Manning-type relations do not contain the term viscosity, which limits their use to the field of rough turbulent flow. Strickler roughness coefficient k or n of Manning are estimated with great difficulty, requiring a proven practical experience. In order... see more

Groundwater serves as the most reliable source of water both for domestic use and for irrigation in arid zones, which are characterized by low rainfall and high evaporation. To overcome the water scarcity in these regions traditional w... see more
The article looked at the possibility of making use of a triangular broad crested device, provided with a crest height P and a constant apex angle q, as a flow measurement weir. The device has a triangular gorge which extends over a certain length L. This... see more

Among the hydraulic parameters describing the classical hydraulic jump are the inflow Froude number, the sequence depth ratio, the jump surface profile, and the energy loss.Literature analysis showed that these parameters varied according to the shape of ... see more
An in-depth theoretical and experimental study is carried out on a semi-modular device for measuring flow in open channels, in the current instance a rectangular open-channel of width B. The device is provided with both a crest height P and a lateral cont... see more

In this article are presented the results of studying the operating conditions in the transient mode of an inverted syphon with rectangular pipes, which at the same time experience increased hydrodynamic loads, often leading to one or another destruction.... see more

This paper deals with the mechanism of the uplift of dust from the Sahara in the atmosphere. The first study carried out in 2001 showed that it is at the level of the mega-obstacles of the Sahara that the wind dynamics are very active. So, if there is dus... see more

The assessment of sediment transport in river is important in water resource management such as the design and control dams and other hydraulic structures. In this paper, Three Artificial Neural Network methods are used to estimate the daily suspended sed... see more

Weir is widely used for controlling the flow discharges and water levels of a bifurcated river for flood risk reduction. The effects of weir on the bifurcation flow properties and hydrodynamic processes were not systematically studied by previous research... see more

The present knowledge on the behavior of hydraulic jumps is only for smooth, horizontal channel beds. Very limited studies have been reported in the literature on the performance of hydraulic jumps on rough beds.The objective of our study is to investigat... see more
