Resumen
Los estudios de morfometría brindan información sobre el funcionamiento hidrológico en una cuenca. El objetivo del estudio fue determinar parámetros morfométricos en la subcuenca del rio Páez, Cartago necesarias para planificación de las actividades de la cuenca y para un apropiado manejo.
La construcción de la morfometría se basó en las curvas de nivel del Gran Área Metropolitana, escala 1:10000, y utilizando los Sistemas de Información Geográfica, se realizó la digitalización de las curvas de nivel, los drenajes y el parte aguas. Resultado del análisis morfométrico, se obtiene un
área de 28,34 km2 y un perímetro de 47,4270 km. Está compuesta por 22 microcuencas, un factor de forma de 0,1171indicando una subcuenca alargada. Un coeficiente de compacidad de 2,4942, indicando que es una cuenca elongada. Muestra una curva hipsométrica de tipo cóncava, donde el pico de la distribución altimétrica corresponde con las altitudes entre los 3315 m y los 980 m. El parámetro pendiente con un valor de 29,3% de pendiente promedio. Es evidente la función que cumple la subcuenca para el desarrollo de las actividades productivas y para el abastecimiento de agua potable en algunos sitios Cartago.
Morphometric studies provide information on the hydrological functioning in a basin. The objective of the present study was to determine morphometric parameters in the sub-basin of the Páez River, located in the province of Cartago, Costa Rica, necessary for land use planning within the basin and its proper management. Morphometric construction was based on the 1:10,000 scale contour lines available for the Gran Area Metropolitana (translated as the Greater Metropolitan Area) and geographic information systems utilized to digitalize contour lines, drainages and watershed. Resulting from the morphometric analysis, a sub-basin area of 28.34 km2 and perimeter distance of 47.4270 km were estimated. The sub-basin is comprised of 22 micro-basins and overall exhibits a form factor value of 0.1171, thus indicating an elongated sub-basin. A compactness coefficient value of 2.4942 indicates an elongated basin. The sub-basin exhibits a concave hypsometric curve, where the peak of its altimetry distribution corresponds to altitudes between 3315 m and 980 m. The slope parameter has an average value of 29.3% slope. It is evident the role played by the Páez River sub-basin for the development of productive activities and water supply of some localities in the province of Cartago.
