Peningkatan kebutuhan air untuk pertambangan nikel di Pulau Obi perlu analisa potensi Sumber Daya Air untuk memenuhi kebutuhan tersebut. Dalam hal inipenulis melakukan penelitian pada Danau Karo, Mata Air disekitar danau dan Sungai Akilamo. Untuk mengetahui potensi Danau Karo dilakukan analisa aliran permukaan terhadap DAS Danau Karo diakibatkan oleh hujan yang diperoleh dari data pengukuran presipitasi, evapotranspirasi, aliran dasar yang selanjutnya menentukan debit andalan dengan metode FJ. Mock. Debit Sungai Akilamo dan debit mata air disekitar danau dilakukan pengukuran debit secara langsung di lapangan dan untuk mengetahui kondisi visual tutupan lahan dilakukan dengan kamera Drone. Dalam makalah ini dilakukan analisa untuk mencari potensi sumber daya air di Pulau Obi menggunakan metoda F.J Mock DebitAndalan 95 % potensi Danau Karo 500 liter/det, dengan pengukuran debit insitu potensi Mata Air Kawasi 40 liter/det, Mata Air Uluwatu 48 liter/det dan Sungai Akilamo 10.000 liter/det. Konsep penampungan air sebelum didistribusikan dengan membuat kolam retensi yang berfungsi sebagai reservoir sekaligus dapat menyerapkan air kedalam tanah (Artificial Recharge) sehingga Siklus Hidrologi dapat terjaga.

Recharge Structures

Artificial recharge plays a prominent role in the sustainable management of groundwater resources. The study has proposed a methodology to viable artificial recharge structure using geographical information system (GIS) and empirical equation techniques for augmenting groundwater resources in the Ranchi urban and rural area of Ranchi District, Jharkhand. The thematic layers for geomorphology, drainage density, order of streams, runoff and trend has been prepared in the GIS environment using convection and remote sensing data. It has been found that the slope and topographic gradient of Ranchi region is one of the major governing factors, which restricts to hold surface water stagnant. Jumar watershed is found as the most feasible watershed for the construction of check dams/percolation tanks followed by Lower Subarnarekha watershed. Out of 15 deeper exploratory wells, 14 are declining. Harmu watershed is found to be in the worst condition in terms of availability of runoff water. Harmu, Kanke, Bariyatu, Namkum, Doranda, Hinoo and Hatia have found as the most suitable locations for installation of RTRWH within the Ranchi urban area. Based on the available field information, check dams are suggested as the most promising artificial recharge structures for Ranchi rural environment.
