%X Samigaluh and its surrounding area in West Progo Regency is a part of West Progo Hills 
physiographic zone that has steep denudational hilly morphology. Field geomorphological survey has 
been conducted in this area to reveal the landscape characteristics quantitatively. Quantitative 
geomorphology study was conducted on the dimension or morphometric of landscape at some 
location of hills and streams. Morphometric aspects that have been analyzed include elevation (h) and 
slope (α) of regions or hills as well as some response variables of stream morphology that include 
valley floor-height ratio (Vf), valley cross section (Vr), river gradient index (SL) and drainage density 
(Dd). The results showed that the response variables of morphology in the study area have variation in 
values. Average value of elevation (h) is 415 m, slope is 42.2%, Vf is 1.04, Vr is 0.68, SL is 180.7 
and Dd is 0.38 / km2
. Analysis of the relationship between several variables of morphometry showed 
the low to very low correlation value, with the highest correlation value is 21.29% only shown by the 
relationship between elevation (h) to valley floor-height ratio (Vr).
