A mathematical model for the transport of hydrophobic organic contaminants in an aquifer under simplistic riverbank filtration conditions is developed. The model considers a situation where contaminants are present together with dissolved organic matter (DOM) and bacteria. The aquifer is conceptualized as a four-phase system: two mobile colloidal phases, an aqueous phase, and a stationary solid...

Bank filtration of river or lake water represents an efficient and natural purification process used for the drinking water production in many countries and at an amount of about 15-16% in Germany. From experiences over decades particularly at the river Rhine and Elbe, it is known that the occurrence of persistent pollutants in river water can represent a problem for the quality of drinking wat...

Riverbank erosion and lateral channel migration are important geomorphological processes which cause various landscape, socio-economic, environmental consequences. Although those present on the territory of Serbia, there is no available data about soil loss caused by riverbank for entire country. In this study, spatial temporal dynamics largest internal rivers in Serbia (Velika Morava, Zapadna ...

In this chapter, the authors address main issues of Navigation, Guidance, and Control (NGC) and vision system of Autonomous Surface Vessels (ASV). These issues compose research problems and related research findings in recent years. Related research results are reviewed first; then the hardware and subsystem of ASVs is introduced. For the typical rudder-propeller, three degrees of freedom horiz...

The stability of riverbanks in cold regions is affected by the freeze-thaw action. process causes changes moisture content, friction angle, and cohesiveness bank material. Together with effect, seepage pressure influenced changing water levels, slope are key factors affecting stability. A limit equilibrium model considering infiltration effect developed applied to Shisifenzi section Inner Mongo...

In riverbank filtration, contaminant transport is affected by colloidal particles such as dissolved organic matter (DOM) and bacterial particles. In addition, the subsurface heterogeneity influences the behavior of contaminant transport in riverbank filtration. A mathematical model is developed to describe the contaminant transport in dual-porosity media in the presence of DOM and bacteria as m...

Damage to the Pami Riverbank in North Manokwari District, West Papua Province, is generally caused by socio-economic and cultural activities of community DAS (Daerah Aliran Sungai), which a part human intervention against natural systems DAS, such as development-cultivated land watershed. The increasing population growth demand for resources, including water, soil, land, forests, can result cha...
