Published: December 2020

Abstract
The Three-River Headwater Region (TRHR), also known as China “Water Tower”. It is a sensitive region to climate change and plays a critical role in the hydrology circulation and ecological conservation of the Tibet Plateau. Climate change are greatly impacting the climate of this region. However, there exists large biases in the precipitation simulation for this region. In this study, we explored the impact of resolution and physical schemes on precipitation simulation over the TRHR. The results show that a high resolution is necessary for the precipitation modelling over the TRHR with a complex terrain. The precipitation modelling over the TRHR are sensitive to microphysics schemes and cumulus schemes. The microphysics scheme mainly determines the magnitude of simulated precipitation over the TRHR. The cumulus schemes largely influence the spatial distribution of simulated precipitation over the TRHR. Based on the sensitivity tests, we proposed an optimized combination of parameterization schemes that can remarkably improve the accuracy of simulated precipitation over the TRHR. This study is helpful to understand the mechanism of precipitation formation over the TRHR.

Published: December 2020

Abstract
Heterogeneous Fenton oxidation provides an alternative method of degrading ketoprofen from wastewater. The purpose of this study is investigate the degradation of ketoprofen using iron-supported ZSM5 zeolite catalyst. Iron was impregnated into ZSM5 via the impregnation method, with loading variation of 1wt% and 3.5wt% Fe/ZSM5. Characterization of the catalyst was performed using XRD, SEM, ICP-OES, TGA, BET and TPD. Batch degradation reaction were performed with a working volume of 100 mL ketoprofen solution, mechanically stirred at 900 rpm. Amount of H2O2 used was equivalent to 11 times (in excess) the required stoichiometric amount for ketoprofen mineralization. Catalyst loading was varied between 1 g/L and 4 g/L. HPLC was utilized in determining ketoprofen concentration in the solution during the degradation reaction. Ketoprofen degradation of 100% was observed after 20 minutes using catalyst with 3.5% weight at 4 g/L loading. Iron leaching was also measured using ICP-OES to compare the amount of iron leached between heterogeneous and homogenous Fenton reaction. Percentage of iron leached showed 8.93% and 57.09% for heterogeneous and homogenous Fenton reaction, respectively. The study showed promising results in degrading ketoprofen using an iron-supported ZSM5 via the heterogeneous Fenton reaction with lower iron leaching percentage compared to homogenous Fenton reaction.
Technical and economic challenges for Arctic Coastal settlements due to melting of ice and permafrost in the Arctic
Authors: Gudmestad O T 
Published: December 2020

AbstractThe safety of Arctic coastal villages/settlements is of concern due to melting of the ice cover and the permafrost in the Arctic. The immediate concerns for Arctic coastal settlements are due to a number of causes. These causes can be listed as follows: increased distances of open seas during the storm season, larger storm surges due to longer distances of open water without ice cover, larger waves due to longer fetch lengths, increased permafrost melting caused by warmer summer seasons, larger erosion of melted shoreline, increased number of storms causing accumulation of storm erosion effects, large flooding events destroying houses and facilities as well as infrastructure and fresh water reservoirs. There will be possible offshore slides due to melting of offshore permafrost with potential for tsunami generation, and riverbanks will erode due to the melting of permafrost. Slides caused by increased wetness (for example quick clay slides) will occur and housing and water reservoirs will be damaged. Furthermore, the winter seasons are shorter where winter roads can be utilized and the seasons for hunting from the ice cover is shorter. There will be economic losses for the villages/settlements due to changing climate and in the case of needed relocation of the villages, the economic costs are huge. The paper discusses the effects of these concerns and will suggest certain mitigating measures, which only to a limited extent can relieve the situation. The ultimate solution will be relocation of the inhabitants and in some cases the settlement may be relocated to safe location further inland.

Authors: Yao S S , Zhang Z 
Published: December 2020

Abstract
Taking Nanshan LNG project as background, a 2-D numerical model based on the hydrodynamics and advection-diffusion equation is used to simulate the tidal current field and temperature diffusion caused by the cold water discharge, the distribution of temperature diffusion is predicted, the envelope area of the maximum temperature drop and the temperature drop of water intake are counted. Calculating results show that: (1) tidal current shows a typical reciprocating characteristic in the project area, the outlet is located in the shallow reef area south of the breakwater, with the background velocity less than 0.2m/s; (2) the temperature diffusion distance along the north-south direction is longer than that in the east-west direction. The maximum envelope area of temperature drop more than1°C is less than 0.25km2; (3) Cold water discharge has little effect on the inlet, and the maximum temperature drop at the inlet is 0.68°C, so the layout of outlet is reasonable and feasible. The conclusions can provide technical support to the local government for decision-making.

Authors: Chen J , Wu C 
Published: December 2020

Abstract
In order to identity the ecological-sensitive region in Erhai Lake basin and to supply theoretical assistance for related eco-environmental protection planning, the ecological sensitivity in Erhai Lake basin was assessed and analysed based on the Geographic Information System (GIS), Remote Sensing (RS) and comprehensive-factor ecological sensitivity evaluation method. The results showed that the ecological sensitivity had the positive correlation relationship with terrain fluctuation but had the negative correlation relationship with vegetation coverage and the width of the waters buffer zone. The multifactorial comprehensive ecological sensitivity in Erhai Lake basin held the changing trend from the land to waters, which varied from low sensitivity, moderate sensitivity to high sensitivity. On the foundation of the above results, the waters buffer zone within 100 meters should be more paid attention to in the ecological protection planning. If the transition zone between waters and land was protected well, the waters buffer zone within 100 meters could play a great role in the ecological function of purification and remediation, and biodiversity conservation.

Shaping the Cultural Space of a City on the Example of History of the Lock IV Theatre in Bydgoszcz
Authors: Grześkow Iga 
Published: December 2020

Abstract
The search for ways to develop a separate identity of a city has always involved providing a significant character to urban spaces. Nowadays, in the process of accelerated change and excessive growth, cities lose their individual character and become similar to each other. The elements that create an image of a city are public spaces and cultural and natural heritage. The indicated features of spatial forms and the manifestations of life associated with them allow the recognition of the sequence of city areas and identification with specific places. According to Kevin Lynch, elements of urban composition create cultural identity and symbols of collective memory. The aim of the article is to take up current research issues in the field of urban studies, on the example of history and creation of surroundings of the IV Lock Theatre in Bydgoszcz, in the area of the Old Canal. Assuming that this space creates identity of the place, an analysis was made concerning the architectural and compositional connections of public spaces with greenery in the theatre’s surroundings. In the last 200 years, until the outbreak of World War II in Poland, the process of individualizing this area was subject to conscious, comprehensive planning activities, which affected the image of the entire city. In the area surrounding the IV Lock Theater, which is the main object of research studies, numerous entertainment venues were created, including restaurants and garden cafes, playgrounds for children and adults, and sports fields. Process of degradation of this part of quays began after World War II, and its almost complete destruction took place after the decision to backfill a fragment of the Old Canal in the 1970s. Demolitions included historic locks and a stone bridge of Władysław IV, connecting the Trinity street with Grunwaldzka street, and boulevard layout was broken by removing over 100 historic trees. Currently, attempts to restore the significance and importance of this space are closely related to an initiative to reactivate the IV Lock Theatre in Bydgoszcz. Analyzing the architectural and compositional connections of public spaces around the theater in the context of this historical object as well as the revitalized space will show the directions of further shaping the cultural space of this part of Bydgoszcz, which is important for restoring an image of a city by the water.
The Role of Green Public Spaces of the Old Canal in Downtown Bydgoszcz and Its Impact on the City’s Cultural Landscape in 1773 – 1971
Authors: Grześkow Iga 
Published: December 2020

Abstract
One of the important roles of greenery in public spaces of cities is to shape and complement, on a par with architectural objects, the image of the city and building its identity. Identity is the existence of a physical reflection of the nature of history and the traditions of the city and its inhabitants or urban community, distinguishing them from other places and communities. Through conscious, rational and professional activities creating urban tissue, spatial order is achieved, which forms the basis of the identity of cities and determines their quality. Each city, developing its own social and cultural image, resulting from both history and tradition, as well as changes taking place, should cultivate its separate image. The greenery also decides about the identity of the urban space as the aforementioned factors. They are important in individualising and shaping his landscape. Harmoniously composed and decorated green areas also decide about creating the character of the city and urban spaces. Competition for urban areas and for economic spheres of influence, underestimation of the role of spatial planning, marketization of all activities and spatial chaos as a result - these are factors that have pushed into the background the priority of conscious urban landscape shaping, including greenery in the city center of Bydgoszcz. The purpose of this study is to analyze the role of green public spaces with against the background of the history of the creation and significance of the Old Canal along with the regard to the history and significance of the Old Canal along with the process of individualizing the cultural image of Bydgoszcz over the last 200 years. Used in the past, urban composition solutions can be a reference for new studies and planning activities in this area of the city.
