WebStream Hydrology. Streams are created when excess water from rain, snowmelt, or near-surface groundwater accumulates on the ground surface and begins to run downhill. This excess water from rain or snowmelt generally occurs when the water accumulates at a faster rate than the soil and organic matter (e.g., dead and decaying vegetation) can ... WebIn hydrology, discharge is the volumetric flow rate (in m 3 /h or ft 3 /h) of water transported through a given cross-sectional area. It includes any suspended solids (e.g. sediment), …

WebAug 2, 2014 · The average flow velocity of a river increases along its long profile. This makes sense; along the profile, more potential energy is converted to kinetic energy, increasing the velocity. This is only the average velocity however; a cross-section of a river shows that the velocity varies from one side to the other. WebExamples of simple flow patterns are shown in Figure 1.48 with the equations to their stream functions and velocity potentials. A source is mathematically a point at which fluid appears and flows radially outwards. A sink is a negative source at which fluid flows radially inwards to disappear at a point (similar to the plug hole in a domestic sink, where, …
