The article deals with a tool for landslides susceptibility assessment as a function of the hydrogeological setting at different
scales. The study has been applied to a test area located in Southern Italy. First, a 3D groundwater flow model was implemented
for a large-scale area. The simulation of several groundwater conditions compared with the landslide activity map allows drawing
a hydrogeological susceptibility map. Then, a slope scale analysis was carried out for the Cavallerizzo landslide. For this
purpose, a 2D groundwater parametrical modeling was coupled with a slope stability analysis; the simulation was carried out
by changing the values of the main hydrogeological parameters (recharge, groundwater supply level, etc.). The results enabled
to connect the slope instability to some hydrogeological characteristics that are easy to survey and to monitor (e.g., rainfall,
piezometrical level, and spring discharge), pointing out the hazard thresholds with regards to different triggering phenomena. 相似文献

Water vulnerability assessment in karst environments: a new method of defining protection areas using a multi-attribute approach and GIS tools (EPIK method) 总被引：42，自引：12，他引：30
Groundwater resources from karst aquifers play a major role in the water supply in karst areas in the world, such as in Switzerland.
Defining groundwater protection zones in karst environment is frequently not founded on a solid hydrogeological basis. Protection
zones are often inadequate and as a result they may be ineffective. In order to improve this situation, the Federal Office
for Environment, Forests and Landscape with the Swiss National Hydrological and Geological Survey contracted the Centre of
Hydrogeology of the Neuchatel University to develop a new groundwater protection-zones strategy in karst environment. This
approach is based on the vulnerability mapping of the catchment areas of water supplies provided by springs or boreholes.
Vulnerability is here defined as the intrinsic geological and hydrogeological characteristics which determine the sensitivity
of groundwater to contamination by human activities. The EPIK method is a multi-attribute method for vulnerability mapping
which takes into consideration the specific hydrogeological behaviour of karst aquifers. EPIK is based on a conceptual model
of karst hydrological systems, which suggests considering four karst aquifer attributes: (1) Epikarst, (2) Protective cover,
(3) Infiltration conditions and (4) Karst network development. Each of these four attributes is subdivided into classes which
are mapped over the whole water catchment. The attributes and their classes are then weighted. Attribute maps are overlain
in order to obtain a final vulnerability map. From the vulnerability map, the groundwater protection zones are defined precisely.
This method was applied at several sites in Switzerland where agriculture contamination problems have frequently occurred.
These applications resulted in recommend new boundaries for the karst water supplies protection-zones.

In compilation of 1: 50 000 hydrogeological map, Some principles which are suitable for hydrogeological characteristics in China have been defined. Groundwater development and protection have been regarded as equally important. Some key problems such as classification of water-bearing formation, water yield property, color system and color scale of water yield property of water-bearing formation, expression of groundwater system, expression of hydrogeological parameters have been solved. This standardizing work can lay solid foundation for integration of 1: 50 000 synthetic hydrogeological map achievement and data, so as to broaden the service areas of hydrogeological survey. 相似文献

The aim of this research is to determine the relationship between groundwater flow and water quality of different ground and
surface water basins in the southwest Turkey. In addition, groundwater vulnerability is assessed taking into consideration
groundwater flow and quality. The autochthonous Beydaglari limestone is the major karstic aquifer in the region. According
to the groundwater level map of alluvium aquifers in the basins, groundwater discharge toward the carbonate aquifer is direct
and indirect. The hydrogeological connection between ground and surface water basins occurs via the karstic aquifer located
at the bottom of the alluvium bottom. In Egirdir lake, water also discharges in the karstic aquifer via karstic sinkholes
at the western border of the lake. In the research area, general groundwater discharge is toward the Mediterranean Sea by
means of autochthonous carbonate system, according to hydrogeological investigations, research of lineament and hydraulic
conductivities. This result is supported by the locations of lineaments and shore springs discharging from the limestone.
In addition, spreading of contaminants via karstic aquifer to great distance has been clearly identified. 相似文献

The southern regions of Madagascar have the country’s lowest water supply coverage and are highly vulnerable to drought. Access to potable drinking water is a major challenge for the local population. Chronic droughts lead to annual emergency appeals to save the lives of acute malnourished children. UNICEF’s response consisting in providing potable drinking water through the drilling of boreholes has been challenged by the complex hydrogeology, the low yield of boreholes and high-level salinity of water, the lack of reliable groundwater data and the weak capacity of the drilling sector. These constraints result in a high rate of drilling failure. To improve drilling success and provide more potable drinking water to local communities, it is vital to undertake reliable groundwater investigation.UNICEF Madagascar and the European Union delegation in Madagascar collaborated on the use of satellite imagery to improve sector knowledge and access to safe and clean water for local communities in southern Madagascar. The methodology relies on produce thematic layers of groundwater potential areas. Later, these thematic layers were overlaid with ground-based hydrogeological data to map the groundwater potential zones (GWP) and identify the most suitable sites for borehole siting and drilling. Findings of this study are very encouraging, and the integrated approach used has proven its applicability in mapping groundwater potential areas in the eight drought-affected areas of south Madagascar. The groundwater potential zone map is being used by UNICEF and partners to plan water supply projects and identify the best sites for positioning new boreholes and reduce the likelihood of drilling failure. Additionally, the project developed a database of groundwater resources, which will improve knowledge of the regional hydrogeological context and strengthen the capacity of the water sector. Lessons learnt from this study show that an integration of the groundwater potential zone map with demographics and water demand information will help identifying priority areas for detailed studies. Moreover, a capacity building activity is required for knowledge/technology transfer to the Ministry of Energy, Water and Hydrocarbons (MEEH), allowing the possibility of scaling-up this integrated approach to the rest of Madagascar. Finally, strengthening the capacity of the MEEH and refining this approach as suggested above will certainly help in the pursuit to improve equitable access to safe and clean water for households located in the drought-affected areas of southern Madagascar, allowing them to be more resilient to the effects of climate change. 相似文献

Assessment of shallow groundwater vulnerability in Dahei River Plain based on AHP and DRASTIC 
下载免费PDF全文
下载免费PDF全文 Based on the special hydrogeological conditions of the Dahei River Plain in the Inner Mongolia area, assessment of shallow groundwater vulnerability is conducted based on DRASTIC model. Each evaluation indicator weight is determined by using analytic hierarchy process (AHP). The most important indicators are lithology in soil media and vadose zone. Assessment model of shallow groundwater vulnerability of the Dahei River plain is constructed. Distribution map of vulnerability index in this area is made with the spatial analysis function of ARCGIS. The results show that the particularly sensitive area is the piedmont of the Daqing Mountain, where the upstream place of the groundwater and the south-central place of the plain has the lowest vulnerability. The assessment results are more in accordance with the actual vulnerability conditions of this area by using analytic hierarchy process, and is helpful for groundwater protection. 相似文献
