“…In most cases, the goal of current technical applications of advanced oxidation processes is the destruction of pollutants in water, rather than the energy-intensive complete degradation of the content in the substrate. The most important economic parameter is thus the efficiency of substrate consumption [21][22][23][24][25][26][27].…”

Abstract. The work detailed in this study investigated the efficiency of oxidizing technologie for the removal of organochlorine pesticides (OCPs) from aqueous solutions. OCPs constitute an important group of environmental pollutants also known to be endocrine-disrupting compounds (EDCs). The particular focus has been on a process achieving oxidation through the use of ultrasonic waves, with the impacts of pH, time on TOC and pesticide removal all being tested. Results confirm effective TOC decomposition using ultrasonic waves, albeit with reaction time showing a significant impact on results. Furthermore, results for TOC were not found to reflect those relating to the removal of individual substances from the tested mixture. Chromatographic analysis of reaction mixtures was therefore carried out after the selected processes had been applied, and an attempt to identify and characterize degradation products of the pesticides tested was also made. During the irradiation, the H 2 O 2 concentration arising was also monitored. The results indicate that H 2 O 2 is produced by cavitation during ultrasonic irradiation.

“…Equally important are the factors associated with the selection of rain models, which are suitable for calculating the design parameters of this type of objects. It should be noted that there is a substantial difference in the precipitation of rains accepted for dimensioning sewer pipes of standard drainage networks from networks equipped with retention canals [20][21].…”

“…However, increased surface runoff, faster runoff concentration, and higher peak flow rates can exceed an urban system's drainage capacity and cause inundation, resulting in traffic interruption, economic loss, pollution, and health issues (Dash et al, 2016). Improving the drainage capacity in rapidly urbanizing areas is a straightforward method for reducing inundation risk, and a significant improvement can be achieved in most cases (Pochwa et al, 2017). However, simple and isolated improvements to drainage capacity are now proven to be unsustainable, costly, and even impractical because of great uncertainties in the broader context of land- scape and climate change, particularly in densely urbanized areas.…”

“…Liu et al (2014) assessed the effectiveness of green infrastructure on urban flooding reduction at a community scale and showed that total runoff reduction ranged from 85-100 % and peak flow was reduced 92.8-100 %. Pyke et al (2011) illustrated the potential benefits of a common LID practice for increasing the resilience of communities to changing precipitation patterns. This objective of this study was to determine whether SCMs can reduce the inundation risks in urban drainage systems and assess the reduction under different rainfall conditions using scenario analysis.…”

Abstract. Urban inundation is a serious challenge that increasingly confronts the residents of many cities, as well as policymakers, in the context of rapid urbanization and climate change worldwide. In recent years, source control measures (SCMs) such as green roofs, permeable pavements, rain gardens, and vegetative swales have been implemented to address flood inundation in urban settings, and proven to be cost-effective and sustainable. In order to investigate the ability of SCMs on reducing inundation in a community-scale urban drainage system, a dynamic rainfall-runoff model of a community-scale urban drainage system was developed based on SWMM. SCMs implementing scenarios were modelled under six design rainstorm events with return period ranging from 2 to 100 years, and inundation risks of the drainage system were evaluated before and after the proposed implementation of SCMs, with a risk-evaluation method based on SWMM and analytic hierarchy process (AHP). Results show that, SCMs implementation resulting in significantly reduction of hydrological indexes that related to inundation risks, range of reduction rates of average flow, peak flow, and total flooded volume of the drainage system were 28.1-72.1, 19.0-69.2, and 33.9-56.0 %, respectively, under six rainfall events with return periods ranging from 2 to 100 years. Corresponding, the inundation risks of the drainage system were significantly reduced after SCMs implementation, the risk values falling below 0.2 when the rainfall return period was less than 10 years. Simulation results confirm the effectiveness of SCMs on mitigating inundation, and quantified the potential of SCMs on reducing inundation risks in the urban drainage system, which provided scientific references for implementing SCMs for inundation control of the study area.
