Abstract:

The local hydrological, agricultural and economic activities heavily depend on micro-level rainfall. Therefore, this study examines the variability of rain fall in Wargal sub watershed in Siddipet district, Telangana state of India. To study the rainfall variability within the study area of 15 sq km, 15 rain gauges were installed at different locations and data was collected during July and August months, 2009. The rainfall variability map was generated by using GIS software. The weather data was collected by installing the related instruments at Nagarjuna Innovation Centre, Wargal during Sep 2008. It was observed that relatively higher rainfall (310 to 340 mm) was received in areas around lower reach (Kothakunta and Bitcherla kunta tanks) and relatively lower rainfall (250 – 280 mm) was received in areas around upper reach (Melakunta and Kadelakunta tanks).The areas around middle of watershed (Ausoloni kunta and Ayamgori kunta) received relatively moderate rainfall (280 – 310 mm). The rain fall variation was greater in August than July months. During August month most of the rain fed crops of 90-110 days was in reproductive stage and any deficit cause variability yield in the same sub watershed as that observed in Kothakunta sub watershed.
