    Durante la expedición Cerro Blanco 2017, el INGEMMET, junto con el IRD realizó el monitoreo de las resurgencias y ríos del macizo del Alto Mayo. Se realizó un monitoreo físico-químico e hidråulico, para el cual se utilizaron varios métodos de aforo, como correntómetro electromagnético, ADCP y radar, para estimar el caudal de estas fuentes de agua. Los resultados muestran que, para la fecha de la expedición, los ríos y resurgencias del Alto Mayo presentan caudales variados, desde 0.1 m3/s (resurgencia de Palestina), hasta 19.5 m3/s (naciente del Rio Negro). Con los valores de caudal obtenidos, se puede estimar que el macizo delAlto Mayo contribuye a mås de 48 % al caudal del rio Mayo (119 m3/s)

    (IF 6.44; Q1)International audienceKarst aquifers provide drinking water for 10% of the world’s population, support agriculture, groundwater-dependent activities, and ecosystems. These aquifers are characterised by complex groundwater-flow systems, hence, they are extremely vulnerable and protecting them requires an in-depth understanding of the systems. Poor data accessibility has limited advances in karst research and realistic representation of karst processes in large-scale hydrological studies. In this study, we present World Karst Spring hydrograph (WoKaS) database, a community-wide effort to improve data accessibility. WoKaS is the first global karst springs discharge database with over 400 spring observations collected from articles, hydrological databases and researchers. The dataset’s coverage compares to the global distribution of carbonate rocks with some bias towards the latitudes of more developed countries. WoKaS database will ensure easy access to a large-sample of good quality datasets suitable for a wide range of applications: comparative studies, trend analysis and model evaluation. This database will largely contribute to research advancement in karst hydrology, supports karst groundwater management, and promotes international and interdisciplinary collaborations
