Metode Analisis Hidrologi dan Pemanfaatan Bendungan

Sementara ini analisis hidrologi dan pemanfaatan bendungan hanya didasarkan pada Laporan Review Hidrologi Bendungan Leuwikeris dalam rangka penyempurnaan dan sertifikasi.  Disain Bendungan Leuwikeris (Oktober 2015). 

Ruang lingkup pekerjaan dalam kegiatan ini adalah sebagai berikut: 

  • Pengumpulan dan penelaahan semua data yang berkaitan dengan pekerjaan antara lain data curah hujan, klimatologi, debit aliran di sungai, Peta Topografi, Peta Tata Guna Lahan, Peta Hidrogeologi dan hasil studi lainnya yang telah dilaksanakan. 
  •  Analisis Banjir Rencana berbagai periode ulang dan PMF yag meliputi kegiatan : 
    •  Analisis Hujan Rencana periode ulang 2, 5, 10, 25, 50, 200, 500 dan 1000 tahun serta besaran hujan maksimum boleh jadi atau PMP (Probable Maximum Precipitation)
    • Pembuatan konfigurasi model banjir dengan model matematika hujan-limpasan 
    • Model Prediksi yang merupakan kombinasi hasil hujan rencana dengan hasil pemodelan banjir. 
  • Analisis Ketersediaan Air yang meliputi : 
    • Pengisian data hujan yang kosong 
    • Analisis Data Klimatologi untuk mendapatkan nilai evapotranspirasi 
    • Persiapan model ketersediaan air dan kalibrasi model 
    • Model Generating untuk membangkitkan data debit simulasi. 
    • Mengestimasi penggunaan air : Irigasi, Pembangkit Listrik Tenaga Air dan Air Baku untuk masyarakat. 
  • Simulasi Waduk yang mencakup aspek: 
    • Pembentukan model neraca air waduk 
    • Penentuan kapasitas tampung waduk efektif melalui berbagai macam skenario kebutuhan air dan kapasitas outlet dengan memperhatikan faktor keandalan waduk.

River Basins in Sabah

By
Figure 1 Rivers and Points Annual Rainfall at Sabah (After Sabah Water Resources Master Plan, 1995) The best source of information about river basins in Sabah is from the "Sabah Water Resources Master Plan", which can be seen at http://www.did.sabah.gov.my/ . The river basins are can be grouped as those that discharging the flow to the west coast, north coast, and to the east coast. Some rivers that go to west coast are: Sg. Mayog/Babogon Sg. Papar Sg. Padas Some rivers that go to the north coast are: Sg. Bandau Sg. Bangan/Kinorom Sg. Bengkoko/Pitas Some rivers that go to the east coast are: Sg. Liwagu Sg. Kinabatangan Sg. Tawau Sg. Merotai Besar The Figure 1 shows the points annual rainfalls and rivers in Sabah.

4. Logical Framework for Integrated River Basin Management

By
4.1 Introduction The logical framework approach (LFA) was first adopted by U.S. AID in the early 1970s. The framework provides a set of designing tools that, when used creatively, can be used for planning, designing, implementing and evaluating projects (the entire project cycle). The purpose of LFA is to undertake participatory, objectives-oriented planning that spans the life of project or policy work to build stakeholder's team commitment and capacity, through a series of workshops. The technique requires stakeholders to come together in a series of workshops to set priorities and plan for implementation and monitoring. This achieved by structuring the main elements of project in a matrix (the logical framework) which summarizes the project, highlighting logical linkages between intended inputs, planned activities and expected results and records the underlying assumption. See Figure 4.1, for the content of framework matrix and how to read the LFA. 4.2 Steps in Logic
