Comparative Analysis of Flooding in Gothenburg, Sweden and Mumbai, India: A Review

To cope with flooding in cities, a combination of well working stormwater system and a resilient city is needed. As the future is uncertain, cities have to be built resilient, meaning that they can be flexible and adaptable, as it is not possible to protect the city from floods totally. Green areas in the city can provide resilience, as water can be led here e.g. during heavy rainfall. In this article the situation in Gothenburg, which is on the list of Swedish cities at risk of getting flooded, and Mumbai, where parts of the city is flooded every monsoon season, are compared. The sewage systems in Mumbai and Gothenburg were built in the same time period, late 1800’s and early 1900’s, both with British influences. The system in Mumbai has, more or less, not been developed since it was built, while the Gothenburg system has been developed along with the city expansion. Many parts of both cities were built on former marshland areas, close to the sea. Our recommendation, for both cities, is to develop the storm water systems further with sustainability and resilience perspectives in mind, including to build floodable areas close to the city centre. It is also important to educate leaders and practitioners in both cities about resilience and sustainability perspectives

Combined effects of high water level and precipitation on flooding of Gothenburg, Sweden

In the future, both rising sea water level and higher precipitation are expected due to climate change. Gothenburg is one of the cities in Sweden most affected by flooding in urban areas. Flooding is caused by very high sea level, but also as a consequence of heavy rainfall over the city. It is unknown whether high sea level or heavy rainfall is the most important reason for flooding, or if the combination of them causes the most severe flooding. Flooding caused by combinations of extreme water levels and rains in Gothenburg, are simulated using Mike21 for two scenarios: present climate and year 2100. A digital elevation model is used as input together with water level data from the harbour (Torshamnen) and CDS-rainfall (Chicago Design Storm). In present climate, extreme rainfall and extreme sea water level give more or less the same amount of flooding. If a greater part of Gothenburg is taken into account, extreme precipitation is expected to be the most important factor. In year 2100, the area along the harbour is flooded more severely by a 100-year water level, as the level of the quay is exceeded. In future climate, flooding from sea surge will cause more severe flooding

Kommunens behov av en yngre livspartner – En kvalitativ studie om hur organisationen arbetar med att utveckla och behålla unga talanger

De stora pensionsavgångar som offentlig sektor står inför innebär att 4 av 10 chefer når pension inom snar framtid. En grundläggande förutsättning för en fortsatt utveckling av välfärden blir därmed tillgången på unga medarbetare vilka har potential att överta dessa chefspositioner. För att fylla de positioner samt behålla unga medarbetare som besitter rätt kompetens och hög potential måste organisationer inom offentlig sektor möta deras behov. Samtidigt måste de unga talanger som besitter denna potential utvecklas och förses med rätt förutsättningar i syfte att axla rollen som framtidens chefer. Uppsatsens syfte är att skapa förståelse för hur organisationer använder Talent Management-strategier för att utveckla och behålla unga talanger samt hur de kan möta den unga generationens krav på sina arbetsgivare. I denna uppsats antas en kvalitativ metod i syfte att fördjupa vår förståelse av organisationers arbete med att utveckla och behålla unga talanger. Insamlingen av empiriskt material gjordes utifrån en fallstudie av Helsingborgs Stad där semistrukturerade intervjuer genomfördes med både ledning och unga medarbetare. Vi kan konstatera att det inte finns en övergripande strategisk plan för att utveckla och behålla unga talanger i Helsingborgs stad. Kommunen har en god bild av de behov som den unga generationen har där det finns en strategisk inriktning som syftar till att möta dessa. Bristen på en övergripande plan resulterar i organisatoriska utmaningar vilka påverkar arbetet med att behålla och utveckla unga talanger

A data management framework for strategic urban planning using blue-green infrastructure

Spatial planning of Blue-Green Infrastructure (BGI) should ideally be based on well-evaluated and context specific solutions. One important obstacle to reach this goal relates to adequate provisioning of data to ensure good governance of BGI, i.e., appropriate planning, design, construction, and maintenance. This study explores the gap between data availability and implementation of BGI in urban planning authorities in Sweden. A multi method approach including brainstorming, semi-structured interviews with urban planners and experts on BGI and Geographical Information System (GIS), and validating workshops were performed to develop a framework for structured and user-friendly data collection and use. Identified challenges concern data availability, data management, and GIS knowledge. There is a need to improve the organisation of data management and the skills of trans-disciplinary cooperation to better understand and interpret different types of data. Moreover, different strategic goals require different data to ensure efficient planning of BGI. This calls for closer interactions between development of strategic political goals and data collection. The data management framework consists of three parts: A) Ideal structure of data management in relation to planning process, data infrastructure and organisational structure, and B) A generic list of data needed, and C) The development of structures for data gathering and access. We conclude that it is essential to develop pan-municipal data management systems that bridge sectors and disciplines to ensure efficient management of the urban environment, and which is able to support the involvement of citizens to collect and access relevant data. The framework can assist in such development

Management of urban floods based on tolerable consequences in an uncertain future

Precipitation is intrinsically associated with high uncertainty, which is exacerbated exponentially over time—especially concerning climate change. However, the current design practice in urban drainage infrastructure remains firmly bound to deterministic assumptions regarding the design load. This approach is too simplified—focusing only on the return period of the design event—and ignores the complexity of drainage systems, the potential changes in catchment hydrology and the at-risk valuable assets within. Therefore, the current design approach is inherently an unsustainable practice that cannot deal with extreme uncertainties associated with urban drainage and flood resilience in changing climate and society. This paper examines the current deterministic design practice and encourages a collective discussion on the need for a paradigm shift in the engineering of pluvial floods toward a risk-based design. We believe that adopting a risk-based design will partially address the uncertainty and complexity of climate and urban drainage, respectively, although a method for the new practice in a risk-based design paradigm must be developed
