Malaysia is a country in Southeast Asia that is constantly exposed to
flooding and landslides. The disaster has caused some troubles such as
loss of property, loss of life and discomfort of people involved. This
problem occurs as a result of climate change leading to increased
stream flow rate as a result of disruption to regional hydrological
cycles. The aim of the study are: to determine hydrologic processes
between the western and eastern coasts of Peninsular Malaysia; to
describe the basin characteristics and their responses to climate
variability and to evaluate the simulation, calibration and
verification of precipitation-runoff model. Based on parameter
precipitation-runoff models, hydrologic processes are parameterized to
account for the spatial and temporal variability of basin
characteristics. For hydrological modeling of the basin, the Soil and
Water Assessment Tool (SWAT) model such as relief, soil type and its
use, and historical daily time series of climate and river flow rates
are studied. The Penman-Monteith (PM) method is commonly used as the
reference for calculating reference evapotranspiration (ETo). The
interpretation of Landsat map/land uses will be applied in this study.
The combination of SWAT and climate models, the system will predict an
increase in future scenario climate precipitation, increase in surface
runoff, increase in recharge and increase in the total water yield.
This disproportionate change can be attributed to more heavy
precipitation events in future climates and the nonlinear nature of
hydrologic budget components, such as evapotranspiration, surface
runoff and groundwater flow. The SWAT model was considered accurate
and qualified for hydrological simulations in this study. It is
observed that the SWAT model will present a statistical approach to
some cases of floods, qualify the model for hydrologic simulation,
identify minimum and maximum flows, calibration and validation flow
for the river basin,and finally act as good estimation for future
flood predictions.

Coastal flood events that have occurred in at least two decades have
begun to be felt by the community that are living near the coast in
present time. Processes running quite slow once but now it has
increased simultaneously with the occurrence of the phenomenon of
global warming. Many settlements in the coastal area have now moved to
a safer area, and no doubt this flood will be more often and heavier
in the future, not only causing harm to the coastal population, but it
is also a national disaster.
