Previous studies have shown that the presence of nitrate in drinking water can cause several diseases especially in the infants, such as cancer and blue baby. The Environmental Protection Agency (EPA) has since adopted the 50 mg/l standard as the maximum contaminant level (MCL) for nitrate for regulated public water systems. This study aimed to evaluate the concentration of nitrate in the drink...

This study is the first step to evaluate effectiveness of ENVI-Met simulation models for further research on improvement outdoor thermal condition neighbourhood typologies in city Ha Tinh, Viet Nam. In this research, rural ward Thach Dai that represents a sub-urban typology was case where simulations typical days summer 2020 and on-site measurements model validation were performed. The measurem...

A microclimate classification of the entire Bologna Municipality has been carried out in order to give a tool local administration drafting General Urbanistic Plan (PUG). The city was classified considering variation air temperature as function surface characteristics, vegetation fraction, building density and H/W ratio (height width). Starting from analysis with fluid-dynamic modeling (Envi-me...

In this study, we apply the ENVI-met model to evaluate effects of combinations morphological and vegetation-related landscape features on urban temperatures thermal comfort. We simulated conditions 126 scenarios, varying aspect ratios street canyons, vegetation cover density, surface materials, orientations toward prevalent winds under an extreme heat situation. Our results show how physical pa...
