Abstract

This research was conducted in the Kampar Regency, Riau Province was located at coordinates including 01 ° 00 '40 "- 00 ° 27' 00" S and 100 ° 28 '30 "- 101 ° 14' 30" E. The purpose of this research is to determine the watershed based on geological condition, geomorphological condition, amount of watershed division, relationship with rainfall, the relationship of geology, and geomorphology. The methods used are rock sampling, core description, geological data analysis, geomorphological and watershed analysis, rainfall analysis. Based on the analysis of the distribution of geological data in the watershed, there are 10 geological formations from geological mapping, namely: Sihapas formations, Telisa formation, Bekasap formation, Bahorok formation, Petani formation, Manggala formation, Talang Akar formation, Upper Telisa formation, Central Palembang formation, Basements, members of Lower Palembang formation (Air Berakat), members of the Upper Palembang formation (Muara Enim). There are 8 wells in the subsurface geology on the research area with 2 correlations, of the 2 correlations was known the subsurface geology state of this research area has a sediment deposition pattern in the form of repetition graded-bedding and cross bedding. The CR-04, CR-03, CR-01, CR-02, CR-08 as correlation 1 and the CR-05, CR-06, CR- 07 as correlation 2,. The geomorphology conditions are flatland area, low hilly area, hilly area, and high hilly area. Kampar and Siak are the names of the watershed in the research area. In the 5 years(2015-2019), the intensity of rainfall is fluctuation.
