Catchment hillslopes in nature have a complex geometry. Complex hillslopes have different
plans (convergent, parallel and divergent) and different curvature (straight, concave and …

Determining the catchment design peak flow is crucial in hydrological practice. In this paper,
the conceptual rainfall–runoff model EBA4SUB (Event-Based Approach for Small and …

Hydrological cycle research requires a detailed analysis of the involved parameters to
understand watershed behavior comprehensively. In recent decades, both Geographic …

Dividing a catchment to subcatchment or hillslope scales allows for better scrutiny of the
changes in spatial distribution of rainfall, soil attributes and plant cover across the …

Rainfall–runoff modelling has always been of great importance in hydrology. Recently, the
Event-Based Approach for Small and Ungauged Basins (EBA4SUB) model, based on the …

For many permeable catchments with proper plant cover, subsurface flows play a key role in
generating surface runoff. In this regard, developing subsurface flow models is of great …

Flash flood disaster ranks top among all the natural hazards across the world due to its high
frequency, severity and fatality. However, flash flood simulation is still challenging in small …

The geomorphologic instantaneous unit hydrograph (GIUH) is an applicable approach that
simulates the runoff for the ungauged basins. The nash model is an efficient tool to derive …

Separating surface flow (SF) from subsurface flow (SSF) based on direct runoff
measurements in river gauges is an important issue in hydrology. In this study, we …

Estimation of rainfall-runoff model parameters in ungauged catchments is of significant
importance. The Nash geomorphological instantaneous unit hydrograph (NGIUH) model is …
