With the development of society and economy, land subsidence in soft soil areas has become a prominent geological disaster our country’s coastal area. Land characteristics irreversibility, wide influence range, long aging, etc., these are closely related to soil, such as physical mechanical parameters, microstructure characteristics, etc. The Nansha District Guangzhou was taken study area this ...

At present, major works on the main rivers of Central Asia (Amudarya, Zerafshan, Chirchik, and others) have been carried out are working to protect banks from erosion regulate channels for guaranteed water intake into irrigation in areas great length. For this widely used transverse dam (spur). During interaction (spur) with flow, there is intensive siltation inter-amber space. Due limited agri...

Abstract The present study focused on the siltation process at navigation channel in Port of Niigata, Japan. A part port is located mouth Shinano River, which longest one country. Due to discharged sediments through river and their deposition area, frequent dredging works are required for safety navigations waterway turning basins. purpose get a better understanding specific features sedimentar...

Studies of plant phenology have been performed predominantly with terrestrial species and rarely so aquatic communities. Such plants are fundamental for the ecosystems, representing a valuable source resources when they scarce in environments fauna. help to understand reproduction rhythms communities provide support management conservation. This study aimed describe reproductive 15 determine ho...

The use of the segmental pipe section immersed tunnel suffers from several problems, such as complex construction, weak foundation, great water depth, thickness siltation back on top tube, and difficult settlement control. Based Winkel’s elastic foundation beam theory, a mechanical calculation model is established according to case an inhomogeneous soil layer, force deformation structural syste...

Hard river engineering or channelization alters channel bathymetry and morphology invites multiple fluvio-hydrological hazards. The linear (72 m), concrete, low height (1.6 multipillars (20 pillars) bridge with concrete embankments revetments has been constructed across along the Bala within Himalayan foothill zone in year 2017. As a result, rate of siltation tremendously increased at vicinity ...

From a sustainable development perspective, becoming aware of the preservation green spaces and creation infrastructure is great challenge for Algerian arid city, especially in environment. Green multifunctional open space networks aimed at resource management environmental improvement. We chose city Bou-saada as case study to demonstrate need infrastructure. This with semi-arid climate, presen...
