In irrigation scheduling, one question is “how much is the optimal depth?”. In this study the optimal irrigation depth (by assuming the power distribution function and by taking into consideration the distribution function, which governs the data (normal distribution)) by considering the environmental effects was determined for three water management strategies (i. e. unlimited, limited nitroge...
Minimizing water supply costs has always been the goal of companies. However, it is not an easy task to minimize and meet customers’ pressure needs in a system with multiple sources different unit discharge. In this paper, we develop search method that incorporates concepts local steepest descent. First, establish discharge each source as variable start searching neighborhood for feasible initi...
Intermittent water supplies (IWS) are routinely experienced by drinking distribution systems around the world, either due to ongoing operational practices or one off interruptions. During IWS events changing conditions may impact endemic biofilms leading hydraulic mobilisation of organic and inorganic materials attached pipes walls with a resulting degradation in quality. To study on microbiolo...
in our previous work, the effect of use of a water soluble cdi/nhs system as nontoxic cross-linking agent on fabrication of gelatin nanoparticles was investigated. in this research, the effect of variation in some synthetic parameters of gelatin nanoparticles cross-linked by cdi/nhs system such as type of gelatin and formulation of cross- linking agent on their size and distribution was examine...
according to the low efficiency of irrigation and drainage networks and water distribution in iran, simulating water flow and sensitivity structures and networks is considered as a new approach to evaluate the performance hydroelectric projects in the country. in this study, because of reduced water supply and distribution, especially in downstream irrigation and drainage networks varamin to ev...
