What is the relationship between river depth and width and velocity of flow?
Manning equation if the hydraulic radius decreases then the velocity decreases
What is hydraulic mean radius?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
What is significance of hydraulic radius?
The hydraulic radius is used to characterize flow in open channels like rivers and pipes by measuring the ratio of the cross-sectional area of flow to the wetted perimeter. It helps in quantifying the efficiency of flow conveyance, determining the resistance to flow, and calculating flow velocity. A larger hydraulic radius indicates more efficient flow, while a smaller hydraulic radius indicates higher resistance to flow.
What is hydraulic means?
Hydraulic Mean Radius = Cross sectional area of conduit divided by the inside (wetted) perimeter.
What is Hydraulic Radius measured in?
there isn't a measurment for hydraulic radius as far as i know and if you g on any website about it it doesnt have any measurements at the end of it. Josh (A level geography student) hydraulic radius has a unit as it is the ratio of c/s area to the wetted perimeter i. e. A/P so unit of length............ thanks........jayesh gakare,(M.TECH.

What part of the crankshaft can be rolled with a hydraulic roller to increase crankshaft strength?
The main journal radius, rod journal radius or otherwise both are known as the fillet.
What are the three ways in which a river erodes its valley?
Corrasion, Hydraulic action, Attrition

What are three types of erosion that can affect a river valley?
Three types of erosion that can affect a river valley are hydraulic action, abrasion, and attrition. Hydraulic action refers to the force of moving water eroding the river banks, abrasion is the process of rocks and sediment in the water wearing away the riverbed, and attrition occurs when rocks in the river collide, break down, and become smoother over time.
Do river turn wider when it goes to the downstream?
Yes it does, one of the reasons is erosion. Hydraulic action and corrosion erode the bends of the river making the outside bend wider. :P
What is river hydraulics?
River hydraulics involves flowing water and its impact on the landscape. This includes the hydraulic characteristics of streams and rivers ranging from dam break analysis to sediment movement analysis.
How do you calculate the roughness coefficient of a river?
The roughness coefficient of a river, also known as Manning's roughness coefficient, is typically determined through field measurements or reference tables based on the type of channel bed and vegetation present in the river. It is used in the Manning's equation to estimate the flow velocity in open channels. Collecting data on the slope, cross-sectional area, and flow rate of the river, and then using the Manning's equation, can help determine the roughness coefficient.
