Environmental studies in streams north of Bogota.

Streams/ Aguas Calientes / San Juan / Patiño / Connectivity

Terrestrial fauna, fragmentation and connectivity of Aguas calientes, San Juan and Patiño streams. Hidromecánicas . Contract HMC-150-153-COPS 011

Hydroecological and ecohydraulic report of Aguas calientes, San Juan and Patiño streams. Hidromecánicas. Contract HMC-150-153-COPS 019

As part of the studies and designs for the delimitation of the water course and reconformation and restoration works of the Aguas Calientes, San Juan and Patiño streams, within the scope of the project Ciudad Lagos de Torca, north of Bogota, field studies and numerical analysis were carried out for the characterization of terrestrial fauna (insects, amphibians, reptiles, birds and mammals) in the streams. The ecohydrological report was prepared for the restoration designs, considering ecohydrological criteria and the results of the water quality modeling of the streams. The study of fragmentation and connectivity model of the streams was elaborated through a multitemporal analysis of the vegetation covers (1960, 1984, 2017) considering the ecosystems of the eastern hills of Bogota.

Environmental studies in Torca - Guaymaral wetland.

Wetland/ Torca - Guaymaral / Fauna / Epiphytes / Connectivity

Terrestrial fauna, epiphytes, fragmentation and connectivity of the Torca - Guaymaral wetland. Contract HMC-155-COPS 011

Vegetation cover maps for fragmentation study and connectivity model of the Torca - Guaymaral wetland. Hidromecánicas. Contract HMC-150-153-COPS 015

As part of the development of detailed designs for the construction of the hydrogeomorphological reconformation and ecological recovery works of the Torca - Guaymaral wetland, within the scope of the project Ciudad Lagos de Torca, north of Bogota, field studies and numerical analysis were conducted for the characterization of terrestrial fauna (amphibians, reptiles, birds and mammals) and vascular and non-vascular epiphytic flora of the wetland. Vegetation cover maps (1960, 1982, 2017) were prepared for the fragmentation study and connectivity model of the Torca - Guaymaral wetland in an area of 6457 ha that includes, from east to west, the eastern hills to the Bogotá River and, from south to north, from the northern boundary of the largest urbanization of the urban area of Bogotá to the Bogotá River.

Study of Greenhouse Gases (GHG) in the wetlands of the El Coco lagoon in Puerto Salgar.

El Coco / Puerto Salgar / Greenhouse gas

Study of the wetlands of the El Coco lagoon with respect to the sink functions and sources of Greenhouse Gas (GHG) emissions. Concessionaire Ruta del Sol. Contract No. 073-2014. 3

Measurements were made to estimate GHG emission fluxes in terrestrial and aquatic ecosystems. The main biogeochemical fluxes occurring in the wetland complex associated with CO2, CH4 and N2O were identified and carbon content and production rates in sediments and aquatic macrophytes were estimated.

Preliminary evaluation of alternatives for drinking water supply to Santa Marta.

Alternatives / Santa Marta / Impacts

Preliminary study and analysis of the environmental and social impacts of the Aguas Santa Marta Project. Interaseo S.A E.S.P. Service Order No. 061-OCS-0936.

As part of the evaluation of the potential of two alternative polygons for the implementation of a drinking water supply system for the city of Santa Marta, in the department of Magdalena - Colombia, a basic identification and comparison of environmental restrictions in two areas of the Colombian Caribbean coast was carried out, in order to identify early on the existing environmental restrictions for the areas of interest.

Environmental impact study for material sources. Villavicencio - Yopal road

EIA | Biótic | Road Corridor |

Study of the biotic component of the Environmental Impact Assessment (EIA) for the sources of dragging and quarry material associated with Functional Units 1 to 4 of the Villavicencio- Yopal Road Concession project. Tecniestrategia. Contract TECN-010-2016..
