background: corrosivity is one of the factors affecting the water quality. not controlling the chemical quality of water in the distribution network causes corrosion, sedimentation and economical and health damages. the aim of this study was to determine the drinking water corrosivity and sediment of kuhdasht, iran by using the corrosivity index. methods: in this study, 12 predetermined areas l...
Although a small portion of the Earth's surface is covered by the mountains, but it has a large impact on watershed hydrological perspective Because of the water crisis in arid and semi-arid regions of Iran, monitoring of the amount of snow in these areas is very important. Usually, access to the spatial distribution of snow water equivalent is limited to small scale using sampled data. However...
Abstract Background and objective: Bioindicators of drinking water are always influenced by physical and chemical factors such as turbidity and chlorine. Considering the assessment of drinking water quality is based on residual chlorine, E.coli, heterotrophic bacteria and turbidity. We aimed to evaluate the effect of pH, chlorine residual and turbidity on the microbial ...

extended abstract abstract pressure management is an effective method for water demand management. for evaluation of the effects of pressure changes on leakage level of water networks, the favad equation is usually used. however, in this equation, exponent of pressure parameter (n) needs to be determined. for estimation of n, either some information about the leak opening is necessary or networ...
