“…For storm floods, most studies focused on flood disasters and forecast [13,14], flood risk and efficiency [15,16], and floodwater utilization [17,18], which has been extended such that rain-flood can be one of the main recharge sources for groundwater in some regions [19,20]. Despite the disaster of floods, under positive circumstances, flood water can be used to constitute a considerable amount of a region's water resources [21], especially in a groundwater system.…”

Groundwater recharge from rainstorms can be vital for regional water resources. With the expansion of the need for more water in some specific regions under global climate change, groundwater is being pumped at a far greater rate than it can be naturally replenished. Considering that excess rainstorms could be utilized for groundwater recharge to lessen the declining tendency of regional groundwater level in the Sanjiang Plain, Northeast China, we analyzed groundwater changes in the quantity of a regional shallow aquifer in the region following extreme rainfall in 2013. The results show that shallow groundwater table in the north and central Sanjiang Plain increased following the 2013 extreme rainfall. Most of the annual maximal change of groundwater depth (MCGD) was in the range of 1 m to 3 m, occupying 72.1% of the study area. The average MCGD was 1.73 m in 2013, about 0.4 m higher than the mean value during the last five years (1.33 m). Spatially, the overall average groundwater depth showed an increasing trend from the southeast to the midwest and northeast. We estimated a total recharge of approximately 41.14 × 10 8 m 3 from the 2013 extreme rainfall across the north and central Sanjiang Plain. This large quantity of recharge demonstrates the important role that large rainstorms can play in regional shallow groundwater resources.

“…Naturally, flood mitigation is a highprofile ES (Barth, N.-C. and Döll, P. 2016;Opperman, J.J. et al 2017). Permeable floodplain deposits allow floodwater storage and the ability to mitigate floods (Lü, S.B. et al 2012).…”

Perspectives of land evaluation of floodplains under conditions of aridification based on the assessment of ecosystem services

Global climate change has discernible impacts on the quality of the landscapes of Hungary. Only a dynamic and spatially differentiated land evaluation methodology can properly reflect these changes. The provision level, rate oftransformation and spatial distribution of ecosystem services (ESs) are fundamental properties of landscapes and have to be integral parts of an up-to-date land evaluation. For agricultural land capability assessment soil fertility is a major supporting ES, directly associated with climate change through greenhouse gas emissions and carbon sequestration as regulationg services. Since for Hungary aridification is the most severe consequence of climate change, water-related ESs, such as water retention and storage on and below the surface as well as control of floods, water pollution and soil erosion, are of increasing importance. The productivity of agricultural crops is enhanced by more atmospheric CO2 but restricted by higher drought susceptibility. The value of floodplain landscapes, i.e. their agroecological, nature conservation, tourism (aesthetic) and other potentials, however, will be increasingly controlled by their water supply, which is characterized by hydrometeorological parameters. Case studies are presented for the estimation of the value of two water-related regulating ESs (water retention and groundwater recharge capacities) in the floodplains of the Kapos and Drava rivers, Southwest Hungary. It is predictable that in the future land evaluation techniques based on the FAO framework will be more dynamic and integrated with the monetary valuation of ESs. The latter task, however, still involves numerous methodological problems to solve.

“…In the context of frequent floods and droughts, the flood water resource utilization is an important measure to ensure water resource security in China. Most studies focused on flood disasters and forecast [2,3], flood risk and efficiency [4,5], and floodwater utilization and its assessment [6,7]. The guidelines of water resources governance had turned from "flood control" to "flood management".…”

Abstract:Water is the foundational natural resource and strategic economic resource, which plays an important role in maintaining ecosystem and environment. Considering that the flood water resources are a special form, the floodwater utilization is a special way of surface water resource utilization. Based on the hydrologic data from 1956 to 2010, this paper focuses on the study of flood water resources in the western of Jilin province, including analysis of the surface runoff, assessment of ecological basic flow, flood water resources availability and utilization potential of major rivers. The results show that the amount of flood water resources availability and utilization of Nen River, the second Songhua River and Taoer River is 45.73×10 ), meaning that flood water reources have a high potential to use. Then, The main characteristics and factors of flood water resources are analyzed in the study area. In additon, this paper presents several approaches for floodwater utilization to provide support for sustainable utilization of water resources in Western Jilin in future.
