Stormwater control measures, such as raingardens, tanks, or wetlands, are often employed to mitigate the deleterious effects of urban stormwater drainage on stream ecosystems. However, performance metrics for most commonly pollutant-load reduction, have not permitted prediction how they will change ecosystems downstream. Stream ecosystem responses more been predicted by catchment-scale measures...

Abstract The hydrological model calibration is a challenging task, especially in ungauged catchments. regionalization methods can be used to estimate the parameters of sub-catchments. In this article, sub-catchments calibrated by approach based on automatic clustering. Under clustering procedure, gauged and are grouped their physical characteristics similarity. optimal number clusters determine...

The scaling behaviour of landscape properties, including both morphological and landscape patchiness, is examined using monofractal and multifractal analysis. The study is confined to two neighbouring meso-scale catchments on the west coast of the South Island of New Zealand. The catchments offer a diverse but largely undisturbed landscape with population and development impacts being extremely...

Abstract The Mediterranean region is considered to be highly affected by climate change with rainfall deficits leading a significant decrease in river discharge. This study aims assess the impacts of on water resources catchment, namely Bas-Loukkos catchment (Morocco), where pressure already present due intensive hydro-agricultural development and likely increase. Mann–Kendall, Pettitt Buishand...

In most bucket-type hydrological models, water can only flow from the groundwater to stream and flux is based on storage. However, many catchments have losing sections, where streamflow recharges groundwater. We developed a formulation represent recharge by streamwater in model tested this for Panola Mountain Research Watershed demonstrate its function assess performance. The upper reach of cat...

Multiple stressors threaten stream physical and biological quality, including elevated nutrients and other contaminants, riparian and in-stream habitat degradation and altered natural flow regime. Unconventional oil and gas (UOG) development is one emerging stressor that spans the U.S. UOG development could alter stream sedimentation, riparian extent and composition, in-stream flow, and water q...

A wide range of nature-based solutions for flood hazard management work by storing and slowing flow within catchments, therefore, there is a need to identify the optimal locations implementing these solutions. This paper presents relative scoring-based mapping likely that contribute peak. Targeting reduction attenuating mitigation actions in can be an effective way reduce damages at impact poin...

Nitrate monitoring is commonly conducted with low-spatial resolution, only at the outlet or a small number of selected locations. As result, information about spatial variations in nitrate export and its drivers scarce. In this study, we present results high-spatial resolution between 2012 2017 65 sub-catchments an Alpine mesoscale river catchment characterized by land-use gradient. We combined...

A distributed hydrological model was applied to a 69 km2 experimental catchment, Eddleston Water, Scotland, UK. The impact on outputs of applying progressively simpler representations spatial variability in land use and superficial geology assessed. Alternative the distribution produced differences outputs. These were generally small with exception maximum absolute error (Emax). Inter-model mos...
