STRUCTURE OF DAMS
A dam is a hydraulic structure of
fairly impervious material built across a river to create a reservoir on its
upstream side for impounding water for various purposes.
These purposes may be Irrigation, Hydro-power,
Water-supply, Flood Control, Navigation, Fishing and Recreation. Dams may be
built to meet the one of the above purposes or they may be constructed
fulfilling more than one.
Based on the functions of dam, it can be classified as follows:
Storage dams: They are constructed to store water during the rainy season when there
is a large flow in the river. Many small dams impound the spring runoff for
later use in dry summers. Storage dams may also provide a water supply, or
improved habitat for fish and wildlife. They may store water for hydroelectric
power generation, irrigation or for a flood control project. Storage dams are
the most common type of dams and in general the dam means a storage dam unless
qualified otherwise.
Diversion dams: A diversion dam is constructed for the purpose of diverting water of
the river into an off-taking canal (or a conduit). They provide sufficient
pressure for pushing water into ditches, canals, or other conveyance systems.
Such shorter dams are used for irrigation, and for diversion from a stream to a
distant storage reservoir. A diversion dam is usually of low height and has a
small storage reservoir on its upstream. The diversion dam is a sort of storage
weir which also diverts water and has a small storage. Sometimes, the terms
weirs and diversion dams are used synonymously.
Detention dams: Detention dams are constructed for flood control. A detention dam
retards the flow in the river on its downstream during floods by storing some
flood water. Thus the effect of sudden floods is reduced to some extent. The
water retained in the reservoir is later released gradually at a controlled
rate according to the carrying capacity of the channel downstream of the
detention dam. Thus the area downstream of the dam is protected against flood.
Debris dams: A debris dam is constructed to retain debris such as sand, gravel, and
drift wood flowing in the river with water. The water after passing over a
debris dam is relatively clear.
Coffer dams: It is an enclosure constructed around the construction site to exclude
water so that the construction can be done in dry. A cofferdam is thus a temporary dam constructed for facilitating construction. A
coffer dam is usually constructed on the upstream of the main dam to divert
water into a diversion tunnel (or channel) during the construction of the dam.
When the flow in the river during construction of the dam is not much, the site
is usually enclosed by the coffer dam and pumped dry. Sometimes a coffer dam on
the downstream of the dam is also required.
STRUKTUR BENDUNGAN
Bendungan adalah struktur
hidrolik dari bahan yang cukup tahan dibangun di sungai untuk membuat reservoir
di sisi hulu untuk menampung air digunakan berbagai keperluan.
Pembangunan ini bertujuan untuk Irigasi, PLTA, Penampungan Air, Pengendalian Banjir, Navigasi, Perikanan dan Rekreasi. Bendungan dapat
dibangun untuk memenuhi salah satu tujuan di atas atau mereka dapat dibangun
memenuhi lebih dari satu.
Berdasarkan fungsi
bendungan, dapat diklasifikasikan sebagai berikut:
Bendungan Penyimpanan: Mereka dibangun
untuk menyimpan air selama musim hujan ketika ada aliran besar di sungai.
Banyak bendungan kecil mengandangkan limpasan air untuk digunakan di musim
panas yang kering. bendungan penyimpanan juga dapat menyediakan pasokan air,
atau meningkat habitat untuk ikan dan satwa liar. Mereka dapat menyimpan air
untuk pembangkit listrik tenaga air, irigasi atau untuk proyek pengendalian
banjir. bendungan penyimpanan adalah jenis yang paling umum dari bendungan dan
secara umum bendungan berarti bendungan penyimpanan kecuali memenuhi syarat
sebaliknya.
Bendungan Pengalihan: Sebuah bendungan
pengalihan dibangun untuk tujuan mengalihkan air dari sungai ke kanal
off-mengambil (atau saluran a). Mereka memberikan tekanan yang cukup untuk
mendorong air ke selokan, kanal, atau sistem alat angkut lainnya. bendungan
lebih pendek tersebut digunakan untuk irigasi, dan untuk pengalihan dari aliran
ke reservoir penyimpanan yang jauh. Sebuah bendungan pengalihan biasanya tinggi
rendah dan memiliki reservoir penyimpanan kecil di hulu. Pengalihan bendungan
adalah semacam bendung penyimpanan yang juga mengalihkan air dan memiliki
penyimpanan kecil. Kadang-kadang, istilah bendung dan bendungan pengalihan
digunakan secara sinonim.
Bendungan Penahanan: bendungan Penahanan dibangun untuk pengendalian banjir.
Sebuah bendungan penahanan menghambat aliran di sungai di hilir selama banjir
dengan menyimpan air banjir. Jadi efek dari banjir tiba-tiba dikurangi sampai
batas tertentu. Air dipertahankan dalam reservoir kemudian dirilis secara
bertahap pada tingkat yang terkendali sesuai dengan daya dukung saluran hilir
bendungan penahanan. Dengan demikian daerah hilir bendungan dilindungi terhadap
banjir.
Bendungan Puing: Sebuah bendungan puing-puing dibangun untuk
mempertahankan puing-puing seperti pasir, kerikil, dan drift kayu mengalir di
sungai dengan air. Air setelah melewati bendungan puing-puing relatif jelas.
Peti bendungan: Ini adalah kandang dibangun di sekitar lokasi
pembangunan untuk mengecualikan air sehingga pembangunan dapat dilakukan dalam
kering. Sebuah cofferdam demikian bendungan sementara dibangun untuk
memfasilitasi konstruksi. Sebuah bendungan peti biasanya dibangun di hulu
bendungan utama untuk mengalihkan air ke dalam terowongan pengalihan (atau
saluran) selama pembangunan bendungan. Ketika aliran di sungai selama
konstruksi bendungan tidak banyak, situs biasanya tertutup oleh bendungan peti
dan dipompa kering. Kadang-kadang bendungan peti di hilir bendungan juga
diperlukan.
