Design Values

Climate change has a significant impact on many sectors, including water management. A very important parameter in the designing of water management objects and systems (for example sewers, water retention facilities etc.) is rainfall intensity, which expresses the amount of precipitation per time. In Slovakia, the design values of rainfall intensities from 1973 are still in use. These values are outdated and probably currently unsatisfactory. This paper is focused on analysis of observed rainfall intensities in the territory of Eastern Slovakia. Observed rainfall data of 10 minutes’ rainfall for time period 2000-2018 was compared to design values of rainfall intensities from 1973. The data from two rainfall station Poprad and Košice were considered. In the paper, there are compared observed (measured) and designing rainfall intensities for the duration of rain 10, 30 and 60 minutes.

Monthly Runoff

<p>Water scarcity is increasingly becoming a problem in many regions of the world. On the one hand, this can be attributed to changes in precipitation conditions due to climate change. On the other hand, this is also due to population growth and changes in consumer behaviour. In this study, an analysis is carried out for the highly glaciated Vilcanota River catchment (9808 km<sup>2</sup> – 1.2% glacier area) in the Cusco region (Peru). Possible climatic and socioeconomic scenarios up to 2050 were developed including the interests from different water sectors, i.e. agriculture, domestic and energy.</p><p>The analysis consists of the hydrological simulation at a monthly time step from September 2043 to August 2050 using a simple glacio-hydrological model. For historic conditions (1990 to 2006) a combination of gridded data (PISCO precipitation) and weather stations was used. Future scenario simulations were based on three different climate models for both RCP 2.6 and 8.5. Different glacier outlines were used to simulate changes in glacier surface through the time for both historic (from satellite data) and future (from existing literature) scenarios. Furthermore, future water demand simulations were based on the SSP1 and SSP3 scenarios.</p><p>Results from all scenarios suggest an average monthly runoff of about 130 m<sup>3</sup>/s for the Vilcanota catchment between 2043 and 2050. This represents a change of about +5% compared to the historical monthly runoff of about 123 m<sup>3</sup>/s. The reason for the increase in runoff is related to the precipitation data from the selected climate models. However, an average monthly deficit of up to 50 m<sup>3</sup>/s was estimated between April and November with a peak in September. The seasonal deficit is related to the seasonal change in precipitation, while the water demand seems to have a less important influence.</p><p>Due to the great uncertainty of the modelling and changes in the socioeconomic situation, the data should be continuously updated. In order to construct a locally sustainable water management system, the modelling needs to be further downscaled to the different subcatchments in the Vilcanota catchment. To address the projected water deficit, a new dam could partially compensate for the decreasing storage capacity of the melting glaciers. However, the construction of the dam could meet resistance from the local population if they cannot be promised and communicated multiple uses of the new dam. Sustainable water management requires the cooperation of all stakeholders and all stakeholders should be able to benefit from it so that they will support future projects.</p>

Integrated Approaches

The article provides an overview of spatial and legal solutions related to the issue of water management in cities in the context of climate change. The aim of the research is to identify the main differences between the traditional and integrated approaches to water-related infrastructure based on case studies of European Cities at different scales. Gathering, ordering and comparing adequate solutions will allow to establish guidelines for the development of Polish cities and point out directions for architects and urban planners designing urban spaces. The comparison of good examples with theory would make it possible to verify whether practise corresponds with theory, and whether it can actually - through the synergy of measures – bring new quality to urban areas.

The Impact

<p>Due to climate change, the water cycle is changing which requires to adapt water management in many regions. The transdisciplinary project KlimaRhön aims at assessing water-related risks and developing adaptation measures in water management in the UNESCO Biosphere Reserve Rhön in Central Germany. One of the challenges is to inform local stakeholders about hydrological hazards in in the biosphere reserve, which has an area of only 2433 km² and for which no regional hydrological simulations are available. To overcome the lack of local simulations of the impact of climate change on water resources, existing simulations by a number of global hydrological models (GHMs) were evaluated for the study area. While the coarse model resolution of 0.5°x0.5° (55 km x 55 km at the equator) is certainly problematic for the small study area, the advantage is that both the uncertainty of climate simulations and hydrological models can be taken into account to provide a best estimate of future hazards and their (large) uncertainties. This is different from most local hydrological climate change impact assessments, where only one hydrological model is used, which leads to an underestimation of future uncertainty as different hydrological models translate climatic changes differently into hydrological changes and, for example, mostly do not take into account the effect of changing atmospheric CO<sub>2</sub> on evapotranspiration and thus runoff.   </p><p>The global climate change impact simulations were performed in a consistent manner by various international modeling groups following a protocol developed by ISIMIP (ISIMIP 2b, www.isimip.org); the simulation results are freely available for download. We processed, analyzed and visualized the results of the multi-model ensemble, which consists of eight GHMs driven by the bias-adjusted output of four general circulation models. The ensemble of potential changes of total runoff and groundwater recharge were calculated for two 30-year future periods relative to a reference period, analyzing annual and seasonal means as well as interannual variability. Moreover, the two representative concentration pathways RCP 2.6 and 8.5 were chosen to inform stakeholders about two possible courses of anthropogenic emissions.</p><p>To communicate the results to local stakeholders effectively, the way to present modeling results and their uncertainty is crucial. The visualization and textual/oral presentation should not be overwhelming but comprehensive, comprehensible and engaging. It should help the stakeholder to understand the likelihood of particular hazards that can be derived from multi-model ensemble projections. In this contribution, we present the communication approach we applied during a stakeholder workshop as well as its evaluation by the stakeholders.</p>

This paper evaluates the response of streamflow in a Mediterranean medium-scaled basin under land-use and climate change scenarios and its plausible implication on the management of Boadella–Darnius reservoir (NE Spain). Land cover and climate change scenarios supposed over the next several decades were used to simulate reservoir inflow using the Regional Hydro-Ecologic Simulation System (RHESsys) and to analyze the future impacts on water management (2021–2050). Results reveal a clear decrease in dam inflow (−34%) since the dam was operational from 1971 to 2013. The simulations obtained with RHESsys show a similar decrease (−31%) from 2021 to 2050. Considering the ecological minimum flow outlined by water authorities and the projected decrease in reservoir’s inflows, different water management strategies are needed to mitigate the effects of the expected climate change.

Annual Reports

This study examines the nature and extent of climate change disclosures in the corporate annual reports of the listed companies in Dhaka Stock Exchange, Bangladesh. For this purpose, annual reports related to the year 2014 of the sample 88 listed companies have been scrutinized. In regard to this study, content analysis approach has been conducted considering thirteen different disclosure issues regarding climate change. Our analysis provides the comprehension of below average climate change disclosure practices by the Bangladeshi companies, though 58 percent companies have reported at least one issue on climate change and global warming. ‘Energy saving & efficiency’ and ‘water management & pollution’ are mostly reported issues that are industry specific requirements in some case. From the viewpoint of industry, Banking industry and Cement industry have started to report some issues related to the climate change, where 4 industries out of selected 17 industries have not provided any climate change disclosure. Disseminating climate change disclosure within 10 sentences by most of the reported companies manifests the desideratum of in-depth disclosure practices.
