Stormwater runoff is an issue that increasingly affecting urban areas because previously were permeable have been developed, and are now impermeable, comprising hard surface areas, whether concrete floors, roads, or buildings. As the size of problem area increases, amount stormwater needs to be cleared from it takes longer for cleared. The existing basic public drainage systems can no sufficien...

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...

Abstrak . Laju infiltrasi adalah kecepatan masuknya air ke dalam tanah dan tergantung pada kondisi tanah. Perkebunan kopi robusta tentunya memiliki beberapa tingkatan umur tanaman yaitu dari muda sampai dewasa. Akar yang matang mempengaruhi pori-pori di Keberadaan akar tidak hanya meningkatkan aktivitas mikroorganisme, tetapi juga semakin besar sehingga peluang besar. Penelitian ini mengkaji la...

analyses illustrated that the spatial structure estimate obtained from measurement scale SLIla was inconsistent with that obtained from measurement scale t+. Thus, we conclude that the infiltrometer instrument fundamentally alters the infiltration process in such a way that measurements are only meaningful in a relative sense. Steady-state infiltration rates were measured at three instrument sc...

plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...

abstract disc infiltrometer is one of those devices that used in recent years in measurement of hydraulic conductivity of entire soil. in order to analyze the data taken by disc infiltrometer a variety of methods based on wooding’s base analyze have been introduced. the objective of this study was to compare the performances of ankeny and weir methods for predicting soil hydraulic properties us...

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...
