Integrated management of surface water and groundwater can provide efficient and flexible use of water through wet and dry periods, and address the impacts of water use on other users and the environment. It can also help adaptation to climate variation and uncertainty by means of supply diversification, storage and exchange. Integrated water management is affected by surface water and groundwater resources and their connections, water use, infrastructure, governance arrangements and interactions. Although the Murray–Darling Basin is considered to be a leading example of integrated water management, surface water and groundwater resources are generally managed separately. Key reasons for this separation include the historical priority given to surface water development, the relative neglect of groundwater management, shortfalls in information about connections between groundwater and surface water and their impacts, gaps and exemptions in surface water and groundwater use entitlements and rules, coordination problems, and limited stakeholder engagement. Integration of surface water and groundwater management can be improved by the establishment of more comprehensive water use entitlements and rules, with extended carry-over periods and legislated rules for aquifer storage and recovery. Collective surface water and groundwater management offers greater efficiency and better risk management than uncoordinated individual action. There are opportunities for more effective engagement of stakeholders in planning and implementation through decentralized catchment scale organizations.

AbstractThe article presents the influence of natural and anthropogenic factors on the chemical and physical properties of surface water and groundwater in the area of the city of Inowrocław. It has been shown that the properties of the waters were most strongly affected by the specific geological structure (the city is located within the Zechstein salt dome) as well as the long-term influence of a salt mine and soda plant. The composition of most analysed samples was dominated by Ca2+, Na+and Cl−ions. In places of heavy industrial activity, some water parameters were several time higher than permissible limit values according to Polish standards. It is concluded that, due to the threat to the city’s drinking groundwater resources and fertile soils, the surface water and groundwater in the area in question require permanent monitoring.

Surface Water And Groundwater

Abstract The study of surface water and groundwater (SGW) interaction can be used to improve water resource management. Herein, annual and monthly interactions in the Taoer River alluvial fan were calculated for the 1956–2014 period using the surface water balance method and the groundwater balance method, and a statistical model of interaction was obtained. The SGW interaction is shown in terms of the recharge of groundwater by surface water. From 1956 to 2014, the amount of SGW interaction in the study area varied greatly, averaging 27,848.4 × 104m3 annually. SGW interaction decreased gradually from the 1950s to the 1980s, and increased gradually from the 1980s to the present. During an individual year, SGW interaction increases gradually from January to July, peaking in July, and decreases gradually from August to December. An annual and a monthly multivariate regression statistical model were established. R2 was 0.697 for the annual model and 0.405 for the monthly model; the annual interaction model is more reliable. The model can be used to predict future trends in SGW interaction, which could be of great significance to the management of groundwater resources in the study area.

Abstract. To sustain growing food demand and increasing standard of living, global water withdrawal and consumptive water use have been increasing rapidly. To analyze the human perturbation on water resources consistently over large scales, a number of macro-scale hydrological models (MHMs) have been developed in recent decades. However, few models consider the interaction between terrestrial water fluxes, and human activities and associated water use, and even fewer models distinguish water use from surface water and groundwater resources. Here, we couple a global water demand model with a global hydrological model and dynamically simulate daily water withdrawal and consumptive water use over the period 1979–2010, using two re-analysis products: ERA-Interim and MERRA. We explicitly take into account the mutual feedback between supply and demand, and implement a newly developed water allocation scheme to distinguish surface water and groundwater use. Moreover, we include a new irrigation scheme, which works dynamically with a daily surface and soil water balance, and incorporate the newly available extensive Global Reservoir and Dams data set (GRanD). Simulated surface water and groundwater withdrawals generally show good agreement with reported national and subnational statistics. The results show a consistent increase in both surface water and groundwater use worldwide, with a more rapid increase in groundwater use since the 1990s. Human impacts on terrestrial water storage (TWS) signals are evident, altering the seasonal and interannual variability. This alteration is particularly large over heavily regulated basins such as the Colorado and the Columbia, and over the major irrigated basins such as the Mississippi, the Indus, and the Ganges. Including human water use and associated reservoir operations generally improves the correlation of simulated TWS anomalies with those of the GRACE observations.

To analyze the human perturbation on water resources consistently over a large scale, a number of macro-scale hydrological models (MHMs) have been developed over the recent decades. However, few models consider the feedback between water availability and water demand, and even fewer models explicitly incorporate water allocation from surface water and groundwater resources. Here, we integrate a global water demand model into a global water balance model, and simulate water withdrawal and consumptive water use over the period 1979–2010, considering water allocation from surface water and groundwater resources and explicitly taking into account feedbacks between supply and demand, using two re-analysis products: ERA-Interim and MERRA. We implement an irrigation water scheme, which works dynamically with daily surface and soil water balance, and include a newly available extensive reservoir data set. Simulated surface water and groundwater withdrawal show generally good agreement with available reported national and sub-national statistics.
