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...

The present study was conducted on the Tondibiya and Satara plateaus, in Ouallam department (western Niger). objective is to sedimentation dynamics of soil particles deposited sylvopastoral half-moons different years (2014, 2016 2018). assessment done selected following a survey transects. It involved determination thickness sedimented horizon, measurement permeability by single ring infiltrome...

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...

We devised a simple infiltrometer to easily assess soil infiltration capacity and key hydraulic properties considering the impact of structure on infiltration. conducted two series five in situ experiments each undisturbed forest grassland contrasting bulk densities saturated conductivity (Ks), one six columns with mineral various textures without structure. Finally, we measured Ks, water conte...

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. ...

Measuring infiltration and leaching at the plot scale is difficult, especially for high hydraulic conductivity soils. Infiltration rate has been indirectly calculated at the plot scale by comparing surface runoff to rainfall. Direct measurement of infiltration and leaching beyond the point scale is typically limited to locations where land forming has been performed, e.g. infiltration ponds and...

A parameter estimation procedure, sequential uncertainty domain parameter fitting (SUFI), is presented and has the following characteristics. The procedure is sequential in nature, meaning that one more iteration can always be made before choosing the final estimates. The procedure has a Bayesian framework, indicating that the method operates within uncertainty domains (prior, posterior) associ...

Data collected at two measurement scales from a semiarid grassland are presented and analyzed to explore the hydrologic effects of grazing, interactions between overland flow and infiltration, and scale issues. Rainfall-runoff simulations were used to quantify the areal ~3 by 10 m plot scale! response, and small-diameter ~9 cm! disk infiltrometers were used to estimate point-scale hydraulic con...
