Abstract Ice dams are among the important risks affecting operational safety and water conveyance efficiency of diversion projects in northern China. However, no evaluation indicator system for ice dam risk assessment has been proposed. Therefore, this paper, based on formation mechanism dams, possibility calculation model were both proposed fuzzy fault tree analysis method. The constructed stu...

Gas disaster prevention and control is essential to coal mine safety production, with accurate measurement of gas pressure content being the challenging key aspect. Pressure- gas-maintaining coring devices can characterize cores in situ achieve this measurement. As an important part these devices, hydraulic structure bit plays a decisive role migration, rate, core disturbance bottom-hole cuttin...

This research was prepared as a preliminary laboratory study to achieve moving hydraulic jump with controlled discharges. It is an initial part of the that being treat salt tide occurring in Shatt al-Arab due lack water imports were coming from Karun and Karkheh rivers Iranian territory, this scarcity caused affected significantly environmental reality city Basra agricultural lands surrounding ...

In a previous study, we presented the dimer structure of DNA gyrase B' domain (GyrB C-terminal domain) from Mycobacterium tuberculosis and proposed a 'sluice-like' model for T-segment transport. However, the role of the dimer structure is still not well understood. Cross-linking and analytical ultracentrifugation experiments showed that the dimer structure exists both in the B' protein and in t...

To cope with the water pollution problem, Dongsam seawater stream was newly renovated in 2022. For this maintenance, government constructed various facilities including electric swing sluice gates at both ends to enhance exchange performance. In regard, study tries quantify velocity increment and quality of offer suggestions for effective management. achieve goal, authors performed literature r...

Climate change and human interventions (e.g., massive barrages, dams, sand mining, sluice gates) in the Ganga–Padma River (India Bangladesh) have escalated recent decades, disrupting natural flow regime habitat. This study employed innovative trend analysis (ITA), range of variability approach (RVA), continuous wavelet (CWA) to quantify past future hydrological river because building Farakka Ba...
