River bed stability versus clogged interstitial: Depth-dependent accumulation of substances in freshwater pearl mussel (Margaritifera margaritifera L.) habitats in Austrian streams as a function of hydromorphological parameters

open access: yesLimnologica, 2015
Abstract Substrate conditions are considered crucial for the survival of juvenile freshwater pearl mussels ( Margaritifera margaritifera L.) – and therefore for the recovery of overaged populations in danger of extinction – as fine sediments can clog the interstitial habitat and hamper water and oxygen circulation to the juveniles.

Clogging of permeable pavements in semi-arid areas [PDF]

open access: yes, 2010
Urban development and consequently covering more areas by the impervious surfaces, has led to the decrease in natural process of rainfall infiltration and as a result deduction in ground water recharge.

Feasibility of subsurface drip irrigation for agricultural utilization of biogas slurry: A practice for arid regions in Northwestern China

open access: yesAgricultural Water Management
Water scarcity severely constrains agricultural sustainability in arid and semi-arid Northwestern China, while the rapid expansion of livestock production generates large volumes of biogas slurry (BS) that require safe and efficient reuse.
