DAS Lesti, Kabupaten Malang mengalami alih fungsi lahan yang besar akibat pesatnya pembangunan di era modern ini sehingga mempengaruhi laju infiltrasi. Studi ditujukan guna mengetahui infiltrasi dengan Model Horton dan Philip, kemudian didapatkan model memiliki prediksi paling sesuai pengukuran lapangan. Pengambilan data berupa hubungan antara waktu besarnya penurunan air titik-titik menggunaka...

Sub DAS Lesti memiliki lahan kritis yang tinggi, karena penggunaan tidak sesuai potensinya. Perubahan untuk area pemukiman berdampak pada penutupan oleh permukaan impermeable, sehingga terjadi peningkatan limpasan air hujan dan berkurangnya nilai kapasitas infiltrasi. Untuk mengatasi permasalahan ini, diperlukan analisis karakteristik genangan. Air akan menggenang jika intensitas melebihi Anali...

In this research, an attempt was made to find the permeability of RC beam with AFRP by making use hydraulic conductivity test and a double-ring infiltrometer. Based on state-of-the-art methodology, three different samples, Kelvar 29, 49 149, were considered as laminates prevent deflection beams. Accelerated corrosion carried out using impressed current, induced calculated galvanostatic method. ...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract In the context of studies aiming at the estimation of effective parameters for unsaturated zone modelling, this work tackles the problem of experimental data quality, considering the large collection of data gathered at an experimental sit...

purpose: to describe a new noninvasive method to assure correct orientation of donor lenticules in descemet stripping automated endothelial keratoplasty (dsaek) surgery. methods: dsaek surgery was performed in three eyes with the diagnosis of pseudophakic bullous keratopathy (pbk). for the laboratory part of the study, two whole globes and two precut corneoscleral buttons were used. the donor l...

Water infiltration into the soil profile and runoff losses in arable lands are related to the condition of the top layer. The tillage treatment (included no-till) of the top layer plays a key role in changes of the hydro-physical properties, mainly saturated hydraulic conductivity (K) of the treated layer. This paper is focused on the influence of repeated tillage treatments in the same localit...

Infiltration is defined by the expression of hydraulic conductivity soil, which we decided to monitor on an experimental field applying a modern system land management (control traffic farming). The present study compared two different methods monitoring soil selected 16 ha plot in suburbs village Kolíňany (Slovak Republic). During growing seasons, crops such as oilseed rape, winter wheat, spri...

Permeable pavements are considered to be one of the effective measures for LID (i.e. Low Impact Development) and SUDS Sustainable Urban Drainage System) globally. The major three types permeable (a) pervious concrete (PC), (b) previous asphalt (PA), (c) interlocked paver (PICP). performance all is satisfactory at start service life but greatly reduced if not maintained on time. Considering long...
