Our models have assumed homogenous soil and crop components, meaning that state variables depend only on time and do not vary over space. However, one may need to explicitly incorporate spatial variability of soil state variables. An example is presented here in which soil water content (and ...

Although the former has clear physical meaning, it is more computationally intensive, while the latter is relatively easy to calculate and can correct the statistical bias of the GCMs with better results, so it is widely used in research regarding the impact of climate change at the regional ...
The novel approach provides a clear physical meaning for S, allowing better estimation of this parameter in humid shallow water table environments where the variable source area can be the dominant runoff mechanism.Mahmood H.

When examining the proportion of the catchment that is occupied by urbanization classes, that is, CPD (Falcone, 2011; Miller & Hess, 2017), this proportion varied between 0% and 100%, with a median value of 29%, meaning that the range of TIA used here covered a large variety of ...
water models are typically used for the simulation of relatively short flooding events of some hours up to a few days rather than long-term rainfall–runoff simulations, infiltration represents the most important water loss [16], while evapotranspiration can be neglected in many cases or taken ...
Therefore, it has significant meaning to develop on-line equipments to measure slope runoff and sediment concentration accurately and synchronously. In order to resolve this problem, an automatic testing device for detection of runoff rate and sediment concentration was designed based on time method ...
From the viewpoint of the interaction between rain and vertical building facades however, the term “WDR intensity” takes on the narrower meaning of “component of the rain vector causing Wind-driven rain impingement patterns and the wind-blocking effect Knowledge of WDR impingement patterns on ...
The understanding of the physical meaning of these parameters, their relative influence, and of the differences between the abovementioned methods is important for students. Infiltration measurements in the field or lab are time-consuming. We therefore developed a tool that helps the students to ...
