Abstract
CASTRO HEREDIA, Lina Mabel; CARVAJAL ESCOBAR, Yesid and CESPEDES LOPEZ, Guillermo. An Application of the Maintenance Basic-Stream Method to the "Tulua" River Basin - "Cauca" River Sub-Basin Area. Tecnura [online]. 2012, vol.16, n.31, pp.33-44. ISSN 0123-921X.
Mankind has used water in different ways (agriculture, urban consumption, industrial activities, etc), making it an engine of economic development of nations, but ignoring the value of the ecosystems that sustain the aquatic environment. Environmental fows are part of a sustainable water system management focused on maintaining a good ecological status. The purpose of this work was to develop and implement a methodology for determining the environmental fow regime (RQA) in the middle of the river basin Tulua, as a pilot basin in the determination of RQA in Colombia. This information was collected hydrological, hydraulic, water quality and water intake and referrals, we used the HEC RAS model, in this case to simulate the hydraulic behavior of the surface current to later verify the information with a model or information associated with ecological and environmental aspects of the proposed RQA and verify the conditions of habitability, and to assess the RQA with consumptive uses of the basin. The methodology was consistent for the section studied, showing a variable RQA and convenient throughout the year, with living conditions imposed.
