ABSTRACT

 

Aerial photograph interpretation was used to investigate the activity of the Bournville landslide in South Wales, United Kingdom.  The information from the interpretation is useful for monitoring the movement and remediation of the landslide.  The interpretation on several aerial photographs ranging from year 1946-1991 showed that the major movement had occurred mainly at the southern toe of the landslide. The southern toe of this landslide was regarded as the most critical and crucial part and need to be remediated before further failure could trigger the safety of the landslide.

 

 

ABSTRAK

 

Penafsiran fotograf udara telah digunakan untuk menyiasat aktiviti tanah runtuh Bournville yang berlaku di South Wales, United Kingdom.  Maklumat daripada penafsiran ini adalah penting untuk pemantauan dan pemulihan tanah runtuh ini.  Penafsiran menggunakan beberapa fotograf udara dari tahun 1946-1991 menunjukkan bahawa pergerakan paling banyak berlaku di bahagian selatan tanah runtuh ini.  Bahagian ini dianggap sebagai bahagian paling kritikal dan paling aktif yang perlu diberikan perhatian untuk mengelakkan sebarang kegagalan dari berlaku yang boleh menjejaskan keselamatan awam.
