In Pakistan, on-demand availability of groundwater has transformed the concept of low and uncertain crop yields into more
assured crop production. Increased crop yields has resulted in food security and improved rural livelihoods. However, this
growth has also led to problems of overdraft, falling water tables and degradation of groundwater quality, and yields generally
remain well below potential levels. Over the last three decades, Pakistan has tried several direct and indirect management
strategies for groundwater management. However the success has been limited. This paper argues that techno-institutional approaches
such as introducing water rights, direct or indirect pricing and permit systems are fraught with difficulties in Pakistan
due to its high population density and multitude of tiny users. Therefore there is a need to develop frameworks and management
tools that are best suited to Pakistani needs. Pakistan should follow both supply and demand management approaches. For demand
management, adoption of water conservation technologies, revision of existing cropping patterns and exploration of alternate
water resources should be encouraged. For supply management, implementation of the groundwater regulatory frameworks developed
by Provincial Irrigation and Drainage Authorities (PIDAs) and introduction of institutional reforms to enhance effective coordination
between different organizations responsible for the management of groundwater resources should be given priority. 相似文献

GIS-Based Groundwater Management Model for Western Nile Delta 总被引:7,自引:3,他引:4
The limited availability of renewable fresh water is a major constraint on future agriculture and urban development in Egypt.
The main water resource that Egypt has been depending on is the River Nile. Nowadays, the role of groundwater is steadily
increasing and will cover 20% of the total water supply in the coming decades especially in the reclaimed areas along the
desert fringes of the Nile Delta and Valley. Abstraction from groundwater in Egypt is dynamic in nature as it grows rapidly
with the expansion of irrigation activities, industrialization, and urbanization. One of these areas is the Western Nile Delta
in which the groundwater is exploited in many localities. To avoid the deterioration of the aquifer system in this area, an
efficient integrated and sustainable management plan for groundwater resources is needed. Efficient integrated and sustainable
management of water resources relies on a comprehensive database that represents the characteristics of the aquifer system
and modeling tools to achieve the impacts of decision alternatives.
In this paper, a GIS-based model has been developed for the aquifer system of the Western Nile Delta. The GIS provides the
utilization of analytical tools and visualization capabilities for pre-and post-processing information involved in groundwater
modeling for the study area. The developed model was calibrated for steady state and transient conditions against the historical
groundwater heads observed during the last 20 yr. The calibrated model was used to evaluate groundwater potentiality and to
test two alternative management scenarios for conserving the aquifer system in Western Nile Delta. In the first scenario,
reducing the surface water inflow while increasing the annual abstraction from groundwater by about 450 million m3 and improving the irrigation system could increase the net aquifer recharge by about 5.7% and reduce the aquifer potentiality
by about 91%. Constructing a new canal as a second management scenario could increase the annual aquifer potentiality by about
23%. The GIS-based model has been proven to be an efficient tool for formulating integrated and sustainable management plan. 相似文献

This paper presents management of groundwater resource using a Bayesian Decision Network (BDN). The Kordkooy region in North East of Iran has been selected as study area. The region has been sub-divided into three zones based on transmissivity (T) and electrical conductivity (EC) values. The BDN parameters: prior probabilities and Conditional Probability Tables - CPTs) have been identified for each of the three zones. Three groups of management scenarios have been developed based on the two decision variables including “Crop pattern” and “Domestic water demand” across the three zones of the study area: 1) status quo management for all three zones represent current conditions; 2) the effect of change in cropping pattern on management endpoints and 3) the effect of future increased domestic water demand on management endpoints. The outcomes arising from implementing each scenario have been predicted by use of the constructed BDN for each of the zones. Results reveal that probability of drawdown in groundwater levels of southern areas is relatively high compared with other zones. Groundwater withdrawal from northern and northwestern areas of the study area should be limited due to the groundwater quality problems associated with shallow groundwater of these two zones. The ability of the Bayesian Decision Network to take into account key uncertainties in natural resources and perform meaningful analysis in cases where there is not a vast amount of information and observed data available – and opportunities for enabling inputs for the analysis based partly on expert elicitation,emphasizes key advantages of this approach for groundwater management and addressing the groundwater related problems in a data-scarce area. 相似文献

An Integrated Groundwater Management Mode Based on Control Indexes of Groundwater Quantity and Level 总被引:3,自引:1,他引:2
Groundwater is an important source of freshwater throughout the world. Due to over-exploitation of groundwater over many years, a number of potential adverse hydrogeological problems have raised. To reduce such adverse effects, it is necessary to carry out strict groundwater management in over-exploited areas. In this study, quantity-level binary control management mode has been developed in Tianjin. Initially, the management is the key to determine control levels of groundwater including the blue line levels (proper levels) and red line levels (warning levels), the blue line levels can be determined by the ground settlement recovery scenario, and the red line levels can be determined through planning groundwater exploitation scenarios. By comparing the real-time observed groundwater data with the blue levels and red levels the management grade of groundwater levels which are present, can thus be identified. Secondly, the corresponding management strategies would be determined by the management grade. On this basis reasonable groundwater levels and mining schemes can be made. Finally, the water quota for each sector can be optimized and adjusted in real time according to the binary groundwater management methodology established in this study. Thus, the exploitation of groundwater can be monitored and dynamically managed by the real-time monitoring levels and the sustainable utilization of groundwater resources can be achieved. To achieve all the objectives mentioned above, it is necessary to provide a powerful tool through the utilization of a numerical model for groundwater management. Based on geological and hydrogeological conditions in Tianjin city, a three-dimensional numerical groundwater flow model was established by coupling a one-dimensional soil consolidation model with MODFLOW model. Through calibration and verification, the model showed good simulation accuracy. It proved that the new management mode can provide a scientific basis for groundwater management. 相似文献

Groundwater resources are steadily subjected to increasing water demands. The aquifers are considered as the most accessible source of fresh water. In recent years, they have been faced with severe water withdrawal in arid and semi-arid countries like Iran and thus some aquifers was considered as forbidden aquifers that it means the water withdrawal from these aquifers is unauthorized. Given a critical situation, groundwater resources management in the form of tools such as monitoring the level of the aquifers and developing the restoring scenarios is essential. Therefore, for this purpose, a framework has been developed based on prediction of groundwater level using Bayesian Networks (BNs) model. Furthermore, Multi Criteria Decision Making methods (MCDM) techniques proposed and employed for ranking of proposed groundwater management scenarios. This framework was evaluated for restoring the Birjand aquifer in Iran in different hydrological conditions. A probabilistic Dynamic BN was proposed for groundwater level prediction under uncertainties. After analyzing the obtained results, the applicable short term scenarios for groundwater management as well as appropriate economic, social and technical criteria were defined for decision making procedure. Then, using elicitation of decision makers’ opinions on the relative importance and performance of criteria, SAW, TOPSIS and PROMETHEE-II techniques were applied to rank the scenarios and the obtained results were aggregated by Borda method for final ranking of the scenarios. Lastly, the final results demonstrates the capability of the proposed framework for groundwater resources planning and management which can be employed for reducing the risk of aquifer level declining. 相似文献
