CONTENTS BACKGROUND NETWORK OF STATIONS OPERATED BY THE IDEAM HYDROLOGICAL STATIONS OF COLOMBIA TO WHAT INSTITUTIONS BELONG, HOW MANY TELEMETRIC STATIONS, FORMS OF TRANSMISSION, MARKS THE OPERATION OF THE NETWORK EXPERIENCES IN THE OPERATION OF THE NETWORK PLANS FOR THE FUTURE

BACKGROUND 1975 - Canadian International Development Agency (CIDA), they install 52 hydrological stations by Radio in the HF band in all the river basin of Magdalena and Cauca Rivers. 1984 – 1988 - (PNUD), (OMM), y (HIMAT), Rationalization of the Practical Applications of the Hydrology and Meteorology in Colombia - 32 stations. 2000 - Mixed line of Swiss Credit - 235 E.A.S and 355 RAN, basic hydrometric equipment (micro small mills, small mills, levels, malacates, eco-soundings, etc.) 2003 Courses of Co design of the Environmental Network. 2003 - 2006 Installation and implementation of the project
