Figure 3: Topography
Topography of Varada river catchment is as depicted in Figure 3, elevation ranges between 507m and 836m w.r.t Mean Sea Level, slope of the catchment varies up to 119%. The catchment has gentle slope flowing to the north eastern direction.
Due to the flatter terrain, numerous lakes (over 4000) in the catchment could be observed which serves as a reserve, recharge pit, for fish culture, agriculture and other activities.
Rock types: Granite, Schists, Porphyry, Chlorite, Limestone
Ores: Iron, Manganese, Limestone, Clay
Soil: Red Soil, Lateritic soils, Black soil, etc

Rainfall and Water Yield

Rainfall assessment in Varada catchment (Figure 4) indicates that rainfall in the catchment is orographic with annual rainfall varying spatially between 663mm at the plains of Haveri, to over 3600 mm at the Ghats of Sagar (Shimoga).
Water yield in the catchment is 40 – 80 TMC
