Drainage System of Tegalsari Polder for Handling Flood and Tide in Tegal City Indonesia

Although in 2019 the local government of Tegal city Indonesia had constructed a retention basin at drainage system of Siwatu, Tegal Barat, Tegal city with a catchment area of 226 ha, the areas around the system still experienced flood and inundation. This study belonged to a descriptive qualitative research aimed to evaluate the performances of Siwatu drainage system and Tegalsari retention basin. Data of the study included field data and technical data from institutions. Based on the 15-year rainfall data (2014 – 2018) from Pemali - Comal PSDA Office, Central Java Province, Indonesia, the statistical parameters of Cs: 0.0027, Ck: 1.904, Sd: 15.91, Cv: 0.144 were obtained and so Gumbel method distribution was applied in the study, the return period rainfall of 10 years was 138 mm, the flood discharge for Qr.10 years was 9.63 m3/sec., the addition of long storage was 8×2,50×500 m, and the combination of pump addition was of 1 m3/sec. with the long storage of 8×2.00×500 m. By implementing one of the alternative choices, either flood or inundation could be resolved.

Knowledge platforms addressing nature-based solutions for climate change adaptation and disaster risk reduction at European and national levels

Research results of a new governance method in climate adaptation

Cities are becoming increasingly vulnerable to climate change and there is an urgent need to become more resilient. This research involves the development of the City Climate Scan methodology to measure, map, scan and assess different parameters that provide insight into the vulnerability of urban areas and neighborhoods. The research involved the development of a set of measurement tools that can be applied in different urban neighborhoods in a low-cost low-tech approach with teams of stakeholders and practitioners. The City Climate Scan method was tested in different cities around the globe with groups of young professionals and stakeholders in rapid urban appraisals.For the Rotterdam City Climate Scan (September 2017), the following challenges were selected: risk of flooding, heat stress, water quality (micro-pollutants and plastic waste) and air quality. The Rotterdam climate scan is evaluated with their triple helix partners (public, private and academic partners). The conclusion is that the City Climate Scan approach helps policy makers and practitioners to gather valuable data for decision makers in a rapid appraisal at the neighborhood and city level. The results of the City Climate Scan methodprovides insights, creates awareness and brings together stakeholders. The most valuable deliverable is the concrete and tangible results. The participatory approach brings residents and practitioners together and provides insight into local problems, while at the same time the method facilitates the collection of valuable data about the robustness of neighborhoods. As a result of this positive evaluation, the City Climate Scan will be up scaled to a number of cities in Europe and Asia in the upcoming months.

The climate is right up your street

In this book of examples we present possible implementations of straightforward and manageable climate-resilient ideas and options for residential streets. Examples from ordinary Dutch street views show how climate resilience can be implemented with simple solutions and how this does not need to be more costly than traditional measures, particularly in flat areas (such as we often find in the Netherlands). This observation is based on comparative studies across various Dutch cities. We hope that the examples will inspire you to find ways to implementclimate-resilient measures in your city, because the climate is right up your street.

Effective strategies to promote the relevance of the urban subsurface

Innovatieve klimaatstresstest Fryslân

In het kader van klimaatsverandering is het van groot belang om inzicht te krijgen in de impact van intensievere buien, langdurige droogte en hitte dat grote effecten kan hebben op de economie en kwaliteit van de leefomgeving. Om deze reden hebben diverse projectpartners en Fries Bestuursakkoord WaterKeten (FBWK) met de doelgroep (water)wethouders en ambtenaren van de Friese gemeenten samengewerkt aan de volgende vragen in de Friese regio: - Hoeveel schade ondervindt de regio bij een flinke bui? - Waar bevinden zich hitte-eilanden in de gebouwde omgeving in Friesland? - Welke maatregelen kunnen we nemen om de negatieve effecten van klimaatverandering te voorkomen en welke middelen zijn hiervoor nodig? Dit project leverende de volgende producten op: Wateroverlastkaart (WOLK), hittestresskaart, kennisclips, expertkaart die werden besproken bij diverse masterclasses klimaatadaptatie. Met deze producten is inzicht verkregen in de toekomstopgave ten aanzien van het klimaatbestendig maken van de regio en in de mogelijke schade en benodigde middelen om dit te voorkomen.
