amount of precipitation
The unit of hydrograph for an infinitesimally small duration of effective rainfall is called unit hydrograph. It represents the response of a watershed to a unit input of effective rainfall over time.
Originally, a storm surge of 9-12 feet was listed for a category 3 hurricane. This association is no longer used as storm surge is influenced by more than just the sustained wind speed used to determine a hurricane's category.
Mechanical weathering, also known as physical weathering, only affects the size and shape of the rock without changing its mineral composition. This can be caused by processes such as freeze-thaw cycles, root wedging, and salt crystal growth.
The lag time between peak rainfall and peak discharge on a hydrograph occurs because it takes time for water to travel through the watershed from where it falls as rain to the main channel of a river. Factors like soil type, topography, land use, and drainage patterns influence the flow pathways and the time it takes for water to reach the stream channel.
A normal storm is a generic term that can refer to any kind of storm, while a thunderstorm specifically includes lightning and thunder due to the presence of cumulonimbus clouds. Thunderstorms are a type of storm that can produce strong winds, heavy rain, lightning, and sometimes hail.
how do you compare and contrast hydrographs
Total Volume of rainfall for that storm event
A storm hydrograph is useful because it shows how a watershed responds to a storm event by plotting discharge over time. This helps in predicting peak flows, assessing flood risk, and designing infrastructure to manage stormwater effectively. It also provides valuable information for watershed management and water resource planning.
The unit of hydrograph for an infinitesimally small duration of effective rainfall is called unit hydrograph. It represents the response of a watershed to a unit input of effective rainfall over time.
A hydrograph is showing the discharge (rate of flow) versus the time past in a specific river point. One of the types of hydrography is called a flood hydrograph, it is used to measure the river's characteristic basically a dual plot of discharge and rainfalls.
Firstly an attenuation is the reduction in the peak of a hydro-graph as it movesdownstream, resulting in a more broad, flat hydro-graph.Therefore the attenuated peak is the highest point before it attenuates.
