Hydro and Water Management Capabilities

RILEY has significant experience in all areas of hydrological and hydraulic engineering including flood studies; hydrological routing; river and floodplain modelling; spillway capacity and dam break studies for hydro-electric schemes; and resource consent applications and reviews.

We have particular expertise in the hydrological issues and effects associated with the consenting of new and existing hydro-electric schemes.  These large multi-disciplinary projects require a broad range of hydrological and hydraulic field and modelling skills to enable assessment of a broad range of issues associated with engineering, ecological, landscape and planning disciplines.

In order to achieve fast and effective solutions, staff are trained in the use of a number of hydrological and hydraulic modelling packages including:

• Hilltop Software - assessment of existing and post-scheme hydrological characteristics of a river.
• MIKE 11 - dam break, river and floodplain modelling to assess hydraulic effects.
• MOUSE HD - pipe network modelling.
• Hec-Ras - dam break, floodplain and spillway capacity modelling.
• Hec-HMS - rainfall runoff and flood routing to assess catchment behaviour during design floods, including the PMF.
