Description
Summary:The Upstream Cibeet sub-watershed is part of the Citarum watershed and Cibeet sub-watershed with an area of 69.35 km 2 . Hydrologically, the upstream part of the watershed usually functions as a recharge area, and its development should be geared towards land conservation and erosion mitigation. Parameters of rainfall, soil type and texture, geology, lineament density, drainage density, geomorphology, and land cover are used in predicting the most potential catchment area. Thematic maps were made for each parameter. Weighting is carried out using the Analytical Hierarchy Process (AHP) with the following results: rainfall 0 %, soil type and texture 34.62 %, geology 24.98 %, lineament density 17.66 %, drainage density 8.57 %, geomorphology 9.34 %, and land cover 4.83 %. The integration of each thematic map resulted in a map with four zonations, namely zone of poor (4.93 %), fair (32.67 %), good (60.58 %), and very good (1.81 %) recharge potential. Based on the groundwater table contour, groundwater mimics the surface topography and flows from the south to the north and northeast part of the study area. Geological structures in the study area possess a NE-SW and NW-SE trend with a normal oblique regime. Structural damage zones are predicted to function as conduits for water movement, especially in volcanic and intrusion lithology.
