Modelling the hydrological impacts of rural land use change
The potential role of rural land use in mitigating flood risk and protecting water supplies continues to be of great interest to regulators and planners. The ability of hydrologists to quantify the impact of rural land use change on the water cycle is however limited and we are not able to provide consistently reliable evidence to support planning and policy decisions. This shortcoming stems ...

Evaluation of the effect of land use/cover change on flood characteristics using an integrated approach coupling land and flood analysis
Land use/cover change (LUCC) is one of the crucial factors influencing the hydrological process, thus the flood characteristics in time and space. Therefore the evaluation of the change of flood characteristics implies an integrated analysis of LUCC and hydraulic simulation. In this study, the effect of LUCC on flood is examined based on an approach composed of three parts: (1) reproduction ...

Modelling design flood hydrographs in catchments with mixed urban and rural land cover
The effect of urban land cover on catchment flood response is evaluated using a lumped rainfall–runoff model to analyse flood events from selected UK catchments with mixed urban and rural land use. The present study proposes and evaluates a series of three extensions to an existing model to enable a better representation of urban effects, namely: an increase in runoff volume, reduced ...

Risk-based zoning for urbanizing floodplains
Urban floodplain development brings economic benefits and enhanced flood risks. Rapidly growing cities must often balance the economic benefits and increased risks of floodplain settlement. Planning can provide multiple flood mitigation and environmental benefits by combining traditional structural measures such as levees, increasingly popular landscape and design features (green ...

With a stormy future ahead, study offers new tools for managing runoff
These two words might make you sleepy: stormwater management. But they should make you scared. Or, if a new study can help shake things up, hopeful. Runoff carrying oil, salt, fertilizer, sediment and other pollutants is a top threat to lakes across the U.S., and several factors — including rising population, growing cities and changing climate — are loading the future’s dice ...

Reconstructing the polder: negotiating property rights and 'blue' functions for land
Dikes were the core of Dutch river flood protection. Near-floods in 1993 and 1995 and debates about climate change, however, led to a rethinking of existing approaches. In the policy directive 'Room for the River' the focus has shifted from infrastructure (dikes) to spatial measures (bypasses, dike relocations, 'green' rivers). While people and land used to be separated from water by dikes, this ...

Large-scale flooding analysis in the suburbs of Tokyo Metropolis caused by levee breach of the Tone River using a 2D hydrodynamic model
In order to assess the effects of climate change on flood disasters in urban areas, we applied a two dimensional finite element hydrodynamic model (2D-FEM) to simulate flood processes for the case analysis of levee breach caused by Kathleen Typhoon on 16 September 1947 in Kurihashi reach of Tone River, upstream of Tokyo area. The purpose is to use the model to simulate flood inundation processes ...

Subsidence of peat soils in South-East Asia – Flooding risks in Sarawak
There is an increase in awareness of the carbon emissions resulting from peatland drainage and peat fires. There is in general however a lack of recognition of the link between carbon loss and peatland subsidence, i.e. lowering of the soil surface. This paper presents the case study of the Rajang Delta in Sarawak, Malaysia where peatland subsidence will cause flooding, rendering 50% and 67% of ...

Water resources in Europe in the context of vulnerability
Water plays a central role in the functioning of the biosphere and in supporting all life. Freshwater ecosystems are particularly important, providing a unique and diverse array of services upon which human society depends. These services include 'provisioning' services, such as the provision of water for agriculture and hydropower. They also include 'regulating' services, where water helps ...
