The catchment, or catchment area, is the area associated with a segment of a drainage network. Surface runoff in a catchment flows into the associated network segment. Catchment area is commonly used for estimating watershed parameters, such as upstream drainage area, flood frequency, or surface-water flow. Hydrologic analyses require relatively accurate catchment area estimates to furnish subs...

Abstract. Rainfall is known as the main water replenishment in dryland ecosystems, and rainfall partitioning by vegetation reshapes spatial temporal distribution patterns of rainwater entry into soil. The dynamics have been extensively studied at inter-event scale, yet very few studies explored its finer intra-event relating driving factors for shrubs. Here, we conducted a concurrent in-depth i...

the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...

The development of catchment modelling tools has gained considerable momentum through the Cooperative Research Centre for Catchment Hydrology’s Catchment Modelling Toolkit. This repository of models (see www.toolkit.net.au) allows the modeller to select the most appropriate tools with which to best represent their catchment and associated constituent processes. While this has improved the abili...

Water quality data, collected by the Environment Agency in England and Wales over 10 years (1991 – 2000) were used to examine the spatial distribution of nutrient pollution risk and for assessing broad-scale spatial and temporal variability in nutrient fluxes across the Wye catchment. Nutrient water quality across the upper and middle Wye catchment, and along the main River Wye, is generally ve...

Pangyo experimental catchment is located in Unjung Stream, which is the second tributary of the Tan River, the first tributary of the Han River, as well as Geumto Stream, which is a tributary of Unjung Stream. The area of the entire catchment is 23.1 km, with the Geumto Stream catchment spanning 9.84 km and the Unjung Stream catchment 13.26 km. Four ultrasonic stream gauges, one water level gau...

A new approach to regionalisation for prediction of flow characteristics in ungauged catchments is presented. If flows in ungauged catchments are to be predicted using calibrated rainfall-runoff models, regional relationships between the parameters of such models and catchment attributes must be determined. This is only possible with parsimonious models (fewer than about 7 parameters), and even...
