Roofing materials as source of runoff pollution : pilot scale experiments for the assessment of material contribution Universiteit Gent
Wind-driven rain and runoff on a medium-rise building: experimental and numerical analysis KU Leuven
As wind-driven rain (WDR) is one of the most important moisture sources for a building envelope, a reliable prediction of the WDR and runoff load is a prerequisite to assess the durability of building facade components. Current state-of-the-art Heat Air and Moisture (HAM) models neglect the influence of runoff. This study contributes to research efforts to develop models that combine state-of-the-art HAM models with a runoff model. It ...
Rainwater harvesting to control stormwater runoff in suburban areas. An experimental case-study Vrije Universiteit Brussel
On a 23 ha urban watershed, 10 km East of Paris, rainwater tanks have been installed on 1/3 of the private parcels to prevent stormwater sewer overflows. This paper investigates the macroscopic effect of rainwater harvesting on runoff, and thus the potential of this technique for stormwater source control. The analysis is performed using the SWMM 5 model, calibrated on rainfall- runoff measures from two measurement campaigns, before and after ...
Impact, runoff and drying of wind-driven rain on a window glass surface: Numerical modelling based on experimental validation KU Leuven
This paper presents a combination of two models to study both the impingement and the contact and surface phenomena of rainwater on a glass window surface: a Computational Fluid Dynamics (CFD) model for the calculation of the distribution of the wind-driven rain (WDR) across the building facade and a semi-empirical droplet-behaviour model. The CFD model comprises the calculation of the wind-flow pattern, the raindrop trajectories and the ...
Urban Spatial Configuration and Functional Runoff Connectivity: Influence of Drainage Grid Density and Landscape Metrics Vrije Universiteit Brussel KU Leuven
Due to changing precipitation patterns induced by climate change, urban planners are confronted with new challenges to effectively mitigate rainfall runoff. An important knowledge gap that needs to be addressed before tackling these challenges is how and to which extent street/drainage grid density and spatial land use configuration influence the amount of runoff. Therefore, a virtual experiment was conducted to assess the influence of grid ...
Report on the effectiveness of vegetative barriers to regulate simulated fluxes of runoff and sediment in open agricultural landscapes (Flanders, Belgium) Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Vegetative barriers are increasingly used to reduce sediment export from cropland and thus mitigate negative off-site consequences of soil erosion. Here, we report and discuss the effectiveness of vegetative barriers implemented in Flanders (Belgium) to buffer the flows of water and sediment. The three types of vegetative barriers studied are made of straw bales, wood chips or bales of coconut- fibre. Based on three simulated runoff experiments ...
Controls on dissolved organic carbon export through surface runoff from loamy agricultural soils KU Leuven Universiteit Antwerpen
Dissolved organic carbon (DOC) is one of the most active and mobile carbon pools, and thus an important component of the global carbon cycle. Previous research on DOC transport in the soil and on factors controlling DOC export towards the river systemfocused mainly on forest andwetland areas, with only limited information available from agricultural soils. We carried out rainfall simulations on agricultural field sites to identify the effect of ...
EVALUATION OF BIOLOGICAL GEOTEXTILES FOR REDUCING RUNOFF AND SOIL LOSS UNDER VARIOUS ENVIRONMENTAL CONDITIONS USING LABORATORY AND FIELD PLOT DATA KU Leuven
Preliminary investigations suggest biological geotextiles could be an effective and inexpensive soil conservation method, with enormous global potential. However, limited quantitative data are available on the erosion-reducing effects of biological geotextiles. Therefore, the objective is to evaluate the effectiveness of biological geotextiles in reducing runoff and soil loss under controlled laboratory conditions and under field conditions ...
Impact of subsurface rock fragments on runoff and interrill soil loss from cultivated soils KU Leuven
Field and laboratory studies have indicated that rock fragments in the topsoil may have a large impact on soil properties, soil quality, hydraulic, hydrological and erosion processes. In most studies, the rock fragments investigated still remain visible at the soil surface and only properties of these visible rock fragments are used for predicting runoff and soil loss. However, there are indications that rock fragments completely incorporated in ...
