EVALUASI BEBERAPA METODE PENENTUAN NILAI MODULUS DRAINASE PADA LAHAN SAWAH DI DAERAH DESA SEI BERAS SEKATA KECAMATAN SUNGGAL KABUPATEN DELI SERDANG
ABSTRACT: The aim of this
study was to quantify and to compare the modulus values of wetland ricefield
drainage in the village of Sei Beras
Sekata. Drainage modulus
value is used
as a reference
to throw out
water from the
wetland ricefield. Drainage modulus values was calculated by three methods i.e plotting maximum daily rainfall, daily inundation
simulations with a daily water balance in the mapped fields, and using the
formula of the Department of Public Works. It was found from the research, that
the drainage modulus
values on daily
maximum rainfall plotting
methods was 29
mm day-1, the
daily inundation simulation methods
with high daily
water balance mapped
fields was 40.3
mm day-1, and
formula of the Department of Public Works was 61,2 mm
day-1.
Key words: drainage modulus,
wetland ricefield, Sei Beras Sekata
