Stream Research and Data
Estación Maritza is located near the banks of the Río Tempisquito, and within easy walking distance of five other permanent streams that are all tributaries of the Río Tempisque.
These streams have been the focus of many of our studies of stream ecology and biogeochemistry. Our efforts have also extended to permanent and temporary streams near other research facilities such as Santa Rosa, Cacao, San Cristóbal, and Pitilla.
|Stream||Catchment area (km2)||Mean streamflow (m3/s)||Run-off (m/yr)||Elevation range (m)|
|Río Tempisquito Sur||3.11||0.42||4.3||580-1250|
|Quebrada El Jobo||0.55||0.025||1.4||590-1040|
Data for streams of the ACG (primarily Río Tempisquito and Quebrada Marilin near Estación Maritza) include physical, chemical, and biological variables.
