The city of Sefrou, because of its geographical position, its cultural heritage and urban planning, than economically, is classified as one of the sites with a vulnerability particular to floods. Oued Aggay, the subject of this study, constitutes a danger potential because of the violence of its floods. In this perspective that comes this study that part of the creation and management of a spatial database on flood risk in the Sebou basin. It aims to spatialize the extent of the floods of Oued Aggay and propose solutions to protection the city of Sefrou against floods. The chosen approach goes through a hydrological study, the choice of profiles and the construction of onedimensional model from HEC RAS hydrology software. This study allowed us to simulate floods by statistical methods, identify flood zones and determine the different water levels in the flooded area for the Oued Aggay watershed.

<p>Assessing the risk of future flood events and the implications for flood risk in cities is an economically and socially costly problem. In this research, we assess the utility of documentary evidence of past flood events for contemporary flood risk assessments to reduce the uncertainty in flood frequency estimation due to the interpolation from short annual maximum series (AMS) records.</p><p>The historical city of Bath, United Kingdom, developed in close relation to the River Avon, and evidence of flooding in the city of Bath can be traced back to Roman occupation. For this research a particularly rich record of historical evidence was chosen occurring from the 19<sup>th</sup> century onwards with flood marks on buildings through-out the city as well as documentary evidence in contemporary newspapers and technical reports. The earliest flood mark found in the city of Bath dates to 1823 with 15 more extreme floods after that marked as well. The extensive flooding in 1947 initiated work on what eventually became the present-day Bath flood protection scheme (BFS) which was implemented after the 1960 catalyst flood event.</p><p>Using an existing one-dimensional hydraulic model representing the current hydraulic system of the River Avon in Bath, a historical survey of how the river and its management has changed over time was conducted. The model was developed using historical evidence (e.g. maps, flood marks, photographs, newspaper articles etc), surveyed river cross sections, recorded and design hydrographs from National datasets.</p><p>The 1960 flood is reconstructed numerically using all available data, from flood marks to old surveyed river cross sections.  The resulting hydraulic model is used to investigate the effect of the Bath Flood Defence Scheme. Sensitivity studies with different values for the roughness coefficient are also presented in order to assess the uncertainty on water levels during extreme events. Finally, the numerically reconstructed historical peak flood discharge is compared with the results obtained using a simple Manning equation approach to assess the two methods. This paper demonstrates how hydraulic modelling can be applied to historical data and offers considerable potential to further investigations in the improvement of design flood flows.</p>

On the example of Samara city gradual degradation of cultural heritage associated with the loss of former functionality is viewed. The existing approach to the construction in the historical part of the city secondary development cost-eff ective objects due to replacement of perimeter buildings by island development is analyzed. For the integration of cultural heritage into the secondary development of the urban node with preserving the typological features of historically established urban planning structure the method of alternative reconstruction is proposed. It supposes the preservation of buildings authentic parts and (or) the restoration of lost elements with the possibility of using of contour of the bearing walls as urban environment elements.

This study analyses the extent of the phenomenon of home sharing based on an empirical full examination of Airbnb accommodation in Germany. The subject matter here is both the small-scale implications of renting out residential space and different approaches to regulating short-term rentals under urban planning and housing law. The author also subjects eleven bans on the misappropriation of housing to a comprehensive evaluation in order to test their effectiveness as a regulatory instrument. They can contribute significantly to governing the crowd phenomenon of home sharing. Nevertheless, the use of area-specific instruments is preferable in most cases to the city-wide approach through the law on the misappropriation of housing.

Problem statement. In the modern urban planning practice of development of historical cities the role and potential of the city center are still insufficiently defined, features of its preservation and possible development are not revealed. In Ukraine, there is still no clear definition of the concept of “city center”, which does not contribute to the sustainable urban and architectural development of historic cities. Today there are different interpretations of such an urban category as “city center”. According to the researcher M. Bevz, the “city center” provides a rare opportunity to trace the millennial evolution of the urban planning system, which is rare in Ukraine. Some researchers believe that the city center is an important communication hub and a special space in which various functions of urban life are introduced, in all its evolution, modification, meanings and perceptions (O. Rybchynsky “Formation and revitalization of historical cities of Ukraine”). The author of the study considers it most appropriate to consider the concept of “city center” as identical to the concept of “historical core of the city”. Characteristics of the concept of “historic area of the city” appeared only in 2000 in the Law of Ukraine “On Protection of Cultural Heritage” as part of the settlement, which preserved cultural heritage sites and related planning and form of construction that originate from previous periods of development, typical of certain crops or periods of development. One of the most important methods of preserving and properly modernizing the environment of historical areas should be considered “revalorization”, which contributes to the cultural value of the historic city center. The purpose of the article is to highlight the importance of the historical area as a basis for the formation of interactive recreation. Results. Implementation of revalorization into the theory and practice of domestic reconstruction of the urban environment on the basis of comprehensive and deep theoretical research, as well as ideas for improving and arranging urban space with a focus on successful foreign solutions for using the cultural potential of the central areas of historical cities in the system of interactive recreation. The city should be considered as a multifunctional phenomenon in the diversity of manifestations due to its general cultural and historical significance. In this context, the historic city center is a concentration of interactive communication between residents. Interactive communication is primarily an exchange of ideas for improving the urban environment and enhancing information exchange between people. In such interaction of people and environment of special importance acquires the reflection of human emotional reaction to the made architectural and town-planning environment with its historically formed “human” scale and richness of forms that in turn is necessary protective reaction of the modern person to “standardization” of new city building. The creation of interactive recreation based on the cultural potential of the historic areas of the city allows to form in these areas full-fledged interactive recreational spaces in the combination of existing and new buildings. Scientific novelty and practical significance. Due to the active growth of requirements for the quality and comfort of the urban space of the historic core of the city, the practical significance of the study is to study the historically formed substance of the city, its authenticity; preservation, revival and development of the historical image of the city center on the principles of revalorization. Today there is a need to find and develop methods of activating the environment, one of which is the creation of interactive recreation, which will help to adapt the city-forming and functional significance of their historic areas to new needs.

The concept of multi-sensory perception of cities is one of the elements shaping the complete image of the city. It is an aspect as important to the recipient as the urban structure. The study of the multisensory record of public spaces gives a better chance to understand: the identity of the place, the changing dimensions of cultural heritage, local social problems, and even conditions influencing spatial decisions. Multisensory research has an implementation value and can be an important, previously unaccounted for factor, influencing the revitalization program and planning decisions. Therefore, it is so important to analyze the available literature on the subject, conduct scientific observation of the research area, create a proposal for a hybrid research methodology on multi-sensory recording of space and determine their relationship with activities in the field of urban planning. The trial area – selected public spaces of the Praga – Północ district in Warsaw was adopted according to predetermined criteria, the most important of which were: authentic urban tissue, downtown area, architectural and functional diversity of buildings.

We examine the current architectural and urban planning approaches towards preservation and regeneration of historical and cultural values represented by watercourses in the urban structure of the city. Using the examples of two Slovak cities Košice and Prešov, the paper highlights the need for preservation and conservation of the watercourse corridors in the urban structure, even in the cases without the contemporary presence of water, as they represent significant cultural and historical values. Their preservation in the contemporary urban structure creates a base for the possibility of their future revitalization with the recovery of water, or the possibility of their future use as attractive tourist, pedestrian, bicycle, andgreen corridors with recreational and environmental functions.

This paper discusses the concept of “roughness” as the driving principle in the analysis of the rela‑ tionship between tourism development and built cultural heritage. It’s a theoretical reflection of an exploratory and descriptive nature that aims at synthesizing existing knowledge while providing new interpretative and analytical guidelines. Working from previous studies it was possible to identify the dialectics of the relationship between cultural heritage and tourism development with perspectives centering on two classification catego‑ ries, their intrinsic value and their market value. The study presents a re‑think of the concepts of roughness and heritage used in urban planning aimed at re‑interpreting urban space for tourism, re‑appraising their possible application to heritage sites in the city. The results may open up new perspectives for urban planning and roughness and balance out the advantages and disadvantages of re‑working the city space for tourism.

Today, there is a need to assess the historical development of small cities in Russia in order to identify urban planning conflicts in the urban environment and determine promising directions for their resolution. This study is aimed at analyzing existing urban planning conflicts and disclosing the resource potential of the territory of historical buildings in the center of a small town on the example of Valuyki, Belgorod region. The authors uses conflictological and complex approaches. The analysis of the planning, functional and transport structure of the city is carried out. The analysis of the cultural heritage objects of the historical center based on historical and cultural reference plan of the city center is compiled. The current state of the riverside territories of the river Valuy in the central part of the city has been reviewed. A number of urban-ecological conflicts leading to the degradation of the coastal zone have been identified. Urban planning conflicts of the city center (social-functional, land-use, transport, etc.) are also identified and classified, their types are determined by the type of location (linear, point, areal), their participants and possible directions for their solution are identified. The promising directions of the development of the historical center of the city and the likelihood of the emergence of new types of activities for cultural heritage sites have been determined.
