Abstract:
... While modelling includes many detailed processes, the model setup gets costly. Delineating distributed parameters requires advanced GIS processing techniques and programming expertise, limiting models' usage to researchers and practitioners with sufficient resources. Although high-resolution input data get increasingly available, only a few preprocessing algorithms of integrated hydrological model ...

Abstract:
... Knowledge of design peak flow is crucial in various hydrology, hydraulics, and water resources management applications. However, obtaining design peak flow is challenging, especially in ungauged basins lacking discharge observations, a circumstance that does not allow the calibration of advanced hydrological models. Recently, a new method called EBA4SUB (event-based approach for small and ungauged ...

Abstract:
... Slope units (SUs) are sub-watersheds bounded by ridge and valley lines. A slope unit reflects the physical relationship between landslides and geomorphological features and is especially useful for landslide sensitivity modeling. There have been significant algorithmic advances in the automatic delineation of SUs. But the intrinsic difficulties of determining input parameters and correcting for un ...

We evaluated hydro-crop simulation of Malaysia’s largest rice granary using the Soil Water Assessment Tool (SWAT). The 4515 km² watershed is characterized by dams in the upper sub-watersheds that drain towards 1007 km² of ri ...

Abstract:
... Various sampling strategies come into operation to monitor water quality in rivers. Most frequently, grab samples are taken, but they are not suitable for recording the highly dynamic transport of solids and solid-bound pollutants. Composite samples reduce the influence of input and transport dynamics and are better suited to determine the annual river loads. Large-volume samplers (LVSs) produce b ...
