Several cities in developing countries are challenging the permanent process of urbanization. This generates a great disturbance on the hydrological response of the urbanized area during rainfall events, which can cause floods. Among the disturbances that urbanized basins may suffer, it is found that variations in rain losses (hydrological abstractions) can be estimated by the named volumetric runoff coefficient (CVOL) methodology. In the present study, this methodology is used in an attempt to estimate the hydrological abstraction of two nearby urbanized basins, with different degrees of impermeability, located in the city of Cuenca in Ecuador. The data for that analysis were collected between April and May of 2017. The results obtained indicate that the micro-basin with the largest impervious area presents the higher initial hydrological losses, the higher rate of decrease in abstractions, and the higher stormwater runoff flows per unit area. In addition, the abstractions found in the two urban micro-basins show great sensitivity to the maximum rainfall intensity and do not relate to the antecedent soil moisture. These results demonstrate the importance of having higher pervious surfaces in urbanized areas because they lead to reduce negative impacts associated with increased stormwater runoff on impervious surfaces.

ABSTRACT Although several studies have evaluated the intensity-duration-frequency relationships of extreme rainfall events, these relationships under different seasonal conditions remain relatively unknown. Thus, this study aimed to determine whether the intensity-duration-frequency relationships obtained seasonally from the rainfall records in the winter and summer represent the maximum rainfall events for the city of Pelotas, Rio Grande do Sul state, Brazil. Pluviographic data from 1982 to 2015 were used to create two seasonal series: one for the summer from December 21 to March 20 and the other for the winter from June 21 to September 22. These seasonal relationships were compared with the annual pluviographic data. The intensity, duration, and frequency relationships obtained from the summer rain data adequately represented the maximum rainfall in Pelotas, Rio Grande do Sul state, Brazil. The maximum intensity values of rainfall obtained from the relationship of intensity, duration, and frequency for the winter did not adequately encapsulate the occurrence of rain with greater intensities.

In this study, the time–area curve of an ellipse is analytically derived by considering flow velocities within both channel and hillslope. The Clark IUH is also derived analytically by solving the continuity equation with the input of the derived time–area curve to the linear reservoir. The derived Clark IUH is then evaluated by application to the Seolmacheon basin, a small mountainous basin in Korea. The findings in this study are summarized as follows. (1) The time–area curve of a basin can more realistically be derived by considering both the channel and hillslope velocities. The role of the hillslope velocity can also be easily confirmed by analyzing the derived time–area curve. (2) The analytically derived Clark IUH shows the relative roles of the hillslope velocity and the storage coefficient. Under the condition that the channel velocity remains unchanged, the hillslope velocity controls the runoff peak flow and the concentration time. On the other hand, the effect of the storage coefficient can be found in the runoff peak flow and peak time, as well as in the falling limb of the runoff hydrograph. These findings are also confirmed in the analysis of rainfall–runoff events of the Seolmacheon basin. (3) The effect of the hillslope velocity varies considerably depending on the rainfall events, which is also found to be mostly dependent upon the maximum rainfall intensity.

The present research offers an exploration into the biophilic approach and the role of its agents in urban planning in questions of building a green, resilient urban environment. Biophilia, the innate need of humans to connect with nature, coined by Edgar O. Wilson in 1984, is a concept that has been used in urban governance through institutions, agents’ behaviours, activities and systems to make the environment nature-inclusive. Therefore, it leads to green, resilient environments and to making cities more sustainable. Due to an increasing population, space within and around cities keeps on being urbanised, replacing natural land cover with concrete surfaces. These changes to land use influence and stress the environment, its components, and consequently impact the overall resilience of the space. To understand the interactions and address the adverse impacts these changes might have, it is necessary to identify and define the environment’s components: the institutions, systems, and agents. This paper exemplifies the biophilic approach through a case study in the city of Birmingham, United Kingdom and its biophilic agents. Using the categorisation of agents, the data obtained through in-situ interviews with local professionals provided details on the agent fabric and their dynamics with the other two environments’ components within the climate resilience framework. The qualitative analysis demonstrates the ways biophilic agents act upon and interact within the environment in the realm of urban planning and influence building a climate-resilient city. Their activities range from small-scale community projects for improving their neighbourhood to public administration programs focusing on regenerating and regreening the city. From individuals advocating for and educating on biophilic approach, to private organisations challenging the business-as-usual regulations, it appeared that in Birmingham the biophilic approach has found its representatives in every agent category. Overall, the activities they perform in the environment define their role in building resilience. Nonetheless, the role of biophilic agents appears to be one of the major challengers to the urban design’s status quo and the business-as-usual of urban governance. Researching the environment, focused on agents and their behaviour and activities based on nature as inspiration in addressing climate change on a city level, is an opposite approach to searching and addressing the negative impacts of human activity on the environment. This focus can provide visibility of the local human activities that enhance resilience, while these are becoming a valuable input to city governance and planning, with the potential of scaling it up to other cities and on to regional, national, and global levels.

In this study, we monitor pavement and land subsidence in Tabriz city in NW Iran using X-band synthetic aperture radar (SAR) sensor of Cosmo-SkyMed (CSK) satellites (2017–2018). Fifteen CSK images with a revisit interval of ~30 days have been used. Because of traffic jams, usually cars on streets do not allow pure backscattering measurements of pavements. Thus, the major paved areas (e.g., streets, etc.) of the city are extracted from a minimum-based stacking model of high resolution (HR) SAR images. The technique can be used profitably to reduce the negative impacts of the presence of traffic jams and estimate the possible quality of pavement in the HR SAR images in which the results can be compared by in-situ road roughness measurements. In addition, a time series small baseline subset (SBAS) interferometric SAR (InSAR) analysis is applied for the acquired HR CSK images. The SBAS InSAR results show land subsidence in some parts of the city. The mean rate of line-of-sight (LOS) subsidence is 20 mm/year in district two of the city, which was confirmed by field surveying and mean vertical velocity of Sentinel-1 dataset. The SBAS InSAR results also show that 1.4 km2 of buildings and 65 km of pavement are at an immediate risk of land subsidence.

This study tests stationary and non-stationary approaches for modelling data series of hydro-meteorological variables. Specifically, the authors considered annual maximum rainfall accumulations observed in the Calabria region (southern Italy), and attention was focused on time series characterized by heavy rainfall events which occurred from 1 January 2000 in the study area. This choice is justified by the need to check if the recent rainfall events in the new century can be considered as very different or not from the events occurred in the past. In detail, the whole data set of each considered time series (characterized by a sample size N > 40 data) was analyzed, in order to compare recent and past rainfall accumulations, which occurred in a specific site. All the proposed models were based on the Two-Component Extreme Value (TCEV) probability distribution, which is frequently applied for annual maximum time series in Calabria. The authors discussed the possible sources of uncertainty related to each framework and remarked on the crucial role played by ergodicity. In fact, if the process is assumed to be non-stationary, then ergodicity cannot hold, and thus possible trends should be derived from external sources, different from the time series of interest: in this work, Regional Climate Models’ (RCMs) outputs were considered in order to assess possible trends of TCEV parameters. From the obtained results, it does not seem essential to adopt non-stationary models, as significant trends do not appear from the observed data, due to a relevant number of heavy events which also occurred in the central part of the last century.

Abstract: Many informal settlements in Indonesia have been unable to survive, this is due to changes that occur in the neighborhood. This change resulted in the not surviving of informal settlements, but this did not affect the informal settlements in the city of Palangkaraya, settlements on the banks of the Kahayan river were even more developed, and began to develop towards the mainland.As climate change and the global environment increase, there is a tendency for people to conceptualize adaptation in residential buildings as a process of survival and how adaptation is practiced by people who face the negative impacts of climate change, for example in informal settlements on the Kahayan river bank, where residents adapt to building their homes to be able to withstand environmental changes. Where the neighborhood is located there are tides of the river, as well as other environmental factorsThis study is to find out how the Kahayan River settlement communities can survive, with changes that occur in the environment by analyzing using 6 strategies in building adaptation, namely: Adjustable, Versatile, Refitable, Convertible, Scalable, and Movable (Robert Schmid, 2009). Adaptation that occurs in these settlements, namely on building houses that follow climate change, times, and the environment.Keyword: Informal Settlements, Kahayan River Edge, Adaptation, Transformation.Abstrak: Permukiman Informal di Indonesia banyak yang sudah tidak dapat bertahan, hal ini di karenakan adanya perubahan yang terjadi di lingkungan permukiman tersebut. Perubahan ini berakibat tidak bertahannya permukiman informal, namun hal ini tidak mempengaruhi permukiman informal di Kota Palangkaraya, permukiman yang berada di tepi sungai kahayan ini malah semakin berkembang, dan mulai berkembang menuju ke daratan.Seiring dengan meningkatnya perubahan iklim dan lingkungan global, ada kecenderungan masyarakat untuk membuat konsep adaptasi pada bangunan rumah tinggal sebagai proses untuk bertahan dan bagaimana adaptasi dipraktikkan oleh orang-orang yang menghadapi dampak negatif perubahan iklim, sebagai contoh pada permukiman informal yang berada di tepi sungai Kahayan, di mana warga beradaptasi pada bangunan rumah mereka untuk dapat bertahan terhadap perubahan lingkungan. Di mana lingkungan permukiman ini terdapat pasang surut air sungai, serta faktor lingkungan lainnya.Penelitian ini untuk mengetahui cara masyarakat permukiman tepi Sungai Kahayan dapat bertahan, dengan perubahan yang terjadi di lingkungan dengan menganalisa menggunakan 6 strategi dalam adaptasi bangunan, yaitu: Adjustable, Versatile, Refitable, Convertible, Scalable, dan Movable (Robert Schmid, 2009). Adaptasi yang terjadi pada permukiman ini, yaitu pada bangunan rumah yang mengikuti perubahan iklim, jaman, dan lingkungan.Kata Kunci: Permukiman Informal, Tepi  Sungai Kahayan, Adaptasi, Transformasi.

Architects and designers realize that new buildings cannot completely replace old buildings in the process of urbanization in the world. To establish a method of the new building and the old building coexist and to create the new paradigm of the new building construction in the old district is the responsibility faced by the contemporary architects. This paper first analyzes the old building renovation projects in Berlin and Paris in the 1980s and puts forward the symbiotic relationship between the old and the new buildings in the new era, thus obtaining the research objectives, trying to redefine new buildings and old districts, and creating the new paradigm of contemporary building construction in old districts. Using workshop as an exploration method, this paper conducts data research and sampling analyses on the Chinatown area in Bangkok, and explores the combination mode and paradigm transformation of new buildings and old districts in the city, aiming to seek solutions utilizing art exploration.

Padang City is a city located in the province of West Sumatra, with a very strategic geographical condition, making the city of Padang rich in natural beauty. The beauty of nature is used by people in Padang City as a tourist spot, so that it is able to steal the attention of foreign tourists to come to visit, foreign tourists who enter and leave the Padang City area, all of which are under immigration control. Immigration is a form of enforcement in the implementation of state government sovereignty, therefore to facilitate immigration in carrying out its duties and functions in the supervision sector of foreign visits, a class 1 Padang Immigration office was formed. Since the enactment of Presidential Regulation Number 21 of 2016 regarding Visit Visas in Indonesia, it is clear that 169 countries are free to visit Padang City only with their passports. The purpose of this Presidential Regulation is to increase foreign tourist visits to Padang City so that it has an impact on increasing national development in general and increasing economy in particular, foreign tourists who come are expected to have a positive impact on the economy of the people of Padang City. However, the fact is not as imagined by the Padang City Government, the tourist visit permit granted to foreign tourists is prone to abuse, especially looking for work or opening business land and settling in a place. Researchers took the research location at the Padang Class I Immigration Office, because the city of Padang is one of the most attractive cities to be visited by foreign tourists, especially its natural beauty. As a government effort in order to support the maintenance of stability, security and vigilance against all negative impacts arising from the crossing of people between countries, and the activities of foreigners in Padang City, it is deemed necessary to carry out supervision of foreigners and immigration actions in a fast, thorough, and coordinated manner, without must ignore the openness in providing services to foreigners who are at the Class 1 Padang Immigration Office.
