“…They serve as storage or sedimentation tanks for stormwater management [1][2][3][4][5], and are part of green infrastructures such as constructed wetlands [6][7][8][9]. They are also used as settling basins in irrigation networks [10,11] and for the treatment of waste water [12] or drinking water [13]. Shallow reservoirs serve as storage facility, in the form of service reservoirs in water supply systems [14], or as ancillary structures of hydropower schemes [15].…”

“…For instance, the efficiency of sediment trapping in stormwater reservoirs has a considerable influence on the quality of water reaching the receiving body [6,21]. Predicting the pattern of sediment deposits is of practical relevance for planning maintenance operations [12]. Similarly, water quality in drinking water reservoirs depends on water residence time and degree of mixing [14,22].…”

Shallow reservoirs are hydraulic structures widely used for water storage or as sedimentation tanks. Their design and sizing are intricate due to the complex flow fields developing in such structures, hence suitable indicators are needed to evaluate their hydraulic performance. Based on the outcomes of a depth-averaged computational model, we analysed the potential of the distribution function of the volume-averaged water age to unveil in a concise way valuable information on the flow field in rectangular shallow reservoirs. Ten different reservoir layouts were examined. In all cases, the shape of the computed distribution function reveals a remarkable amount of information on the flow field in the reservoirs. The distribution functions exhibit a sequence of steps, followed by an exponential decay, which may be related to fast and slow pathways travelled by water particles along their routes across the reservoirs. As such, the distribution function of the volume-averaged water age was found to provide valuable information for assessing the hydraulic performance of shallow reservoirs, while achieving an effective reduction in the problem dimensionality.

The study investigated the structure of the integrated solar and hydraulic jump enhanced waste stabilization pond (ISHJEWSP) variables. Also, to determine the cluster of the most important variables that account for the performance of the ISHJEWSP using principal component analysis (PCA). Three sets of experimental ponds were constructed with varying locations of point of initiation of hydraulic jump. Wastewater samples collected from the inlet and outlet for varying inlet velocities were examined for physicochemical and bacteriological characteristics for a period of nine months. The Pearson’s R-matrix and KMO statistic were used in evaluating the structure of the variables. Consequently, the variables of temperature, pH, algae concentration, solar radiation, and locations of the point of initiation of hydraulic jump were subjected to PCA. Two components had eigenvalues above the Jolliffe’s criterion and in combination explained 90.66% of the total variance. The inflexion of the scree plot justified the retained components. The analysis after rotation revealed that the parameters of pH, temperature, solar radiation, and algal concentration loaded highly to component 1. This underscores the precedence of ambient climatic conditions, alongside the state of the wastewater in general, to the inlet velocity and location of point of initiation of hydraulic jump.
