In this course, we go through the development and validation of precipitation rainfall threshold step-by-step.
Using Excel for ID, IE and Antecedent thresholds for early-warning systems, landslides & geo-hydrological risk analysis
What you’ll learn
Employed within early-warning systems for geo-hydrological risk mitigation and Civil Protection purposes
Forecasting Landslides Induced by Rainfall
To understand the theory and the logic of threshold analysis
To easily construct the most significant thresholds in the acad literature
To learn how effectively use, analyze, and visualize the rainfall record
My continuous support, taking your hand step-by-step to make perfect use of the course objectives
Full access (able) to Excel sheet equations and data used in the course
Requirements
No statistical background needed
Basics of Microsoft excel
Basics of QGIS software (optional) for visualization purposes only
Description
You will learn how to effectively build, apply and validate the most powerful Precipitation thresholds, and much more: [Excel sheet and Articles are available for the exercise application purposes]
What is all about with experience sharing : focus on that thresholds that Induces Landslides
How to prepare the data for threshold analysis
Errors and Uncertainties
Correlation between station records
Spatial pattern analysis for incidents and stations
a. Compute the Distance Matrix [distance matrix, rename the source stations as text and target as ID]
b. Compute Nearest Neighbor Analysis [shared nearest neighbor clustering, high no.= less groups]
c. Select points by delete unwanted and outliers
6. Correlation analysis
7. Precipitation Threshold Analysis that Induces Landslides types
a. ID, IE,
b. E-Date, I-Date,
c. Antecedents and others
8.Reliability index
9.Processing steps : first comes first
10.Temporal analysis
Tools: Microsoft excel and open source GIS software QGIS.
