Glue-laminated timber, or glulam consists of sawn lumber laminations bonded with adhesive. The grain of all lumbers is aligned parallelly with the lo…
Direct Runoff Hydrograph
Base flow separation allows us to know which part of the hydrograph is contributed by quick-response flow i.e. direct runoff. To do so, we may use th…
Mechanical Properties of Woods
The modulus of elasticity of wood is the highest in the longitudinal direction, and it range usually lies between 1 million and 2 million psi (6.9 an…
