Identification of High Risk Feature Regions for Transmission Towers

Abstract

Torrential rainfall or continuous rainfall for a certain period of time may wash out the foundation of transmission towers and cause tilt or collapse of towers. Special attentions are required for the towers locating at the feature regions such as high risk landslides, mediocre risk landslides, mudslides, dip slopes, and fault zones. The towers locating inside or in the neighborhood of these features regions in Geographic Information System are identified and given different alert limits of precipitation. Accuracy and computational speed are both put into consideration in the design of the proposed approach because vast amount of transmission towers is required to process at a time.
