Abstract:
... Sediment connectivity is the capability of a system to regulate the exchange of sediment in catchments. The Index of Connectivity (IC) has become a widely used tool, offering a practical way to assess sediment connectivity from hillslopes to downstream channels. We present a novel implementation of IC in R environment to expand the audience of users and encourage alternative applications of the in ...

Abstract:
... An analytical model is developed using the homotopy perturbation (HP) method for predicting explicitly the location of water table heights resulting from steady drainage of a homogeneous sloping aquifer overlying a uniformly sloping impervious barrier at a finite distance from the top of the soil. The model assumes the aquifer to receive a steady recharge at its surface, the drains to have equal w ...

Multiplication of monoecious hemp varieties requires manual male plants rouging to keep a high share of monoecious plants in the population. It forces relatively small multiplication fields usually oscillating around 5 ha, where the use of big harvesting machines is ...

Abstract:
... Spatially integrated transport models have been applied widely to model hydrologic transport. However, we lack simple and process‐based theoretical tools to predict the transport closures—transit time distributions (TTDs) and StorAge Selection (SAS) functions. This limits our ability to infer characteristics of hydrologic systems from tracer observations and to make first‐order estimates of SAS fu ...

How sediment concentration in upslope inflow influences downslope EG erosion is still unclear. Thus, field monitoring on a natural hillslope and indoor simulations on a dual-box system were conducted to better unde ...
