Other watersheds at a larger scale are also monitored. (i) Soreda Halla which is about 43 km2 and (ii) Nugu Hole which is about 561 km2. All those watersheds are sub-basins of the Kabini watershed.

Soreda Halla watershed

Mule Hole is a sub-basin of Soreda Halla. However it was not possible to monitor Soreda Halla level after the confluence, so it is monitored 100 m upstream.

  • Stream water level used to be monitored every 15 minutes. However the bridge has been damaged and is going to be rebuilt soon, so the data logger was removed.
  • Stream sample (1-liter bottle) is taken every time we go for field trip and there is a flow event.

Nugu Hole watershed

  • Stream water level is monitored every 15 minutes at Rampura bridge.
  • Stream sample (1-liter bottle) is taken every time we go for field trip and there is a flow event.

Kalkere forest check post

This checkpost is located in the forest about 10km away of Rampura bridge.

  • Rain samples : manually collected by the check post staff each day it is raining.
  • Precipitations measured daily at the check post by the staff.

Mananthavady (Wayanad district, Kerala state)

In july 2007 IFCWS started monitoring hydrologic, geochemistric and climatologic datas at Payodd near Mananthavady in Wayanad district. The site is located near the Kabini river, and the stream flowing at Payodd is a tributary of the Kabini.

  • Stream sample, groundwater (from a dugwell) and rain samples: manually collected by the owner of the land.
  • Stream water level is measured manually by the owner of the land.
  • Precipitations measured by an automatic raingauge (HOBO® Datalogger).
