Why the peak landslide activity occurs later than the peak rainfall activity?
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.
Why is there a lag time between the peak rainfall and peak discharge on a hydrograph?
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.
What does rainfall variability mean?
Rainfall variability refers to the natural fluctuations in the amount and distribution of rainfall over time and space. It can include variations in precipitation intensity, frequency, and duration. Understanding rainfall variability is important for managing water resources, agriculture, and predicting climate change impacts.
When does it floods Rhine?
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.
What does marginal rainfall mean?
Marginal rainfall refers to low or minimal amounts of rainfall that might not be enough to significantly impact water resources or ecosystems. It can indicate below-average precipitation levels in a region, leading to potential drought conditions and water scarcity.
What is Rainfall Peak?
The peak rainfall is the highest amount of rain in a place on a hydrograph.
What does the lag time showon a hydrograph?
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.
When was the peak rainfall?
500 years ago
Why the peak landslide activity occurs later than the peak rainfall activity?
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.
How do you work out lag time on a hydrograph?
the time between the heaviest rainfall and the peak discharge
why the peak discharge occurs after the peak rainfall?
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.
What is a little rainfall mean?
when its not a lot of rainfall
What does peak mean in math?
the peak
What is Germany rainfall monthly hamburg?
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.
What is the mean rainfall?
The meanin Relief rainfall is rain that affects the weather
Why is there a lag time between the peak rainfall and peak discharge on a hydrograph?
