Modelo de balance hídrico superficial de un sistema lagunar, caso “laguna negra”, provincia del Chubut

Abstract

In many problems of land use planning, hydrological risk assessment, or intervention with hydraulic works in
the urban development of Patagonia, depressions and chain of lagoons are present, they are morphological
characteristic of the plateau landscape, or the rivers valley and the contact zone. The lack of hydrometric data
for the study of cases is usually a common difficulty, particularly by the temporary watercourses and lagoons.
A hydrological model was designed for calculation the surface-water mass balance in the lagoon system,
studying with focus in this type of landscape and problems. The study permitted a simplified methodology
for the assessment and hydrological analysis of these cases.
Among other uses regional, the model was developed as an analytical tool in the management plan of the
wastewater treatment system in the Trelew city, in the province of Chubut, Argentina. The wastewater of
Trelew are discharged into the existing lagoons between the city and Rawson city. Summarizes the main
findings and conclusions of hydrologic simulation.
