“…Under flood water depths of 1, 3, 5 and 10 cm, the groundwater Similar results were reported by Sorman and Abdulrazzak [24], who suggested that flood runoff volume and duration were the dominant factors influencing the cumulative infiltrated volume and recharge of shallow groundwater tables. Morin et al [1] showed the importance of the role of large and medium floods in aquifer recharge; the relative contribution of high-magnitude floods to groundwater recharge also increased, whereas medium and small floods contributed relatively less.…”

“…These results indicated that the height of the water table rise was closely related to flood water depth; if the initial water table was deeper, the variation in the depth of the water table rise was smaller. Sorman and Abdulrazzak [24] also reported that the relationship between the ground water recharge and flood inflow volume could be represented by linear regression equations, with the correlation coefficients of 0.76, but the slope was 0.302, which was still lower than the slope related to flood recharge infiltration in our research. Note that Sorman and Abdulrazzak [24] experiments were conducted under conditions of possible surface water runoff, while our experiments were conducted in lysimeters with ponding water, with no occurrence of outflow.…”

Floods are of great concern as the global climate changes, and investigations of flood water infiltration and groundwater recharge are important for water resource management worldwide, especially under conditions of global climate changes. However, information on the relationship between the flood water and groundwater recharge is limited. The objective of this study was to determine the relationship between the flood water depth and the height of groundwater rise using lysimeters and numerical modeling in the floodplain of the Tarim River in northwestern China. The experimental results suggested that the rise in height of the groundwater table was closely related to the flood water ponding depth, and the groundwater depth decreased quickly after flooding due to the high infiltration rate of water originating at the Tarim River. The water table falling velocity was significantly less than the water table rising velocity. If the initial groundwater table was deeper, the variation in the water table rise depth was smaller and the water table falling velocity was slower. The numerical simulation results showed good agreement with the observed data, with a determination coefficient (R 2 ) of 0.87 and a root mean square error (RMSE) of 63.91 cm. A good relationship (R 2 = 0.789) between the initial groundwater table depth (H 0 ), initial soil water content (W 0 ), flood water depth (h), and height of the water table rise (H) was established. Considering that natural and artificial flood frequencies are related to flood time interval (dt), a relationship (R 2 = 0.892) was developed between them. These results can enhance the understanding of flood recharge characteristics in the floodplains of inland rivers.

“…Several regression equations were presented to estimate the transmission losses and recharge from a wadi-bed in Saudi Arabia [6,17]. These studies indicate that the magnitude of transmission losses and consequent recharge resulting from given upstream runoff hydrographs is a function of stream and sediment characteristics.…”

Transmission losses (TL) are complicated phenomena that characterize the processes of evapotranspiration and infiltration as water moves down a stream. This analysis focuses on transmission losses that occur within the stream and can be computed with data from tandem stream gauges. Data from Walnut Gulch Experimental Watershed (WGEW), in southeast Arizona, are the primary source. The WGEW is a typical watershed in the region where a network of alluviumfilled stream represents a range of widths and slopes. TL results were compared with those from other U.S. streams as reported in several published papers. TL per kilometer (TL/km) were calculated by dividing the difference between flow volumes at the upstream and downstream gages by the distance between gages. Only storms that occurred above the upstream gage were considered. TL/km for several storms and stream reaches were plotted against the inflow volume and peak inflow discharge and a consistent pattern emerged. These plots yielded parameterized equations that were used to compare published TL for Queen Creek, AZ and several Plains States streams. The sediment characteristics of the streams were also incorporated into the model by using their hydraulic conductivity. The objective of this study was to develop a simple, rapid method requiring only a minimum of pre-existing data to determine transmission losses in ephemeral streams in arid climates that can be used easily by regulators and planners. Furthermore, the models can contribute to the determination of "significant nexus" of the US Clean Water Act (CWA), Section 404 jurisdiction.

Wadi aquifers in Saudi Arabia historically have been recharged primarily by channel loss (infiltration) during floods. Historically, seasonal groundwater levels fluctuated from land surface to about 3 m below the surface. Agricultural irrigation pumping has lowered the water table up to 35 m below the surface. The geology surrounding the fluvial system at Wadi Qidayd consists of pelitic Precambrian rocks that contribute sediments ranging in size from mud to boulders to the alluvium. Sediments within the wadi channel consist of fining upward, downstream-dipping beds, causing channel floodwaters to pass through several sediment sequences, including several mud layers, before it can reach the water table. Investigation of the wadi aquifer using field observation, geological characterization, water-level monitoring, geophysical profiles, and a hypothetical model suggests a critical water level has been reached that affects the recharge of the aquifer. The wetted front can no longer reach the water table due to the water uptake in the wetting process, downstream deflection by the clay layers, and re-emergence of water at the surface with subsequent direct and diffusive evaporative loss, and likely uptake by deep-rooted acacia trees. In many areas of the wadi system, recharge can now occur only along the channel perimeter via fractured rocks that are in direct horizontal hydraulic connection to the permeable beds above and below the water table.
