5 MODULE ACTIVITIES AND PROCEDURES GENERAL BACKGROUND

◆Construction activities typically are initiated with a clearing and grading activities thus will leads to remove the original vegetation from the site.

◆In Malaysia, particularly in and in the neighbouring urban centers of the valley, urban development was particularly rapid in the late 1970s and 1980s. (DID, 2000) GENERAL BACKGROUND

◆Construction sites in Malaysia usually involve bare eroding slopes and drains chocked with sediment. Highland development has been rapid in the last two decades in Malaysia and has resulted in acute environmental problems in many locations such as Penang, Klang Valley and other strong growth areas. Apart from urban expansion, development has also occurred in inland hilly areas as well as near coastlines and on islands for resort purposes. Planning and achieving sustainable development in such environment is particularly important in such environment is particular important in regard to drainage, flash flood, erosion and sediment and slope stability management.

This module is suitable for undergraduate/ engineers/ local authorities Pathway towards Improved Water Education Curricula MODULE OBJECTIVE

i. Understand the concept and overview on highland drainage, mudflow, debris, sediment erosion and landslide control. ii. Evaluate the method in control sediment erosion and landslide iii. Apply the concepts and mitigation method in order to control sediment, erosion and landslide. LEARNING OUTCOME

i. Understand the concept of highland drainage, mudflow, and debris. ii. Identify the integration of highland drainage, mudflow, and debris with sediment, erosion and landslide. iii.
