Rohmatulloh, Muhammad Adib (2017) Analisa Aliran Airtanah dengan Menggunakan Software GMS 4.0 di Kecamatan Mojowarno Kabupaten Jombang. Sarjana thesis, Universitas Brawijaya.
Abstract
Kecamatan Mojowarno terdapat 10 sumur bor yang di manfaatkan untuk irigasi, dengan kondisi 7 sumur berfungsi dan 3 tidak berfungsi dikarenakan alasan operasional dan penurunan muka airtanah. Penurunan muka air tanah pada daerah studi ini menggunakan analisa FEMWATER pada program Groundwater Modelling System (GMS) 4.0. dimana output dari program GMS 4.0. adalah sebaran dari nilai pressure head, total head, dan kedalaman muka airtanah. Simulasi yang dilakukan pada penelitian ini adalah simulasi sumur bor yang masih berfumgsi untuk perkembangan kebutuhan wilayah studi kedepan dan dampak jika sumur yang tidak berfungsi akan difungsikan kembali terhadap sumur bor yang lain. Pada kondisi simulasi pengaktifan kembali sumur yang tidak berfungsi mengakibatkan tekanan berkurang secara keseluruhan. Sumur SDJB 522 menurut hasil pemodelan GMS 4.0 bisa dikatakan aman atau dapat difungsikan kembali dikarenakan posisi muka airtanah masih berada jauh di atas screen sumur, sedangkan untuk sumur SMJB 297 dan SMJB 375 bisa dikatakan belum memenuhi untuk difungsikan kembali dikarenakan posisi muka airtanah sudah mendekati screen paling bawah sumur bor. Akan tetapi, sumur SMJB 297 dan SMJB 375 bisa difungsikan atau dioperasikan kembali jika jadwal pengoperasian sumur dilakukan secara bergantian.
English Abstract
Mojowarno has 10 wells that utilized for irrigation, which is consist of 7 functioning wells and 3 not functioning wells due to the operational and groundwater subsidence reasons. The calculation of groundwater level decrease in this study area were using FEMWATER analysis in program Groundwater Modeling System (GMS) 4.0. Which is the output of the program GMS 4.0 was the distribution value of the pressure head, total head, and groundwater depth. The simulation that conducted in this research is the simulation of borehole that is still fuming for the development of future study for the area needs and the impact of the unfunctional wells will be re-functioned to another borehole. In the simulated condition of unfunctional well reactivation, resulted the pressure reducing of totally. SDJB 522 wells according to GMS 4.0 modeling results can be said it's safe or could be re-functioned because the groundwater position is still far above the well screen, meanwhile for the SMJB 297 well and SMJB 375 can be said not yet fulfilled to function again because the groundwater position already close to the base Bottom of drill well. However, the SMJB 297 and SMJB 375 wells can be functioned or re-function if the operation schedule is conducted alternately.
