"Contractors involved in construction in, or adjacent to, rivers and estuaries are open to a range of construction risks from working in this environment. - Not only the primary risk of flooding, but significant risk also stems from scour, poor ground conditions, site drainage, plant operation, site access and tidal impact. - The construction works themselves may also have an impact on the river including impact on flood water levels, changes to the local river regime, scour or siltation and effects on navigation and environmental impacts such as pollution. - "This Manual assists in identifying and managing risks in works design and construction. - Guidance is offered on risk assessment and management techniques, along with the identification of typical risk issues likely to be encountered in the river and estuary environment. - It is essential reading for clients, project funders, contractors, consulting engineers (both in design and supervision role), insurers and those interested with the risks associated with river and estuary engineering."--BOOK JACKET.
