The shape of a hydrograph

the shape of a hydrograph The shape of a hydrograph varies in each river basin and each individual storm event the hydrographs below show two contrasting environments before urbanisation.

Hydrograph – a graph that shows river discharge and rainfall over time flood – when the capacity of a river to transport water is exceeded and water flows over its banks base flow – the base flow of the river represents the normal day to day discharge of the river and is the consequence of groundwater seeping into the river channel. The shape of the hydrograph varies according to a number of controlling factors in the drainage basin but it will generally include the following features the baseflow of the river represents the normal day to day discharge of the river and is the consequence of groundwater seeping into the river channel.

The shape of a hydrograph is altered by a few different things one factor is the shape of the drainage basin drainage basins come in a wide assortment of shapes. Shape of a hydrograph certain conditions can cause the line on the hydrograph to be tall and thin and other conditions can cause it to be short and wide peak discharge is the term used to describe the maximum amount of discharge from the river over the period of time recorded this peak discharge can be high or low depending on a lot of conditions.

The shape of a hydrograph of a single storm occurring over the drainage area follows a general pattern this pattern shows a period of rise that culminates in a peak, followed by a period of decreasing discharge (called recession) which may, or may not, decrease to zero discharge, depending on the amount of groundwater flow. 484 = scs shape factor (0208 metric) a = area (sq miles) q = total excess precipitation, 1 inch (1 mm) tp = time to peak (hrs) the shape factor is a user-definable variable the default value is set to 484 and creates a unit hydrograph that has 3/8 of its area under its rising limb.

The shape of the hydrograph varies according to a number of controlling factors in the drainage basin a number of factors (known as drainage basin controls) influence the way in which a river responds to precipitation and have an effect on the shape of the hydrograph.

A hydrograph is a graph showing the rate of flow versus time past a specific point in a river, channel, or conduit carrying flow the rate of flow is typically expressed in cubic meters or cubic feet per second (cms or cfs.
