Kereta Tenggelam Sebab Banjir? Jangan Sesekali…

Selepas banjir surut, periksa kereta anda. Sekiranya keseluruhan kereta anda tenggelam termasuk enjin dan bahagian dalam kereta,  

JANGAN SESEKALI CUBA HIDUPKAN ENJIN KERETA.

Tindakan ini biasanya akan dilakukan oleh ejen-ejen bengkel atau kereta penunda. Sebabnya supaya tuan punya kereta terpaksa membayar lebih tinggi untuk membaiki kereta kerana apabila anda cuba menghidupkan enjin kereta, aliran elektrik akan mengalir dan mengakibatkan litar pintas pada kotak komputer.

Ini berlaku kerana masih terdapat saki baki air di dalam alat berkenaan, dan jika ia berlaku, alat tersebut terpaksa diganti. Kos untuk sebuah kotak komputer adalah lebih kurang RM1000 — RM1500 bergantung kepada jenis kereta, cc dan pilihan pengguna.

Tindakan ini juga akan menyebabkan kesemua sensor yang biasanya akan beroperasi semasa kita menghidupkan enjin terbakar. Biasanya satu sensor harganya tidak berapa mahal tetapi kesan daripada sensor yang tidak berfungsi boleh menyebabkan kos yang tinggi.

Kita ambil contoh, sensor untuk mengesan atau untuk mengarah minyak kotak gear (gearbox) mengalir dengan baik di dalam kotak gear apabila tidak berfungsi akan menyebabkan pengagihan minyak gearbox tidak sekata dan paling lama gearbox tersebut boleh berfungsi dengan baik adalah 2 hingga 3 bulan. Selepas itu, keseluruhan gearbox terpaksa diganti (harga untuk gearbox baru wira 1.6 auto adalah lebih kurang RM7000).

Ini adalah salah satu sebab kenapa apabila kita membeli kereta baru, waranty kereta akan termansuh apabila kita mengubahsuai sistem elektirk kereta termasuk sistem audio kereta kerana apabila sensor tidak menerima jumlah elektrik yang cukup, ia tidak dapat berfungsi dengan baik dan peralatan yang berkaitan dengannya akan rosak.


Jadi beringatlah, jangan sesekali berikan kunci kereta anda kepada mekanik ataupun ejen bengkel sehingga dipastikan kotak komputer dan sistem pendawaian elektrik dikeringkan sepenuhnya. Ia tidak akan rosak walaupun ditenggelami air.

Landslide Mitigation—How to Reduce the Effects of Landslides

Vulnerability to landslide hazards is a
function of location, type of human activity,
use, and frequency of landslide events. The
effects of landslides on people and structures
can be lessened by total avoidance of landslide
hazard areas or by restricting, prohibiting,
or imposing conditions on hazard-zone
activity. Local governments can reduce
landslide effects through land-use policies
and regulations. Individuals can reduce their
exposure to hazards by educating themselves
on the past hazard history of a site and by
making inquiries to planning and engineering
departments of local governments. They
can also obtain the professional services
of an engineering geologist, a geotechnical
engineer, or a civil engineer, who can properly
evaluate the hazard potential of a site, built or
unbuilt.
The hazard from landslides can be reduced
by avoiding construction on steep slopes
and existing landslides, or by stabilizing the
slopes. Stability increases when ground water
is prevented from rising in the landslide mass
by (1) covering the landslide with an impermeable
membrane, (2) directing surface water
away from the landslide, (3) draining ground
water away from the landslide, and (4) minimizing
surface irrigation. Slope stability is
also increased when a retaining structure and/
or the weight of a soil/rock berm are placed
at the toe of the landslide or when mass is
removed from the top of the slope.

Landslides and Water

Slope saturation by water is a primary
cause of landslides. This effect can occur
in the form of intense rainfall, snowmelt,
changes in ground-water levels, and waterlevel
changes along coastlines, earth dams,
and the banks of lakes, reservoirs, canals, and
rivers.
Landsliding and flooding are closely allied
because both are related to precipitation,
runoff, and the saturation of ground by water.
In addition, debris flows and mudflows usually
occur in small, steep stream channels and
often are mistaken for floods; in fact, these
two events often occur simultaneously in the
same area.
Landslides can cause flooding by forming
landslide dams that block valleys and stream
channels, allowing large amounts of water
to back up. This causes backwater flooding
and, if the dam fails, subsequent downstream
flooding. Also, solid landslide debris can
“bulk” or add volume and density to otherwise
normal streamflow or cause channel blockages
and diversions creating flood conditions
or localized erosion. Landslides can also cause
overtopping of reservoirs and/or reduced
capacity of reservoirs to store water
