Drainage isasewer system in an areathat serves todrain excess rainfall. Initially, an artificial drainage channel could absorb water because the drainage channel is made from landorland with grass. Negative impacts frequently occurrence on the channel walls that are eroded by water see page. While the current drainage channel is impermeable, making direct runoff flows rapidly into water bodies. Land use is increasingly impermeable resulting bigger runoff and causing negative impacts, such as floods and decreasing groundwater savings due to rainfall directly flows into water bodies orriver nearby. In this paper, authortried tomake adrainage channel innovation by making boxes infiltration along the concrete channel. The aim of the study is to determine the effect of artificial recharge box modeling along drainage channels in reducing runoff using wastel and and grintinggrass(Cynodondactylon) media, determine the ratio of absorptionability between box wastel and media and Grinting grassmedia in reducing runoff using concrete channel/watertight as a reference. The model is made of wood with the size of 750Ã30Ã20cm and 5catchment box made every distance of 100cm along the channel, then the water flowed into the channel for an hour, and velocity data taken every five minutes before and after the flow through the box and also water level data taken every five minutes. The result shows that artificial recharge box with wasteland media can reduce runoff entering the channel, with the ability to reduce runoff at first hour about of 38.322% and it will decrease every hour, on it is smallest on the fourth hour 4 about of 28.038%. Also, a model with grintinggrass media can reduce runoff and the largestefficiency value is about 49.744% in first hour. Channel modeling with artificial recharges box using grinting grass media is better than only using wasteland for reducing.

Penanganan run off dengan secepat cepatnya cenderung hanya menyelesaikan masalah pada sub DAS tersebut dalam jangkaÂ pendek dan akan memberikan resiko banjir pada daerah yang lebih hilir. Dalam jangka panjang dimungkinkan banjir juga akan bergeser pula pada sub DAS tersebut juga.Â Â Penyelesaian banjir yang sekarang sering dilakukan adalah normalisasi sungai. Salahsatu unsur normalisasi sungai adalah pemberian tanggul sungai. Tujuan. penelitian ini adalah mengetahui perubahan kecepatan akibat pembuatan tanggul.Tanggul berguna untuk memperlancar aliran sungai dan mengganti fungsi bantaran sungai menjadi lahan pemukiman. Dinding tanggul umumnya terbuat dari bahan yang lebih halus daripada dinding alam sungai. Perubahan kekasaran sungai iniÂ menjadikan berubahnya kedalaman, radius hidraulik dan kecepatan aliran. Penghitungan kecepatan secara teoritis dilakukan dengan persamaan manning pada sungai sebelum dan sesudah ada tanggul.

Nowadays, the environmental problems that often occur are flood in wet season and drought in dry season. This happens because the rainwater runoff cannot seep into the ground well and the ground water level is decreased.Â Excessive surface runoff can be reduced by a simple water infiltration wells on the land. To determine the efficiency of absorption well, a model was created using infiltration rainfall simulator unit to create the condition of heavy rain. This study aims to analyze the relationship between times and several parameters: soil moisture, the changes in the groundwater table, the runoff time, the volume of rainfall infiltration, and to determine the reliability of models with changes in water table. The study was conducted using the infiltration model unit which was made of steel plate with a size of 170x170x200 cm3. This model is divided into three spaces. The first space, which its size is 150x150x200 cm3, has two tests. The first one is labeled as A test and filled with medium silt with the elevation of -150 cm. The B test is filled with medium clay with the elevation of -125 cm. The second space, with the dimension of 170x20x200 cm3, is used to control the ground water level. The third space is used for measuring absorption capability and has dimension of 30x30x100 cm3. This model has nine holes on each side for measuring soil moisture and the 12th hole underneath is used for measuring changes in ground water level. After the artificial rain descended for 120 minutes, soil moisture and ground water level changes measured in every 10 minutes.

This study aimed to determine changes in ground water level against time to recharge the unit models with medium sand soil in cloudburst conditions, to determine the effect of changes in humidity land in heavy rain conditions and for the efficiency of the model unit catchment .. By using the model infiltration unit made from box 170x170x200 cm3 and infiltration well with dimensions of 30x30x100 cm3 filled with 90 cm thick layer of sandy soil . The results showed that changes in ground water level is 18.8 % , 22.4 % and 24 % for the test I, II, III , respectively .. Soil moisture for the test I ran to saturation at 110 minutes , while for II and III trials in the 90th minute . Unit efficiency filtration models in improving the soil surface water is 3.6 % . This suggests that these filtration units of the model can reduce surface water runoff and increasing groundwater levels.Â

The alteration in land use causes the loss of infiltration areas replaced by rigid pavement yet demand for groundwater is increasing thus unbalance in hydrology cycle occurred and water became the problem for human as the problem for this country nowadays. One of the solutions to keep the storage of groundwater is to make the rain garden in the area near the run-off sources. Nonetheless studied about rain garden only focus on the effect of pollution in the river and study about the impact of reducing run-off debit and turbidity has not been explored yet. Three infiltration models that had been used for this research were infiltration model with soil-only, rain garden, and the rain garden with infiltration hole. The results presented by the study were compared to get the efficient value from each infiltration model in reducing debit and turbidity in the unsaturated and saturated soil. The result of this study showed that the rain garden model with infiltration hole performed better result with unit time reliability for 3 minutes and higher efficiency value of 54.17% on unsaturated soil and 53.81% on saturated soil. It can also reduce the suspension in the surface run-off until 0 mg/l.
