5.1. Perencanaan Bangunan Sadap (Romyn) 5.1.1. Saluransekunder A (Sii) - Bsa1 Kiri

This document summarizes the planning of a drainage system (Romyn) for a secondary channel (SII). It includes calculations of the heights of the Romyn and water levels for four sections of the secondary channel: BSA1 Left, BSA2 Left, BSA1 Right, and BSA2 Right. The given parameters such as discharge and Strickler coefficient are used to calculate the cross-sectional dimensions including height, width, area, and velocity. The height of the Romyn structure and submerged depth are also determined for each section. Diagrams illustrate the cross-sections and water levels.
