","ICRISAT’s intervention in the project “Improving Management of Natural Resources for Sustainable
 Rainfed Agriculture” funded by the Asian Development Bank aims to increase the productivity and
 sustainability of the medium and high water-holding capacity soils in the intermediate rainfall ecoregion of
 India, Thailand, and Vietnam. To implement this project ICRISAT selected five benchmark watersheds  three in India, one in Thailand, and one in Vietnam – to introduce improved crop production and natural
 resource management technologies. This work was carried out over three years (1999–2001) and promising
 results have been obtained on crop productivity gains as well as efficient use and conservation of natural
 resources. This report focuses on the impact of various watershed technologies on the surface and
 groundwater hydrology of the watersheds at all the five benchmark sites. The information on topography,
 rainfall, runoff, groundwater, and other relevant data were collected and analyzed. The hydrological data
 from the five benchmark watersheds clearly show the effectiveness of improved watershed technologies in

reducing runoff volume and peak runoff rate and improving availability of groundwater. The highest runoff
 volume of 433 mm (51% of seasonal rainfall) was recorded from the Tad Fa watershed in Thailand, while
 the lowest runoff volume of 55 mm (7% of seasonal rainfall) was recorded from the Adarsha watershed in
 Kothapally, India. The highest peak runoff rate of 0.235 m3 s-1 ha-1 was recorded from the untreated
 watershed at Kothapally. Among the three sites in India, the highest runoff was recorded at Lalatora
 watershed in Madhya Pradesh. The highest contribution of seasonal rainfall to groundwater was recorded at
 Lalatora watershed (270 mm or 29% of seasonal rainfall). The hydrological behavior and data reported in
 this report will be useful in the planning, design, development, and management of natural resources in the
 target regions.
