Resumen:
 The Pilcomayo River is astrategic watercourse for northern Argentina, particularly the provinces ofSalta and Formosa. Most of its active basin is located in Bolivia, and furthersoutheast the river becomes the limit between Argentina and Paraguay up to theregion of ?La Embocadura?,where the water is artificially distributed between both countries, and thenflows downstream to natural courses like ?Bañado la Estrella? and ?Río MonteLindo?. The gauge station inVillamontes (VM) give us flow values entering Argentina/Paraguay, and the onein Misión la Paz(MLP) offer us the flow into the distribution system between Argentina andParaguay.The major hydraulicproblems encountered in the basin are the need to calibrate the H-Q curves andthe high variability of MLP section that demands gauging and H-Q curves foreach event. The reach has many overflows, which make the measurement of theflows into Argentina and Paraguay a difficult task. This is a concerning bilateralproblem expressed in many agreements in order to achieve a fair distribution ofthis resource. Flow exceedance analyses wascarried out, together with previous studies using satellite imagery, these twomethodologies are used to look into the flows activating the overflow ElChañaral. Moreover, One-Dimensional hydraulic flood routing of the reach ismodelled including the overflows with accurate estimates in relation to thegauged values, representing the flood of January February 2013.The different methodologies employed allowed us to obtain the flow,measured in Villamontes, which activates the overflow El Chañaral, which forthe period of study was determined to be 2700 m3/s.
