The SFC station consisted of an upflow anaerobic sludge blanket reactor, an anaerobic upflow bed filter and an aerobic ISF, while the MFC station comprised a septic tank and two ISFs. The mean efficiencies for the removal of total chemical oxygen demand, total suspended solids and total Kjeldahl nitrogen were, respectively, 90, 93 and 75% for the SFC and 87, 91% and 74% for the MFC with ISFs operated at hydraulic loading rates of 380 L.m-2.day-1. The sand filters produced helminth-free effluents that complied with World Health Organization recommendations for water intended for agricultural reuse, although the geometric mean of E. coli counts (104 CFU.100 mL-1) was somewhat high, implying that the treated water was appropriate for irrigation in low-tech agriculture.","PeriodicalId":17594,"journal":{"name":"Journal of Urban and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45776531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is related to predicted and ongoing variation of atmospheric temperature and its association with the dynamical evolution of cities. Changes in the roughness pattern of the surface, wind intensity, soil available humidity and radiative properties compared to the natural surfaces characterize the formation of the Urban Heat Island (UHI). A dynamical downscaling of A2 and B1 SRES’s future scenarios from Intergovernmental Panel on Climate Change were performed for Londrina, a medium-size city of Southern Brazil, using the Weather Research and Forecasting model. The main objective of this study is to investigate the impact of these scenarios on the UHI formation and intensity based on different input data, and its role and influence in the rural area. For this, an evaluation of the model and a comparison with the scenarios were done to mitigate the current trends. The results show a tendency in the current situation in following the pessimistic A2 scenario. Also, a drier rural area for the sustainable projection (B1) is found which implicates in a higher temperature and wind patterns modification for both sites, urban and rural region. Both future projections have a direct influence on the UHI intensity and formation, yielding effects in the agriculture and affecting conditions on human comfort over the region.","PeriodicalId":17594,"journal":{"name":"Journal of Urban and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45496894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasingly, stormwater utilities are being established to fund stormwater management programs. As of 2018, there were an estimated 1,800 to 2,000 stormwater utilities in the U.S., however the establishment of these utilities has varied both temporally and spatially across the country. This research examines the factors at the national, state, and local-levels that give rise to this variation. Overall, research findings indicate that a lack of clear legal authority, presence of stormwater regulations, and political and public opposition all influence the establishment of a stormwater utility, however the influence of these factors is more nuanced than shown by previous research. Moreover, this research identified several factors that influence the setup of utilities that had not been previously identified, including variations in state-level implementation and enforcement of stormwater regulations, general public attitudes, and the robustness of a community’s baseline stormwater management program. These different factors come into play to varying degrees in individual communities and whether a community succeeds or fails in setting up a utility depends on the final balance of these factors.","PeriodicalId":17594,"journal":{"name":"Journal of Urban and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41923278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lack of proper planning and inadequate data regarding solid waste generation and collection compound the solid waste management problem. Given the large number of available waste management options and the inter-relationships among them, identifying SWM strategies that satisfy economic or environmental objectives is a complex task. The paper integrates the effects of transfer station(s) to a mathematical model developed for a municipal Integrated Solid Waste Management (ISWM) system and focusses on the effect of inclusion of transfer stations on the overall efficiency and cost-effectiveness of an ISWM system. The model then serves as decision support tool to evaluate various waste management alternatives and identifies the least cost optimal combination of technologies for the collection, transport, treatment and disposal of waste. The constraints include those linking waste flows and mass balance, processing plants capacity, landfill capacity, transport vehicle capacity and number of trips. The linear programming model integrating different functional elements was solved by LINGO optimisation software and various possible waste management options were considered during analysis.","PeriodicalId":17594,"journal":{"name":"Journal of Urban and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44526716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risk reduction management must consider dynamics involving structural risk elements called indicators. The objective of this paper was to simulate an extreme flood event in the Pirapama river basin, Pernambuco State, Northeastern Brazil, and to analyze some risk components, focusing on the application of damage models in the Brazilian scenario. The hydrological model HEC-HMS (Hydrological Modeling System) was calibrated in order to generate streamflow for ungauged areas. The model was able to identify the highest flood peaks and the statistic criteria were consistent with daily simulation. The parameters calibrated for the HEC-HMS model allowed us to generate results used as input flow in HEC-RAS (River Analysis System). The hydrodynamic model HEC-RAS performed steady flow simulations for the peak flow that occurred in 2010. Remote sensing products with high spatial resolution were used successfully to identify and calculate dwellings surface in the municipality of Cabo de Santo Agostinho. Flood damage estimates were performed through transferred depth-damage curves which is a methodological option verified in the literature. The two main Brazilian studies on this field were selected. The difference between the functions is just over BRL$72 per square meter, and around BRL$85 million for the entire area in the 2010 event (BRL$234.58 and BRL$149.11 million). Those values were adjusted for inflation until 2019. A combination of different methodologies is a way to try to overcome the lack of information, but much remains to be done to validate damage analysis, especially in what concerns to prevention.","PeriodicalId":17594,"journal":{"name":"Journal of Urban and Environmental Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48323507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
