SMDMP will combine hydropower and irrigation benefits and has been declared a National Pride project by the Nepalese government. SMEC will lead a joint venture with EMAY, Jade Consult and CMS Nepal.
This multi-purpose project comprises a conventional concrete diversion weir structure (barrage and under sluice bay) across the Sunkoshi River. A discharge of 67 cumecs will be diverted through an intake structure. The diverted water will be passed through a desander to remove silt, before being conveyed via a 13.1 km concrete lined headrace tunnel to a new surface powerhouse on the Marin River.
The available head between the intake and powerhouse will be utilised to generate 28.62 MW. The water downstream of the tailrace will flow through the Marin and Bagmati rivers and will facilitate a year-round irrigation for approximately 122,000 hectares of irrigable land around Bagmati, helping to increase agricultural productivity whilst contributing to the growing energy needs of the country.
Geo-politically, this project will help keep balance in the use of water resources among the provinces. Eventually the project will help recharge ground water storage and augment base flow in local streams, resulting positive effects in the environment.
Summary of scope:
The Tbilisi Development Fund has engaged SMEC to develop the Dighomi floodplain rehabilitation strategy. The Dighomi Floodplain is an area of special conservation interest, which includes riparian forest, protected Otter habitat and other unique flora and fauna ecosystems that have been assessed as critical by the International Finance Corporate Performance Standard.
SMEC has been contracted by Electricidade De Timor-Leste (EDTL) for the role of Project Supervision Consultants for the Power Distribution Modernisation Project in Timor-Leste. Supported by a loan from the Asian Development Bank (ADB), the project aims to assist EDTL in modernising the country’s power distribution system and strengthening institutional capacity.
Geotechnics will play a key role in helping our society achieve a safe, prosperous and sustainable future. Recent droughts have resulted in a need for more dam design and construction. Recent rainfall has resulted in extensive slop failures impacting our roads, rail and urban infrastructure. Energy transformation is driving large scale solar, wind and pumped hydro construction. These projects will all require geotechnical input to future plan for our communities.
