Space-Time Uncertainty Propagation Of Input Precipitation Across A Coupled Rainfall-Runoff Urban Drainage Model, Arturo Torres-Matallana, Ulrich Leopold
Space-Time Uncertainty Propagation Of Input Precipitation Across A Coupled Rainfall-Runoff Urban Drainage Model, Arturo Torres-Matallana, Ulrich Leopold
International Congress on Environmental Modelling and Software
Rainfall is one important source of uncertainty in the simulation of combined sewer overflows and the emissions of pollutants to the receiving water body. Studies often ignore the spatial dimension treating input rainfall as a non-spatially distributed time series. Neglecting spatial and space-time distribution of rainfall entering urban drainage systems may result in inaccurate quantification of rainfall and, hence, in substantial uncertainties associated to water quantity and quality predictions. We developed a space-time interpolation model for rainfall, based on space-time Kriging, using point rainfall measurements as the primary variable. We then interpolated rainfall over space and time and built a …

Spatial Uncertainty Propagation In Ecosystem Service Assessment Modelling Under Change Of Scale, Ulrich Leopold, Benoit Othoniel, Benedetto Rugani
International Congress on Environmental Modelling and Software
Ecosystem Service models are increasingly getting attention in current and future natural resource management and evaluation. Due to combinations of different submodels from various disciplines they belong to the family of integrated environmental assessment models. These models are often complex modelling chains with submodels developed and operating at different scales. Uncertainties associated to model predictions due to change of scales or support play a major role when different scenarios are tested for decision and policy making. This paper studies the impacts of land use and land cover change under spatial uncertainty on ecosystem services such as pollination, focussing on urban …
