Landslides Warning System

Landslides Warning System

INTRODUCTION

Landslides are the down slope movement of mass of land, rock, soil, or

related debris. In most mass movement, water plays a pivotal role by

assisting in the decomposition and loosening of rock, lubricating rock

and soil surfaces to enhance the beginning of movement, adding weight

to an incipient landslide, and imparting a buoyancy to the individual

particles, which helps overcome the inertia to move.

Landslides can also be triggered from volcanic eruptions and

earthquakes, which initiate earth movement on a grand scale.

Landslides are frequently the direct consequence of human activity.

They are predominant in highland areas where Agricultural irrigation

and forestry practices such as clear-cutting and stripping vegetation

from naturally oversteepened slopes are eminent. Highway construction

on similar slope conditions awaits only the first good rain to provoke

earth movement. In an urban setting, improper drainage most often

induces disastrous sliding.

The goal of early warning is born from a hope to head off conflict

before it becomes costly. Landslides cause significant economic damage

and hazard to environment all over the world. Apart from preventive

measures, early warning and fast extinction of Landslides are the only

chance to avoid major casualties and damage to nature, especially in

regions with dense population.

ABSTRACT

Landslides are often recurring phenomena, the systems which meant to

deal with the same must meet the domain requirements, be effectively

developed and flexible to changes. What is needed to make these new

warning sensors available is money fo...

ARCHITECTURAL DESIGN

SUBYSTEMS AND THEIR COMPENENTS

Sensors: detects the movement of rocks below the surface through the

gauge wires.

Computation components: receives signals from sensors, determine the

risk and produce some output. The system uses computers.

Communication systems: allow system components to communicate. Optical

fibers are

Used in this case.

Siren: emits an audible warning when a threshold is reached.

Alarm controller: Controls the operation of the system.

External control center: receive commands from the control center and

connects to radio stations and personal landscape warning beeper

systems.
