The movement of particles on the river boundary layer is a complexphenomena which can be never solved by a deterministic approach. Theunsteady non uniform conditions in flow boundary layer show the result ofwater surface and bed stream changing with time and location of particles.To determine the movement of boundary layer particles other new theoriesabout stochastic processes using the theory of probability and statistics inriver alluvial channels will give better results.

Bank full discharge is generally considered to be the dominant steady flow which would generate the same regime channel shape and dimensions as the natural sequences of flows would. This is because investigation on the magnitude and frequency of sediment transport have determined that for stable rivers the flow which in the longer term transports most material has the same frequency of occurrence as bankfull flow. For stable gravel-bed rivers, this is considered to be the 1.5-year flood.

Climate change conditions a wide range of impacts such as the impact on weather, but also on ecosystems and biodiversity, agriculture and forestry, human health, hydrological regime and energy. In addition to global warming, local factors affecting climate change are being considered. Presentation and analysis of the situation was carried out using geoinformation technologies (radar recording, remote detection, digital terrain modeling, cartographic visualization and geostatistics). This paper describes methods and use of statistical indicators such as LST, NDVI and linear correlations from which it can be concluded that accelerated construction and global warming had an impact on climate change in period from 1987 to 2018 in the area of Vojvodina – Republic of Serbia. Also, using the global SRTM DEM, it is shown how the temperature behaves based on altitude change. Conclusions and possible consequences in nature and society were derived.

Waptia-like euarthropods existed for rather a long time in the Early Cambrian of eastern Yunnan; well preserved representatives come mainly from three Burgess Shale-type biotas: Chengjiang, Xiaoshiba and Guanshan. Here, we introduce a newly-discovered bivalved euarthropod from the Guanshan biota, the specific identity of which cannot be confirmed due to the absence of soft parts and poor preservation of the specimen, but its general morphology allows it be attributed to Waptia. Two representatives from the Chengjiang and Xiaoshiba biotas are also reconsidered: the preservation mode and length of specimens of Clypecaris pteroidea are variable; Clypecaris serrate has limbs beneath the carapace, which can number up to at least 4 pairs. The fossil sections bearing Waptia-like euarthropods occur over a wide area around Dianchi Lake.

One of the challenges facing geography educators at higher education institutions in South Africa is to prepare students by providing them with an integrated conceptual and pedagogical toolkit that would adequately equip them to teach a type of geography that is current and relevant to local (but also global) environmental and social phenomena. As an intra-disciplinary science, Geography offers multiple avenues for fostering this type of integration, yet as argued elsewhere, [1] because of a fragmented school Geography curriculum, teacher educators struggle to foster holistic and integrated learning among novice student teachers. In fact, academic geographers most often privilege their own field of specialisation rather than work towards integration [2]. Ultimately, this perpetuates a fragmented teaching practice and conceptual understanding of geographical phenomena. This paper provides a theoretical exploration to demonstrate how Geography Education could retain its holistic nature and advance integration by (re)turning to its own intra-disciplinarity. It was found that the notion of “place” (one of Geography’s big ideas) could serve as a potential point of departure for fostering integrated thinking in the discipline. The argument is made that place-based approaches offer fertile avenues to pursue in Geography Education programmes for equipping student teachers with a holistic conceptual and pedagogical toolkit.

Hydrological information forecasting is the focus of hydrological work, and it has close relationship with social development and people's life. After long-term development. More and more advanced information technology has gradually been applied in hydrological information forecasting, among which GIS has effectively improved the level of hydrological information forecasting.This paper analyzes the application of GIS in hydrological information forecasting to provide an in-depth understanding of this technology.

Urban sprawl is a challenge of the century across the globe; however its greatest impact is felt more in developing countries mainly due to its poor planning and ever increasing population. To ascertain how this affects a notable African city, Abuja, a questionnaire design was employed to elicit resident’s perception on the causes and effects of sprawl in the city. A principal component analysis was performed to simplify the relationship between large bodies of variables involved. This was able to collapse the 14 variables representing the causes of sprawl extracted from the response of the respondents and 9 variables representing the effects of sprawl on the environment and on the residents into significant and orthogonal components that explained the variables in the observed data. Among the nine factors that loaded highly on the components, population was the major factor discovered to be responsible for the sprawl. The analysis further showed the main effects of the sprawl on the city as: loss of biodiversity, high dependency on car, traffic congestion, land degradation, alteration of microclimate, destruction of aesthetics, increasing crime wave, pollution and waste management problems. Adhering to the guidelines on urban development for the city will help the residents not to be prone to the effects of urban sprawl and help to maintain good environmental standards and less spending on maintenance on the part of the government.

The worldmaking possibilities of domestic tourism provide Aboriginal and Torres Strait Islander people in Australia with the potential to take leadership over the challenging interpersonal encounters necessary to the process of reconciliation. This proposition is drawn from a philosophical hermeneutic view of domestic tourism hosts and guests as always already bound by complex histories they cannot change. The paper demonstrates that tourism can enable Aboriginal and Torres Strait Islander people to operate enterprises based on customary cultural law of neutral meeting places attuned to the difficult interpersonal challenges of Reconciliation. Neutral meeting places do not impose reconciliation onto domestic tourists, the intent is to instead exercise everyday humanity and compassion while enabling visitors to fulfil their travel desires. The findings suggest that visitors can become oriented to Aboriginal ways of being and stimulated to learn. As interactions progress, visitors can reach readiness to take up opportunities for genuine dialogue with Aboriginal hosts. Outcomes raised in this paper highlight that tourism can enable Aboriginal and Torres Strait Islanders, as colonised people, to implement their cultural authority to take leadership over perplexing historical legacies woven through the fabric of a Western-dominated society conditioned by colonialism.
