Peak discharge occurs after peak rainfall due to the time it takes for rainwater to travel over land and through drainage systems to reach rivers and streams. When rain falls, it takes time for the water to runoff and accumulate, which can vary based on factors like soil saturation, land surface conditions, and drainage efficiency. Additionally, some water infiltrates the ground and contributes to groundwater flow, which also takes time to emerge in surface water bodies. Thus, the peak discharge is a delayed response to the peak rainfall event.

The average annual rainfall in Washington, D.C. is around 40 inches.
The main types of rainfall are convective, frontal, orographic, and cyclonic. Convective rainfall occurs when warm air rises and cools, leading to condensation and precipitation. Frontal rainfall happens when two air masses with different temperatures meet, causing the warm air to rise and cool. Orographic rainfall occurs when moist air is forced to rise over a mountain range, cooling and creating precipitation. Cyclonic rainfall results from the convergence of air masses around a low-pressure system, leading to widespread precipitation.

It shows us the time between the peak rainfall and peak discharge. Peak rainfall is the highest rain amount. Peak discharge is the highest the water level reaches in the river.

Peak rainfall refers to the maximum amount of rainfall measured or recorded within a specific period of time, usually within a day or an hour. It is an important metric in understanding the intensity and impact of a particular rain event on an area.
Landslide activity happens when the hillside has become supersaturated from the peak rainfall activity and can no longer absorb any more water. The weight of the hillside, along with not enough anchoring trees or plant life to hold it, causes the slippage of the mud.

Peak discharge occurs after peak rainfall due to the time it takes for rainwater to travel over land and through drainage systems to reach rivers and streams. When rain falls, it takes time for the water to runoff and accumulate, which can vary based on factors like soil saturation, land surface conditions, and drainage efficiency. Additionally, some water infiltrates the ground and contributes to groundwater flow, which also takes time to emerge in surface water bodies. Thus, the peak discharge is a delayed response to the peak rainfall event.
Hamburg, Germany experiences an average monthly rainfall of around 70-80 mm, with peak rainfall occurring in the summer months of June, July, and August. However, it's important to note that rainfall patterns can vary year to year.
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.
To calculate the lag time of a hydrograph, you first identify the peak discharge point on the hydrograph and then locate the corresponding point where the rainfall event begins. The lag time is the time difference between the start of the rainfall and the peak discharge, typically measured in hours. This value helps in understanding the response of a watershed to precipitation events.

during the design of drainage, the rainfall data provides the designer rainfall factor. the area of the site or tributary area is given. the volume of water within the tributary area is equal to rainfall depth and the tributary area also it helps to estimate time of concentration and peak runoff rate it is important to design of drainage
The Rhine River can experience flooding year-round, with peak flooding typically occurring in late winter and early spring due to melting snow and heavy rainfall. Floods can also be triggered by intense rainfall events at any time of the year.
