E-mail: [email protected] Forest roads are an important environmental issue. While many scientists interested in hydrology recognize climate-altering processes as an important global issue, there are problems that are similar in scope and magnitude because ...

This paper addresses the impact of the source and processing method of land use information for hydrological simulations on the long-term water balance of the Yzeron peri-urban catchment (150 km), located near Lyon, France. A customised version of the distributed hydrological model J2000 was used to perform simulations at a daily time step. Five land use data sets obtained from aerial photograp...

We analyzed Landsat MSS and ETM+ images to detect 25-year land-cover change (1976-2001) in the critical Taguibo Watershed in Mindanao Island, Southern Philippines. This watershed has experienced historical modifications of its land-cover due to the presence of logging industries in the 1960s, and continuous deforestation due to illegal logging and slash-and-burn agriculture in the present time....

While tropical montane cloud forests (TMCF) provide critical hydrological services to downstream regions throughout much of the humid tropics, catchment hydrology and impacts associated with forest conversion in these ecosystems remain poorly understood. Here, we compare the annual, seasonal and event-scale streamflow patterns and runoff generation processes of three neighbouring headwater catc...

Runoff constitutes one of the major water losses from agricultural fields in semi-arid areas. However, by adopting appropriate soil management practices, the runoff can be harnessed for improving crop yields. The main objective of this study was to quantify rainfall-runoff relationships under in-field rainwater harvesting (IRWH) using simulated rainfall, and to compare these results to those ob...

This paper presents a distributed model that is in operational use for forecasting flash floods in northern Austria. The main challenge in developing the model was parameter identification which was addressed by a modelling strategy that involved a model structure defined at the model element scale and multi-source model identification. The model represents runoff generation on a grid basis and...

Real time forecasts of the snowmelt runoff up to six days in advance were carried out for basins in the Alps of the Zillertal, Austria, which are part of a network of reservoirs for hydropower generation. The forecasts are based on the Snowmelt Runoff Model (SRM). Input data to SRM are taken from online measurements of hydro-meteorological parameters, from numerical weather forecast models, and...

The spatial distribution of water storage capacity has always been the critical content study saturation-excess runoff. Xin’anjiang model uses curve (WSCC) to characterize for runoff yield calculation. However, mathematical and physical foundations WSCC are unclear, which is impossible simulate generation with complex basins accurately. To fill this gap, we considered dominant role basin charac...

abstract flood is among phenomena which result considerable damages to resources and is a serious issue among hydrologists. the proper estimation of runoff is necessary for designating appropriate approaches for its control or optimal management. various problems have been reported in application of empirical models. the regional analysis of runoff with different return periods by applying wate...

Theoretically derived distributions allow the detection of dominant runoff generation mechanisms as key signatures of hydrologic similarity. We used two theoretically derived distributions of flood peak annual maxima: the first is the ―IF‖ distribution, which exploits the variable source area concept, coupled with a runoff threshold having scaling properties; the second is the Two Component-IF ...
