Previous studies reported that the 2015 Gorkha earthquake (Mw 7.8), which occurred in Nepal, triggered landslides in mountainous areas. In Kathmandu, earthquake-induced land subsidence was identified by interpreting local phase changes in interferograms produced from Advanced Land Observing Satellite-2/Phased Array type L-band Synthetic Aperture Radar-2 data. However, the associated ground defo...

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...

Rivers are relief features susceptible to change over time more than any other. Dynamic and intensity of those changes depend on a series of factors that have been a research topic for decades, all with the goal of predicting and/or preventing changes that have a negative effect on ecological and administrative systems alike. This is especially evident on big river systems. The topic of water c...
