Preliminary Field Evaluation of Soil Compaction in Rain Gardens

Assessing Stormwater Nutrient and Heavy Metal Plant Uptake in an Experimental Bioretention Pond

“…Landscape designers have the opportunity to contribute to the mitigation of the stormwater management problem, by incorporating these solutions in the design of residential gardens, corporate and institutional landscapes, and public green spaces, in order to combine aesthetic quality objectives with functional gains for the development of a more sustainable landscape [21].More recently [22], the term Blue-Green Infrastructure (BGI) has been used to define a planned network of natural and semi-natural areas that utilize natural processes to improve water quality and manage water quantity by restoring the hydrological function of the urban landscape and managing stormwater. In particular, bioretention structures are BGIs that mimic the hydrologic function of a natural landscape providing both flood control and water quality benefits [23].An experimental project was conducted in the Agripolis Campus of the University of Padova (Italy) in order to evaluate the efficiency in runoff reduction and water quality improvement of two bioretention solutions characterized by different scale and slightly different functions.One solution is a rain garden system, already investigated in other environmental conditions (e.g., [24][25][26][27][28][29][30][31][32][33][34][35][36]) but not in Italy, whose research results were recently published [37,38].The other solution is a new proposal, i.e., a bioretention pond (BP) with impervious walls to store and treat stormwater runoff as in floating treatment wetland (FTW) systems [39,40] with living ornamental plants. The BP is intended for green areas within blocks, mall centers, etc., to create a setting with aesthetic features and also able to intercept and retain stormwater runoff, reducing the peak discharge into the drainage system or main stream network, decreasing pollutants in the overflow water, and eventually working as a water reservoir for sustainable supplemental irrigation of beddings or other plant settings during drought periods.…”

Evaluation of Soil Compaction in Building Construction Projects

“…Tidak sedikit dari proyek konstruksi yang melakukan pemadatan menggunakan tanah timbunan untuk menaikan elevasi tanah dasar. Tanah yang digunakan untuk bahan timbunan harus dipadatkan agar dapat meningkatkan daya dukung, mengurangi penurunan (Ardakani & Kordnaeij, 2019) dan infiltrasi (Yergeau & Obropta, 2013). Pemadatan merupakan salah satu teknik perbaikan tanah yang paling efisien dan praktis digunakan pada pekerjaan tanah (Altun et al, 2008;Park, 2010).…”

Integrated planning framework for urban stormwater management: one water approach

“…Due to the lot-level nature of raingardens and downspout disconnections, very few studies have investigated the quantified treatment efficiencies of either of these BMPs. Although there are many studies that have quantified the effects of raingardens, many of the BMPs described in these studies are defined as BR cells under the nomenclature of this thesis (Elliott et al 2011;Guo and Luu 2015;Yergeau and Obropta 2013).…”
