Abstract

Water is the most basic requirement that is necessary for a good life on land, sea or air. Water in the face of this earth are not directly derived from the rain. All living things need water to survive. Water management should be done as quickly as possible so that its availability is maintained. Along with the development of the times and increasing daily population in Indonesia, the demand for water continues to increase. Indonesia has a tropical climate with two seasons, the dry season and the rainy season. During the dry season of drought, while in the rainy season floods. One reason is the change in land use that result in water catchment areas disappear and be replaced by buildings some hydrological model was developed to determine the water balance, such as infiltration models. Infiltration models are used to determine how much of the surface runoff or inundation (ponding) which can be infiltrated. The purpose of this study is to analyze the model's ability to absorb water in a simple infiltration runoff, infiltration simple models to analyze the influence of the flow between, to analyze the efficiency of a simple infiltration models to infiltration, and a simple model to analyze the influence of water turbidity in a state of unsaturated and saturated water. The results showed that the soil with plants media can reduce runoff and improve water quality due to rain than vacant land. Discharge runoff on bare ground while unsaturated and saturated water of 0.136 liters/sec and 0.134 liters/sec, while on the ground with the current crop of media unsaturated and saturated water at 0.1330 liters/sec and 0.1300 liters/sec. The content of the suspension on a vacant lot when unsaturated and saturated water is 6.88; 4.20; 3.94 mg/l and 2.13; 1.66; 1.11 mg/l, while in the soil with the current crop of media was saturated and saturated water is 4.40; 4.22; 2.35 mg/l and 0.92; 0.83; 0.63 mg/l.

Abstract

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 750×30×20cm 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.

Abstract

Penanganan run off dengan secepat cepatnya cenderung hanya menyelesaikan masalah pada sub DAS tersebut dalam jangka  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.   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 ini  menjadikan berubahnya kedalaman, radius hidraulik dan kecepatan aliran. Penghitungan kecepatan secara teoritis dilakukan dengan persamaan manning pada sungai sebelum dan sesudah ada tanggul. Besarnya perubahan diperoleh dengan membandingkan kedalaman, radius hidraulik, dan kecepatan sebelum dan sesudah ada tanggul.Hasil analisis yang telah dilakukan dari kondisi tanpa tanggul menjadi dengan tanggul untuk Q5 tahun : di P 394 tinggi muka air naik 5,861%, radius hidraulik naik 6,947% dan kecepatan air naik 19,523%. Pada P 249  tinggi muka air naik 4,327%, radius hidraulik naik 7,405% dan  kecepatan air naik 19,808%. Pada P 170 tinggi muka air naik 7,657%, radius hidraulik naik  9,708% dan kecepatan air naik 21,527%.

Abstract

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.  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.
