摘要

克鲁图卡河有59.51平方公里(16英里)长,流入马拉卡海峡。克鲁图卡河经历了河流条件的变化、土地监管和人口增长,导致河流不再最佳运行。克鲁图卡河的洪水造成了建筑、农田和环境的破坏。这种情况发生在庇迪区,特别是克鲁图卡河流域。本研究旨在分析克鲁图卡河的体积能力,它利用5.0 - 3的HEC-RAS计划(5.0 - 3)和解决沿河洪水问题的方法,利用Q2、Q5、Q10、Q25到Q50年。使用的方法是个案研究。研究地点是Pidie区的Sigli镇Krueng Tukah,这是亚齐通过地形调查和直接观察河流状况和采访获得的主要数据。二级数据来自库玛拉、杜威镇洗衣场和蒂吉巴地的库玛拉降雨量。研究表明,R2的降雨量为94.85 mm, R5= 125.56 mm, R10= 48.65 mm, R25= 181.21 mm, R50= 211.82 mm。洪水流量为Q2= 59.28 m3/det, Q5= 96.05 m3/det, Q10= 123.71 m3/det, Q25= 155.52 m3/det和Q50= 201.47 m3/det。计算表明,克鲁图河不能容纳超过25年的洪水。保留河和水池的正常化是必须采取的应对克鲁格河洪水的措施。河的船员,方位55.51平方公里,朗斯河向马拉卡海峡下游25公里。船员们在河中经历了变化,土地使用,人口增长,所以这条河不再优化。随波逐流使建设、农业土地和环境受到损害。这发生在Pidie地区,尤其是驼峰地区。这一研究表明,这一研究将分析这条河的总资源资源回集集Q2、Q5、Q10、Q25至Q50年与HEC-RAS 5.0.3个程序和提供解决这条河问题的方案。使用的方法是一个案例研究。研究地点是亚齐皮迪区西格利市的Krueng tucations。主要数据由地形调查和地形观察的干扰。这是rainfall数据的形式,来自库马拉站、仓库市和巴吉市。results显示R2 rainfall是94.85 mm, R5 = 125.56 mm, R10 = 48.65 mm, R25 = 181.21 mm, R50 = 211.82 mm。排出流是在Q2 = 59获得28 m3 / sec, Q5 = 96。05 m3 / sec, Q10 = 123 71 155 / sec, Q25 = m3。52 - sec和Q50 m3 = 201。47立方米/ sec。《calculation results,是那个《Krueng Tukah河是多架to accommodate floods for more than Q25岁月。处理正常的河流和保留的浮桥是一种解决必须完成的Krueng河的办法。

Aplikasi Program HEC-RAS 5.0.3 Pada Studi Penanganan Banjir
Sungai Krueng Tukah memiliki DAS 59,51 Km2 dan panjang 25 Km serta bermuara di Selat Malaka. Sungai Krueng Tukah mengalami perubahan  kondisi sungai, tataguna lahan dan pertumbuhan penduduk sehingga sungai tidak lagi berfungsi secara optimal. Banjir pada Sungai Krueng Tukah menimbulkan kerusakan bangunan, lahan pertanian, dan lingkungan hidup. Hal ini terjadi di Kabupaten Pidie, khususnya di Daerah Aliran Sungai (DAS) Krueng Tukah.
