Comparison of roof runoff water originated from two types of roof material

, 2012
The present study demonstrates the differences in the quality of roof runoff from bitumen shingle and galvanized iron test roofs. Average first flush conductivity was found to be 113.6 μS/cm in bitumen roof runoff as opposed to 45.4 μS/cm in galvanized ...

A fuzzy TOPSIS-based approach for prioritizing low-impact development methods in high-density residential areas

Water Science and Technology
The study successfully implemented six low-impact development (LID) methods to manage surface runoff in urban areas: green roof, infiltration trench, bio retention cell, rain barrel, green roof combined with infiltration trench, and rain barrel combined ...

Developing a universal tunnel span classification from global tunnel databases

Deep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.

Governing Sponge City Transitions: Policy Objectives and Socio‐Technical Change

Environmental Policy and Governance, EarlyView.
ABSTRACT In theory, climate adaptation policy cycles can be framed as being harmonized and goal‐oriented governance processes. Yet any examination of climate adaptation in cities reveals persistent tensions between this logic and the diverse forces shaping adaptation in practice.

Chemodynamics of Trace Pollutants during Roof and Street Runoff

, 1994
The fate of ionic and non-ionic organic compounds and trace metals during roof and street runoff is sensitive to their distribution between sorption onto roof and street material and suspended solids on one hand and the dissolved phase on the other hand.

Validation of a simple and robust multi-residue gas chromatography-mass spectrometry method for the analysis of polycyclic aromatic hydrocarbons, phthalates and biocides in roofing material leachate and roof runoff

Journal of Chromatography Open, 2021
A multi-residue method for the determination of 16 polycyclic aromatic hydrocarbons (PAHs), biocides diuron (DIU), octylisothiazolinone (OIT) and mecoprop (MCPP), and phthalates bis(2-ethylhexyl) phthalate (DEHP) and diisodecyl phthalate (DIDP) in ...

Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.

Chemical behaviour of trace pollutants during roof and road runoff

, 2009
The fates of ionic and nonionic organic compounds and trace metals during roof and road runoff are sensitive to their distribution between sorption onto roof and road material and suspended sediments on the one hand and dissolution on the other hand ...

Towards a generic rainfall-runoff model for green roofs

Water Science and Technology, 2010
A simple conceptual model for green roof hydrological processes is shown to reproduce monitored data, both during a storm event, and over a longer continuous simulation period. The model comprises a substrate moisture storage component and a transient storage component.
