Evaluación del componente de riesgo hídrico en él era de la cuenca gacheta y las subcuencas blanco-Sumapaz y blanco-calera, pertenecientes a la cuenca del Río Blanco, jurisdicción CAR

Abstract

The internship is developed within the legal framework of the National Policy for the Integral Management of Water Resources (PNGIRH), which establishes the objectives, strategies, goals, indicators and strategic lines of action for the management of the water resource in the country, in a horizon of 12 years. This policy arises from the National Development Plan (PND) 2006-2010 "Community State: Development for All", which in its chapter 5 "Environmental and risk management that promotes sustainable development" incorporated as one of its lines of action, so-called integrated management of water resources (IWRM). In the PND 2006-2010 he proposed that the formulation of the National Water Policy should be the result of coordinated work between the Ministry of Environment, Housing and Territorial Development, the National Planning Department -DNP, the Institute of Hydrology, Meteorology and Studies And the participation of other relevant actors. Within the legal framework, it was established that this policy should address the integral management of the water resource, including both surface waters, as well as underground and marine waters, in order to establish objectives, as well as strategies for the efficient use and use of water , the prevention and control of water pollution, harmonizing the social, economic and environmental aspects that influence this management. Resulting in a document that aims to guide the planning, administration, monitoring and monitoring of the water resource at a national level under a comprehensive management criterion. It is based on the conception that water is a natural good of public use administered by the State through regional autonomous corporations, sustainable development and urban environmental authorities. (Viseministerio de Ambiente, 2010) From the previous normativity our project takes importance in the responsibility of the State to generate the cartography and information necessary to guarantee a sustainable use of the water resources of the territory. This work will be carried out through various institutions, including regional autonomous corporations. As CAR, which defines itself as a government agency that is in charge of pushing forward all the policies related to the environment of the country, 2 manage renewable and non-renewable natural resources, and ensure sustainable development (CAR, 2015). It is worth mentioning: The primary function of CAR is to implement the national policies, plans and programs in environmental matters defined by the law of the National Development Plan and the National Investment Plan or by the Ministry of the Environment as well as those of the order regional level entrusted to it under the law within the scope of its jurisdiction. This gives it an important role in the construction of instruments that allow adequate use of the water resource, through the methodologies provided by IDEAM as the document "conceptual and methodological guidelines for the regional assessment of water" (ERA) and the national water study (ENA). These will be the conceptual bases for the accomplishment of the present internship, which intends to evaluate the current state, the trends of the natural water system of the basins of the Gacheta River and the Blanco River Sumapaz and Río Blanco Calera, seeking to establish the incidence of events torrential floods and floods that may affect their social, economic and environmental dynamics.
