the security notion of rock fishers is not enough. Undoubtedly, the designers are professional and dependable in the domestic marine protection. Nevertheless they just design it in an engineering way. They causes there are some distinction between the needs of rock fisher and the design of the protection. Therefore the research focuses on two place of rock fishing in Kaohsiung to provide questionnaires for the fishers, by means of using the statistical software “SPSS” for data analysis. We can analysis the fishers according to the pattern of behavior, the intention of rock fishing and the degree of satisfaction of the environment.Then investigate deeply the security, demand, willingness of usage and the effect of the protection toward different background to the harbor and coast. After all, we make an induction from that analysis and sort out some useful information from the fishers’ point of view. This research achievement can also provide authority of the government a reference when they are revising the relative law of fishing. We also expect the result can brings some messages to the school and they can strengthen the marine leisure safety education to the students. We hope that can attract the experts to research and investigate more in the marine safety which finally brings a promise and contribution to human life on the ocean.

Aeolian dust episodes (ADEs) are emerging disasters occurred from the bare lands of the Kaoping River in southern Taiwan due to typhoons or thermal convections. Four manual sampling sites located along the Kaoping River were conducted to collect PM10 (aerodynamic diameter ≤ 10 μm) with high-volume samplers in an ADE and on regular days in 2012, as well as PM2.5 (aerodynamic diameter ≤ 2.5 μm) and PM2.5–10 (aerodynamic diameter 2.5–10 μm) in six ADEs in 2013. Additionally, soil samples were collected at five potential locations on the surface of bare lands along the Kaoping River Valley. The five soil samples were completely mixed and then sieved with a Tyler 400 mesh (dp < 38 μm) and then resuspended using a dry powder atomizer in a resuspension chamber. Each soil sample could be divided into two independent fractions (i.e., PM2.5 and PM2.5–10). With regard to the ADE and alluvial samples, this study investigated on their chemical contents, including a total of 13 metallic elements, 9 water-soluble ionic species, and 2 carbonaceous species. Hourly averaged PM10 concentrations increased drastically from noon to evening, and maximum PM10 concentration levels were reached within 3–4 hours. Sea-salt particles (SSs) in PM10 accounted for 3.56%-5.17% on regular days and 11.66%-16.47% during the ADE. Cl- deficit percentages during the ADE (6.33%-14.12%) were much lower than those on regular days (29.49%-40.38%), indicating acidic particles mainly produced by chemical reactions of acidic aerosols with aeolian dust and SSs. Even alkaline aeolian dust is the dominant source of PM10 during the ADE; the atmospheric particles are attributable to acidic particles in the air. Furthermore, ADEs were clustered by the prevailing wind direction as southern and northwestern types according to four Taiwan Environmental Protection Administration air quality monitoring stations along the Kaoping River in southern Taiwan in 2013. With metallic element analysis and nonparametric statistical methods of Wilcoxon rank-sum test and Kruskal-Wallis test, this study successfully derived the metallic indicators of ADEs. The mass ratios of crustal elements (Fe, Ca, or Al) to reference element (Cd) obtained during the ADEs were much higher than those obtained after the ADEs. High mass ratios of Fe/Cd, Ca/Cd, and Al/Cd in PM2.5-10 were observed over the influenced areas of ADEs. Among them, (Fe/Cd)2.5-10 was proven as the best indicator which can be applied to effectively validate the existence of ADEs and evaluate their influences on ambient air quality. Moreover, PM2.5 concentrations during the ADEs were 3-3.6 fold higher than those after the ADEs. PM2.5 should be a contributor to AD, even though the mass ratios of PM2.5/PM10 ranged from 0.05 to 0.20 during the ADEs. Our findings provide valuable information regarding the characteristics of the AD during the ADEs in the Kaoping River. The CMB receptor modeling results that aeolian dust and sea-salts in PM10 were major components of atmospheric particles during the cluster ADEs. The contribution of AD emitted from the bare lands to PM10 concentration was in the range of 11.5%-33.1% along the Kaoping River during the ADEs as well as 7.2%-23.0% after the ADEs. A small amount of finer aeolian dust emitted from the bare lands of the riverbed could still be suspended in the ambient air during the ensuing the ADEs. The AD in PM2.5 ranged from 6.2% to 15.7% during the S-type ADEs and ranged from 1.3% to 17.4% during the NW-type ADEs. Both of them were less than that of PM10 during the S- and NW-type ADEs. The AD was mainly enriched in PM2.5-10 rather than PM2.5 since the formation of PM2.5 was directly related to the process that high-temperature vapors and low volatility compound chemical transformed to PM2.5. Additionally, the contribution of biomass burning rose significantly in the range of 7.6% to 13.9% after the S-type ADEs and 5.6% to 13.3% after the NW-type ADEs, suggesting the open burning of agricultural debris is commonly observed along the Kaoping River in summer. Based on the source apportionment of PM10, the wind speed and wind direction were directly relevant to different contributors, so the S- and NW-type ADEs cause the difference of major contributors for different sampling sites.

Texto completoThis study took place in the Groot Marico River catchment situated in the North West Province of South Africa. The catchment holds many rivers and associated tributaries that are home to a variety fish species with some being endemic to the catchment. A small minnow species, the Marico barb Barbus motebensis was chosen as the study species due to it being endemic to the catchment with limited information available on them with regards to their reproductive status in terms of their reproductive timing and number of potential offspring. Two tributaries from the upper Groot Marico River were chosen as sampling sites for the collection of B. motebensis across the four seasons. These two tributaries presented two genetically different populations, which allowed for a comparison of the findings to ascertain whether any differences in reproductive aspects occurred between the two tributary populations during the different seasons. The Marico barb is under threat from predation pressure posed by the largemouth bass Micropterus salmoides introduced into the system. Micropterus salmoides is a known alien invasive fish that eats any animal food item it encounters, especially fish. Due to B. motebensis and M. salmoides sharing the same habitat preferences, B. motebensis stands little chance of survival in the same water inhabited by the predatory M. salmoides. Many studies have shown bass to drive other fish species to the point of extirpation from a system through predation pressure. Currently B. motebensis is classified as vulnerable on the Red List of Threatened Species, although this status may be further compromised with the presence of M. salmoides...
