This study aims to address the gap in Natural Flood Management (NFM) evidence base concerning its implementation potential groundwater-dominated catchments. We generated a typology of 198 chalk catchments using redundancy analysis and hierarchical clustering. Three catchment typologies were identified: (1) large catchments, (2) headwater with permeable soils, (3) impermeable soils surfaces (urb...

Abrupt runoff reduction in the Wei River Basin (WRB) has attracted extensive attention owing to climate change and human activities. Nevertheless, previous studies have inadequately assessed respective contributions of variability activities on different spatial scales. Using Mann–Kendall Pettitt’s methods, this study identified long-term (1970–2018) changes hydro-meteorological variables. Furt...

Low flows can impact water use and instream ecology. Therefore, reliable predictions of low-flow metrics are crucial. In this study, we assess which catchment characteristics (climate, topography, geology landcover) explain the spatial variability at two different scales: regional scale small headwater scale. For regional-scale analysis, calculated mean 7-day annual minimum flow (qmin), that is...

This contribution determines suitable fingerprinting properties for sediment source discrimination within theAmrovan and Atary catchments in Semnan Province, Iran. These catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

In this study lake levels of Lake Tana are simulated at daily time step by solving the water balance for all inflow and outflow processes. Since nearly 62% of the Lake Tana basin area is ungauged a regionalisation procedure is applied to estimate lake inflows from ungauged catchments. The procedure combines automated multi-objective calibration of a simple conceptual model and multiple regressi...

This paper presents a comparison of the predictive capability three hydrological models, and mean ensemble these in heavily influenced catchment Peninsular India: GWAVA (Global Water AVailability Assessment) model, SWAT (Soil Assessment Tool) VIC (Variable Infiltration Capacity) model. The performance models their were investigated five sub-catchments upstream reaches Cauvery river catchment. M...

Areas of the Last Glaciation in northern Poland differ widely as to the conditions controlling the formation of river runoff and solute loads. The aim of the research was to identify chief mechanisms of stream alimentation in this area depending on the scale of a catchment. The analysis rested on data from hydrochemical profiling. Three types of systems were found to occur: in spring-head catch...
