Model Persamaan Liku Kalibrasi Menggunakan Pendekatan Regresi Untuk Mendukung Analisis Keterrsediaan Air Perikanan Pada Bendung Batang Samo Kabupaten Rokan Hulu
Decreasing of water debit for agricultural irrigation service is the basic problem in Batang Samo Weir in Rokan Hulu Regency that caused by direct water use for fish ponds at some place around 30,05% along main irrigation channel. To reduce water losses in the primary canal, water flow analysis needed in order to create a new intake channel for the development of fishery area downstream of Batang Samo River.
To support the analysis of water availability for the development of fishery areas, it is necessary to make calibration at Batang Samo Weir from year 2015 until 2016 by using regression analysis approach and determine the dependable flow for the development of fishery areas. The steps of the calibration model (Rating Curve) are the model calibration, verification, simulation, and implementation.
The results of this research obtained the value of the parameters a=21,675 and b=1,5, so that the calibration equation is obtained Q = 21,675 ????????1,5 with the correlation factor, R=1,00 and for the dependable flow discharge obtained Qa=0,115 m3/s or with water volume around 298.080 m3.
