The goodness of fit is estimated using the coefficient of determination R2. In particular, the explanatory power of ASM across all the classes of TIA R2 (RR, ASM) is computed as (2)where MRRi,j is the element (i, j) of matrix MRR (Equation 1), are estimations from the regression...
Different model parameters exist in each type of model: runoff coefficient (or loss) parameters and lag time (or time to peak) parameters in the case of event models; and evaporation parameters, runoff generation parameters and storage coefficients in the case of ESMA models. The procedures for...
Throughflow in time depends on the instantaneous difference of sea and lagoon elevations, the wetted cross section, a function of seaward head, the angle of feasible oscillations of the hinged gates, and a discharge coefficient. The mean lagoon rise Δh can be given as a function of the ...
The routing of runoff from different cells to the watershed outlet depends on flow velocity and the wave-damping coefficient using the method of diffusive wave approximation. The detailed calculation formulas are shown in [57]. The improved Wetspa model is a distributed physical hydrological model ...
26]. Through a global sensitivity analysis, the 10 most representative parameters were then selected. After 7400 iterations, the sensitivity analysis of SWAT model parameters for the PLB was completed (Table 2). The applicability of the SWAT model was evaluated using the fitting coefficient R2and ...
(2) Qualitative analysis methods such as the MK test, wavelet analysis, RS analysis, and spatial interpolation were used to reveal the spatiotemporal evolution of annual and seasonal runoff. (3) The Pearson correlation coefficient method and cumulative slope comparison method were used to explore ...
The water phase of the hydrological cycle is defined as the process of routing runoff in a river channel using the variable storage coefficient method. A detailed description of the model can be also found in Neitsch et al. [46]. SWAT is also able to simulate evapotranspiration, infiltration,...
where 𝑣𝑠vs is overland flow velocity; 𝑎a is the multiplier on overland Manning’s roughness; 𝑛𝑠ns is overland Manning’s roughness coefficient; 𝑆𝑠Ss is the average overland slopes. 2.2.2. Interflow and Groundwater Routing The linear reservoir method in the Xin’anjiang model...
However, the role of wind stress in mixing and transport processes should not be neglected [1]. The impact of freshwater runoff, as one of the main forcing factors governing the salinity patterns in coastal lagoons, has been widely studied for several coastal lagoons worldwide. Examples include...
