Efficiency of sustainable urban drainage systems during flash floods / Effektivitet av hållbara dagvattensystem vid skyfall

Axelsdóttir, Snærós January 2022 (has links)
As the world’s population is migrating more into urban areas, landcover changes follow. Natural pervious areas are being converted to impervious areas, which when subjected to rain generates more stormwater runoff. Stormwater management is a problem that cities today are challenged with, infrastructure is getting older and precipitation patterns are changing due to climate change. Due to climate change extreme precipitation events are likely to increase and therefore increase the probability of urban flooding. Urban flooding can be caused by extreme precipitation events with a short duration, or so-called flash floods. These flash floods can overwhelm the drainage system in place which therefore can cause flooding. This problem has inspired engineers to rethink stormwater management, moving from traditional grey drainage systems to more green and sustainable drainage systems. Sustainable Urban Drainage System (SuDS) are drainage systems that aim to regain the properties of non-urbanised areas, retain the natural hydrological cycle, and have recreational values for the surrounding societies. This study investigated how different SuDS behave when subjected to flash floods. A model of a synthetic case study was built in the Storm Water Management Model (SWMM) and sustainable urban drainage systems implemented. The solutions investigated were bioretention cells, rain gardens, infiltration trenches, green roofs, and permeable pavements. Three different rain events were analysed, all with different precipitation depth but with the same duration of 1 hour. Results showed that bioretention cells could reduce runoff volumes to the highest extent while green roofs could reduce the peak runoff the most. Other results were analysed like efficiency and cost. Bioretention cell came out on top in efficiency but had the highest cost. Overall, all the solutions showed promise in reducing runoff during flash floods, but the reduction capacity goes down with increased precipitation. / När en större del av världens befolkning flyttar in till tätortsområden så medföljer en ändring av markytans beskaffenhet. Vanligtvis genomträngliga ytor omvandlas till hårdgjorda ytor vilket generar mer dagvattenavrinning när de utsätts för regn. Dagvattenhanteringen är en utmaning för många städer idag eftersom infrastrukturen blir äldre och nederbördsmönstren förändras på grund av klimatförändringar. Extrema nederbördshändelser väntas öka med anledning av dessa klimatförändringar och ökar därigenom sannolikheten för översvämningar i städer. Översvämningar i städer kan orsakas av korta nederbördshändelser med hög intensitet, så kallade Skyfall, vilket kan överbelasta dagvattensystemets kapacitet. Det har lett till att ingenjörer ändrat sitt tankesätt på hur dagvatten ska hanteras och börjat gå från konventionella till mer gröna och hållbara dräneringssystem. Hållbar dagvattenhantering är dräneringssystem som syftar till att använda egenskaperna hos naturliga områden, behålla det naturliga hydrologiska kretsloppet och skapa rekreationsvärden för de omkringliggande samhällena. Denna studie har undersökt hur olika hållbara dräneringssystem beter sig när de utsätts för översvämningar. En modell på en syntetisk fallstudie byggdes i Storm Water Management Model (SWMM) där hållbara dräneringssystem implementerades i en urban miljö. Lösningarna som undersöktes var biofilterbäddar, regnträdgårdar, infiltrationsbäddar, gröna tak och permeabla trottoarer. Tre olika nederbördshändelser analyserades, alla med olika nederbördsmängder men med samma varaktighet på en timme. Resultaten visade att biofilterbäddar kunde minska avrinningsvolymerna i största grad medan gröna tak minskade ytavrinningen mest. Effektivitet och kostnad analyserades också. Där visade biofilterbäddarna högst effektivitet men hade den högsta kostnaden. Sammantaget visade det sig att alla lösningar var lovande vad gäller minskning av avrinning under översvämningar, men reduktionskapaciteten minskar med ökad nederbörd.

Development of Treatment Train Techniques for the Evaluation of Low Impact Development in Urban Regions

Hardin, Mike 01 January 2014 (has links)
Stormwater runoff from urban areas is a major source of pollution to surface water bodies. The discharge of nutrients such as nitrogen and phosphorus is particularly damaging as it results in harmful algal blooms which can limit the beneficial use of a water body. Stormwater best management practices (BMPs) have been developed over the years to help address this issue. While BMPs have been investigated for years, their use has been somewhat limited due to the fact that much of the data collected is for specific applications, in specific regions, and it is unknown how these systems will perform in other regions and for other applications. Additionally, the research was spread across the literature and performance data was not easily accessible or organized in a convenient way. Recently, local governments and the USEPA have begun to collect this data in BMP manuals to help designers implement this technology. That being said, many times a single BMP is insufficient to meet water quality and flood control needs in urban areas. A treatment train approach is required in these regions. In this dissertation, the development of methodologies to evaluate the performance of two BMPs, namely green roofs and pervious pavements is presented. Additionally, based on an extensive review of the literature, a model was developed to assist in the evaluation of site stormwater plans using a treatment train approach for the removal of nutrients due to the use of BMPs. This model is called the Best Management Practices Treatment for Removal on an Annual basis Involving Nutrients in Stormwater (BMPTRAINS) model. The first part of this research examined a previously developed method for designing green roofs for hydrologic efficiency. The model had not been tested for different designs and assumed that evapotranspiration was readily available for all regions. This work tested this methodology against different designs, both lab scale and full scale. Additionally, the use of the Blaney-Criddle equation was examined as a simple way to determine the ET for regions where data was not readily available. It was shown that the methods developed for determination of green roof efficiency had good agreement with collected data. Additionally, the use of the Blaney-Criddle equation for estimation of ET had good agreement with collected and measured data. The next part of this research examined a method to design pervious pavements. The water storage potential is essential to the successful design of these BMPs. This work examined the total and effective porosities under clean, sediment clogged, and rejuvenated conditions. Additionally, a new type of porosity was defined called operating porosity. This new porosity was defined as the average of the clean effective porosity and the sediment clogged effective porosity. This porosity term was created due to the fact that these systems exist in the exposed environment and subject to sediment loading due to site erosion, vehicle tracking, and spills. Due to this, using the clean effective porosity for design purposes would result in system failure for design type storm events towards the end of its service life. While rejuvenation techniques were found to be somewhat effective, it was also observed that often sediment would travel deep into the pavement system past the effective reach of vacuum sweeping. This was highly dependent on the pore structure of the pavement surface layer. Based on this examination, suggested values for operating porosity were presented which could be used to calculate the storage potential of these systems and subsequent curve number for design purposes. The final part of this work was the development of a site evaluation model using treatment train techniques. The BMPTRAINS model relied on an extensive literature review to gather data on performance of 15 different BMPs, including the two examined as part of this work. This model has 29 different land uses programmed into it and a user defined option, allowing for wide applicability. Additionally, this model allows a watershed to be split into up to four different catchments, each able to have their own distinct pre- and post-development conditions. Based on the pre- and post-development conditions specified by the user, event mean concentrations (EMCs) are assigned. These EMCs can also be overridden by the user. Each catchment can also contain up to three BMPs in series. If BMPs are to be in parallel, they must be in a separate catchment. The catchments can be configured in up to 15 different configurations, including series, parallel, and mixed. Again, this allows for wide applicability of site designs. The evaluation of cost is also available in this model, either in terms of capital cost or net present worth. The model allows for up to 25 different scenarios to be run comparing cost, presenting results in overall capital cost, overall net present worth, or cost per kg of nitrogen and phosphorus. The wide array of BMPs provided and the flexibility provided to the user makes this model a powerful tool for designers and regulators to help protect surface waters.

A Comparative Study of Three Growing Media and Four Plant Groups Under Extensive Green Roof Conditions in San Luis Obispo, CA

Nelson, Todd Alan 01 July 2010 (has links) (PDF)
ABSTRACT A Comparative Study of Three Growing Media and Four Plant Groups Under Extensive Green Roof Conditions in San Luis Obispo, California Todd A. Nelson Green roof growing media and plant species are critical factors when deciding on the best materials for a project. Growing media must be chosen in accordance with load bearing capacities of structures and water requirements of the plant material. Plant species must be able to thrive in the climate of the green roof and withstand a green roof’s harsh environment. The objectives of this research were: (1) to determine which of three extensive green roof growing media support the most growth of Sedum, a proven extensive green roof plant genus; and (2) to determine which of four plant groups provides the most media coverage under extensive green roof conditions. Sedum growing in a granular growing media blend with higher organic matter and larger particles provided more coverage than Sedum growing in a medium with smaller particles with lower organic matter and an experimental foam medium. Sedges covered the soil faster than Sedum, grasses, and Mediterranean species. These results will help green roof designers and landscape architects anticipate the plant growth rates during the first 36 weeks of new projects and choose more effective growing media blends. They can also observe the growth patterns of the plant groups to choose plant material that will achieve the functional objectives of a green roof more efficiently. These results are applicable to green roofs designed for moderate California coastal climates and regions with similar weather conditions.
