This study aims to investigate tectonic activity levels and development stages of the tectonic and hydrologic basin areas located on western part of the main trace of the North Anatolian Fault Zone (NAFZ) using quantitative measurement techniques. The basins investigated are Bolu, Yeniçağa, Dörtdivan, Çerkes, Ilgaz and Tosya. The methodology includes application of six morphometric indices (Basin Shape, Hypsometric curve and Hypsometric Integral, Sinuosity of Mountain Fronts, Stream Length Gradient Index, Valley width to height ratio, and Asymmetry Factor) to Digital Elevation Model (DEM) of the region generated from 1:25000 scale topographic maps. The analyses indicate that the basins located in the study area have different characteristics of tectonic activity. According to the results of the applied indices relative order of the activity for tectonic basins is, in decreasing order, Bolu, Tosya, Ilgaz, Çerkes, Yeniçağa and Dörtdivan. For hydrologic basins, on the other hand, the same order is observed except for a swap in Çerkes and Yeniçağa basins. Among the basins located to the north of the NAFZ, the activity decreases eastward whereas to the south the fault zone it decreases towards the west.
