A temporary ice resistant boom for the control of the water flow in rivers or lakes

Abstract From the Canadian patent

A permanent structure with temporary use to generate a headloss in a river "HLG Boom" was, developed to provide a means to control the level the velocity or the , discharge of the water in the river at a specific site. The potential applications for the "HLG Boom" is to modify the, amount of water discharged into the out flowing rivers from a lake (Figure 1a), to increase or, decrease the amount of water diverted from a river into a tributary or a canal (Figure 1b), or to, increase the water level in a river thus reducing the current velocity , (Figure 1c). The "HLG Boom" is designed using several self contained boom units connected together with, chains to resist the water and …
