The lowlands in northeast Germany are among the driest and at the same time the most densely wooded regions in Germany. Low annual precipitation between 500 and 600 mm and the light sandy soils with their low water storage capacity and high porosity lead to limited water availability. Therefore the hydrological functions of forests play an important role in the fields of regional water budget, ...

The weighing lysimeters provide scientist the basic information for research related to the evapotranspiration, high quality of the collected data from lysimeters is of great significance. However there are many factors that can affect the measurement accuracy of the weighing lysimeter. In this paper, a data acquisition system was developed to collect the data from 24 weighing lysimeters. The c...

ABSTRACT The fundamental understanding of hydrogeochemical processes leading to toxic drainage in mining environments is utmost importance predict the impact activities waste facilities and design effective measures for mitigation environmental risk. This study investigates weathering behavior different types mine rocks, with considerably mineralogical textural properties, by performing long-te...

Soil microorganisms colonizing soil water sampling devices (lysimeters) reduced concentrations of biodegradable organic chemicals, including 2,4-dichlorophenoxyacetic acid methyl ester, alachlor, methyl m-chlorobenzoate, and metolachlor as water entered through porous ceramic cups. In some cases, losses exceeded 99%. Additions of either a biocide (sodium hypochlorite) or a bacteriostat (copper ...

Landfill covers are critical to waste containment, yet field performance of specific cover designs has not been well documented and seldom been compared in side-by-side testing. A study was conducted to assess the ability of landfill final covers to control percolation into underlying waste. Conventional covers employing resistive barriers as well as alternative covers relying on water-storage ...

The purpose of this model is to enable implementation of the theory of linear systems control in operational management of waste and fertiliser applications onto land, so that the underlying groundwater is protected from pollution by leachate. The state-space form of the model enables use of the extensive theory and available software on stochastic linear S)lstCms. In particular, the Kalman fil...

Orange peel (OP), the main residue of citrus industry, is usually used for animal feeding and soil fertilisation if more advanced options are lacking. In areas with warm dry climatic conditions, OP land-spread solar-drying on fields, leachate produced a potential pollution factor especially due to release organic matter; heavy rainfalls could even aggravate hazard. Since literature does not rep...

Rainfall–runoff responses were observed in a laboratory environment using rainfall simulator and 7.43 m2 green roof cassette equipped with weighing lysimeters. SWMM LID controls developed for various profile configurations based on the physical properties of composite materials. Unknown parameters affecting drainage layer adjusted calibration. The was modeled both as typical Green Roof control ...

The U.S. Department of Energy Office of Legacy Management is investigating alternatives to conventional cover designs for uranium mill tailings. A cover constructed in 2000 near Monticello, Utah, USA, was a redundant design with a conventional low-conductivity composite cover overlain with an alternative cover designed to mimic the natural soil water balance as measured in nearby undisturbed na...
