Quantification of climate change impacts on urban catchment hydrology and water sensitive design devices
Urban catchments and waterways play a vital role in the development of cities. However, climate change is projected to adversely affect the urban catchment hydrology. Thus, future projections of climatic variables are needed at high temporal and spatial resolutions for stormwater impact assessment …

Susceptibility Of Headwater Catchment Hydrology To Persistent Droughts And Forest Structure Modification - A Plot To Catchment Scale Analysis
Headwater catchments across the Western United States are critical environments to natural ecosystems and are a vital component of water resources to many communities and industries and may be strongly affected by changing climate and altered disturbance regimes. To better quantify how these …

An Analysis of Hydrological Model Uncertainty at the Local Stage of a Climate Change Impact Assessment in the Suir Catchment
… due to GCMs and emissions scenarios. The Suir catchment is employed as a case study area to analyse the changes in catchment hydrology and in future flood magnitude and frequency relationships due to climate change. Two lumped conceptual rainfall-runoff models of different degrees of complexity …

Determining primary drivers of river bead functionality in mountain headwater streams
… magnitudes. Geomorphic driver variables include catchment and reach-scale geometry and catchment hydrology, which approximate water inputs into the stream corridor, as well as delta normalized burn index (dNBR) and catchment slope, which approximate sediment inputs into the stream corridor. …

Drainage Timescale Estimates and Storage Change Analysis on A Basin Scale
… time depicts the characteristic timescale of the catchment drainage process and is therefore also known as drainage timescale (K). Catchment drainage timescale can be estimated empirically from recession flow analysis as well as from hydraulic theory. Applicability of is critical in groundwater …

Hydrologic modeling using triangulated irregular networks : terrain representation, flood forecasting and catchment response
… surface and subsurface processes leading to the catchment response. As a research tool for hydrologic forecasting and experimentation, the TIN-based Real-time Integrated Basin Simulator (tRIBS) fully incorporates spatial heterogeneities in basin topography, surface descriptors and …

The development of a methodology for the identification of potential wet grassland restoration sites in south west England
… grassland location and the landscape topography, catchment hydrology and soil physical characteristics, with the use of Geographical Information Systems. Landscape topography was expressed as the ln(a/tan^) topographic index, in which 'a' is the upslope area draining through the point for which …

Natural flood management - an Ecosystem based Adaptation response for climate change
… delivery of ecosystem services. Tarland Burn catchment (NE Scotland) was used as a platform to explore individual adaptation options through woodland expansion (distinguishing between coniferous and deciduous) and drainage schemes, together with land use scenarios that explore emergent …

Simulation of catchment runoff, erosion and sediment transport using a transient numerical model for Mlalazi catchment
Catchments and estuaries are fragile systems that are prone to serious degradation from many different anthropogenic impacts. Much research has been conducted on developing an understanding of the fluvial processes in river catchments and in estuary dynamics. Many of the anthropogenic impacts on …

Are all wetland models the same? Comparing wetland models and streamflow regulation of catchment-scale hydrological modelling tools under a changing climate
… characteristics, processes and impacts on catchment streamflow in different modelling tools and models (i.e. setups in a tool). Evaluating wetland models supports wetland-inclusive modelling and ensures that a wetland model is hydrologically sound and suitable. An unchannelled valley-bottom …

A multifaceted analysis of diurnal streamflow patterns through the application of advanced analytical tools
… the complex dynamics of water flow within a catchment is fundamental to effective water resource management. This understanding involves robust knowledge of the catchment's hydrological and physiographical features. It requires a profound grasp of the spatiotemporal variability in a …

Improved understanding and prediction of the hydrologic response of highly urbanized catchments through development of the Illinois urban hydrologic model (IUHM)
What happens to the rain in highly urbanized catchments? That is the question that urban hydrologists must ask themselves when trying to integrate the hydrologic and hydraulic processes that affect the hydrologic response of urban catchments. The Illinois Urban Hydrologic Model (IUHM) has been …

INTEGRATED WATER RESOURCES ASSESSMENT AND MANAGEMENT IN A DROUGHT-PRONE WATERSHED IN THE ETHIOPIAN HIGHLANDS
… one season. A second study measured plot and catchment hydrologic responses with and without conservation measures. Results show that severe erosion in the watershed occurred during few erratic storms rather than steadily across all seasons. Gently-sloped cropland generated over twice the …

Application of GIS and Remote Sensing techniques to evaluate the impact of land cover and land use changes on the hydrology and water resources of Luvuvhu River Catchment in Limpopo Province, South Africa.
Luvuvhu River Catchment (LRC) exhibits diverse land use and land cover patterns that are influenced by seasonality and socio-cultural practices of the local communities. From 1950, the catchment has been undergoing land cover changes caused by expanding villages, new urban centres and clearing …
