“…Namun karena debit resapan kecil, maka sumur resapan dan biopori kurang efektif untuk mengatasi permasalahan banjir (Joko, 2014;Hari, 2019;dan Edi, 2014). Dengan demikian diperlukan inovasi sumur resapan yang memiliki daya resap yang cukup besar (Edy, 2018). Penggunaan sumur untuk pengisian air tanah telah dilakukan oleh beberapa negara antara lain di Lahore (Fiaz, et.al, 2019).…”

Perubahan tataguna lahan yang menjadikan permukaan tanah semakin kedap menyebabkan penurunan infiltrasi air tanah dan peningkatan debit aliran permukaan. Berbagai upaya yang dilakukan dengan menggunakan sumur resapan dan biopori belum mencapai hasil yang diharapkan. Pipa resapan horisontal diharapkan menjadi salah satu solusi untuk mengatasi permasalahan tersebut. Dengan menggunakan pipa horisontal dinding berlubang panjang 2 m sampai 7 m diameter 10 cm diperoleh pengaruh variabel panjang terhadap debit resapan air di dalam tanah. Debit resapan air dengan pipa horisontal diameter 30 cm, panjang L cm, rasio lubang dinding 0.028, dan tinggi tekan air H cm pada tanah jenis clay dengan permeabilitas 7.09 x 10-6 cm/detik dinyatakan dengan persamaan Q=0.00019xL0,913 xH2.3965 . Debit banjir pada sebuah DAS dihitung dengan rumus Rasional dan kebutuhan pipa resapan horisontal dapat diperoleh dengan menggunakan grafik. Penggunaan pipa resapan horisontal dengan spesifikasi lain dan jenis tanah yang berbeda perlu dilakukan pengembangan penelitian. Hasil penelitian ini diharapkan dapat digunakan untuk memelihara konservasi air sekaligus penangan permasalahan banjirKata kunci: pipa resapan horisontal, konservasi, banjir

“…Additionally, numerous studies have been carried out on the utilization of infiltration wells for flood reduction [4]- [6], infiltration boxes [7], infiltration trenches [8], radial wells [2], and ponds [9]. The use of infiltration wells to reduce flooding is ineffective [10] due to the relatively small recharge [11]. However, it can be effective for groundwater recharge with 2 m depth or more [12].…”

Population growth and urban development have led to a widespread urbanized land cover leading to a direct increase in surface runoff and a decrease in groundwater infiltration. Various efforts have been carried out in many cities and countries using recharge wells and other structures, to increase groundwater replenishment and decreased flood discharge. This effort succeeded in increasing the groundwater level but was less successful in reducing flood discharge. This study analyzed the use of perforated pipe for groundwater recharge and runoff reduction. The research aims to formulate the infiltration rate into the soil through a perforated horizontal recharge pipe from a full-scale physical model. The research was conducted using 6 pipes of 7.5 cm-30 cm in diameter, 6 types of pipe length between 200 cm-700 cm, 6 values of pipe wall porosity (0.012; 0.016; 0.020; 0.024; 0.028; and 0.032), on texture clay soils with 4 types of soil permeability (3.49x10-6 cm/sec; 7.08x10-6 cm/sec; 8.93x10-6 cm/sec; and 1.12x10-5 cm/sec). The recharge test was carried out under the pipe flow condition (water level above the groundwater level and the pipe is underneath). Observations were used to analyze the influence of 5 variables (water pressure height, pipe diameter, pipe length, wall porosity, and soil permeability) of the perforated recharge pipe by using criteria of correlation coefficient Rsquare, RMSE (Root Mean Square Error), Cp (capability) to achieve the fittest model. The result showed that all variables affect the rate of groundwater filling. Based on a comparison of prediction recharge and observation visually, statistic parameter, and difference index the best-fitted model for perforated horizontal recharge pipe is a non-linear multiple power regression with an R-square 0.8878. This formula has also been compared with the Torricelli formula (R-square 0.5034) and the Forchheimer formula (R-square 0.7647) with more suitable results. So that research on perforated horizontal recharge pipes can be used more broadly, it is necessary to research recharge pipes on other texture of soil and research recharge pipes with the position of pipes under the groundwater level.
