The Impact

West Nile virus (WNV) is the most widely distributed arbovirus in the world and the spread is influenced by complex factors including weather conditions and urban environmental settings like storm water management ponds (SWMP). The purpose of this work was to develop an ordinary differential equation model to explore the impacts of SWMP, temperature and precipitation on WNV vector abundance and the transmission of WNV between mosquito and bird populations. The model was used to analyse how weather conditions and SWMP can influence the basic reproduction number. The results found that an excess of precipitation and fiercer intraspecific competition will reduce vector population and the peak value of infectious vectors and birds. This information can be used to identify measures that would be useful to control larval abundance in SWMP and the transmission of WNV.

The Impact

Since its introduction to North America in 1999, West Nile virus (WNV) has had devastating impacts on native host populations, but to date these impacts have been difficult to measure. Using a continental-scale dataset comprised of a quarter-million birds captured over nearly two decades and a recently developed model of WNV risk, we estimated the impact of this emergent disease on the survival of avian populations. We find that populations were negatively affected by WNV in 23 of the 49 species studied (47%). We distinguished two groups of species: those for which WNV negatively impacted survival only during initial spread of the disease (n = 11), and those that show no signs of recovery since disease introduction (n = 12). Results provide a novel example of the taxonomic breadth and persistent impacts of this wildlife disease on a continental scale. Phylogenetic analyses further identify groups (New World sparrows, finches, and vireos) disproportionally affected by temporary or persistent WNV effects, suggesting an evolutionary dimension of disease risk. Identifying the factors affecting the persistence of a disease across host species is critical to mitigating its effects, particularly in a world marked by rapid anthropogenic change.

Purpose This study aims to assess the impact of adopting selected green construction site practices on the health and safety performance of the construction projects. The impact of storm-water management, energy management and construction waste management on projects health and safety performance was also examined. Design/methodology/approach A survey was conducted to collect information from Class A contractors in Nigeria, and 168 usable responses were received. The data were analysed using the partial least squares (PLSs) structural equation modelling technique. Findings The findings indicate that energy management and waste management practices have significant effects on the health and safety performance of the construction projects, while storm-water management has no effect. Practical implications Project and site managers need to take into consideration the skill set of their workforce when attempting to adopt new innovative construction strategies the workers are unfamiliar with in a changing construction environment. There is also a need for more training of workers on generic and specific green skills to avoid health and safety challenges on site. Originality/value The findings of this study make significant contribution to the debate on the health and safety performance of green projects, as only a few studies have been conducted on this topic. The empirical relationships between the constructs of energy management, waste management, storm-water management and health and safety performance are unique in the context of other related studies and have advanced the body of existing knowledge.

Abstract As communities grows, the area covered by rooftops and concreted surfaces increases. Rain water which would have infiltrated, flows across these impermeable surface carrying pollutants along the way. This causes frequent flash floods in urban areas. Effective storm water management is needed for the sustainable development of communities. In this study the runoff generation for a small catchment is quantified and the effectiveness of low impact development (LID) practices (permeable pavements (pp) & vegetative swales) in mitigating the runoff at the source itself is studied using Storm Water Management Model (SWMM). The most influential design storm and the soil type pertaining to the study area were the determining factors for evaluating the impact of LID’s. The steady flow model and Hortons’s infiltration parameters for the soil type in study area were adopted for the analysis. The permeable pavements and swales performed well in reducing the runoff but the swales were less efficient in reducing the runoff, and the runoff reduction potential of permeable pavements and swales are 4.48% and 2.05% respectively. Runoff reduction is more efficient in case of combination of permeable pavements and vegetative swales as LIDs. The percentage reduction in runoff is about 6.05% and the efficiency of the combination type LID is about 17%. The results from simulation show that the low impact development practices are efficient in mimicking the pre-development hydrologic conditions of the landscape to a great extent.

Abstract Flood modelling is an effective way to manage the stormwater network in cities. It aims to understand and predict the behaviour of stormwater network so that it can test and evaluate effective solutions to structural and operational problems. So simulation modelling stays a preoccupation for building a successful hydraulic modelling in urban areas. This study investigates the impact of the design rainfall on the hydraulic modelling results for the Azzaba stormwater network located in the North-East of Algeria by using the Storm Water Management Model (SWMM). Four scenarios of design rainfall events were compared for 10, 25 and 50-year return periods, where we used double triangle and composite curves for the design rainfall event definition. The results show the impact of the choice of design rainfall on the behaviour of the stormwater network, from which the results of simulation by the double triangle method for the short durations represents a great risk on the probability that the stromwater network can overflow and flood the city, with a difference in peak discharge estimated at 62.97% and 58.94% for 2 h and 3 h events compared to the peak discharge simulated by the composite rainfall method.

Inland Inundation

<p>With the rapid pace of urbanization and drastic transformation of economic form, Wuhan, a central city of China is facing serious inland inundation problems in recent decades. This study intends to alleviate Wuhan’s storm water management problems in a sustainable way and give suggestions as to the improvement of residential area storm water management and lakeside wetland protection. Based on the data provided by Geographical Information System, analysis is done to the land form of the whole city and the change of its lake areas, which evidently demonstrates the influences of economic development on the natural environment of the city and reveals the causes of the inundation problems. Taking the population growth, land use and climate change into consideration, this research argues that strategies such as green roof fostering, neighbor-hood water reuse and wetland conservation can make a difference in stormwater drainage and prevention of inland inundation in Wuhan.</p>
