Investigation Of Water Flow Over Contracted Rectangular Flat-Crested Slit Weir In Open Channel

Empang limpah adalah struktur hidraulik yang tertua dan mudah pembinaannya telah digunakan ke atas saluran terbuka sejak dahulu oleh para jurutera untuk tujuan pengukuran aliran, lesapan tenaga, lencongan aliran, pengaturan kedalaman aliran, saluran banjir dan lain-lain lagi. Terdapat banyak persama...
