Forestry operations can significantly alter hydrological and erosional processes in a catchment. In the course of developing timberland, a network of persistent roads and skid trails causing soil compaction is usually established. Hereby, the infiltration rate of the soil is distinctly reduced, which leads to the generation of overland flow—this may also cause soil erosion. In this study, a sma...

Understanding hillslope runoff response to intense rainfall is an important topic in hydrology, and is key to correct prediction of extreme stream flow, erosion and landslides. Although it is known that preferential flow processes activated by macropores are an important phenomena in understanding runoff processes inside a hillslope, hydrological models have generally not embraced the concept o...

Soluble salts, nutrients, and pathogenic bacteria in feedlot-pen runoff have the potential to cause pollution of the environment. A 2-yr study (1998-1999) was conducted at a beef cattle (Bos taurus) feedlot in southern Alberta, Canada, to determine the effect of bedding material [barley (Hordeum vulgare L.) straw versus wood chips] and within-pen location on the chemical and bacterial propertie...

Rainfall simulation experiments are widely used to study erosion and contaminant transport in overland flow. We investigated the use of two rainfall simulators designed to rain on 2-m-long (2-m2) and 10.7-m-long (32.6-m2) plots to estimate overland flow and phosphorus (P) transport in comparison with watershed-scale data. Simulated rainfall (75 mm h(-1)) generated more overland flow from 2-m-lo...

Extreme climate events are expected to occur very frequently and intensively with change, such extreme can induce irreversible damage plants soils, as well ecosystems. Accordingly, there is a need understand the effects of on Here, we designed temperature precipitation manipulation system simulate heat, drought, heavy rainfall. We constructed three soil surface levels (control, 3 °C, 6 °C incre...

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 ...
