    The streams La Cristalina and La Risaralda are the water sources for the urban area of the Municipality of San Luis, Antioquia. The intention of this study was to develop a map of water quality that serves as base as comparison of the evolution of the streams and allows the high-priority destination of the resources of the Municipality in the improvement of those more critical sections. In order to determine the quality of the water, parameters and some characteristics of the stream that can alter the quality of the water were measured, like substrate of the bed, cover of banks, aquatic habitats, temperature, conductivity, oxygen, pH, coliforms, and aquatic macroinvertebrates. The indices calculated with base in the collected data were: BMWP, ASPT, ETP, Index of Diptera, and equity Index. With the data of the ASPT the map of water quality of both streams was elaborated. The streams are well oxygenated and the rocky conformation of its bed allows the diversity of aquatic macroinvertebrates, nevertheless, in some sections, they are subjected to contamination of domestic and farming origin, which limits their conditions of use.

    Modelamiento estocástico en la determinación de la oferta hídrica del río Source Matelas (Haití): aplicación al predimensionamiento de un embalse

    Source Matelas, located in the West State, Republic of Haiti, is a town with scarce economical resources and low quality of life, mainly because of the absence almost total of water. In this work we give a first approximation to a water reservoir pre-feasibility study, related to water supply quantification of the region, by means of hydrological methods to estimate unknown information. Long term components of the hydrological balance are calculated and daily mean yield that serves the model of reservoir simulation is estimated. The mean runoff calculated for the Source Matelas River is 0.026 m3/s. Based on reservoir modeling, volume needed to supply different percentages of the mean runoff is calculated. Therefore, it can be seen that population water demand will be supplied totally if a reservoir of 212000 m3 volume is constructed.
