The uncertainties arising from the problem of identifying a representative model structure and model parameters in a conceptual rainfall-runoff model were investigated. A conceptual model, the HBV model, was applied to the mountainous Brugga basin (39.9 km") in the Black Forest, southwestern Germany. In a first step, a Monte Carlo procedure with randomly(More)
[1] A key component to understanding and predicting water fluxes and water quality in river basins is the spatial distribution of water-saturated areas. There is limited knowledge on spatial patterns of saturated areas, their relation to landscape characteristics and processes, and the ability of hydrological models to represent the observed spatial(More)
Hydrological and geomorphological processes are key to mangrove forest growth and development. However, few mangrove hydrology studies exist in Central America. A 0.2 km2 mangrove forest on the Pacific coast of Nicaragua was investigated to determine the water balance dynamics during the dry season. The used multi-methods approach combined hydrology,(More)
For optimal protection and integrated management of water resources, it is essential to quantify the impact of land-use change on hydrological regimes at various scales. Using the process-based catchment model TAC D (tracer aided catchment model, distributed) two land-use scenarios were analysed for the rural and mountainous Dreisam basin (258 km 2): (i) an(More)
Groundwater is the most important resource for local society and the ecosystem in the semi-arid Hailiutu River catchment. The catchment water balance was analyzed by considering vegetation types with the Normalized Difference Vegetation Index (NDVI), determining evapotranspiration rates by combining sap flow measurements and NDVI values, recorded(More)

Daily gridded rainfall data over Peninsular Malaysia are delineated using an objective clustering algorithm, with the objective of classifying rainfall grids into groups of homogeneous regions based on the similarity of the rainfall annual cycles. It has been demonstrated that Peninsular Malaysia can be statistically delineated into eight distinct rainfall(More)
