Rain water runoff from porous building facades:implementation and application of a first-order runoff model coupled to a HAM model KU Leuven
Wind-driven rain (WDR) is one of the most important moisture sources for a building facade. Therefore, a reliable prediction of WDR loads is a prerequisite to assess the durability of building facade components. However, current state of the art Heat-Air-Moisture (HAM) models that are used to assess the moisture behaviour of building facades are still based on several simplifications. Important phenomena of WDR such as raindrop impact, ...
From runoff contributor to runoff absorber: Spate irrigation on exclosures in Tigray's semi-arid environment (Ethiopia) KU Leuven Ghent University
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 ...
Impact of draining hilly lands on runoff and on-site erosion: a case study from humid Ethiopia Ghent University KU Leuven
The impact of land use on surface runoff generating processes in a Mediterranean mountainous basin Ghent University
Effects of precipitation and soil moisture behaviour in runoff generating processes were studied in a Mediterranean catchment subject to land use changes due to the abandonment of agriculture since the fifties. The Ribera Salada catchment is located in the Pre-Pyrenees mountainous area (NE Spain), in an altitudinal range between 420 - 2385 m. The substrate consists of massive conglomerates and calcareous sand and silt stones, with shallow soils, ...
Impact of draining hilly lands on runoff and on-site erosion: a case study from humid Ethiopia Vrije Universiteit Brussel
The use of drainage ditches on farmland has an impact on erosion processes both on-site and off-site, though their environmental impacts are not unequivocal. Here we study the runoff response and related rill erosion after installing drainage ditches and assess the effects of stone bunds in north Ethiopia. Three different land management systems were studied in 10 cropland catchments around Wanzaye during the rainy season of 2013: (1) the ...
Estimating the impacts of land-cover change on runoff using the soil and water assessment tool (SWAT): case study of Nzoia catchment, Kenya. WOK Vrije Universiteit Brussel
The SWAT model was used to investigate the impact of land-cover changes on the runoff of the River Nzoia catchment, Kenya. The model was calibrated against measured daily discharge, and land-cover changes were examined through classification of satellite images. Land-cover change scenarios were generated, namely the worst- and best-case scenarios. Historical land-cover change results showed that agricultural area increased from 39.6 to 64.3% ...
Does the effectiveness of soil and water conservation techniques in reducing runoff and soil loss change over time?: a case study from the semi-arid Ethiopian highlands Ghent University
Soil erosion by water is the most critical problem to be solved for a sustainable agricultural development in the north Ethiopian highlands. In Tigray region soil and water conservation (SWC) programs have started two decades ago under the umbrella of food for work program. Several studies were then conducted and these demonstrated that SWC reduces soil erosion. However the effectiveness and temporal evolution of the effectiveness of major SWC ...
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 ...
