📋 Tender Overview
The Regional Government of Lambayeque, through its specialized technical entity Olmos Tinajones Special Project, began the topobathymetry service along 125 linear kilometers of the Huancabamba River channel, as a prior step to the start of dredging of the Limon Dam. This technical intervention responds to what is indicated by the Environmental Assessment and Control Agency (OEFA), with the objective of establishing an updated morphological baseline that allows dredging actions to be carried out with technical support and environmental monitoring.
A team of specialized personnel from the LIDAR Peru firm is in the area carrying out the topobatimetry service (which consists of measuring the channel and aquatic depths of the Huancabamba River) to comprehensively cover the system linked to the Limon Dam, covering a total length of 125 linear kilometers and an approximate area of 10,250 hectares.
The study will allow obtaining precise information on the conditions of the channel, the floodplains and the existing streams in the Huancabamba River, guaranteeing a real and detailed diagnosis of the current conditions of the river before starting the dredging work that will function as a baseline that allows monitoring during and after dredging.
In the downstream sector of the Limon Dam (which extends approximately to the intersection with the Chamaya River), the survey will comprise approximately 110 linear kilometers, with an estimated coverage of 8,350 hectares. In this area, an exhaustive record of the main channel and its banks will be carried out, covering a strip of approximately 300 meters on each side of the river axis, which will allow for a precise analysis of the sedimentation processes and fluvial dynamics in the longest section.
It is necessary to indicate that, within this sector, the first 85 kilometers measured from the Limon Dam have been established as a priority and as a matter of urgency. This survey has been required by the supervisory body OEFA to ensure that the next dredging is carried out under duly supported technical and environmental parameters.
In turn, the upstream sector of the dam will cover approximately 15 kilometers to the Hualapampa ravine, San Felipe district, with an approximate area of 1,900 hectares. In this area, the survey will focus on data capture using LIDAR technology and photogrammetry, innovative tools that will accurately identify the movement of sediments in the Huancabamba River bed.
With this study, the Regional Government of Lambayeque seeks to guarantee a planned, transparent and technically sound intervention, guaranteeing the protection of the environment in one of the main components of the water system of the region and the country.
Once the topobathymetry studies are completed, the Dragatec Consortium will carry out the removal of more than 2 million cubic meters of sediments, a task that will last six months and will allow a greater storage volume to be available at the Limon Dam.
