Deriving relationships between catchment-scale hydrologic response and landscape attributes allows the hydrologic response of an ungauged catchment to be predicted from its landscape attributes and climate. In this study, a lumped conceptual rainfall-runoff model was applied at a daily timestep to 16 small (less than 1 km) catchments in the Maroondah region of Victoria, Australia. The six param...

Water conservation becomes essential as the resource scarcer. The most important step in managing water resources is estimating watershed runoff generated from rainfall, and rainfall are key factors determining availability for surface storage groundwater recharge. So, this study mainly focused on three sub-catchments of Karamadai, Tamil Nadu, India, using heavy to extreme daily events received...

• Future climate and hydrological variables were simulated at a high resolution. The components of two mesoscale Alpine catchments explored. Snowmelt drives future streamflow changes elevations. Liquid rainfall influences lower Changes to means extremes are elevation season dependent. Mountainous cover broad range elevations their response warming is expected vary significantly in space. Nevert...

Abstract The results of an integrated study aimed at restoring water quality in a large watershed including seven catchments in north east Iran are presented in this paper. This case study demonstrates how landscape metrics reflect direct or surrogate causes of the land use practices that are the determinants of water quality parameters. Water quality factors included EC, pH, Cl-1, HCO3-1, SO4-...

This study focused on the Upper Manyame sub-catchment which covers an area of approximately 3 786 km2 and forms part catchment, one seven catchments Zimbabwe. catchment has its source in Marondera town drains into Zambezi River downstream Kariba Dam upstream Cahora Bassa Dam, northern country. assessed potential climate change impacts streamflow reservoir inflows sub-catchment. Hydrologic simul...

Mass balance studies in forested catchments in the northeastern USA show that S losses via streamwater SO4 exceed measured atmospheric S inputs. Possible sources of the excess S loss include underestimated dry deposition, mineralization of organic S in soils, desorption of soil sulphate, oxidation of recently formed sulphides and mineral weathering. Evaluating the relative contribution of these...

Climate change scenarios for northern boreal regions indicate that there will be increasing temperature and precipitation, and the changes are expected to be larger in winter than in summer. These precipitation and discharge patterns, coupled with shorter ice cover/soil frost periods in the future would be expected to contribute significantly to changing flow paths of organic matter over a rang...

Tracer-aided hydrological models are increasingly used to reveal fundamentals of runoff generation processes and water travel times in catchments. Modelling studies integrating stable water isotopes as tracers are mostly based in temperate and warm climates, leaving catchments with strong snow influences underrepresented in the literature. Such catchments are challenging, as the isotopic tracer...

Within the Swedish Monitoring Programme for Agriculture, 27 small agricultural catchments were investigated for between 9 and 14 years (6 years for one catchment), starting in the late 1980s, to determine the impact of agricultural activities on discharge water. The catchments represent major variations in climate, soil types and farming in Sweden and hence long-term average load of total nitro...
