Natural hazards’ information is an obligatory element of planning acts in Poland, such as areas exposed to mass movements and flood occurrence. The paper presents provisions and manners applied in urban planning and design practise in Lesser Poland (Małopolska), region with vast share of landslides in Poland. Discussion leads to evaluation of risk management legal factors in design process, urban planning and accomplishment of building permission.

AbstractThe study of hillslopes has been dominated by the expansion of studies into process rates and mechanisms. Perhaps the greatest volume of work has been on the ‘wash’ processes of soil erosion, but there has also been significant work on the diffusive mass movements of linear and non-linear ‘creep’ that shape the convexity of hilltops, on more rapid mass movements and on solution processes. There has also been fresh work on distinctive processes in coastal, arid and cold-climate environments.Accompanying and integrated with process understanding, and made possible by ubiquitous computational power, modelling has developed from soluble mathematical simplifications to complex simulations that incorporate much of our understanding of process and climate.Particular topics that have seen significant advance include a more complete understanding of drainage density and texture, and a broadening of interest to encompass the ‘critical zone’ that constructively unifies the land surface with the lower atmosphere, the biosphere and the regolith. There has also been a change of focus towards steeplands, dominated by mass movements, supply limited removal and tectonic activity.Most recently, and now incorporated into the concept of the ‘Anthropocene’, human impact is now receiving increasing attention as we acknowledge its accelerating role in changing landscapes and their relationships.

Two Stages

Os territórios de riscos de desastres são considerados, por diversos especialistas, resultados da associação entre exposição aos perigos naturais do ambiente, condições de vulnerabilidade social e entre as vulnerabilidades intrínsecas à Gestão de Riscos de Desastres. Tais territórios podem e estão sendo objetos de estudo de pesquisadores de diferentes áreas do conhecimento, inclusive da Geografia. O presente trabalho tem como objetivo caracterizar a exposição de comunidades do município de Alagoa Nova - PB aos riscos de movimentos de massa e alagamento. A metodologia está dividida em duas etapas, as quais possuem, em comum, os seguintes procedimentos: levantamento bibliográfico, levantamento de dados secundários, elaboração cartográfica, atividades de campo e diálogo com representante da Defesa Civil Municipal. Coloca-se como relevante à medida que os seus resultados conseguem apontar os fatores que devem ser priorizados pela Defesa Civil Municipal e por outras secretarias municipais para uma efetiva mitigação dos riscos nas comunidades. Diagnostic of Exposure to Risks of Mass Movement and Flooding in Communities of the Municipality of Alagoa Nova, Paraíba / BrazilA B S T R A C TDisaster risk territories are considered by various experts to be the result of the association between exposure to natural environmental hazards, conditions of social vulnerability, and intrinsic vulnerabilities to Disaster Risk Management.

Inundation Modeling

In recent decades, natural hazards have caused major disasters in natural and man-made environments. Floods are one of the most devasting natural hazards, with high levels of mortality, destruction of infrastructure, and large financial losses. This study presents a methodological approach for flood risk management at lakes and adjacent areas that is based on the implementation of the EU Floods Directive (2007/60/EC) in Greece. Contemporary engineering approaches have been used for the estimation of the inflow hydrographs. The hydraulic–hydrodynamic simulations were implemented in the following order: (a) hydrologic modeling of lake tributaries and estimation flood flow inflow to the lake, (b) flood inundation modeling of lake tributaries, (c) simulation of the lake as a closed system, (d) simulation of the lake outflows to the adjacent areas, and (e) simulation of flood inundation of rural and urban areas adjacent to the lake. The hydrologic modeling was performed using the HEC-HMS model, and the hydraulic-hydrodynamic simulations were implemented with the use of the two-dimensional HEC-RAS model. The simulations were applied to three soil moisture conditions (dry, medium and wet) and three return periods (T = 50, T = 100 and T = 1000 years) and a methodology was followed for the flood inundation modeling in urban areas. Upper and lower estimates on water depths, flow velocities and inundation areas are estimated for all inflow hydrographs and for varying roughness coefficient values. The proposed methodology presents the necessary steps and the results for the assessment of flood risk management and mapping for lake and adjacent urban and rural areas. The methodology was applied to Lake Pamvotida in Epirus, Greece, Ioannina.
