Based on measured data of velocities of several points along the vertical direction in the center of rotating cylinders using Acoustic Doppler Velocimeter (ADV), we analyzed some turbulent characteristics of flow, such as time-averaged velocity, turbulent intensity, and Reynolds stress. In addition,...

There are abundant geothermal water resources in the deep of Guanzhong Basin, whose origin and renewable ability has been the focus of academic circles .Previous research results of the environmental isotope hydrogeochemistry showed that there was small amount residual sedimentary water formed in the...

This paper provides preliminary analysis on both the morphological characteristics of being wide, curved and branched for braided reach and the influential factors on the channel of the bending braided part. Based on the analysis of a typical river reach as an example, this paper puts forward the channel...

The characteristics of sewage source heat pump and the fouling problem are analyzed in article; four kinds of fouling resistance models, the fouling categories, influencing factors of fouling formation in the heat exchangers, and two kinds of heat exchangers fouling elements were provided. The comparison...

Lots of fast-growing eucalyptuses are planted in Guangxi because of their economic value. Based on the fertility characteristics of fast-growing eucalyptus and Guangxi soil nutrient status planting eucalyptus must pay attention to the application of fertilizer. Therefore, lots of nitrogen and phosphorus...

As the Tropical Rainfall Measuring Mission (TRMM) satellite completes more than a decade of operation, it has provided researchers throughout the world with a large volume of rainfall data. The Yangtze River is the longest river in China, it plays an important role in the regional water cycle, energy...

The scour process is closely related to the damage and failure of pipelines, so the study of the flow field around pipelines and the sediment transport below pipelines is especially important. Furthermore, the effects of scour propagation below submarine pipelines especially around span shoulders have...

Global rainfall data is very important for water resource research. Current rainfall data are mainly from the rain gauge on the ground, ground radar and space borne passive radiometer. This study assesses the successive Version-6 and Version-7 TRMM Multi-satellite Precipitation Analysis (TMPA) products...

The navigation water flow conditions in fluctuating backwater zone of Ankang hydro-junction not only are influenced by daily regulation flow of Shiquan hydro-junction upstream, but also are influenced by reservoir operation of lower Ankang hydro-junction. The flow in fluctuating backwater zone is characterized...

The road along the river in general water scouring, scour, soak for a long time, leading to the highway subgrade, slope and the corresponding protection engineering deformation and collapse, gradually lost its original functions.To water damage roadbed stability analysis and control countermeasure research,...

In the past two decades, the highway mileage of rapid growth, while the rapid development of highway construction, the adverse effects of natural disasters on road transport infrastructure has become increasingly prominent, Loess region has a special terrain , geology and geological climatic conditions,...

the study of the change of water jet in submerged condition is an important foundation of the exploitation of offshore hydrocarbons depending on water jet technology. The characteristics of the flow field structure in different confining pressure conditions are analyzed theoretically and numerically....

The trust level between the owners and contractors is the key factor for project succeed in water conservancy projects. In order to study the level of trust between the owner and the contractor, this paper analysis the indicators of inter-organizational trust level and designs questionnaires according...

In recent years, the promotion of renewable energy has been used in many Qian'an’s buildings, and in which the use of groundwater source heat pump technology is particularly widespread. This work is focused on the comprehensive economic analysis and energy efficiency evaluation of groundwater source...

A practical rainfall generator for meteorological metrology research has been designed. The rainfall generator is adopted to produce a rainfall environment for rainfall instruments test and calibration. The uniformity of the rainfall generator is tested with rainfall collectors and the Christiansen coefficient...

Droplet jetting technology is widely used in 3D printing. In which process, the flow rate of material extrusion from the nozzle is one of the keys that affect the printing performance, such as the droplet size and its uniformity. In this paper, a model was developed to predict the jetting flow rate....
