infiltration rate is one of the most important soil physical parameters and is a basic input data in irrigation and drainage projects. although, a number of theoretical or experimental based equations are presented to describe this phenomenon but the evaluation of some new sciences such as artificial neural networks, for prediction of the phenomenon can be investigated. generally, the infiltrat...

[1] Drainage networks on Titan, Earth, and Mars provide the only known examples of non-volcanic fluvial activity in our solar system. The drainage networks on Titan are apparently the result of a methane-ethane cycle similar to Earth’s water cycle. The scarcity of impact craters and the uneven distribution of fluvial dissection on Titan suggest that the surface may be relatively young. The purp...

Agricultural drainage ditches serve as P transport pathways from fields to surface waters. Little is known about the spatial variation of P at the soil-water interface within ditch networks. We quantified the spatial variation of surficial (0-5 cm) soil P within vegetated agricultural ditches on a farm in Princess Anne, MD with an approximately 30-yr history of poultry litter application. Ditch...

Green cities can solve urban problems without destroying the environment. city planning be implemented through green and design. The purpose of this research is to generate design streets that support realization cities. closely related principles. method used a qualitative with observational data collection. location center Medan City where open space connected city’s main road network. ...

Abstract Redundancy is an important attribute of a resilient urban drainage system. While there lack knowledge on where to increase redundancy and its contribution resilience, this study developed framework for the optimal network structure systems that considers pipeline redundancies. Graph theory adaptive genetic algorithms were used obtain initial layout design The introduction additional wa...
