The complex interactions and feedbacks between humans and water are critically important issues but remain poorly understood in the newly proposed discipline of sociohydrology (Sivapalan et al., 2012). An exploratory model with the appropriate level of simplification can be valuable for improving our understanding of the co-evolution and self-organization of socio-hydrological systems driven by...

Interactions between humans and the environment are occurring on a scale that has never previously been seen; the scale of human interaction with the water cycle, along with the coupling present between social and hydrological systems, means that decisions that impact water also impact people. Models are often used to assist in decision-making regarding hydrological systems, and so in order for...

Hydrological time series forecasting remains a difficult task due to its complicated nonlinear, non-stationary and multi-scale characteristics. To solve this difficulty and improve the prediction accuracy, a novel four-stage hybrid model is proposed for hydrological time series forecasting based on the principle of 'denoising, decomposition and ensemble'. The proposed model has four stages, i.e...

Simulation of flow hydrograph at an ungauged site recently has attracted considerable attention. A distributed rainfall-runoff model not only can describe the spatial heterogeneity of physiographical and hydrological characteristics in the catchment, but also can simulate the hydrological processes inside the studied area. If a distributed rainfall-runoff model can be adequately verified based ...

A major research challenge in ungauged basins is to quickly assess the dominant hydrological processes of watersheds. In this paper we present a top-down approach from first field reconnaissance to perceptual model development, model conceptualization, evaluation, rejection and eventually, to a more substantial field campaign to build upon the initial modeling. This approach led us from an init...

In the past, water resources in Australia have been over-allocated and this has led to the implementation of water reforms. An integrated assessment project is underway in the Namoi Catchment, located in New South Wales, Australia, that aims to assess the social, economic and ecological impacts of reductions in water allocations under current and future environmental conditions. Surface and gro...

Hydrological model development and application for research projects is most often a cycle of model selection, model application, model adaptation and enhancement. The reason for the adaptation of an existing one or the development of a new model is that most of the conceptual hydrological models have been developed for a specific test catchment, scale and problem focus. The transfer to other c...
