GirişSu kaynaklarının miktar ve kalite açısından yeterli olmaması ve artan nüfus, gelişen sanayi ve tarım faaliyetleri sonucu arazi kullanımında meydana gelen değişiklikler ile ortaya çıkan sorunlar, su kaynaklarının en iyi şekilde yönetilmesi gerektiğini ortaya koymaktadır. Özellikle orman arazilerinin ve sulak alanların yok olması, tarım, yerleşim ve endüstri alanlarının kontrolsüz ve hızlı gelişimi, su kaynakları için ciddi risk oluşturmaktadır. Su kaynaklarının korunması için havza yönetiminin en iyi şekilde yapılması ve havza veriminin değerlendirilmesi gerekmektedir. Havza yönetimi ile birlikte erozyon, sel ve taşkınların önlenmesi, su kirliliğinin engellenmesi, toplumun ihtiyaçlarını karşılayacak miktar ve kalitede su üretilmesi, havzadaki doğal kaynakların planlanması kısacası çevresel sürdürülebilirliğin sağlanması için çeşitli çalışmaların yapılması gerekmektedir.Yağmur suyu yönetimine yönelik uygulamalar 1940'lardan beri dünyada yapılmaktadır. Fakat yapılan bu çalışmalar, genellikle büyük havzalarda ve çoğunlukla taşkın kontrolüne yönelik yönetim çalışmalarıdır. Bununla birlikte özellikle son 20 yıllık dönemde dünyada, kentleşme sonucu kuru havada yüzeyde biriken ve yağış sonucu oluşan yüzeysel akış ile birlikte yıkanıp su kaynaklarına karışan kirliliğin küçük ölçekli bölgelerde önlenmesi için çeşitli çalışmalar başlatılmıştır. Bu çalışmalar ile su miktarının kontrol altına alınarak taşkın gibi olumsuz etkilerinin azaltılması ve su kirliliğinin önlenmesi hedeflenmiştir. Çevre, ekoloji ve mühendislik bilimlerini bir araya getiren ve EİYU arasında olan bu çalışmalar ülkemizde de önem kazanmakta olan çalışmalardır.

Root-enhanced Infiltration in Stormwater Bioretention Facilities in Portland, Oregon

I evaluated the effectiveness of plant roots to increase infiltration rates within stormwater bioretention facilities (SBFs), roadside planter compartments that filter stormwater. SBFs attenuate harmful effects of stormwater by reducing peak flow and retaining pollutants, with increased infiltration that improves both these functions.Researchers have shown that roots can increase infiltration within greenhouse, lab, field, and test SBF settings. However, no researchers have yet measured either the extent to which different root characteristics can increase infiltration or the variation in root characteristics and their effect on infiltration rates among plant assemblages within currently functioning SBFs.To determine if root-enhanced infiltration was occurring within SBFs, I This work strongly suggests plant roots increase infiltration, and thus the primary functions of SBFs. Different root characteristics appear to increase infiltration rate at different depths. Data also show larger-root biomass plants increase infiltration rate to a greater degree than smaller-root biomass plants.I recommend considering several site and facility characteristics when determining the potential for root-enhanced infiltration. When selecting plant species to enhance infiltration, I recommend using several criteria, determining root characteristic iii values at certain depths, considering installation approaches, and accounting for regional climate changes.iv Acknowledgements

“…First developed in the early 1990's, bioretention is now one of the most popular LID stormwater control measures (SCMs) in the United States and Australasia as research has demonstrated success in meeting both hydrologic and water quality goals in laboratory and field settings [5][6][7][8][9][10]. Bioretention cells (BRCs) are a (depressed) landscape feature; underlying the landscape is engineered filter media, and in many cases, an underdrainage system [9].…”

A Retrospective Comparison of Water Quality Treatment in a Bioretention Cell 16 Years Following Initial Analysis

One of the most popular stormwater practices in (sub-)urban North Carolina is bioretention. While bioretention has been researched intensively to determine the most efficient designs, few long-term studies have attempted to assess the performance of older bioretention. However, previous research and design guidance for bioretention has predicted long-term water quality treatment. This study compared discharged concentrations and loads of nitrogen and phosphorus from a bioretention cell (1) post-construction and (2) following 17 years of treatment. A conventionally-drained bioretention cell with lateral underdrains in Chapel Hill, North Carolina, USA, was first monitored post-construction for 10-months from 2002–2003 and, again following continuous use, for 14 months from 2017–2018. Estimated mass load reductions during the initial monitoring period were 40% for total nitrogen (TN) and 65% for total phosphorus (TP). Mass load reductions were increased 17 years after construction, with reductions of 72% and 79% for TN and TP, respectively. Plant growth, death, and decay over the 17-year life of the bioretention cell are hypothesized to have contributed additional nitrogen assimilation and carbon to the fill media, serving as a catalyst for nitrogen treatment. Phosphorus removal remained relatively unchanged between the two monitoring periods. Filter media samples indicated the top 20 cm of filter media were nearing phosphorus saturation, but with 1.2 m of filter media, lower depths would most likely continue to provide treatment. If designed, built, and maintained correctly, bioretention appears to provide sustained treatment of stormwater runoff for nitrogen and phosphorus for nearly two decades, and likely longer.
